New York, United States
Full-time
Onsite
Mid Level
$160K/yr - $230K/yrUMATR is seeking a Systems Software Engineer to build and maintain the core real-time infrastructure for a high-performance test automation and simulation platform. The role involves designing and implementing hard real-time components and developing deterministic communication layers, ensuring low latency and correctness across platforms.
Hiring Manager
Jude Rushford
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, MIL-STD-1553 , or similar field buses
Architect core HIL runtime systems 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 infrastructure and visualization teams to bridge real-time execution with telemetry, playback, and analysis tools
Profile, benchmark, and harden low-latency systems to meet microsecond-level timing guarantees
Establish testing and verification standards to ensure deterministic timing and correctness across platforms
