Embedded Audio Firmware Engineer

Degree (1st or 2.1) or equivalent, in Electronics, Embedded Software, Signal Processing or related discipline

Strong professional experience of developing embedded firmware in C/C++ for fixed-point and floating-point DSPs and embedded platforms.

Ability to go from a Matlab algorithm design to an embedded firmware design in C/C++ for fixed-point and floating-point

DSPs and embedded platforms.

Proven ability to optimize firmware: cycle counting, memory layout, DMA usage, cache behavior, minimizing latency and jitter.

Experience in several of the following: filter design, adaptive filtering, audio / sensor signal processing; FFT/spectral based processing and machine learning in an audio context.

Solid understanding of embedded software fundamentals:

register-level programming, memory-mapped I/O

concurrency (ISRs, RTOS tasks), race conditions, timing determinism

fixed-point arithmetic, numerical precision, and overflow/underflow management

Proven ability to optimize firmware: cycle counting, memory layout, DMA usage, cache behavior, minimizing latency and jitter.

Ability to pick up a broad range of responsibilities from design and simulation to prototyping and implementation on custom hardware.

Ability to plan and work to a managed schedule across multiple functional teams.

Comfortable with toolchains and build systems:

GCC/LLVM-based toolchains, cross-compilation

CMake/Make, Meson, linker scripts, map files

Strong debugging skills with hardware and firmware:

JTAG/SWD debugging

root-cause analysis of timing and performance issues

Source control expertise (Git, GitHub) and disciplined engineering practices (code reviews, CI).
