Senior Software Engineer, Distributed Simulation (C++) at Anduril | LAYIQ

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 built by different teams and vendors talk to each other
Make simulation runs deterministic and reproducible enough that a result is evidence, not a demo — including time control, replay, and the instrumentation that explains a divergence
Build and generalize the scenario and laydown authoring tooling that engineers and operators use to describe what they want to run
Build the content and resource catalogs that let users save, tag, search, and reuse environment and scenario definitions instead of rebuilding them each time
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 rest of the platform — the Go services that provision and schedule compute, the gRPC/protobuf APIs that expose it, and the web UI the team owns
Set the technical direction for this area, write the design docs that make it reviewable, and raise the bar through code review and mentorship as the team grows
Partner with Anduril business lines when they onboard onto the platform — work alongside their engineers to get their simulators, models, and test workflows integrated, and stay with them until it works in their hands and not just yours
Reduce the cost of that onboarding over time by turning the integration work you do by hand into documentation, reference integrations, and SDKs, so the next team can self-serve
Work directly with the internal teams and external customers who need this, and convert what they tell you into shipped capability
REQUIRED QUALIFICATIONS
7+ years of professional software engineering experience
Deep, current production experience in modern C++ (C++17 or newer) — you are fluent in ownership and lifetime, move semantics, templates, and the standard library
Experience building networked, concurrent, or real-time systems in C++, including multithreading, synchronization, and the failure modes that come with them
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 rather than intuition
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
