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’re searching for Senior Embedded Engineers to design and build high-performance tooling supporting OTPU hardware development. You will own tools related to hardware safety, calibration, debugging, and validation, from concept to deployment, iterating rapidly to deliver robust embedded solutions that ensure our OTPUs operate safely, efficiently, and at peak performance.

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, primarily using Python for rapid prototyping.
• Define and implement CI/CD infrastructure tailored for embedded development to enable fast iteration and system integrity.
• Create systems for real-time monitoring, diagnostics, and fault handling across OTPU hardware.
• Establish boundaries between prototypes and production code to ensure maintainability and velocity.
• Collaborate with optical, hardware, and software teams to align on interfaces, requirements, and performance goals.

Skills & Experience

• 5+ years experience with hardware bring-up, calibration, and debugging of systems such as SoCs, FPGAs, or AI accelerators.
• Deep proficiency in C/C++ for embedded applications, understanding real-time constraints, memory models, and hardware interfaces.
• Strong Python skills for prototyping, automation, and testing.
• Experience building CI/CD pipelines for embedded development, including automated flashing and artifact tracking.
• Proficiency with hardware debugging tools (oscilloscopes, logic analyzers, JTAG) and electrical signal interpretation.
• Solid understanding of hardware/software boundaries, including interrupt handling, bus protocols (e.g., 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 rapidly growing AI company.
• Based in 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 extra £24,000/year incentive is offered for those living within 20 minutes.
• Comprehensive healthcare insurance.
• Private use of our 3D printer.

If you are passionate about advancing AI and excel in fast-paced environments, we want to hear from you. Apply now to join Flux and shape the future of computing.
