Our product is ranked as the UK’s #1 employee assistance programme on Trustpilot, we are proud to support more than 600 small to medium sized organisations (including big names like Hello Fresh, Cleo and Wild) and over 30,000 employees. On the company itself, we operate with an intentionally small HQ team (currently 6 full time employees, 2 are engineers), and we work in-person together in Shoreditch, London. We could go on, but our company handbook is public, so you can read that here to get a fuller sense of the company’s mission, strategy and ways of working. About the role Over the past year we’ve successfully expanded our market presence by refining our product offering and building scalable and cost-effective channels for growth. With rising market demand for impactful mental-health related employee benefits, now’s the time to expand our marketing and sales team to continue on this trajectory. You can think of this role having three important missions at Spill: • Drive growth: You're directly responsible for fuelling Spill’s growth and helping it reach the next stage. Every deal you close brings in revenue that funds product development, new hires, and expansion. At a startup, your individual contribution has an outsized impact on whether the company succeeds or fails., • Solve real problems: Your main focus is to help businesses solve specific people-related challenges by introducing them to a product that can genuinely improve their operations. You're not just selling software - you're helping companies to improve employee productivity, reduce absenteeism, and free up precious HR resource., • Be the voice of the customer: You're the bridge between the market and the product team. You’re responsible for gathering valuable customer insights and sharing with the wider team to help shape the product roadmap, ensuring what gets built actually meets real market needs. What this role will actually do You’ll be the first AE to join our team, reporting directly into the Head of Marketing and Sales. As a two person team you’ll be focused on bringing Spill’s mental health and wellbeing offering to SMEs globally, on the frontlines of advancing our mission to transform the health and happiness of the world, one workplace at a time. This is your chance to join a high-performing team at an inflection point. The product and pitch are proven, and now we need someone who can execute with speed and intensity to help us capture the momentum and scale to the next level. Here are some examples of the types of tasks/projects you’re likely to be working on: • Preparing and presenting product demos. You'll need to build a good understanding of each prospects' pain points and needs at the start of the call, then tailor the product demo to their specific use case., • Managing your pipeline. You’ll be maintaining disciplined CRM hygiene by logging activities, moving deals through stages, and keeping accurate records of all communications., • Nurturing and closing deals. You'll be following up with prospects at various stages, answering questions, and sharing resources to nurture and convert leads post-demo., • Account management: You’ll continue post-sale relationship management to ensure that every new customer has a smooth onboarding experience., • Tracking sales performance: You'll track and monitor your progress toward monthly and quarterly sales targets, calculating what you need to close to hit your numbers. Requirements • You have experience working in a customer facing role. This doesn’t necessarily have to be a sales role, it could be a related field e.g. customer success or account management, recruitment, project management or retail/hospitality management., • You’ve got a basic understanding of full-cycle sales processes including outbound prospecting, discovery, pitching, product demonstration, proposal development, negotiation, and closing., • You thrive in a fast-paced, mission-driven start-up environment. This often means moving quickly, being adaptable and being willing to contribute beyond the remit of your core role., • You’re self-motivated and resilient. You thrive with ambiguity, handle feedback well, and stay motivated without the need for constant oversight., • You’re results driven, competitive and motivated by hitting targets, meeting deadlines and contributing to the overall growth of the company., • You have excellent written and verbal communication, negotiation, and relationship-building skills. That said, we recognise that experience will vary a lot between people, so please don't be put off if you don't meet these criteria exactly. We care about outcomes rather than tickbox criteria, and it's often the case that the perfect person for the role has a CV that looks a little different. Research (by Harvard University) shows that women are particularly likely to second-guess themselves and not apply — so if you're worried you don't meet all the criteria, get in touch anyhow and let us do the worrying. Nice to haves: • You have experience working in a B2B SaaS or SME sales environment, or a mission-driven or healthcare-focused organisation., • You’re comfortable using CRM tools like Hubspot.

About Our Client We're representing a company on a mission to redefine how modern distributed systems are tested and released. Their platform is trusted by engineering teams who demand rock-solid reliability, scalable performance, and deep technical visibility — and it exists because developers deserve something better than what's out there. If you've ever lived through a production outage, had a brutal on-call week, or watched a release slip by weeks because of one killer bug — you'll understand exactly why our client built what they built. If you're passionate about developer-first products, system resilience, and correctness, keep reading. The Role Our client isn't looking for a typical SE. They want an unconventional thinker — someone who gets genuinely energized by breaking things, thrives on chaos, and has the technical chops to deploy a sophisticated testing platform against real-world software and make it sing. You'll split your time between hands-on POC work, customer-facing technical conversations, and thought leadership around a testing paradigm that most engineering teams haven't encountered yet. You'll be the person in the room who actually understands what's happening under the hood — and can make a skeptical senior engineer a believer. What you'll do: • Execute POC engagements that demonstrate real product value to prospective customers, • Lead customer workshops on Property-Based Testing (PBT) and related methodologies, • Support the sales team with technical qualification and consultation, • Find bugs. Break open source software. Make a point of it., • Build, maintain, and deliver product demos that land with technical audiences, • Guide customers and prospects on platform adoption and testing best practices, • Participate in new customer onboarding and early-stage success, • Highly technical — and more importantly, technically curious, • Easily bored; you need new problems to stay engaged, • A natural communicator who can translate complexity for both engineers and executives, • Comfortable under pressure and in tight timelines, • Professional enough for enterprise clients, flexible enough for a fast-moving startup, • Hands-on experience building and running automated tests (integration, end-to-end), • Containerization: Docker, Kubernetes, • Object-oriented programming fundamentals, • Linux-based operating systems, • Scripting: Bash/Shell, Python, or JavaScript, • Data querying: SQL, NoSQL, or equivalent This role requires some travel — client sites, conferences, and occasional visits to our client's HQ. If that's your thing, all the better. Why It's Worth a Look Most SE roles are demo-and-support. This one is different. Our client is building a new category, and the SE who joins now will have outsized influence on how that story gets told technically — and how customers succeed with a platform that genuinely does something new.

We are seeking a Senior Biosensing Scientist to play a foundational role in building the biorecognition layer of our sensing platform. This is not a pure in-house discovery role; instead, you will focus on defining, guiding, and validating externally developed affinity reagents (such as aptamers and synthetic probes) to ensure they integrate with our proprietary continuous sensing hardware. About us (Stealth mode): We’re a stealth, VC-backed deep-tech startup building a next-generation molecular sensing platform, leveraging proprietary 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: You will own the scientific interface between CHUNE’s hardware platform and our external affinity reagent partners. This means translating our unique continuous-sensing product requirements into precise technical specifications and guiding CROs through the development process. Once candidate reagents are delivered, you will lead internal validation, testing them in relevant biological matrices and on our solid-state sensor architectures to determine whether they meet platform performance requirements. You’ll work closely with our hardware, fluidics, and systems engineering teams to ensure reagent performance is evaluated within the real constraints of the device, not just in a vendor’s benchtop assay You will own: • Target Specifications: Defining target product requirements for affinity reagents, including physiological concentration ranges, matrix contexts, selectivity profiles, and binding kinetics (Kd, kon, koff)., • Vendor Management: Acting as the primary scientific lead with external aptamer/optimer vendors. You will guide them through reagent design, screening requirements, off-target panels, and success criteria., • Data Review & Downselection: Critically evaluating vendor outputs (sequence packages, binding data, selectivity reports) and deciding which candidates progress to in-house testing., • Internal Assay Validation: Developing and executing assays to test whether externally developed binders are fit for our specific use cases (e.g., performance in Interstitial Fluid, reproducibility, and reversibility for continuous monitoring)., • Hardware Integration: Collaborating with engineering teams to evaluate reagent compatibility with specific surface immobilisation techniques and our proprietary continuous readout systems., • Strategic Frameworks: Building an internal framework for reagent benchmarking, quality control, and acceptance criteria across our biomarker pipeline. You’ll collaborate closely with leaders across photonics, microfluidics, 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 + 2+ years’ experience) in biochemistry, bioengineering, or a related field, • Hands-on experience working with aptamers, optimers, or other synthetic affinity probes., • Deep understanding of binding performance metrics (affinity, specificity, sensitivity) and experience defining Kd, kon, and koff requirements for real-world assays., • Experience working with external partners, CROs, or vendors, with the ability to translate product needs into clear scientific briefs., • Proven track record of designing assays to validate binder performance in complex biological matrices (serum, plasma, ISF, etc.)., • Strong understanding of biomarker biology, including physiological concentration ranges, relevant interferents, and matrix effects, • Strong analytical skills to critically challenge vendor data and troubleshoot underperforming reagents. Nice to have (strong signals, not required) • Development of custom aptamers or nucleic-acid–based probes (e.g., optimisation, truncations/modifications, or SELEX exposure)., • Experience with SPR, BLI, QCM, or related kinetics / interaction analysis tools, • Familiarity with continuous or real-time biosensing platforms., • Experience working with microfluidic, wearable, or lab-on-chip systems., • Experience validating biomarkers in interstitial fluid (ISF)., • Experience handling skin tissue samples. Why work for us? • Foundational ownership: You’ll be a core contributor to the biorecognition layer of the platform, directly shaping sensor performance, biomarker selection, and long-term reliability. Your work will define what we can measure and how well we can measure it., • Deep-tech, real-world impact: Work on genuinely novel continuous biosensing technology with the potential to transform how health is monitored - moving biochemical insight from occasional lab tests to continuous, real-time understanding., • 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 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 molecular monitoring and want to build something genuinely new, please apply here or email privately to
