Role Overview

We are seeking a hands-on Database Engineer with a "reliability mindset" to own the stability, performance, and scalability of our mission-critical data layer. You will manage high-velocity data stores in a dynamic e-commerce environment, focusing on Aerospike, Cassandra, or Redis. The ideal candidate combines deep database internals knowledge with strong automation skills (Python/Shell) to minimize toil and ensure 99.99%+ uptime.

Key Responsibilities

• Database Operations: Manage the full lifecycle of NoSQL clusters (Aerospike, Cassandra, Redis), including provisioning, upgrades, patching, and capacity planning.
• Reliability & Uptime: Maintain extremely high availability. Design and execute Disaster Recovery (DR) drills, manage cross-region replication, and ensure robust backup/restoration mechanisms are in place.
• Performance Tuning: Proactively monitor database performance. Troubleshoot and resolve complex functional and latency issues in a high-throughput environment.
• Automation & Tooling: Write production-grade Python scripts and Shell automation to handle routine tasks, database migrations, and monitoring alerts.
• Cloud & Infrastructure: Manage cloud infrastructure (AWS/GCP/Azure) and lead migrations across cloud providers or regions. Write and maintain detailed runbooks and Infrastructure-as-Code (IaC) configurations.
• Production Discipline: Execute production changes with strict adherence to change management protocols to zero-out downtime risks.

Required Qualifications

• Experience: 3–7 years of relevant experience in Database Engineering or Site Reliability Engineering (SRE).
• Core Tech Stack: Deep hands-on production experience with at least two of the following: Aerospike, Cassandra, or Redis.
• Scripting: Proficiency in Python and Shell/Bash scripting for automation and tool building.
• Cloud Native: Solid experience with cloud infrastructure (AWS, GCP, or Azure) and experience migrating databases between clouds or hybrid environments.
• Operational Excellence: Proven track record of maintaining high uptime (HA) systems, managing DR strategies, and writing comprehensive runbooks.

Preferred Qualifications

• Industry Background: Previous experience in E-commerce, Fintech, or similar high-traffic, low-latency industries.
• Methodology: Experience working in Agile/Scrum environments.
• Tooling: Familiarity with monitoring tools (Prometheus, Grafana, Datadog) and Configuration Management (Ansible, Terraform).

Why Join Us?

• Work on massive scale data problems.
• Competitive compensation and benefits.

Role Overview
