Job description

Company Overview

Flux has developed the world’s first Optical Tensor Processing Unit (OTPU). Flux's OTPUs are custom-designed AI accelerators optimized 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 are seeking Senior Embedded Engineers to design and build high-performance tooling supporting our OTPU hardware development. You will own tools related to hardware safety, calibration, debugging, and validation. Your goal is to go from concept to deployment, rapidly iterating, prototyping, and delivering robust embedded solutions that enable OTPUs to operate safely, efficiently, and at peak performance.

Responsibilities

• Architect and develop robust tooling for hardware validation and bring-up, with rapid prototyping in Python and a clear transition to production code.
• Design and implement embedded systems for hardware safety, synchronization, and low-level control.
• Develop calibration and debugging tools, primarily in Python.
• Establish CI/CD infrastructure tailored for embedded development to facilitate fast iteration and system reliability.
• Create systems for real-time monitoring, diagnostics, and fault management of OTPU hardware.
• Define boundaries between prototype and production code to ensure maintainability and long-term velocity.
• Collaborate with optical, hardware, and software teams to align on system interfaces, requirements, and performance goals.

Skills & Experience

• 5+ years of experience with hardware bring-up, calibration, and debugging of custom systems (e.g., SoCs, FPGAs, AI accelerators).
• Strong proficiency in C/C++ for embedded applications, with understanding of real-time constraints, memory models, and hardware interfaces.
• Excellent Python skills for prototyping, automation, and test development.
• Experience building CI/CD pipelines for embedded systems (e.g., automated flashing, testing, artifact management).
• Proficiency with hardware debugging tools (oscilloscopes, logic analyzers, JTAG) and interpreting electrical signals.
• Solid understanding of hardware/software boundaries, including interrupt handling, bus protocols (like PCIe), and memory-mapped I/O.
• Excellent communication skills; ability to thrive in fast-paced, cross-disciplinary startup environments.

Details

• Salary: £135,000 - £165,000 depending on experience.
• Stock options in a growing AI company.
• Location: Our new 5,000 sq. ft. office in Kings Cross, London.
• All employees are expected to work from our London HQ and live within a 45-minute commute; an additional £24,000/year incentive is offered for those living within 20 minutes.
• Comprehensive healthcare insurance.
• Private access to our 3D printer.
