Responsibilities
Design and implement hard real-time components for data acquisition, control, and simulation using C++ and/or Rust
Develop deterministic communication layers for CAN, EtherCAT, serial, and MIL-STD-1553 or similar field buses
Architect the core HIL runtime, including task schedulers, timing controllers, and synchronization primitives
Integrate with embedded targets, flight computers, and sensor networks to validate autonomy and control software
Collaborate with our infrastructure and visualization teams to connect real-time execution with distributed telemetry, playback, and analysis pipelines
Profile, benchmark, and harden low-latency systems to meet microsecond-level timing guarantees
Establish testing and verification standards for real-time correctness and timing determinism across the platform
Qualification
Required
4+ years of systems-level or embedded software development in C++ (C++17 or newer) or Rust, with a deep understanding of real-time constraints and deterministic scheduling
Experience with RTOSs such as QNX, RTEMS, FreeRTOS, VxWorks, or Linux PREEMPT-RT
Background in HIL or SIL testing, real-time control loops, or simulation frameworks for aerospace, automotive, or robotics
Strong grasp of hardware interfaces, timing jitter, interrupt handling, and low-level I/O
Familiarity with signal acquisition, control systems, and sensor fusion concepts
Ability to debug at multiple layers — from driver-level to distributed telemetry — and to reason clearly about timing and causality
