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 raised over $65M from a16z, Scale, Neo, and other top-tier investors, and has grown from 20 to ~130 employees since launching from stealth in April 2022.
As a Software Engineer on the Identity Platform team, you will drive the evolution of Lumos's identity data backbone—the foundational systems that every product depends on. You'll own high-impact projects like building Sync Observability MVP work, closing internal monitoring gaps in the Dagster-orchestrated identity sync pipeline (FIS) so the team catches failures before customers report them.
Key responsibilities include:
- Design and implement core components of the identity sync pipeline, including ingestion, transform, validation, and install stages that turn raw identity data into a trusted foundation.
- Build and extend the 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 operational foundation by building 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.
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 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.
- Strong instinct for data correctness, SLOs, and shift-left detection in systems where downstream products act on the output.
- 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.
