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 • PostgreSQL performance & reliability: query plans, indexes, partitioning, connection pooling, replication, backups, slow query triage; functions/triggers (we use the fx gem heavily) • Containers: Docker/BuildKit, multi-stage builds, base images, smaller images, faster builds • CI/CD: build caching, test parallelization (turbo_tests), deployment workflows • PaaS 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 are comfortable debugging production incidents under pressure • You think in reliability, telemetry, and cost-per-transaction • You prefer operational impact over UI work What you will get • Work from anywhere, on your rhythm — Day-to-day is async and flexible. When production needs hands-on attention, you are expected to be available. • Stability and long-term runway — An established, growing company with a steady platform and clear priorities. • Hard problems, real ownership — You will own core reliability and performance outcomes. • Serious technical growth — You will work across Postgres, CI/CD, containers, observability, and scaling. The role naturally expands your depth. • AI-first engineering culture — We expect you to use AI as a force multiplier for investigation, design, implementation, and operational playbooks. • Autonomy with high trust — Clear outcomes, minimal micromanagement. About XBE  XBE builds business-operations software based in the US, for heavy-materials, logistics, and construction companies that should be generating far more profit than they do today—fully remote, high-trust, and run on ownership, collaboration, and clear outcomes. Our team is fully remote and global.
