Software Engineer, Data Engineering

Lumos; New York (NY); On-site; USD 120,000 - 160,000; Full time

Job summary

Lumos is the industry's first Autonomous Identity Platform — software that doesn't just surface access risk, but acts on it. We power a self-service AppStore and connect apps, identities, and data for major customers.

At the center is Albus, our AI agent for identity, mining roles, approving access, and catching the drift humans miss. As a Software Engineer on our Data Engineering team, you will design and ship the shared primitives product teams build identity features on.

Responsibilities

• Design and implement core components of our identity data platform, including APIs, service layers, and interfaces that abstract raw identity data into shared primitives other products build on.
• Build and extend our data interface framework, enabling reusable patterns for contract design, versioning, and observability across producer and consumer teams.
• Work across teams to migrate product surfaces off direct integration or database reads and onto well-defined, product-grade APIs.
• Contribute to a world-class data infrastructure by building the primitives, Access Graph APIs, the Unified Entitlements Data API, and similar, that let engineering, product, and AI teams access high-quality identity data seamlessly.
• Drive key technical decisions and lead by example, through architecture reviews, mentoring, and pairing with other engineers on complex data-interface problems.
• Champion resilience, observability, and scalability in every layer of the identity data platform.

Job description

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.

Overall Description

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.

At the heart of our products is our identity data platform, the systems that ingest identity data from hundreds of third-party integrations and turn it into the trusted, insight-rich primitives that power every Lumos product.

As a Software Engineer on our Data Engineering team, you will design and ship the shared primitives product teams build identity features on.

You'll lead projects like defining and shipping an integration‑agnostic Access Graph API. Today Identity Intelligence consumes EntraID's access graph through a direct integration call, capping insights to a single integration, and your work will let Identity Intelligence and future products generate insights across every access‑graph‑enabled integration as it comes online.

We're a startup that values ownership, curiosity, and trust, and we're looking for engineers who love building platform infrastructure that enables teams to move faster while improving resilience and visibility.
