Enterprise Customer Success Manager

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.

As a Lumos Enterprise Customer Success Manager, you’ll be the trusted partner to our largest and most strategic customers. You’ll guide them through onboarding, ensure adoption and expansion, and influence both customer outcomes and our product roadmap.
