Job summary

Heaviside Industries is seeking a highly experienced engineer to architect and ship real-time DSP pipelines for multi-domain RF systems. The role focuses on low-latency angle estimation, time-of-arrival processing, and detector-style calibration across multiple receivers, in support of operating in GPS-denied environments.

You will drive edge compute integration and field verification with production-ready silicon.

Qualifications

• MS or PhD in Electrical Engineering or related field
• 5+ years building real-time DSP on hardware in UAVs or radar systems
• Hands-on experience taking phase-coherent multi-channel systems from bench to flying/fielded
• Production-grade experience in fire-control radar, RWR, ESM or RF detection
• Deep knowledge of sum-and-difference angle estimation and calibration discipline
• Real-time tracking filters (alpha-beta, Kalman, IMM) with airframe-pose fusion
• DSP / signal processing with Pulse-Doppler
• Proficiency in GPU-accelerated Python (NumPy/CuPy/CUDA) and C/C++ for RT targets
• Experience with industrial/tactical IMUs and high-stability references (OCXO, CSAC, rubidium)
• Able to obtain/maintain a US Secret security clearance

Responsibilities

• Architect and ship real-time DSP pipelines on multi-channel RF systems
• Implement low-latency bearing-angle estimation from synchronized data
• Build closed-loop pipeline: time-of-arrival, pulse-train association, and filters
• Calibrate channel stack across receivers in real-time
• Add false-alarm-rate management and interference rejection
• Drive sub-millisecond end-to-end latency to production silicon
• Specify and integrate RF systems, timing-reference, and edge compute
• Conduct bench bring-up, anechoic-chamber, and captive-carry verification campaigns

Job description

ABOUT HEAVISIDE INDUSTRIES

Heaviside Industries builds multi-domain autonomous precision munitions for U.S. and allied special operations and conventional forces. While modern warfare has rapidly evolved with the proliferation of unmanned systems, hyper-precise munitions in contested environments are the future of the battlefield. Economical precision strike capabilities are critical to U.S. and allied war efforts, enabling successful defeat of enemy military assets and infrastructure. Heaviside builds precision munitions designed to operate in GPS-denied and spectrum-jammed battlefields - where traditional systems degrade or fail - without inflated prices or sacrifice to performance.

All engineering and manufacturing is conducted in-house in Heaviside's Los Angeles, CA headquarters and Oslo, Norway office.

Heaviside is backed by Felicis, Hedosophia, Interlagos, Friends & Family Capital, Menlo Ventures, Flume Ventures, Cantos, and others.

WHAT YOU WILL DO

• Architect and ship real-time DSP pipelines on multi-channel RF systems (multi-channels, hardware-locked sampling, OCXO reference)
• Implement low-latency, single-snapshot bearing-angle estimation from synchronized multi-channel data - sum-and-difference channel processing and Σ/Δ ratio calibration
• Build the closed-loop pipeline: time-of-arrival measurement, pulse-train association, and filters (alpha-beta, Kalman, EKF, IMM) fused with airframe pose
• Build the channel-calibration stack - phase, amplitude, and alignment across all receivers, applied in a real-time pipeline
• Add false-alarm-rate management, sidelobe blanking, and interference-rejection techniques for contested-spectrum operation
• Drive deterministic, sub-millisecond end-to-end pipeline latency that survives transition from prototype to production silicon (FPGA / RFSoC)
• Specify, integrate, and bring up the RF systems, timing-reference, and edge-compute stack for new programs
• Run bench bring up, anechoic-chamber, and captive-carry verification campaigns to closure

WHAT WE ARE LOOKING FOR

• MS or PhD in Electrical Engineering, ECE, Applied Physics, or related field - or equivalent shipped-product experience
• 5+ years building real-time DSP systems that ran on actual hardware in actual missions on unmanned aerial systems or ground radar systems
• Hands-on experience taking phase-coherent multi-channel systems from bench to flying or fielded system
• Production-grade work on at least one of: fire-control radar processing, RWR, ESM, SIGINT, or other RF detection systems
• Deep working knowledge of sum-and-difference / comparator-based angle estimation, and the calibration discipline that makes them deliver precision
• Production implementation of real-time tracking filters - alpha-beta, Kalman, IMM - with airframe-pose fusion and dropout handling
• Pulse-Doppler signal processing experience
• Comfortable in BOTH GPU-accelerated Python (NumPy / CuPy / CUDA) for prototype and edge-compute work AND C/C++ for hard-real-time targets; understands when each is appropriate
• Experience with industrial- or tactical-grade IMUs and high-stability frequency references (OCXO, CSAC, rubidium)
• Practitioner with NanoVNA and calibrated lab VNA; can read multi-port S-parameters and debug a phase-mismatched cable
• Eligible to obtain and maintain an active U.S. Secret security clearance
