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

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

Preferred

Experience with LabVIEW, NI TestStand, PXI/DAQ systems, or integration with external test equipment
Knowledge of time-synchronized networking (PTP/NTP), DDS, or real-time middleware (ROS 2, RTI Connext)
