Software Engineer, Identity Platform - Lumos

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 Identity Platform team, you will drive the evolution of our identity data backbone, the systems every Lumos product depends on. You'll lead projects like our Sync Observability MVP work, closing the internal monitoring gaps in our Dagster-orchestrated identity sync pipeline (FIS) so the team catches failures before customers report them, building robust, scalable, and reliable platform software that operators can trust.

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.

Your 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.

What We Value

While specific qualifications are less important than your drive and potential, the following experiences will set you up for success in this role:

• Strong experience as a backend or platform engineer, building production data pipelines that other teams depend on using Dagster, Airflow, or comparable orchestration, with sharp instincts for correctness, idempotency, retries, and operational visibility in systems that hundreds of third-party integrations flow through.
• Proficiency in one or more modern backend languages (Python, Go, or TypeScript), with a focus on clean API design, testability, and observability.
• A strong instinct for data correctness, SLOs, and shift-left detection in systems where downstream products act on the output, catching a partial failure at 20% beats a customer report at 100%.
• Experience with circuit breakers, self-healing systems, and operational rigor in business-critical, high-volume pipelines.
• Familiarity with identity and access governance (IGA) data (identities, accounts, entitlements, group memberships) and how its correctness, freshness, and traceability shape downstream governance outcomes at scale.
