Software Engineer, AI Agent Governance

About the role

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.

Your Responsibilities

• Ship backend features end to end, from a rough customer ask to running in production, often in days rather than weeks.
• You don’t just ship to a spec, rather you ensure value is delivered to customers. You are a valued member of the oncall rotation.
• Build the testing systems and harnesses that let agents ship changes safely.
• Work directly with customers when issues arise.
• You utilize agents heavily in your day to day work, but you have a deep understanding of the system architecture and can whiteboard it for a coworker at a moment’s notice.

What We’re Looking For

• 1+ years of professional software engineering experience, or an equivalent track record of shipping real products
• Strong backend fundamentals. You've built APIs, databases and services that run in production. Our stack is Python, Postgres, OpenSearch and gRPC on AWS.
• You're AI native. You understand how agents work under the hood: tool calls, MCP servers, hooks and context.
• You're comfortable with ambiguity. You've worked somewhere small and fast, you start before the spec is finished, and you change direction when customers tell you something new.
• You take ownership. This is a high-intensity role on a product that's still finding product market fit. We work hard and move fast, and we want people who are excited by that.
• Nice to have: experience with endpoint or client software (MDM, software that runs on laptops), a security or identity background.

What We Value

• We also care about whether you would be a good fit for Lumos based on the values and characteristics that define how we achieve outcomes, not just your resume.
• Thank you for considering Lumos, we hope to hear from you!

Pay Range

• $133,500 - $150,000 plus equity + benefits (Note that this range is a good faith estimate of likely pay for this role; upon hire, the pay may differ due to skill and/or level of experience.)

Benefits and Perks

• Remote-first culture - Work from anywhere within ±4 hours of Pacific Time.
• Medical, dental & vision insurance - 100% of premiums covered for employees, 60% for dependents. HSA and FSA available with employer contribution. International benefits align with local standards.
• Mental health support - Access to mental health resources and support.
• Monthly wellness stipend - A monthly stipend for gym memberships, fitness apps, and whatever helps you recharge.
• Life & disability insurance - Life insurance, short-term disability, and long-term disability coverage available.
• Flexible PTO - Flexible time off with a minimum annual requirement, because rest is part of doing your best work.
• Parental leave - Up to 16 weeks of paid parental leave for expecting parents.
• $1,000 annual learning stipend - An annual budget for courses, books, conferences, and certifications.
• Company & team offsites - Company and team bonding trips throughout the year, fully covered by Lumos.
• 401(k) with matching - Employer 401(k) matching to help you save for the future.
