AI Agent Engineer
Every breach, every failed audit, every new hire stuck in onboarding purgatory traces back to the same question: who has access to what — and should they?
Identity is where modern companies break. Too much access leaks data. Too little grinds the business to a halt. Lumos is the industry's first Autonomous Identity Platform — software that doesn't just surface access risk, but acts on it. We started with a self-service AppStore and grew into the critical infrastructure connecting apps, identities, and data for GitHub, MongoDB, Mars, Pinterest, Anduril, Intercom, Roku, and Netskope. At the center is Albus, our AI agent for identity — mining roles, approving access, and catching the drift humans miss.
You'll ship work that thousands of IT and security teams touch every day. You'll own problems without playbooks, because the category is being redefined in real time — by us.
Why Lumos?
- 🚀 Jump on a rocketship. Since launching out of stealth in April 2022, we've grown from 20 to ~130 Alchemists and raised over $65M from a16z, Scale, Neo, Greg Brockman (President at OpenAI), and Phil Venables (CISO at Google).
- ⭐ Customers love us — and so does the industry. Named a Strong Performer in the 2026 Gartner Voice of the Customer for IGA — 4.7/5, with 96% of reviewers saying they'd recommend us. Our customers cut time-to-access by 98%, slash IT tickets by 72%, and eliminate excess privilege at scale.
- 🏆 A culture worth joining. Three years running on Forbes' Top 100 Best Startup Employers in America (2024, 2025, 2026) — measured on culture, retention, growth, and job creation. That's our Alchemists, not our marketing. See what we live by here.
We’re looking for a AI Agent Engineer to join the team. You'll build and own core AI features, in addition to helping to ensure the health of our engineering systems. You will work across the stack, focusing on areas you are most excited about and that bring value to customers. Beyond your technical work, you will gain leadership opportunities early on as we grow our engineering team. You'll be involved in scaling the product, the team, and the entire company. 🚀
✨ Your Responsibilities
- Lead the development of agent pipelines: design modular SDK components, drive production rigor, and support the growth of junior engineers.
- Architect composable agent SDKs with built-in safety and robust fallback strategies.
- Design tracing tools and alert dashboards to ensure agent performance and quality.
- Own the agent lifecycle—from chaining and testing to CI/CD and production rollout.
- Collaborate closely with security and operations teams to ensure agent governance and auditability.
- Mentor and uplevel teammates on best practices in observability and resilience.
- Solve challenging technical problems across the stack to develop critical customer-facing features; includes the frontend (React, Typescript), communication layer (GraphQL, Apollo), and backend (Python, Flask, sqlalchemy).
🙌 What We Value
We’re looking for engineers who want to shape the next generation of intelligent agents—people who care deeply about building reliable, modular systems and elevating those around them. If you’re energized by architecting robust agent SDKs, creating tools that ensure safety and observability, and mentoring others, you’ll thrive at Lumos.
- You’ve built and deployed AI-driven workflows — such as tool-calling systems, retrieval-augmented generation (RAG) pipelines, or autonomous agentic orchestration using frameworks like LangChain, LangGraph.
- Strong software engineering experience with 5+ years of building and scaling end-to-end production systems.
- Strong knowledge of API design, system performance, and software architecture.
- Proficiency in modern programming languages such as Go, TypeScript, or Python, and familiarity with frameworks like React.
- Familiarity with identity and access management systems, such as SCIM, OAuth2, SAML, or integrating with IDPs and HRIS tools.
