We’re hiring a remote, contract-based Backend & Infrastructure Engineer who can build and run production systems end-to-end.
You will build and scale high-throughput backend services in Golang and Python, operate ClickHouse-powered analytics at scale, manage Linux servers for maximum uptime, scalability, and reliability, and drive cost efficiency as a core engineering discipline across the entire stack.
What You Will Do:
Backend Development (Golang & Python)
- Design and maintain high-throughput RESTful/gRPC APIs — primarily Golang, Python for tooling and supporting services
- Architect for horizontal scalability, fault tolerance, and low-latency at scale
- Implement caching (Redis/Memcached), rate limiting, efficient serialization, and CI/CD pipelines
Scalable Architecture & System Design
- Design and evolve distributed, resilient backend architecture that scales without proportional cost increase
- Make deliberate trade-offs (CAP, cost vs. performance) and design multi-region HA with automated failover
ClickHouse & Analytical Data Infrastructure
- Deploy, tune, and operate ClickHouse clusters for real-time analytics and high-cardinality OLAP workloads
- Design optimal table engines, partition strategies, materialized views, and query patterns
- Manage cluster scaling, replication, schema migrations, and upstream/downstream integrations
Cost Efficiency & Cost Optimization
- Own cost optimization end-to-end: right-sizing, reserved/spot capacity, storage tiering, query optimization, compression, batching
- Build cost dashboards, budgets, and alerts; drive a culture of cost-aware engineering
Linux Server Management & Infrastructure
- Administer and harden Linux servers (Ubuntu, Debian, CentOS/RHEL) — patching, security, SSH, firewalls
- Manage VPS/bare-metal provisioning, capacity planning, and containerized workloads (Docker, Kubernetes/Nomad)
- Implement Infrastructure-as-Code (Terraform/Pulumi); optionally manage AWS/GCP as needed
Data, Storage & Scheduling
- Optimize SQL schemas and queries (PostgreSQL, MySQL); manage data archival, cold storage, and lifecycle policies
- Build and maintain cron jobs, scheduled tasks, and batch processing systems
Uptime, Reliability & Observability
- Own system uptime: zero-downtime deployments, health checks, self-healing infra, SLOs/SLIs
- Build observability stacks (Prometheus, Grafana, Datadog, OpenTelemetry); structured logging, distributed tracing, alerting
- Drive incident response, root cause analysis, and post-mortems
Required Qualifications:
Must-Have (Critical)
- Deep proficiency in Golang (primary) and Python
- Proven ability to design and build scalable, distributed architectures
- Production experience deploying and operating ClickHouse at scale
- Track record of driving measurable cost efficiency and cost optimization

Also Required
- Strong Linux server administration (Ubuntu, Debian, CentOS/RHEL) — comfortable living in the terminal
- Proven uptime and reliability track record across production infrastructure
- Strong SQL (PostgreSQL, MySQL); experience with high-throughput APIs (10K+ RPS)
- VPS/bare-metal provisioning, Docker, Kubernetes/Nomad, IaC (Terraform/Pulumi)
- Observability tooling (Prometheus, Grafana, Datadog, OpenTelemetry)
- Cron jobs, batch processing, data archival, cold storage management
- Networking fundamentals (DNS, TCP/IP, load balancing, TLS)
Nice to Have
- AWS, GCP, or other major cloud provider experience
- Message queues / event streaming (Kafka, RabbitMQ, SQS/SNS)
- Data pipelines (Airflow, dbt); FinOps practices
- Open-source contributions; compliance background (SOC 2, HIPAA, GDPR)
