Senior Product Engineer London Hybrid Startup 90,000 - 130,000 + meaningful equity Tech stack: Experience required across any of the following: Golang Rust TypeScript, Node.js React.js, Next.js AWS or GCP Most B2B SaaS products are effectively dashboards on top of a database. This isn't that. We're working with an Agentic AI startup building infrastructure and intelligent software systems that sit underneath large scale operational workflows and real time decision making processes. The platform processes very high volumes of live data, powers complex orchestration pipelines, and delivers AI driven functionality directly into customer environments at enterprise scale. The engineering challenges are genuinely difficult. Not "we use Kubernetes so we're scaling" difficult. More the kind of problems involving distributed systems, real time data ingestion, AI orchestration pipelines, and building software that customers rely on day to day inside production environments. The team is still small enough that every engineer materially changes the trajectory of the business. No giant hierarchy, no endless roadmap theatre, no Jira archaeology expedition trying to work out why a ticket exists. That means speaking to customers, understanding commercial context, shaping product direction, building systems, shipping to production, monitoring outcomes, and iterating quickly. You'll be working across: Real time event streaming systems handling very high traffic volumes AI powered workflows and orchestration pipelines Product engineering across backend infrastructure and frontend applications CRM and third party integration infrastructure Identity resolution and large scale data processing Systems where reliability and speed both matter because customers actively use what gets shipped The environment is best suited to engineers who: Enjoy ambiguity rather than waiting for perfect specs Think commercially as well as technically Want ownership rather than ticket queues Care about shipping quickly Like being close to founders, customers, and product decisions Have worked in strong start ups or fast moving product environments before Technical background matters, but mindset matters more. They're open to strong engineers from different backend ecosystems if you've built complex systems and can learn quickly. A few things worth knowing: High frequency of deployments per week Engineers use AI tooling heavily to improve speed and workflow efficiency Minimal meeting culture High trust environment with lots of autonomy Strong engineering standards without unnecessary process theatre Small team, meaningful ownership, direct impact If you're the type of engineer who likes solving hard problems with smart people, has energy & ambition, and actually seeing your work used in production by real customers, this is a very good opportunity. Send me an email at or send your CV via this ad to learn more.

Description London, UK Hybrid (3 days in our Paddington HQ: Mon, Tue, Fri) Stack: Python, Flask, SQLAlchemy, React, TypeScript, MySQL, AWS In 2018 we set out to solve a problem millions of people faced: not just struggling with their skin, but struggling to navigate skincare at all. We combined dermatology, pharmacy and technology into something simpler and genuinely personalised, and proved expert-led care could reach people who'd never had access to it. Today, +Me is the company behind Skin + Me, Hair + Me and Renew + Me , with more on the horizon. We're not building a single brand. We're building a category. We've delivered millions of treatments, we're profitable and growing fast, and we're expanding the engineering team to match. What you'll build You ll join the team behind our core commerce and clinical journey: the ecom stack, consultation engine, patient and prescription systems, and order generation. This is where customers discover us, complete a clinical consultation, subscribe, and receive their personalised treatment, at real consumer scale. On our Python and React stack, that's the storefront behind Skin + Me and Hair + Me, our flagship brands serving customers at scale. We're hiring a Senior Full Stack Engineer to own features end-to-end across this system in our Python / Flask / React stack: backend services and data models through to the customer-facing frontend, with the judgement to make sound architectural calls as we scale to more brands and more customers. What you'll do Own features end-to-end: from Python/Flask services and data schemas to the React frontend, across systems like checkout, subscriptions, and the consultation-to-prescription flow. Scale what's working: keep the platform fast, correct and resilient through new brand launches and rising volume, and make the architectural calls that keep it that way. Lift the team: clean, well-tested code and honest reviews that help the engineers around you ship with confidence. What we're looking for Depth and breadth: strong, recent, hands-on full-stack experience. You're genuinely capable across backend and frontend, not just one side. Engineering judgement: clean code, clear API design, sound data modelling, and the instinct to pick the simple, robust solution over the clever one. Shipped impact: features you owned and shipped that moved something real for customers or the business. Care where it counts: correctness isn't negotiable when your code decides what treatment a patient receives. The stack: production command of Python (Flask) and React/TypeScript; relational databases (MySQL ideal) with SQLAlchemy/Alembic; comfort with AWS and Docker. Clear communication: most of our work happens in PRs, design docs and async decisions, so writing clearly matters. Roughly 6+ years building software in production. We read for depth and shipped impact, not years. How we work We're a small, experienced engineering team working closely with product, clinical and operations. We care about craft: clean code, honest reviews, and owning what you ship through to production. And because our software turns a clinical consultation into a real prescription and a treatment someone receives, correctness and care aren't optional here. They're the job. How we use AI Agentic tools like Claude Code and Codex are a standard part of how we work, and we're leaning into them hard: we automate the routine so we can spend our energy on the harder problems. You'll need to be comfortable working this way, and real skill with these tools is a genuine advantage we value. But it's a multiplier on strong engineering judgement, not a substitute for it, and never a prerequisite. If it's newer to you and you're keen to grow, we'll back you. Compensation & benefits We pay competitive base salaries and back them with meaningful equity, so your upside grows with the company you're helping build. Equity: a meaningful stake in a profitable, Series B-backed business that's growing fast, with flexibility on your cash/equity mix. Time off: 25 days holiday plus bank holidays. Hybrid & flexible: three days together in Paddington (Mon, Tue, Fri), remote Wed/Thu, core hours 10-4 with flexibility around them. Fuelled: free breakfast and lunch on office days, plus snacks and drinks. Growth: a £500 annual personal development budget. Family & health: healthcare cash plan, cycle-to-work, and a workplace nursery scheme (save tax/NI on childcare). The extras: a dog-friendly HQ (two resident pups), an active Culture Club, and heavily discounted products for you and 10 friends & family. How we hire We keep it short and respect your time: Intro call with our engineers (25-30 mins), including a short system-design chat. A conversation with our Director of Software Engineering (30 mins). A practical take-home task, in your own time. Onsite at our Paddington HQ to review your task and meet the team. Great engineers come from all kinds of backgrounds. If this resonates, even if you don't tick every box, we'd love to hear from you. Sound like you? We'd love to hear from you.

Senior Product Engineer, Full Stack - Energy £70,000 to £95,000 Permanent London, hybrid The opportunity Our client is hiring a Senior Product Engineer, Full Stack, to help build the next generation of customer-facing software in the energy market. Operating in a complex, high-value sector, the business is combining technology, data, and product thinking to modernise an area of the energy industry that has historically been underserved by great software. We have already placed 3 people into the business and are pleased to be supporting them again on this important hire. This is a genuinely exciting opportunity for a frontend-strong engineer who wants real ownership, autonomy, and the chance to build products from scratch. They are looking for someone with strong React and TypeScript capability, alongside solid backend exposure across Python, APIs, and databases. As a Senior Product Engineer, Full Stack, you will play a key role in shaping what gets built, how it is built, and how it evolves as the business scales. For the right person, this is a chance to join a growing company at the right stage and make a visible impact. The role is based in Mayfair, London, with a hybrid setup of 2 to 3 days per week in the office. The role This Senior Product Engineer, Full Stack role has a clear frontend lean. They need someone who can build high-quality frontend products from scratch, while also working confidently across backend services, integrations, and data-driven workflows. The frontend is a central part of the brief, but they want someone who understands the wider system and can contribute beyond the UI. The product sits in a data-rich environment, with workflows across billing, metering, reporting, consumption, and asset performance.
