Overview

DevOps / Site Reliability Engineer Engineering

Responsibilities

• You will own Terraform modules across our AWS infrastructure compute, networking, databases, IAM, DNS and build the GitHub Actions pipelines that ship our Django, Python, Node.js, and React services.
• This role suits someone who wants deep infrastructure work with production ownership and prefers building over ticket-shuffling.
• Infrastructure as Code
• Own and extend Terraform modules across AWS ECS/Fargate or EKS, RDS, VPC networking, IAM, ALB/NLB, S3, Route 53, CloudWatch. Manage Terraform state safely; write and review plans that reviewers can trust. Eliminate manually created resources by bringing them under code (via terraform import, refactors, and module extraction). Keep environments (dev, QA, production) consistent and reproducible.
• CI/CD Engineering
• Build and maintain GitHub Actions pipelines for build, test, containerization, and deployment. Migrate legacy pipelines (Jenkins, CircleCI, GitLab CI) onto a single, maintainable platform. Design safe deployment paths staged rollouts, health-gated releases, fast and reliable rollback. Keep pipelines fast: caching, parallelism, test splitting, and honest gating.
• Reliability & Operations
• Own the production change window on your shift: deploys, migrations, cutovers, and maintenance. Run and improve observability dashboards, SLOs, alerting that fires on real user impact rather than noise. Debug containerized applications in production: logs, metrics, traces, resource limits, networking. Participate in on-call rotation and incident response; drive blameless post-incident reviews. Improve cost efficiency and resource utilization across the AWS footprint.
• Databases & Data Services
• Operate PostgreSQL in production read query plans, identify slow queries, understand connections, locks, and replication. Plan and execute schema migrations against live systems with minimal disruption. Operate supporting data services: Redis/ElastiCache, message brokers, object storage.
• Automation & Tooling
• Write Python and shell automation to remove repetitive operational work. Build tooling that makes the wider team faster self-service scripts, runbooks, guardrails. Harden secrets handling, access control, and infrastructure security posture.
• Handover & Communication
• Write clear, complete handover notes at the end of every shift. Where shifts do not overlap, your writing is how the rest of the team learns what happened. Maintain runbooks and infrastructure documentation as systems change. Coordinate with the wider engineering team on planned work and follow-ups.
• AI-Enabled Engineering
• Use modern AI tools to accelerate infrastructure work, scripting, and troubleshooting. Apply AI-assisted practices while maintaining strong engineering, security, and review standards.
