Job Description

Company Overview

Flux has developed the world’s first Optical Tensor Processing Unit (OTPU). Flux's OTPUs, are custom-designed AI accelerators, which are optimised for training and inference of large AI models. Join us in London to be part of a dynamic team that thrives on innovation and speed.

The role

We’re searching for Senior Embedded Engineers to design and build ultra-high performance tooling that supports our OTPU hardware development. You will own tools that span hardware safety, calibration, debugging, and validation. Your mission is to go from concept to deployment - rapidly iterating, prototyping, and delivering robust embedded solutions that enable our OTPUs to run safely, efficiently, and continuously push the limits of their performance envelope.

Responsibilities

  • Architect robust tooling for hardware validation and bring-up, with rapid prototyping in Python and a clear path to production-grade implementations.
  • Design and implement embedded systems for hardware safety, synchronization, and low-level control.
  • Develop calibration and debug tooling, with rapid prototyping primarily in Python.
  • Define and implement CI / CD infrastructure tailored for embedded development, ensuring fast iteration and high confidence in system integrity.
  • Create systems for real-time monitoring, diagnostics, and fault handling across OTPU hardware.
  • Define and enforce clear boundaries between prototype and production code to ensure long-term velocity and maintainability.
  • Collaborate closely with optical, hardware, and software teams to align on system interfaces, requirements, and performance goals.

Skills & Experience

  • 5+ years experience with bring-up, calibration, and debug of custom hardware systems (e.g. SoCs, FPGAs, or AI accelerators)
  • Deep proficiency in C / C++ for embedded applications, with a solid grasp of real-time constraints, memory models, and low-level hardware interfaces
  • Strong Python skills for prototyping, automation, and test harness development
  • Demonstrated experience building CI / CD pipelines for embedded development (e.g. automated flashing, test orchestration, artifact tracking)
  • Proficiency with hardware debugging tools (oscilloscopes, logic analyzers, JTAG, etc.) and interpreting electrical signals in context.
  • Solid understanding of hardware / software boundaries, including interrupt handling, bus protocols (e.g.PCIe), and memory-mapped I / O.
  • Excellent written & verbal communication; thrive in fast-paced, cross-disciplinary start-up settings.

    • Details

  • Competitive salary ranging from £135,000 to £165,000, depending on experience.
  • Stock options in a rapidly growing AI company.
  • Based in our new 5,000 sq. ft. office in the AI hub of Kings Cross, London.
  • To foster collaboration in our high-growth environment, we require all employees to work from our London HQ and live within a 45-minute commute. We offer an extra £24,000 / year incentive for those living within 20 minutes.
  • Comprehensive healthcare insurance.
  • 25 days PTO policy plus bank holidays.
  • Private use of our 3D printer.

    • If you are passionate about pushing the boundaries of what's possible in AI and thrive in a high-energy, fast-paced environment, we want to hear from you. Apply now to join Flux and be a key player in shaping the future of computing.
