ASIC Lead - Analog

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 (Analog) to direct the conception‑to‑production development of Flux’s analog ASICs with multiple high‑speed analog subsystems—20 GSPS data converters, TIAs, ultra‑low‑jitter PLLs, and 100‑lane SerDes fabrics—all with end‑to‑end signal paths that settle in < 1 ns.

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 analog block that underpins our OTPU.

Responsibilities

• Architect and drive full ASIC analog strategy—converter front ends, clocking, optical IO, power regulation and on‑chip non‑linear compute engines—ensuring bandwidth, latency, noise and power budgets are simultaneously met.

• Lead and line‑manage 6 - 12 analog IC and physical‑layout engineers: goal‑setting, performance reviews, recruiting, and skills development and maintain a culture of rapid, first‑time‑right design.

• Collaborate with digital leads to guarantee end-to-end timing determinism and low-latency control loops.

• Implement agile, milestone‑driven schedules that hit aggressive tape‑out dates; track risk burn‑down and drive cross‑function resolution with digital, photonics, packaging and firmware groups.

• Champion rigorous design‑review and verification processes (block and top‑level), including behavioural modelling, corner / Monte‑Carlo sign‑off, and lab‑to‑simulation correlation.

• Represent analog interests in executive and customer/partner communications; create concise technical roadmaps, risk assessments and silicon performance updates.

Skills & Experience

• 12 + years in analog or mixed‑signal IC design with at least 3 complete tape‑out cycles as Senior IC / Lead on products operating > 10 GHz and achieving < 1 ns end‑to‑end settling time.

• Demonstrated success leading teams that delivered multi‑block analog front ends—ADCs/DACs, TIAs, SerDes, PLL/CDR—into high‑volume production on advanced CMOS nodes.

• Deep expertise in low‑latency sampling circuits, broadband feedback networks, ultra‑low‑jitter clocking, package / PCB co‑design, and parasitic‑aware layout sign‑off.

• Solid understanding of mixed‑signal interaction collaborating with the digital lead and agreeing specification splits.

• Strong preference for AI‑compute silicon experience—analog accelerators for activation functions, non‑linear transforms, layer‑norm or in‑memory compute—with quantified power‑latency achievements.

• Mastery of the standard tool chain: Cadence Virtuoso & SpectreRF, EM extraction (EMX/HFSS), mixed‑signal verification (AMS Designer, Questa ADMS), and production test correlation.

• 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.
