# Senior Embedded Performance Engineer

- **Company:** Fractile
- **Location:** Bristol, UK (Remote available)
- **Experience:** Expert
- **Contract:** Permanent contract
- **Skills:** Extract Transform Load (ETL), Software Debugging, Embedded Software, Firmware, Python (Programming Language), Reduced Instruction Set Computing, Graphics Processing Unit (GPU), Information Technology
- **Published:** September 8, 2026
- **Apply:** https://www.collegerecruiter.com/job/2840696814-senior-embedded-performance-engineer

## About the Role

* Proven deeply embedded software experience
 * Strong performance instincts. You can reason about low-level architecture, memory behaviour, and where the cycles are spent
 * Excellent C, and a pragmatic approach to building high-quality, maintainable low-level code
 * Comfortable writing and debugging optimised assembly (RISC-V ideal)
 * Collaborative and high-ownership. You communicate clearly, move fast, and enjoy working through hard problems with others
 * Computer Science, Electronic Engineering, Maths, Physics, or related degree and 3+ years of industry experience, * Experience with GPUs or dedicated ML accelerators
 * Rust and/or Python experience
 * Experience with simulators (functional or performance) and writing validation or benchmarking workloads
 * Familiarity with modern ML inference workloads

## Description

* Write and optimise performance-critical ML kernels in C, with assembly where it matters (RISC-V and our own ISA)
 * Build the low-level control paths that feed those kernels, including scheduling, synchronisation, and data movement
 * Write targeted validation workloads and microbenchmarks to keep simulation and hardware behaviour aligned and performance measurable.
 * Profile, benchmark, and track regressions so performance improvements are real and repeatable
 * Work closely with simulation, hardware, ML, compiler, firmware, and runtime engineers in a tight loop, turning profiling data into architecture feedback and real performance wins.
