As a Senior Agentic AI Engineer at Eigen, you'll work on the core systems that make AI agents actually usable in production. You've built real things - distributed systems, APIs, developer tools - and you've gone deep on agents, LLM pipelines, or autonomous workflows. You're not just using AI tools - you have opinions on where this is going.
You will own large parts of the system and move quickly from idea → working product.
You will spend most of your time building. Not managing. Not talking about roadmaps. Building.
This is a full-time role, remote-friendly, with a preference for U.S. time zones and close collaboration with the Seattle-based team.
What You Will Do
Build agent runtimes and orchestration systems (planning, tool use, memory, coordination)
Make agents reliable (retries, failure handling, state management)
Make agents observable (tracing, debugging, evaluation)
Make agents cheap (cost-aware execution, performance optimization)
Make agents useful in production (not demos - real systems people depend on)
Integrate LLMs, APIs, and external data into coherent, working systems
Define how developers build, debug, and extend agent behavior
What You'll Bring
We care more about evidence than years of experience.
Show us you've built hard things that work.
Strong Signals
You've shipped real systems that people depend on
You've taken ambiguous problems and turned them into working products
You've built or deeply explored agent systems, LLM pipelines, or automation beyond simple demos
You understand system behavior in production - failure modes, tradeoffs, reliability
You move fast and iterate - you don't wait for perfect specs
Technical Foundation
Strong backend / systems experience (distributed systems, APIs, infrastructure)
Proficiency in at least one core language (Python, Go, TypeScript, Rust, etc.)
Experience with reliability patterns (state, retries, observability)
Comfort working across the stack when needed
Nice To Have
Experience with agent frameworks (LangChain, AutoGen, CrewAI, or custom systems)
Experience building multi-agent or orchestration systems
Familiarity with LLM evaluation, prompting, or performance tuning
Experience with workflow engines (Temporal, Airflow, Dagster)
Experience building developer platforms, SDKs, or internal tools
Exposure to retrieval systems, vector databases, or memory architectures
Interest in crypto, distributed systems, or verifiable compute
