Senior Real-Time C++ Distributed Simulation Engineer

Engg; Seattle (WA); On-site; USD 150,000 - 210,000; Full time

Job summary

Anduril Industries is seeking a Senior Software Engineer to join the Software Integration Environment team in Seattle. You will design and implement the simulation layer for the SIE platform, building C++ services that let diverse simulators share a single world with a common clock and entity namespace.

You will own end-to-end development from design to production, work with Go and TypeScript components, and help onboard other teams.

Qualifications

• 7+ years of professional software engineering experience.
• Deep, current production experience in modern C++ (C++17 or newer).
• Experience building networked, concurrent, or real-time systems in C++.
• Strong systems fundamentals: memory layout and allocation behavior, cache effects, sockets and UDP/TCP, serialization, and Linux.
• Demonstrated ability to profile and optimize a real system, and to reason about latency and throughput with numbers.
• Experience owning an ambiguous, cross-cutting project end-to-end and driving it to production.
• Experience working directly with the engineering teams who consume what you build — integrating them, unblocking them, and taking their feedback into the next version.
• Comfortable working in at least one other language alongside C++ — the surrounding platform is Go and TypeScript, and you will touch both.
• Strong written and verbal communication — you can write a design document that a skeptical reader can evaluate.
• Computer Science degree or equivalent industry experience.
• Eligible to obtain and maintain an active U.S. Secret security clearance.

Responsibilities

• Design and build the C++ services that federate independent simulators into a single simulated world — time management, entity registry and ownership, join/resign lifecycle, and state distribution
• Own the wire layer: protocol encoding and decoding, multicast and unicast transport, and the interoperability work required to make simulators talk to each other
• Make simulation runs deterministic and reproducible — time control, replay, and instrumentation that explains a divergence
• Build and generalize the scenario and laydown authoring tooling used to describe runs
• Build content and resource catalogs to save, tag, search, and reuse environment and scenario definitions
• Chase down performance: profile hot paths, control allocation and copying, and hold latency and throughput budgets under load with hundreds to thousands of entities
• Integrate with the Go services that provision compute, the gRPC/protobuf APIs, and the web UI
• Set the technical direction for this area, write design docs, and mentor the team as it grows
• Partner with Anduril business lines onboarding onto the platform — onboard simulators, models, and test workflows
• Reduce onboarding cost by documenting integrations and providing SDKs for self-serve use
• Work with internal teams and external customers to turn feedback into shipped capability
