Job summary

Nominal is hiring a Software Engineer, Runtime Infrastructure to build the foundation that all Nominal services run on. You’ll shape how services are observed, how they communicate, and how they perform under load and failure.

You’ll work with backend and full-stack engineers, balancing speed with reliability, and you’ll contribute to tooling both in-house and in open source projects our teams rely on. You’ll collaborate closely with product, frontend, platform, and deployment teams to define

Qualifications

• 3+ years of experience as a backend or full stack engineer, building and running production systems where performance, reliability, and operational simplicity matter.
• Strong experience in at least one of Rust, Java, or TypeScript, with an emphasis on correctness, clarity, and long-lived systems.
• Experience designing libraries, frameworks, or APIs that other engineers build on: hiding complexity behind simple interfaces, sensible defaults, and changing things without breaking the people who depend on you.
• Hands-on experience with observability tools such as OpenTelemetry, Prometheus, or Datadog, including metrics, traces, and alerts that engineers actually rely on.
• A solid understanding of concurrency, async runtimes, networking, and how distributed systems behave under load and failure.
• A systems mindset. You like working out how a system should behave, and how it will fail, before you build it.
• Excellent communication skills, and the ability to explain technical tradeoffs clearly to the engineers who depend on your work.
• A bias toward ownership: you design it, build it, ship it, and run it.

Responsibilities

• Build the foundation other engineers stand on by creating service frameworks and shared libraries for reliability, observability, and secure defaults.
• Find where time and memory go by investigating concurrency, memory, and latency across services and turning findings into fixes and usable tools.
• Treat other engineers as customers and collaborate with teams to understand their needs, shipping code that is easy to operate and debug.
• Work across product, frontend, platform, and deployment teams to shape requirements and make informed tradeoffs that affect the whole stack.
• Potentially contribute to open source projects we depend on, enhancing tooling used across Nominal and customer systems.

Job description

About Nominal

Engineers today are building some of the most ambitious machines humanity has ever seen. They should have AI that’s purpose-built for them.

Nominal is building the Hardware Intelligence Platform that gives engineers increased visibility into complex physical systems, helps them make better decisions, and ultimately gets their products into the real world faster. It brings together the systems, data, intelligence, and applications hardware engineering requires to meet the AI moment. Hardware engineering teams use Nominal to simulate, test, manufacture, and operate the physical systems that keep the world moving, from spacecraft and autonomous vehicles to next-generation energy systems and robotics.

Our customers span aerospace, defense, manufacturing, transportation, energy, and robotics. They include Anduril, Shield AI, Wisk Aero, Pratt Miller Motorsports, Antares, and Shinkei Systems, amongst others, alongside programs within the U.S. Air Force and Navy. Our team draws from SpaceX, Palantir, Anduril, Applied Intuition, Tesla, 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 a fast-moving team that owns problems end-to-end, works across disciplines, and thrives at the intersection of hardware and software.

Some of the world’s leading technology investors, including Sequoia, Lightspeed, Founders Fund, General Catalyst, Lux Capital, and Insight Partners, are backing Nominal’s ambition to change how machines are built and operated. We’re looking for engineers who want to take on hard problems and help make a new generation of world-changing hardware possible.

Join Nominal as a Software Engineer, Runtime Infrastructure

Nominal runs mission-critical software wherever our customers need it: in our cloud, in theirs, and on disconnected networks for defense programs. An engineer might be watching a vehicle in real time or working through terabytes of post-test data. Either way, every layer between the hardware and the chart on their screen has to be fast and correct. Our customers expect a lot from us on reliability, security, and compliance. Runtime Infrastructure builds the libraries, services, and standards that let every Nominal team meet that bar by default.

As a Software Engineer on Runtime Infrastructure, you'll build the foundation the rest of engineering builds on. That covers how our services and applications are observed, how they record who did what, how they talk to each other, and how they behave under load and failure. Your main users are other Nominal engineers. If you do this well, they ship faster, catch problems sooner, and meet our customers' standards without having to think about it. Through them, your work reaches the aerospace, defense, and autonomy teams who use Nominal for mission-critical testing.

We're hiring both backend and full stack engineers for this team. You'll build services, libraries, and APIs that have to be correct, fast, and long-lived. You'll care about architecture across the whole stack: how our web applications are structured, how they talk to the backend, and how they behave in production. You'll have a lot of autonomy and work closely with product, frontend, platform, and deployment engineers. You'll help shape the requirements yourself, with input from fellow engineers and our customers, and make the tradeoffs that decide how our systems are built. You'll also be able to contribute to the open source projects we depend on.

About the role

Build the foundation other engineers stand on

Build the service frameworks and shared libraries that every Nominal service starts from: configuration, health checks, graceful shutdown, resource limits, resilience, secure defaults, and the conventions for how services define their APIs and talk to each other. The goal is that a new service is reliable, observable, and compliant from its first commit. You'll measure success by how quickly other engineers can ship, debug, and operate their own services.

Find where the time and memory go

Investigate concurrency, memory, and latency problems across our services. You'll build runtime metrics, profiling, and load testing, then turn what you find into fixes, and into tools other engineers can use on their own.

Success in this role comes from treating other engineers as your customers. You'll spend as much time understanding how teams build, run, and debug software as you will writing code.

We'd love to hear from you if you have

• 3+ years of experience as a backend or full stack engineer, building and running production systems where performance, reliability, and operational simplicity matter.
• Strong experience in at least one of Rust, Java, or TypeScript, with an emphasis on correctness, clarity, and long-lived systems. You don't need all three, but you should be excited to work across them.
• Experience designing libraries, frameworks, or APIs that other engineers build on: hiding complexity behind simple interfaces, sensible defaults, and changing things without breaking the people who depend on you.
• Hands-on experience with observability tools such as OpenTelemetry, Prometheus, or Datadog, including metrics, traces, and alerts that engineers actually rely on.
• A solid understanding of concurrency, async runtimes, networking, and how distributed systems behave under load and failure.
