Software Engineer, Developer Infrastructure - Build Systems (Los Angeles)

About NominalNominal is building the connected test and operations platform powering the world's most advanced hardware systems, from spacecraft and autonomous vehicles to next-generation defense programs. Our platform gives hardware engineering teams a single place to ingest data, analyze performance, automate test execution, and collaborate across every phase of development, so they can move faster without sacrificing safety or precision. We're a fast-moving team that owns problems end-to-end, works across disciplines, and thrives at the intersection of hardware and software.We serve top-tier commercial and defense customers, from autonomy leaders like Anduril and Shield AI to next-generation aerospace teams like Hermeus and REGENT, and performance engineering teams like Pratt Miller Motorsports, alongside mission partners within the U.S. Navy and U.S. Air Force on programs where failure isn’t an option. We’re backed by Sequoia, General Catalyst, Founders Fund, Lux Capital, and Lightspeed. Our team draws from SpaceX, Palantir, Anduril, Applied Intuition, and other leading companies, united by a common mission: giving hardware engineers the tools to build the future with speed, safety, and confidence.We're looking for a Software Engineer to join Nominal's Developer Infrastructure team. You'll develop the build infrastructure that every engineer at Nominal depends on, with an eye towards continuously optimizing the build performance and local devx to better scale with our growing engineering organization. You'll also own the developer infrastructure that keeps engineering velocity and release quality high, such as observability, pre-merge validation, and more. As one of the founding engineers on the team, you'll shape the tooling, developer experience, and engineering practices that every engineer at Nominal relies on from day oneð About The RoleBuild, optimize, and maintain Nominal's large-scale build systems, with Bazel as the highest priority.Improve CI/CD pipeline performance, release automation, and release reliability.Own developer infrastructure that enables engineering velocity as our monorepo and engineering organization scale.Build and maintain observability, telemetry, logging, and metrics infrastructure using tools like Datadog, Grafana, and OpenTelemetry.Partner closely with product engineering teams to remove developer friction and improve day-to-day engineering productivity.
