About the job

Flux Computing designs and manufactures optical processors to train and run inference on large AI models. We are looking for an experienced Analog Electronics Engineering Manager to lead the development and delivery of 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 include building and managing a high-performing team through recruitment, coaching, and performance reviews, driving execution using agile hardware development methods, leading resource planning for PCB fabrication, assembly, and test fixture development, and reporting program status, risks, and mitigation strategies to senior leadership. Technical leadership responsibilities include providing hands-on guidance across the design and implementation of analog and mixed-signal subsystems, working with the Electronics Architect to translate design intent into actionable engineering plans, guiding detailed tasks such as schematic reviews, layout best practices, simulation strategy, and bring-up support, and facilitating cross-functional collaboration with Optical, Embedded Systems, and System Reliability teams to ensure smooth system integration while advocating sound analog design principles. The ideal candidate has a BEng/MEng or PhD in Electrical/Electronic Engineering or a related field, 10+ years designing high-performance analog or mixed-signal hardware with 3+ years leading engineering teams, deep expertise in low-noise, wide-bandwidth analog front-ends (TIA, LNA, ADC/DAC interface), high-speed differential signalling, impedance control, signal-integrity mitigation, fluency with EDA and simulation tools, and solid grounding in EMC/EMI, thermal management, and automated test. Excellent communication skills, ownership of complex electronics products from concept to volume manufacture, and ability to work independently in a fast-paced, collaborative environment are essential. Compensation includes a competitive salary, stock options, visa sponsorship and full relocation support, full BUPA healthcare and dental cover, high-spec tech setups, chef-cooked dinners, monthly off-site socials, 25 days paid holiday plus UK bank holidays, access to an in-house 3D printer, Cycle2work scheme, personal company card for tools, and a pension plan.
