Senior Software Engineer - Full Stack

Senior Software Engineer

Our client is looking for a full-time Senior Software Engineer to join their Phoenix-local team (No C2C). This team is on-site four days per week. This company builds AI-powered software tools that keep critical infrastructure reliable, efficient, and safe. Their software integrates AI-driven workflow, documentation, and research automation. You'll ship production code operators and engineers rely on every day. We're growing quickly, expanding our team and our Phoenix HQ. The work is consequential: what you build helps real plants run safer and smarter.

What You'll Do:

• You'll own features end-to-end across a modern Python/React stack, with a heavy dose of reliability, data plumbing, and "meet the enterprise where it is" integration work.
• Ship production features across React (frontend) and Python FastAPI (backend) that power our products (e.g., CAP AI, AtomAssist).
• Design and evolve APIs and Postgres schemas for performance, correctness, and auditability (migrations, indexing/partitioning, background data corrections).
• Containerize and deploy services with Docker/Podman and Kubernetes; help tune queues/workers (Redis, RabbitMQ, Celery) for throughput, reliability, and idempotency.

What Makes You a Great Fit:

• Degree in CS or related field or equivalent practical experience.
• You've shipped production React + Python FastAPI and can contribute independently within ~6 weeks.
• You care about correctness and safety: typed APIs, schema migrations with backfills, idempotent jobs, and tests that catch the sharp edges.
• You're comfortable with customer-facing engineering (a quick demo, a clarifying question, a pragmatic workaround).
• Clear, direct communicator; kind reviewer; steady under pressure.
