The Role
Lead the digital design of high-speed mixed-signal ASICs, mentor a team, manage project execution, and ensure deliverables meet specifications in a fast-paced AI environment.
Summary Generated by Built In

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

The Role

We’re searching for a ASIC Lead (Digital) who can drive a complex, high‑speed mixed‑signal chip from concept to mass production while line‑managing and mentoring a world‑class team of design engineers.

You will own delivery of the digital subsystems that stitch together > 100 high‑bandwidth lanes, interface to fast‑settling DACs and ADCs, and run deterministic control loops at > 100 MHz clock rates.

This is a hands‑on leadership position: you will manage and mentor a multidisciplinary team, own program execution to tape‑out, and serve as the principal technical authority for every digital block that underpins our OTPU.

Responsibilities

  • Architect, plan and deliver the digital top level of a multi‑lane optical compute ASIC—RTL, synthesis, DFT/DFD, static‑timing and physical implementation.

  • Lead cross‑functional teams (digital, analog, verification, layout, packaging, test, firmware) through all silicon lifecycle stages: architecture ► spec ► RTL ► physical design ► sign‑off

  • Lead and line‑manage 6‑12 digital & mixed‑signal engineers: goal‑setting, performance reviews, recruiting, and skills development and maintain a culture of rapid, first‑time‑right design.

  • Define and track project schedules, budgets and risk‑mitigation plans; present status, trade‑offs and escalation options to executives and customers.

  • Collaborate with analog leads on fast‑settling current‑steering DACs, high‑speed SerDes, PLLs and clock‑mesh networks to guarantee end‑to‑end timing determinism and low‑latency control loops.

  • Drive design verification strategy—UVM test‑benches, gate‑level sims, FPGA prototyping—and own silicon bring‑up test plans that hit first‑silicon functional goals.

  • Optimise multi‑lane protocols for bandwidth scaling, skew management and power efficiency; integrate error monitoring, calibration engines and field‑update hooks.

  • Encourage a culture of continuous improvement—methodology automation, design‑flow enhancements, documentation and knowledge sharing.

Skills & Experience

  • 12 + years of digital ASIC development, with at least 3 full product cycles taken from specification through volume production.

  • Demonstrated success leading a digital team that delivered high speed ASICs containing high‑speed mixed‑signal interfaces (display drivers, image sensors, SerDes, RF SoCs, etc.).

  • Strong command of RTL design (SystemVerilog / Verilog), CDC/RDC, STA, place‑and‑route, power intent (UPF/CPF) and DFT/DFD methodologies.

  • Demonstrated success coordinating multi‑lane data paths, clock distribution and fast‑settling DAC / ADC control loops while closing timing and power at advanced nodes.

  • Solid understanding of mixed‑signal interaction: coupling, jitter, supply‑noise and on‑chip calibration; able to read analog schematics and agreeing specification splits.

  • Experience with high‑speed display or camera pipelines—timing controllers, MIPI / DSI / CSI, LVDS, DisplayPort, HDMI, or similar—strongly desired.

  • Prior people‑management responsibility: hiring, mentoring, salary planning and performance management for engineers.

  • Excellent project‑leadership skills: schedule ownership, risk analysis, vendor/foundry engagement, first‑pass success mindset.

  • Outstanding written and verbal communication; comfortable presenting detailed technical and program status to executives, customers and cross‑site teams.

Compensation & Benefits

  • $221,000 – $270,000 + annual salary, depending on experience, skills, and location.

  • Competitive stock options, you’re not just part of the journey, you will own a piece of it.

  • Work from our office in The Domain, right in buzzing Austin with parking available for easy access.

  • Live within 45 minutes of the office? Perfect. Live within 20 minutes? We’ll add an extra location bonus ($24K) to your salary.

  • We offer financial and operational relocation support (US and abroad), through a dedicated third-party provider who is on hand to make your move to Austin as seamless as possible.

  • We offer visa sponsorship so if we make you an offer we will make every reasonable effort to secure you a visa, but we may not be able to sponsor visas for every role and candidate.

  • We’re in the process of setting up a US group policy once we have 5+ employees. In the meantime, we’re providing a health insurance stipend of $800/month to offset costs. Once the group policy is live, Flux will cover 100% of the employee premium, and offer options like dental, vision and life insurance with an aim to remain competitive among Austin tech and start up employers.

  • We offer US employees access to a 401(k) retirement savings plan and we plan to introduce an employer match in line with Austin tech market norms (commonly in the 4-5% range). Our goal is to keep our retirement benefits competitive while we scale.

  • Top of the line, high-spec tech for everyone.

  • Sony noise-cancelling headphones and ergonomic setups to keep you comfortable and focused.

  • Personal company card to spend on tools that help you do your job - like ChatGPT Pro or anything else that boosts your workflow.

  • Periodic travel to London HQ and regular team socials.

  • 33 days of paid time off (PTO), including US federal holidays.

Due to U.S. export control regulations, candidates’ eligibility to work at Flux depends on their most recent citizenship or permanent residency status. We are generally unable to consider applicants whose most recent citizenship or permanent residence is in certain restricted countries (currently including Iran, North Korea, Syria, Cuba, Russia, Belarus, China, Hong Kong, Macau, and Venezuela). Applicants who have subsequently obtained citizenship or permanent residency in another country not subject to these restrictions may still be eligible.

Please note: we receive many applications, and this role is not at the top of our priority list. We anticipate reviewing all submissions within 3 weeks, and will contact you if you are shortlisted.

We do not accept unsolicited CVs from recruitment agencies, will not be liable for any fees, and prohibit unauthorised use of our company name in recruitment activities.

We’re building fast and that includes our benefits. More exciting additions are coming soon for the Flux crew.

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.
