About us (Stealth mode): We’re a stealth, venture-backed healthtech building a next-generation wearable molecular sensing platform, leveraging novel light-based sensing in a wearable form factor. Our mission is to turn the body’s molecular signals into a continuous source of truth - unlocking real-time biochemical clarity for areas like fertility, inflammation, metabolic health, and recovery. Today’s wearables track proxies (heart rate, sleep, movement), but the biology that drives health still lives in episodic, invasive lab tests. We’re closing that gap. The role: We’re hiring a BioMEMS / Microfluidics Engineer as a foundational technical hire to lead the design, prototyping, and translation of our microneedle ISF sampling and microfluidic subsystem. You’ll own the full fluidic path - from skin interface and sampling through transport, priming/venting and bubble management, to the flow-cell where sensing occurs. This role is central to platform reliability: your work directly impacts sample quality, yield, lag time, robustness during wear, and ultimately the user experience. As we scale, there’s a clear pathway to technical leadership - owning this subsystem end-to-end and building a small team around you. You will own: • Own the dermal interstitial fluid sampling & microfluidic cartridge architecture end-to-end., • Lead microneedle strategy and integration: define requirements, support design/selection, and manage external manufacturing partners (DfM feedback loops, tolerances, QC, sterilisation compatibility)., • Design and prototype wearable microfluidic architectures that perform under real-world conditions (motion, temperature changes, multi-hour wear)., • Develop reliable initial wetting / priming strategies (e.g., passive capillary and/or prime-then-passive concepts) to ensure repeatable start-up., • Engineer sustained sampling using capillary-microfluidic design principles - prioritising stability and simplicity., • Build robust solutions for sealing, venting, leakage prevention, and bubble/occlusion control., • Define materials and surface treatments for wettability, low sample loss, anti-fouling, and biocompatibility., • Design interfaces and packaging concepts that connect the cartridge to the core sensing module/electronics (under NDA), with manufacturable assembly in mind., • Create test methods/rigs to quantify priming success, flow stability, leakage, clogging risk, and multi-hour performance., • Drive early DfM and scale-up thinking: assembly steps, tolerance stack-ups, supplier readiness, and path to pilot builds. You’ll collaborate closely with leaders across photonics, chemistry, clinical, and product and play a key role in bringing a genuinely cutting-edge wearable technology from first prototypes to pilot-ready systems. The person: Ideal requirements: • PhD (or MSc + 3+ years) in BioMEMS, Microfluidics, Biomedical/Mechanical Engineering or related., • Proven hands-on experience designing capillary-driven / passive microfluidics (wicking, hydrophilic treatments, flow control features like valves)., • Built and owned end-to-end microfluidic systems from at least concept to prototype to repeatable build (and early manufacturability thinking)., • Experience with wearable / skin-interfacing fluidics and the realities of real-world operation (motion, temperature, sweat, long wear), • Strong familiarity with microneedle-based sampling or adjacent minimally invasive sampling approaches including vendor integration if applicable., • Strong experimental mindset: able to design rigorous flow/pressure/volume/reliability tests, analyse data, and iterate quickly., • Comfortable operating in a high-ambiguity, fast-moving early-stage environment. Nice to have (strong signals, not required) • Experience with ISF extraction, priming/first-wet strategies, bubble traps/venting, and anti-fouling / low-loss surface treatments., • Microfluidics that interfaces with optical sensing or biosensing assays (immuno/aptamer/enzymatic)., • Experience with rapid microfluidic fabrication and/or high-precision low-flow systems (µL/min → nL/min)., • Exposure to medical device development standards (e.g., ISO 13485 / ISO 10993) and design controls. Why work for us? • Foundational ownership + real influence: you’ll own a core subsystem end-to-end and directly shape the product roadmap. As we scale, there’s a clear path to technical leadership and building a team around you., • Deep-tech, real-world impact: work at the intersection of BioMEMS, microfluidics, and next-gen sensing to build a platform that can fundamentally change how health is monitored - moving biochemical insight from occasional lab tests to everyday life., • Work with exceptional people: collaborate with top-tier talent from Cambridge and Imperial College and leaders across sensing, chemistry, and product in a highly ambitious environment., • High-pace, high-support culture: a flat structure, fast iteration, and genuine room to experiment - with regular check-ins and feedback to support your growth and development., • Competitive compensation & meaningful equity: we offer competitive salary and significant early-stage share options, so you’ll own a real stake in what you’re building Apply / get in touch If you’re excited by wearable fluidics and want to build something genuinely new, please apply here or email privately to

About Euphoric Euphoric builds AI-first employee benefits administration software for the world’s largest and most prestigious employers. Born out of Peppy Health — a fast-growing, category-defining Series B startup — we spun out in May 2025 to tackle a far bigger opportunity. Global employers spend $3–5 trillion on benefits every year. It’s their second-largest cost after payroll — yet the entire category is still running on legacy systems and outdated assumptions. The space is primed for transformation: despite its scale, it’s been almost completely overlooked by AI-first startups. Incumbents — including one U.S. heavyweight with $2B+ in annual revenue — are constrained by archaic tech stacks and can’t move fast enough to innovate. And this isn’t just a massive market — it’s genuine “tech for good.” Smarter benefits administration, richer analytics, and clearer communication have the power to directly improve the everyday lives, wellbeing, and financial security of millions of employees worldwide. We’re a sharp, high-velocity team with bold ambitions, obsessed with building category-defining technology and partnering with exceptional people who want their work to truly matter. We closed our seed round in October 2025 and are building from a position of strength with a long cash runway. The Role We are looking for a Lead AI Engineer to drive the technical evolution of our AI-first platform and serve as our resident expert. You won't just be tuning hyperparameters in a notebook; you will be a core software engineer architecting the complex systems that make AI useful in production. In the immediate future, your time will be split between crafting complex AI processing architectures (40%) and hands-on data/backend engineering (40%), with the rest spent doing whatever is needed to ship. As we mature, your focus will shift toward closing the loop: using real-user data to optimize the platform via online evaluation and targeted, data-driven models. What You’ll Do • Architect & Engineer AI Systems: You won’t just call an API; you will build robust processing architectures that leverage off-the-shelf LLMs, RAG pipelines, and context engineering to solve hard problems. You will benchmark these systems rigorously to ensure they actually work, not just "feel" smart., • Build the Backend Foundation: You will spend significant time in Python (FastAPI, SQLAlchemy) building the APIs, data structures, and services that power the product. You are an engineer who ensures the "AI" is delivered on reliable, production-grade rails., • Close the Data Loop: As we launch, you will lead the transition from "zero-shot" implementations to data-driven optimization. You will instrument data collection, design online evaluation metrics, and deploy simple, effective ML models (e.g., logistic regression, boosted trees) to optimize user outcomes based on real feedback., • Be a "Full Stack" Partner: While the backend/data is your home, you are willing to jump into the frontend (React/TS) to implement features (AI or not) or debug an integration. You understand that an algorithm isn’t "done" until the user interacts with it successfully., • Mentor & Lead: You will work alongside full-stack engineers, upskilling the team on AI concepts and best practices. You are the "from-the-trenches" expert who helps the team distinguish between Twitter hype and engineering reality., • Strategic Advising: You will help Product and Leadership navigate the map of what’s valuable and what’s possible, steering the roadmap toward features that achieve business impact through data-driven optimization. Skills & Experience • Production Engineering (5+ years): You are a strong software engineer first. You have extensive experience building and maintaining backend services in Python (ideally FastAPI or similar async frameworks) deployed to modern cloud providers (GCP/AWS) or point solutions (Railway, Render, Vercel), • Applied AI Architecture: You have built complex applications using Foundation Models / LLMs. You understand context window management, prompting strategies, and how to chain models together to achieve reliable results., • True ML Fundamentals: You aren't limited to APIs. You have a background in training and evaluating models (TensorFlow/PyTorch/Keras/Scikit-learn) and know when a simple classifier is better than a generative model., • Data Fluency: You understand how to build datasets from scratch (bootstrapping, crowdsourcing) and how to evaluate them (cross-validation, precision/recall, business metrics)., • Team-Oriented Mindset: Strong communication skills for explaining complex ideas to technical and non-technical audiences, and a passion for collaborating within cross-functional teams., • Passion and Pride in Shipping: A do-whatever-it-takes attitude to deliver against important business goals that help the entire team win., • Pragmatic Best Practices: An overarching desire to build efficient, scalable, and maintainable code, while managing the tradeoffs between technical debt and delivery speed. You’d rather ship a heuristic that solves the user's problem today than a perfect model two weeks late. What We Look For We’re a great bunch but we have some "Euph" cultural non-negotiables. To do well here you will: • Thrive in fast-paced, feedback-rich environments, • Take your work seriously, but not yourself, • Be proactive, playful, and deeply curious, • Want to build something that matters, • Be willing to “do what it takes” What You’ll Get • Base salary c£140k, • Remote-first setup with optional shared work space passes and a hub in London, • Apple devices and the best AI tooling, • Private healthcare via Vitality, • 3% employer pension contribution (min 3% employee contribution), • Meaningful early-stage share opportunities, • 25 days holiday per year, plus bank holidays., • Career rocket fuel - real growth, real ownership, real impact
