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.
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.
