Lumos is an Autonomous Identity Platform that surfaces and acts on access risk, serving customers like GitHub, MongoDB, Mars, Pinterest, Anduril, Intercom, Roku, and Netskope. The company has grown from 20 to ~130 employees since launching from stealth in April 2022, raised over $65M from a16z, Scale, Neo, and other top-tier investors, and is named a Strong Performer in the 2026 Gartner Voice of the Customer for IGA with 4.7/5 rating.
As a Software Engineer on the Data Engineering team, you will design and ship the shared primitives that product teams build identity features on. You'll lead projects like defining and shipping an integration-agnostic Access Graph API, enabling Identity Intelligence and future products to generate insights across every access-graph-enabled integration. Your work will migrate product surfaces off direct integration or database reads onto well-defined, product-grade APIs.
Key responsibilities include:
- Design and implement core components of the identity data platform, including APIs, service layers, and interfaces that abstract raw identity data into shared primitives.
- Build and extend the data interface framework, enabling reusable patterns for contract design, versioning, and observability across producer and consumer teams.
- Work across teams to migrate product surfaces onto well-defined APIs.
- Contribute to world-class data infrastructure by building primitives like Access Graph APIs and Unified Entitlements Data API.
- Drive key technical decisions and lead by example through architecture reviews, mentoring, and pairing with other engineers.
- Champion resilience, observability, and scalability in every layer of the identity data platform.
The role is ideal for engineers who love building platform infrastructure that enables teams to move faster while improving resilience and visibility. Lumos values ownership, curiosity, and trust.
REQUIREMENTS:
- Strong experience as a backend or platform engineer, building service layers in front of a transactional database (MySQL/Postgres) that abstract storage from internal consumers, or comparable ingestion/sync pipeline experience with Dagster, Airflow, or similar.
- Proficiency in one or more modern backend languages (Python, Go, or TypeScript), with a focus on clean API design, testability, and observability.
- Experience designing service or API interfaces over a transactional datastore, defining contracts that let producers and consumers evolve independently; gRPC or comparable is a plus.
- Strong instinct for data correctness, observability, and SLOs in systems where downstream products take action on the output.
- Familiarity with identity and access governance (IGA) data (identities, accounts, entitlements, group memberships, non-human identities) and how its correctness, freshness, and traceability shape downstream governance outcomes at scale.
