Qualifications

• 0+ years of experience not stated in the ad.

Responsibilities

• Design and implement core components of our identity sync pipeline, including the ingestion, transform, validation, and install stages that turn raw identity data into a trusted foundation other products depend on.
• Build and extend our sync observability framework, enabling reusable patterns for monitoring, alerting, failure detection, and operational tooling across a high-volume, integration-driven pipeline.
• Work across teams to close monitoring and reliability gaps, catching sync failures and stalled jobs before they reach customers.
• Contribute to a strong operational foundation by building the safety nets, circuit breakers, and self-healing reconciliation that keep identity data trustworthy at scale.
• Drive key technical decisions and lead by example, through architecture reviews, mentoring, and pairing with other engineers on complex sync and correctness problems.
• Champion resilience, observability, and scalability in every layer of the identity sync stack.

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.

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.
