Job description

Imagine having an enterprise-grade AppStore at work — one that ensures you can easily search, request, and gain access to any app you need, precisely when you need it. No more long waiting times with outstanding IT requests. Lumos is solving the app and access management challenges for organizations of all sizes through a unified platform. Our fast-growing startup is pioneering the way to untangle the complex web of app and access management by building the critical infrastructure that defines relationships between app, identities and data.

Why Lumos?

• Jump on a Rocketship: Since launching out of stealth mode just over 2 years ago, our team has grown from 20 to ~100 people and our customer base has 10x’ed with companies like GitHub, MongoDB and Major League Baseball!
• Build with Renowned Investor Backing: Andreessen Horowitz (a16z) backed us since the beginning and we've raised over $65m from Scale, Neo, Greg Brockman (President at OpenAI), Phil Venables (CISO at Google), and others.
• Thrive in a Unique Culture: You’ll join an early-stage company where you have actual influence on the trajectory of the company. We deeply care about our people and the philosophy we live by - check outour values here.

We’re looking for aStaff Software Engineer to help drive the evolution of our Integrations Platform—the core foundation that enables Lumos to connect with the tools and systems our customers rely on. From cloud identity providers and HR systems to on-prem applications and ITSMs, your work will power the seamless, secure, and scalable flow of data and permissions across enterprise environments.

You’ll play a key role in designing and building robust connector frameworks, integration infrastructure, and developer-facing tools that deliver top-tier reliability and a great developer experience. You’ll collaborate with platform, product, and infrastructure teams to scale our platform’s capabilities while shaping how developers—both inside and outside Lumos—build on top of it.

We’re a startup that values ownership, curiosity, and trust—and we’re looking for teammates who thrive on solving hard systems problems with empathy and creativity.

Your Responsibilities

• Design and implement core components of our Integrations Platform, including APIs, event-driven systems, and connector orchestration layers that support a wide range of cloud and on-prem integrations.
• Build and extend our integration framework, enabling reusable patterns for authentication, job retries, error handling, observability, and developer onboarding.
• Work across teams to deliver high-performance, secure, and maintainable integrations with external systems such as Okta, Workday, Azure AD, ServiceNow, and more.
• Contribute to a delightful developer experience by building SDKs, CLI tools, and documentation that accelerate integration development both internally and externally.
• Drive key technical decisions and lead by example—through architecture reviews, mentoring, and pairing with other engineers on complex problems.
• Champion resilience, observability, and scalability in every layer of the integrations stack.

What We Value

We're looking for engineers who think like platform builders and care deeply about the craft and clarity of their work. If you’re energized by designing reusable systems and creating tools that unlock others, you’ll thrive here.

• Strong experience as a backend or platform engineer, with 5+ years of experience building scalable services, APIs, or integrations.
• Experience working with enterprise integration patterns—including webhooks, event queues, third-party APIs, and hybrid (cloud/on-prem) environments.
• Proficiency in one or more modern backend languages (e.g., Python, Go, TypeScript) and strong knowledge of API design, system performance, and software architecture.
• Familiarity with identity and access management systems, such as SCIM, OAuth2, SAML, or integrating with IDPs and HRIS tools.
• A thoughtful approach to developer experience, both in the systems you build and how you communicate technical decisions.
• A bias toward action, a high bar for quality, and a track record of shipping platform features that scale well and are loved by other developers.
