• Demonstrated use of AI/LLM tooling in professional or side projects.
• Curiosity and creativity in exploring agentic workflows and autonomous development approaches.
• Strong communication skills and ability to collaborate across remote‑first teams.

• Experience with multi‑agent frameworks, orchestration tools, or AI‑powered application platforms.
• Knowledge of service‑mesh, observability tooling, and policy‑as‑code.
• Familiarity with event‑driven systems (Kafka, NATS) and domain‑driven design.
• Exposure to safety, ethics, and compliance considerations in AI systems.
• Remote‑first with optional hub meet‑ups; hardware & co‑working stipend.
• Flexible core hours (overlap 9 a.m. 3 p.m. ET).
