Infrastructure developer (rails/postgres) — heavy-materials & construction tech (remote, india)

You will own the stability and speed of our production system. You will make the platform faster, cheaper, and more reliable—then prove it with numbers.
What you will own
- Postgre SQL performance & reliability: query plans, indexes, partitioning, connection pooling, replication, backups, slow query triage; functions/triggers (we use the fx gem heavily)
- Containers: Docker/Build Kit, multi-stage builds, base images, smaller images, faster builds
- CI/CD: build caching, test parallelization (turbo_tests), deployment workflows
- Paa S operations (Render or similar): service configs, autoscaling, environment management, zero-downtime deploys
- Observability: error tracking, performance monitoring, logs, alerting
- Background jobs: queue health, throughput, failure handling, worker scaling
- Security: secrets, dependency updates, vulnerability scanning
You are a fit if
- You can take a slow Postgres-backed endpoint and make it fast (and keep it fast)
- You...
