What you will do

• Design, implement, maintain, and release audio signal-processing software in C/C++ for embedded fixed-point and floating-point DSP platforms.
• Convert MATLAB or Python reference models and algorithm specifications into efficient production implementations, resolving precision, headroom, and numerical issues.
• Build unit, bit-exact, tolerance-based, host-simulation, and continuous-integration tests for DSP code.
• Profile and optimize target implementations for cycles, memory, and power, and communicate architectural trade-offs.
• Develop Python tooling for parameter definition, tuning, code generation, and test automation; port algorithms across DSP platforms.
• Diagnose defects across algorithms, firmware, and hardware; prototype features, contribute to design reviews and documentation, and mentor early-career engineers.

Requirements

• Bachelor’s degree or equivalent in Electrical Engineering, Computer Engineering, Computer Science, Audio Engineering, Mathematics, or a related field.
• Approximately 5 years of relevant industry experience developing embedded or real-time software, including signal processing, or equivalent demonstrated competence.
• Strong C and/or C++ skills with experience shipping production embedded code.
• Knowledge of DSP fundamentals, including sampling, z-transform, FIR and IIR filters, frequency transforms, and multirate processing.
• Experience implementing and verifying DSP algorithms on resource-constrained targets, including fixed-point arithmetic.
• Proficiency in Python or MATLAB for analysis, tooling, and test automation.
• Experience with Git, code review, automated testing or continuous integration, and profiling and debugging on target hardware with embedded toolchains and debuggers.
• Ability to communicate technical ideas clearly in writing and conversation with colleagues from other disciplines.
• Applicants must be able to work from the Glasgow or Louisville office 5 days per week.

Nice to have

• Experience with Cadence Tensilica HiFi, Qualcomm Kalimba, Analog Devices DSPs, or Arm Cortex-M with CMSIS-DSP, including SIMD or vector optimization.
• Experience building embedded developer tooling, code generation, host-based simulation, or CI infrastructure.
• Experience with audio, speech, acoustics, headphones, hearables, telephony, or Bluetooth audio products.
• Familiarity with adaptive filtering or real-time control concepts used in active noise cancellation; specialist ANC experience is not required.
• Experience mentoring less experienced engineers and taking ownership of work handed over from others.
• Curiosity, a growth-oriented mindset, and a record of following through on commitments.
