Lumos is making it a joy for companies to manage their apps and identities ✨. By integrating usage, spend, compliance, and access data, we provide a level of clarity and insight previously unimaginable. To deliver a best-in-class product, Lumos depends on state-of-the-art data pipelines that power our analytics and AI-driven solutions.

We’re looking for a Staff or Principal Software Engineer to lead the design architecture of our Entitlements and Access Management Integrations Platform. This is a foundational role—one that directly shapes how enterprises manage who gets access to what, and why, across their software ecosystem. You'll architect the systems that power automated provisioning, fine-grained entitlements, and identity-aware integrations that customers trust to enforce the right access in the right context.

As part of a small and high-impact team, you’ll operate with autonomy, lean into ambiguity, and solve for scale. You’ll partner with product and engineering leadership to design platform capabilities that not only meet compliance and security requirements, but also delight developers and customers with their clarity and reliability.

We’re a startup that believes in owning the outcome, staying curious, and building with trust—both in the software we ship and the people we work with.
