Software Engineer, NHI Platform

Lumos builds an identity data platform that connects applications, identities, and data for its products. The Software Engineer on the NHI Platform team will build and operate the non-human identity data backbone, transforming third-party identity inputs into reliable data foundations for Lumos products.

Responsibilities:

• Design, develop, and operate systems that transform high volumes of identity data from third-party integrations to product consumers with correctness, freshness, and operational rigor
• Contribute to the technical vision for a world-class data infrastructure that empowers engineering, product, and AI teams, enabling seamless access to high-quality data
• Establish SLOs, observability, and operational tooling that catch and remediate failures in identity data systems before they reach customers
• Promote and implement software engineering best practices for building scalable, reliable, and secure data-centric applications. Elevate the principles of software engineering within the data domain

Requirements:

• 1+ years of professional backend or platform engineering experience building production systems other teams depend on, such as ingestion, sync, or event-driven pipelines
• Strong backend fundamentals. You've built APIs (REST or gRPC) and services backed by relational databases like Postgres or MySQL, and you've evolved schemas on live tables
• You care about correctness. You think about idempotency, ordering, retries vs. permanent failures, and dead-letter handling, because downstream products take action on the data you produce
• You operate what you ship. You've deployed containerized services to AWS, GCP or Azure, debugged from metrics, traces and logs, and been part of an on-call rotation
• You're excited to build from the ground up. This is a greenfield team, and the systems you build become the foundation every other Lumos product runs on
• Kafka, Temporal or change data capture (Debezium), Terraform, and familiarity with identity data like accounts, entitlements, service accounts and API keys
