Anduril Industries • Irvine, California, United States
Role & seniority: Senior Software Engineer responsible for architecting, building, and owning HITL/SITL testing infrastructure for Tower software.
Stack/tools: C++ (production-quality, 4+ years); high-fidelity simulation/emulation (Unreal Engine for cameras); networking (TCP/IP, UDP), hardware interfacing (Ethernet, CAN); CI/CD (Jenkins, GitLab CI); containerization (Docker); scripting (Python); data formats (Protobuf/FlatBuffers).
Architect, build, and maintain the physical HITL server rack and networking to enable parallel automated testing across hardware generations.
Develop/integrate high-fidelity simulation for core components (cameras via Unreal, Radar, GPS, IMU) for end-to-end system testing.
Integrate simulation with CI pipeline; create automated tests for system health, performance, track generation, and manufacturing validation; deliver a self-service framework with documentation.
4+ years producing production-quality C++ code.
Experience designing/building complex test infrastructure, SITL/HITL, or embedded test harnesses.
Expertise in networking (TCP/UDP) and hardware interfacing (Ethernet, CAN); ability to debug multi-device test environments.
Ability to own a software system end-to-end (design, deployment, maintenance).
Strong engineering background; eligible for active U.S. Secret clearance.
Unreal Engine-based sensor data generation experience.
CI
We are seeking a dedicated Senior Software Engineer to architect, build, and own our Hardware-in-the-Loop (HITL) and Software-in-the-Loop (SITL) testing infrastructure. This is a high-impact role critical for validating our Tower software from development through manufacturing and deployment. You will have the autonomy to design our end-to-end simulation strategy from the ground up, creating a foundational framework that directly accelerates development and improves reliability for the Sentry Tower and partner organizations like Air Defense and Counter Intrusion. If you are driven by a “Whatever It Takes” mindset and want to build the systems that prove our systems work, then this role is for you.

ABOUT THE TEAM The Sentry Tower Software team is responsible for developing robotic systems that provide force protection capabilities, monitoring the perimeter of secure areas, land or sea, for approaching people, vehicles, and vessels. We live in a world where security officers are increasingly overwhelmed by sensor data feeds. Our products leverage advanced sensor fusion and autonomy to seamlessly render activity in the environment to Lattice's common operating picture. To achieve this at scale and with extreme reliability, we are building a world-class simulation and test infrastructure to validate our systems at every stage of development.
WHAT YOU'LL DO Architect, build, and maintain the physical HITL server rack, including networking infrastructure, to enable parallel, automated testing across multiple hardware generations. Develop and integrate high-fidelity simulation and emulation for core components, including cameras (via Unreal Engine), Radar, GPS, and IMU, to enable true end-to-end system testing. Own the integration of the simulation environment with our Continuous Integration (CI) pipeline, creating automated tests for system health, performance, track generation, and manufacturing validation. Create a robust, self-service simulation framework with clear documentation that empowers other engineers and teams to rapidly test their features and system integrations. Write clean, high-performance C++ code to build out simulation services, test harnesses, and infrastructure components that form the backbone of our verification strategy.
REQUIRED QUALIFICATIONS 4+ years of professional experience writing production-quality C++. Proven experience designing and building complex test infrastructure, simulation environments (SITL/HITL), or embedded test harnesses. Expertise in networking principles (TCP/IP, UDP) and hardware interfacing (Ethernet, CAN), with experience debugging complex, multi-device test environments. Demonstrated ability to own a complex software system end-to-end, from architectural design to deployment and maintenance. Strong engineering background from industry or school, ideally in areas/fields such as Computer Science, Software Engineering, Mathematics, or Physics. Must be eligible to obtain and maintain an active U.S. Secret security clearance.
PREFERRED QUALIFICATIONS Experience with simulation platforms, particularly Unreal Engine, for sensor data generation (camera, lidar, radar). Experience with CI/CD systems (e.g., Jenkins, GitLab CI) and containerization technologies (e.g., Docker). Proficiency in Python for scripting, tooling, and test automation. Familiarity with data serialization formats like Protobuf or FlatBuffers. Experience with robotics, controls, or mechatronic systems.
