Job Description

Flux Computing designs and manufactures optical processors to train and run inference on large AI models. Join us in London to be part of a highly motivated and skilled team that thrives on delivering impact and innovation at speed.

The Role

We are looking for an experienced Analog Electronics Engineering Manager to lead the development and delivery of the high-speed, analog, and mixed-signal electronics that support our optical compute core. This role combines technical oversight with delivery execution, team leadership, and resource planning.


You will partner with the Electronics Architect to ensure effective execution of the technical strategy--bridging technical development with program and people management. You'll contribute technically while also leading project planning, hiring, mentoring, and cross-functional coordination.


You will work closely with ASIC, Optical, Firmware, and System Reliability teams to ensure that our analog electronics roadmap is aligned with our system performance goals and business milestones.

Responsibilities: People & Execution

Build and manage a high-performing team: recruit, coach, and retain top analog talent through 1:1s, career development, and performance reviews. Drive execution using agile hardware development methods, balancing rapid iteration with reliability and manufacturability. Lead resource planning for PCB fabrication, assembly, and test fixture development. Report program status, risks, and mitigation strategies to senior leadership and stakeholders.

Responsibilities: Technical Leadership

Provide hands-on technical direction across the design and implementation of analog and mixed-signal subsystems, ensuring high-quality execution and timely delivery. Work closely with the Electronics Architect, who owns the overarching technical strategy and system-level architecture, to translate design intent into actionable engineering plans. Guide the team through detailed tasks such as schematic reviews, layout best practices, simulation strategy, and bring-up support, ensuring engineering rigor and design quality. Facilitate cross-functional collaboration with Optical, Embedded Systems, and System Reliability teams to ensure smooth system integration and manufacturability, while advocating for sound analog design principles.
