• Familiarity with CI/CD pipelines, Git-based workflows, and deployment practices.
• Ability to work independently, move quickly, and make sound engineering tradeoffs.

Preferred Qualifications

• Experience with workflow orchestration, agent-based systems, or automation pipelines.
• Experience with Docker, cloud infrastructure, and containerized environments.
• Familiarity with background job systems, queues, and event-driven architectures.
• Experience building internal platforms, QA tooling, evaluation frameworks, or developer productivity tools.
• Exposure to LLM/AI workflow orchestration, RPA, or test automation systems.
• Experience with observability tools, telemetry, and production monitoring.

What Success Looks Like

• You can ship polished frontend and backend features end-to-end. 
• You can build robust harnesses that make systems easier to test, measure, debug, and scale.
• You improve both product delivery and engineering leverage.
• You help the team move faster by making complex workflows repeatable and reliable.

Ideal Candidate Profile

You are more than a feature engineer; you think in systems and ask:
- How do we test this?
- How do we simulate this?
- How do we validate edge cases?
- How do we make this reproducible?
- How do we instrument this so it can be trusted in production?

You enjoy building the glue, scaffolding, and runtime support that transform experimental ideas into dependable products.
