Head of Engineering (Photonics & Scale-up Focus)

The Head of Engineering owns taking technology from one to scale, with primary ownership of photonic integrated circuits (PICs) and associated light sources and detectors. This role exists to turn proven concepts into a product that ships reliably, repeatedly, and at high standards. The photonic subsystem is the pacing item: its maturity defines packaging, integration, test strategy, and much of the downstream electronics, firmware, and software. This is not a generalist engineering role. This is a photonics-first scale-up role. The Role As Head of Engineering, you are accountable for execution reality, with emphasis on photonics. You own maturing photonic technology into something production-ready. At the same time, you are expected to develop an insanely steep learning curve across adjacent domains (MEMS, electronics, mechanics, firmware, and software) not to reinvent them, but to understand them deeply enough to make correct scale-up decisions. You take concepts from the Head of R&D and: • Stress-test them against production constraints • Translate them into manufacturable designs • Manage the suppliers and partners needed to make them real You must be able to interpret test data across non-photonic domains, understand failure modes, and reason about the mechanical, electrical, and software “glue” that holds the system together. You lead by doing. You set standards by example. You are deeply hands-on in the lab and in code when it matters. This role requires intensity. You must be willing to work extended hours and weekends when required. What You’ll Do • Own delivery of PICs, lasers, and detectors from design freeze through scale-up. • Drive photonic maturity: stability, yield, repeatability, and margin. • Develop rapid working understanding of:MEMS behaviour and test resultsElectronics performance, noise, and interfacesMechanical constraints and packaging interactionsFirmware and software behaviour at system level • Without reinventing these domains, unless you have strong, evidence-backed ideas to improve them. • Manage and challenge external suppliers across MEMS, electronics, packaging, and test. • Lead photonics-centric automation across:Design and layout checksSimulation and modellingTest, characterisation, and calibrationTape-out, DRC, LVS, and sign-off • Be hands-on in the lab:Optical alignment and characterisationDebugging cross-domain issues using dataCorrelating measurements with models • Write and maintain Python-based tooling for:Test automationData analysisPerformance tracking and reporting • Define clear component-level performance targets and acceptance criteria. • Work closely with Head of R&D (architecture) and Head of Foundry (process and yield). Python coding and lab competence are non-negotiable. Required Background You must have: • Deep, hands-on photonics experience (PICs + lasers and/or detectors) • Plus technical experience with either one of the following:MEMS sensor systemsASIC / FPGA You must have demonstrated: • Ability to take photonic technology beyond prototype • Ability to interpret and act on cross-domain test results • Ability to work productively with suppliers and partners • Ability to write and talk confidently and clearly about deep tech How this role fits • Reports directly to the CEO • Owns tape-out execution for photonic components • Can be blocked by Head of R&D, Head of Foundry, or CEO • Main reporter of progress towards product, using this skill for whitepapers, conferences, grant proposals • External owner of photonic production readiness and performance Who This Role Is For This role is for someone who: • Has deep photonics expertise and wants to make it real at scale • Learns adjacent domains at extreme speed to make good decisions • Is comfortable relying on domain experts but can challenge them using data • Is bullish, demanding, and unwilling to accept sloppy execution • Has high standards, high integrity, and low ego • Does not need to reinvent everything to add value • Is accountable for outcomes, not activity What success looks like Photonics maturity & technical control • Photonic components behave predictably across wafers, runs, operating conditions, and time. Clear understanding of performance margins, sensitivities, and yield drivers for PICs, lasers, and detectors • Photonics-related failure modes are understood, monitored, and shrinking - not rediscovered • Fewer surprises at system integration because the photonic core is stable and well-characterised Automation, repeatability & standards • Automated, repeatable photonics design, test, and release workflows are in place and actively used • Automation does not degrade quality, standards are preserved or raised as scale increases • Tape-out, DRC, LVS, test, and calibration processes are version-controlled, auditable, and boring (in the good way) • Manual heroics are being replaced by systems that work every time Cross-domain understanding & integration readiness • MEMS, electronics, firmware, and software issues are caught early because you can interpret the data and ask the right questions • You do not reinvent adjacent domains but you understand them well enough to:Challenge assumptionsSpot inconsistenciesPrevent late-stage integration failures • The mechanical, electrical, and software “glue” holding the product together is increasingly robust and explicit Cost, supply chain & leverage • BOM costs are understood, tracked, and actively driven down without compromising performance or reliability • Critical components have:Clear cost driversIdentified second sources or credible backup plansExplicit risk registers where second sourcing is not yet viable • Supplier dependencies are intentional, not accidental • External suppliers, consultants, and third parties are:Clearly scopedActively managedHeld to demanding technical and delivery standards Execution & organisational impact • Suppliers move faster because expectations, interfaces, and acceptance criteria are clear. • Engineering execution becomes more predictable without becoming slower • Trade-offs between performance, cost, risk, and schedule are explicit and evidence-based • The team feels pressure but also clarity. There is less thrash and fewer “emergency” surprises • The technical bar across the organisation is visibly higher:Better experimentsCleaner dataSharper questionsFewer hand-wavy explanations Visibility & conviction • Regular demos presented to the board on product maturity & hitting performance targets Working with us • Compensation: Our framework is built on fairness and transparency, with regular reviews to reflect growth and performance. • Benefits: Share options, pension, and private medical insurance. • Culture: A deep-tech rocketship backed by leading investors. We’re building breakthrough technology with real commercial impact. Pace is high. Standards are higher. Zero Point Motion is determined to foster belonging and empowerment at work. We are committed to providing a work environment where there’s a zero-tolerance approach to discrimination, and everyone is treated with respect. Equity, diversity and inclusion are central to our mission, and we strongly encourage candidates of all different backgrounds and identities to apply.
