ASIC Digital Design Manager

The Role
We're searching for an
ASIC Digital Design Manager
to lead and deliver the digital subsystems of our next-generation high-speed mixed-signal ASICs. This is a hands-on leadership role with a strong focus on execution speed, first-time-right delivery, people management, and cross-functional alignment.

You will drive your team to deliver complex digital systems that integrate high-bandwidth interfaces, deterministic control loops, and advanced mixed-signal blocks—on schedule, on budget, and with uncompromising quality. As both a leader and technical authority, you will mentor engineers, set a high bar for performance, and ensure the program executes with precision from concept through tape-out to mass production.

Responsibilities

• Execution Ownership & Speed – Lead end-to-end delivery of digital subsystems (RTL, synthesis, DFT/DFD, timing closure, physical implementation), ensuring aggressive schedule targets are met without compromising quality.
• Right-First-Time Delivery – Build and enforce processes that prioritize robust design, rigorous verification, and silicon bring-up strategies that achieve first-silicon success.
• Line & Performance Management – Manage, mentor, and grow a high-performing team of 6–12 digital and mixed-signal engineers. Own goal-setting, performance reviews, career development, and hiring, while fostering a culture of accountability and continuous improvement.
• Cross-Functional Alignment – Drive seamless collaboration across analog, verification, layout, packaging, firmware, and test teams to keep programs moving fast and aligned from architecture → spec → implementation → sign-off → bring-up.
• Program Leadership – Define and track aggressive schedules, resource plans, and risk-mitigation strategies. Communicate progress, trade-offs, and escalation paths clearly to executives and customers.
• Technical Direction – Provide architectural and implementation guidance for high-speed digital subsystems, including multi-lane data paths, clocking, and mixed-signal control loops.
• Culture of Speed & Quality – Champion design automation, streamlined methodologies, and knowledge sharing to deliver high-quality silicon on tight timelines.

Skills & Experience

• 10+ years of digital ASIC development, with at least 3 full product cycles successfully executed from specification to high-volume production.
• Proven track record of driving on-time, first-time-right delivery of complex, high-performance ASICs with mixed-signal interfaces (e.g., SerDes, DACs/ADCs, RF SoCs, display/camera pipelines).
• Strong expertise in RTL design (SystemVerilog/Verilog), CDC/RDC, STA, synthesis, P&R, power intent (UPF/CPF), and DFT/DFD methodologies.
• Deep understanding of mixed-signal interaction (coupling, jitter, supply noise, calibration) and ability to partner effectively with analog teams on specification splits.
• Demonstrated success in line management and performance management, including hiring, mentoring, and building high-performing engineering teams.
• Skilled in fast-paced, cross-functional program leadership with a proven ability to manage schedules, risks, and vendor/foundry relationships.
• Outstanding written and verbal communication; confident presenting clear, concise program and technical 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.
