Senior Database Developer (Oracle to PostgreSQL)
Mactores is the agent-native AWS modernization firm. Most modernization work doesn't ship, it stalls in pilots, slips a year, or lands at three times the budget. We exist to ship it: production systems running, legacy retired, outcomes measured. Our delivery is built on Aedeon, the agent platform built by Mactores' founders' sister company, which absorbs the repetitive 60–70% of engagement work, discovery, dependency mapping, validation, test generation, that traditional consulting bills human hours against. Forward-deployed engineers own the rest: architecture, judgment, and cutover, on dates we commit to in the contract.
We are seeking an experienced Senior Database Developer to lead and support Oracle to PostgreSQL/Aurora PostgreSQL migration initiatives. The role involves deep hands-on work across SQL refactoring, schema conversion, DMS operations, performance tuning, and post–go-live stabilization.

What you will do?
- Refactor and convert Oracle SQL, PL/SQL, and database objects to PostgreSQL-compatible SQL/PLpgSQL.
- Analyze and remediate AWS SCT (Schema Conversion Tool) findings and limitations.
- Manage and maintain Flyway migration codebase (versioned scripts, repeatable migrations, rollbacks).
- Identify, troubleshoot, and fix database-related application bugs.
- Perform query optimization for PostgreSQL (execution plans, indexing strategies, query rewrites).
- Support and monitor AWS DMS during full load and CDC phases.
- Diagnose and resolve DMS data and performance issues.
- Perform data validation and reconciliation between Oracle and PostgreSQL.
- Collaborate with application teams to align SQL behavior and performance expectations.
What are we looking for?
- Bachelor's degree in Computer Science or a related field.
- 5+ years of experience as an Oracle/PostgreSQL DBA and database developer.
- Strong experience with Oracle Database and PostgreSQL / Aurora PostgreSQL.
- Hands-on expertise in Oracle to PostgreSQL migration.
- Advanced SQL and query performance tuning skills.
- Experience with AWS SCT and AWS DMS.
- Knowledge of Flyway/Liquibase or similar schema migration tools.
- PostgreSQL internals: indexing, statistics, execution plans.
- AWS services: RDS/Aurora, CloudWatch, IAM (preferred).
You will be preferred if:
- Familiarity with automation and configuration management tools, such as Ansible, Chef, or Puppet.
- Familiarity with IAAC tools such as Terraform, CloudFormation.
- Familiarity with CI/CD implementation tools like Liquibase/Flyway.

Senior Database Administrator (DBA)
Database Reliability & Performance • Senior Individual Contributor
- Experience: 6–9 years in production database administration / engineering
- Level: Senior Individual Contributor (hands-on)
- Function: Data Platform — reliability, performance, and governance across relational and distributed SQL & NoSQL DBs.
About the Role
We are hiring a Senior Database Administrator to own the health, performance, and reliability of the data layer behind a high-scale, multi-tenant platform. Our environment spans several independent PostgreSQL database instances, a cache-first read tier, change-data-capture pipeline, analytics and archival stores. Should be capable of implementing NoSQL stores (Cassandra / ScyllaDB) & MySQL end to end as we scale.
This is a hands-on senior IC role for someone who has run demanding production databases and wants full ownership: partitioning and maintenance, performance tuning, monitoring, uptime, disaster recovery, and the security and data-governance documentation that keeps a regulated, multi-tenant platform audit-ready. You will work closely with, and take direction from, engineering leadership — translating priorities into a well-run, well-documented data platform.
What You'll Own
PostgreSQL Depth
- Administer multiple production PostgreSQL instances (v16+), including schema/DDL review, migrations, and release coordination.
- Design and maintain table partitioning strategies (range/hash/time-based) and automate partition lifecycle — creation, retention windows, and safe drops.
- Own query and instance performance tuning: EXPLAIN/ANALYZE, indexing strategy, autovacuum/bloat management, connection pooling (e.g. PgBouncer), and parameter-group tuning.
- Execute zero-downtime schema changes using expand–migrate–contract / blue-green patterns; assess lock impact and avoid long ACCESS EXCLUSIVE locks on hot tables.
- Manage replica topology (writer/reader endpoints), replication lag, and read-scaling as load grows.
- Partner with app teams on migration tooling (e.g. Flyway) and paired forward/rollback scripts; enforce idempotent, reviewed, tested DDL.
NoSQL & Scale
- Data-model, deploy, and operate distributed NoSQL clusters — Cassandra and/or ScyllaDB — including partition/clustering key design, compaction strategy, repair, and node operations (bootstrap, decommission, scale-out).
- Lead the planned migration of high-volume payload tables from partitioned PostgreSQL to Cassandra/ScyllaDB: capacity planning, dual-write/backfill design, cutover, and validation.
- Tune distributed-store read/write paths, consistency levels, and cluster sizing for predictable latency at scale.
- Support the cache-first architecture (Redis) and change-data-capture / streaming pipelines (e.g. Kafka) that move data to analytics and cold-archival stores.
Operations, Reliability & DR
- Own database uptime and SLOs; build and maintain monitoring, alerting, and dashboards for the key signals (latency, replication lag, CPU/IO, connections, vacuum lag, error rates).
- Define and regularly test backup and disaster-recovery strategy — RPO/RTO targets, point-in-time recovery, restore drills, and cross-AZ / future multi-region readiness.
- Drive incident response for database-related issues: triage, mitigation, root-cause analysis, and follow-up actions.
- Write and maintain runbooks (partition maintenance, failover, archival, DR, migration procedures) and participate in an on-call rotation for the data layer.
- Establish production-change discipline: pre-flight and post-deploy verification, rollback criteria, and backup verification before destructive operations.
Security, Governance & Documentation
- Implement and maintain database access control — least-privilege roles, schema-scoped permissions, and row-level security (RLS) for multi-tenant isolation.
- Own data-governance documentation: PII maps, per-table retention policies, audit-readiness, and the controls behind privacy-regulation compliance (e.g. GDPR / DPDP-style erasure and legal-hold workflows).
- Author and maintain architecture decision records (ADRs), schema documentation, and monitoring/runbook docs so the data platform is legible to the wider team.
- Uphold encryption-at-rest/in-transit posture and safe handling of sensitive columns; keep the data layer aligned with the platform's compliance requirements.
Coding & Automation Bar (Required)
This role is automation-first, not click-ops. The right candidate treats repetitive database work as something to script away and can drop into application code when a problem demands it.
- Strong scripting in Python and Bash for automation of maintenance, backups, partition management, backfills, and health checks.
- Comfortable with infrastructure-as-code (e.g. Terraform) and configuration management (e.g. Ansible) for reproducible database infrastructure.
- Solid SQL and PL/pgSQL; able to read and debug application-layer database code and, worst case, write or patch application code (e.g. Python/Node/Java) to unblock a fix.
- Fluent with Git-based workflows, code review, and CI for database migrations and tooling.
Required Qualifications
- 6–9 years operating relational databases in demanding production environments, with deep PostgreSQL expertise (internals, partitioning, replication, performance tuning).
- Hands-on experience running at least one distributed NoSQL store in production — Cassandra or ScyllaDB strongly preferred (other wide-column/distributed stores considered).
- Proven ownership of backup/DR, monitoring, and incident response for production databases.
- Strong scripting/automation background (Python, Bash) and experience with IaC.
- Experience with managed cloud databases (AWS RDS or equivalent) and understanding of instance/parameter-group tuning, replicas, and failover.
- Experience designing for multi-tenancy and data isolation at scale.
- Clear written communication — able to produce runbooks, ADRs, and governance docs a team can rely on.
Nice to Have
- Experience migrating workloads from PostgreSQL to Cassandra/ScyllaDB (or similar relational-to-distributed migrations).
- Familiarity with Redis as a cache tier and with CDC / streaming pipelines (e.g. Kafka, Debezium).
- Exposure to Flyway (or Liquibase), pgTAP or similar schema testing, and PgBouncer.
- Working knowledge of privacy regulations (GDPR, India DPDP) and audit/compliance processes.
How You Work
- Ownership mindset — takes a directive and runs it to done, with sound judgment on trade-offs.
- Reliability-first and detail-oriented; disciplined about verification, rollback, and documentation.
- Collaborative in a high-performing engineering team; communicates clearly with developers and leadership.
- Pragmatic and scale-aware — designs for where the platform is going, not just where it is.

Mactores is the agent-native AWS modernization firm. Most modernization work doesn't ship, it stalls in pilots, slips a year, or lands at three times the budget. We exist to ship it: production systems running, legacy retired, outcomes measured. Our delivery is built on Aedeon, the agent platform built by Mactores' founders' sister company, which absorbs the repetitive 60–70% of engagement work, discovery, dependency mapping, validation, test generation, that traditional consulting bills human hours against. Forward-deployed engineers own the rest: architecture, judgment, and cutover, on dates we commit to in the contract.
Enterprises stuck on Oracle carry license renewals, vendor-specific SQL nobody wants to touch, and application layers welded to the database underneath them. This role sits in our Application & Database Modernization pillar: you'll work an Oracle-to-PostgreSQL migration where Aedeon handles the mechanical conversion at scale and you own what the tools can't, which is the refactoring judgment inside large enterprise Java codebases.
You'll rewrite the SQL the application actually depends on, align it with the modernized schema, prove functional parity, and see the application through production cutover. Not a proof of concept. A system that ships.
What you will do?
- Decompose a large Java monolith into microservices: identify bounded contexts, extract services with the strangler-fig pattern, and define REST and event contracts.
- Apply proven microservice patterns: database-per-service (staged pragmatically), Saga with compensating actions, transactional outbox, idempotent consumers, and resilience patterns such as circuit breakers.
- Remediate Oracle- and SQL Server-specific code for Aurora PostgreSQL: rewrite embedded SQL, stored procedure calls, sequences, pagination, date handling and error handling, and update JPA/Hibernate or MyBatis mappings.
- Work closely with database migration engineers so application-layer SQL lines up with the converted target schema and supports environment cloning and refresh.
- Deploy and run services on Amazon EKS: Helm charts, health probes, JVM and resource tuning, autoscaling, ALB/NLB ingress, and Pod Identity for AWS access.
- Build and maintain GitHub Actions CI/CD pipelines for Java services: Maven/Gradle builds, scanned images in Amazon ECR, Flyway/Liquibase migrations, and promotion from dev to prod with approval gates and rollback.
- Automate testing: unit, Testcontainers integration, contract, API and smoke tests, plus parity and performance tests that prove modernized services match or beat legacy baselines. Wire the client's existing suites into the pipeline.
- Use GenAI-assisted tools (Claude Code) to accelerate code conversion, and validate their output rigorously.
- Instrument services for Dynatrace and support production cutover: rehearsals, validation, rollback planning and stabilization.
- Produce engineering documentation that outlives the engagement: design notes, code-migration runbooks, troubleshooting guides and knowledge-transfer material for the client's teams.
- Pair with client engineers and SMEs across US- and India-based teams, reviewing code and keeping business logic aligned.
What are we looking for?
- Bachelor's degree in Computer Science, Engineering, or a related field.
- 5+ years of professional Java development experience (Java, Spring Boot, Spring Cloud, JDBC, JPA/Hibernate or MyBatis).
- Hands-on experience decomposing a monolith into microservices in production: domain-driven design, Saga and event-driven integration (Kafka, SQS/SNS or EventBridge).
- Strong SQL expertise. You can analyze, optimize and rewrite complex SQL embedded in Java, and you've migrated application code from Oracle or SQL Server to PostgreSQL.
- Deep understanding of JDBC, ORMs, transaction management, connection pooling and database-driven application flows.
- Production experience running Spring Boot on Kubernetes (preferably Amazon EKS) with Docker and Helm.
- CI/CD experience with GitHub Actions: reusable workflows, environment approvals and OIDC authentication to AWS.
- Test automation skills: JUnit 5, Mockito, Testcontainers, REST Assured and consumer-driven contract testing.
- Working knowledge of AWS application services: Aurora PostgreSQL, RDS Proxy, KMS and IAM roles for workloads.
- Regular use of AI coding assistants in real delivery work.
- Excellent spoken and written English, and the ability to work US Mountain Time business hours with globally distributed teams.
You will be preferred if you
- Have exposure to automated code-refactoring tools or GenAI-assisted remediation workflows.
- Have experience with Amazon VPC Lattice or a service mesh.
- Have done performance testing (Gatling, JMeter or k6) and worked with observability stacks (Dynatrace or OpenTelemetry).
- Have worked on MuleSoft integrations and Ping Identity (OAuth 2.0 / OIDC).
- Have worked in SOX-regulated environments: change control, approvals and audit evidence.
- Have worked on e-commerce, subscription ordering or commission/compensation systems.
- Hold an AWS certification (Developer Associate or Solutions Architect) and have basic Terraform.
Data Platform Engineer
Design, automate, and scale our data platform — this is an engineering role, not a traditional "DBA job.

- PostgreSQL (deep, hands-on — partitioning, replication, tuning)
- Any distributed NoSQL store (Cassandra, ScyllaDB, or similar wide-column/distributed DB) (real production experience)
- Python (automation & tooling, not just scripting)
- DevOps & CI/CD (building pipelines, not just using them)
- Terraform (infrastructure-as-code)
You'll:
- Design schemas, partitioning strategies, and lead the Postgres → Cassandra migration end-to-end
- Own PostgreSQL performance, replication, and zero-downtime schema changes
- Build Python-based automation to eliminate repetitive DB work
- Own CI/CD pipelines and Terraform-based infra provisioning
- Drive uptime, DR, monitoring, and incident response
