• Understanding of secure coding practices, reliability, observability, automated testing, and production support.
• Ability to work in evolving problem spaces, learn emerging AI technologies, and deliver solutions iteratively, with guidance when needed.

Preferred Skills:

• Experience integrating LLMs, machine learning models, or AI services into software applications.
• Familiarity with agent frameworks, workflow engines, orchestration platforms, retrieval patterns, or AI evaluation tools.
• Exposure to audit-friendly, policy-driven platforms, guardrails, or responsible AI practices.
