Company

hirify.global develops autonomous and defense systems across air, land, sea, space, and cyber domains.

What you will do

• Analyze wideband complex-IQ recordings from known and unfamiliar RF systems.
• Characterize waveforms, modulation, synchronization, channel access, frequency hopping, framing, and coding.
• Design controlled experiments and develop algorithms for detection, demodulation, classification, tracking, and protocol recovery.
• Implement and optimize production DSP capabilities in modern C++ for Linux.
• Build synthetic waveforms, replay fixtures, automated tests, and maintainable algorithm components.
• Validate performance using laboratory, over-the-air, conducted, and field-recorded data while collaborating with RF, FPGA, embedded software, data science, test, and mission teams.

Requirements

• BS or higher in Electrical Engineering, Computer Engineering, Applied Physics, or a related technical field.
• Substantial professional experience developing RF, communications, radar, electronic-warfare, or related signal-processing systems.
• Strong DSP and digital-communications fundamentals, including filtering, FFT and time-frequency analysis, detection and estimation, synchronization, modulation, and channel coding.
• Experience analyzing real complex-IQ data, investigating unfamiliar signals, designing controlled experiments, and debugging DSP algorithms.
• Production-quality C++ development in Linux, automated testing, recorded-data replay, and Git-based collaboration.
• U.S. Citizenship is required; ITAR/EAR compliance applies.

Nice to have

• Reverse-engineering undocumented wireless waveforms and protocols.
• Software-defined radio, RF laboratory, frequency-hopping, spread-spectrum, OFDM, cellular, telemetry, radar, or electronic-warfare experience.
• FPGA-based DSP, fixed-point implementation, hardware/software partitioning, or high-rate sample transport.
• Real-time C++ optimization using profiling, SIMD, threading, bounded queues, and reusable buffers.
• Direction finding, antenna arrays, emitter geolocation, or machine learning applied to RF data.

Culture & Benefits

• Individual-contributor role with hands-on ownership from signal investigation through integration and field validation.
• Medical, dental, and vision benefits.
• 401(k) with company matching.
• 9/80 work schedule and paid holiday shutdown.
