Senior Software Engineer – AI; Agent Systems

Senior Software Engineer – AI (Agent Systems) | Bay Area (Hybrid) | $180K–$260K + equity

I’m partnering with a high-growth SaaS company building production-grade AI systems that actually execute work — not just assist it.

This is not a “build a model and ship it” role.

This is where you design and own agent systems that retrieve context, make decisions, and complete workflows end-to-end in production
.

You’ll operate at the intersection of backend engineering, distributed systems, and applied AI
, shaping how real-world AI systems behave at scale.

• Build agent-based architectures that take action across complex workflows
• Design backend systems in Python / Node.js (APIs, services, orchestration layers)
• Develop multi-step reasoning systems (tool use, state management, execution loops)
• Implement RAG pipelines and improve retrieval + grounding
• Create evaluation + observability frameworks to measure system reliability
• Debug failure modes across retrieval, reasoning, and agent execution
• Ship full-stack features with Type Script / React where needed

• 5–8+ years in backend or full-stack software engineering
• Proven experience shipping AI systems in production (agents, RAG, workflows)
• Strong system design fundamentals (APIs, distributed systems, scalability)
• Hands‑on with LLMs beyond basic API usage
• Python or Type Script expertise
• Engineers who can explain why systems work (or fail) — not just build them
