About the company

The company is the only broker that runs employee benefits for you. Combining health cover, pensions, protection, spend cards, and flexible perks with HRIS integrations, the company replaces spreadsheets, manual admin, and once-a-year broker calls with one connected system - backed by a team of benefits experts behind every recommendation.

The company powers benefits for more than 100,000 employees, across companies from fast-growing scale-ups to global HR and payroll platforms.

Investors include Eurazeo, EQT Ventures, Northzone, Frontline Ventures, 9Yards, and Plug and Play Ventures. The company team includes experts who previously led at global financial services firms and fintechs such as Airwallex, Stripe, Bolt, Revolut - as well as insurance and benefits providers such as Aviva, Allianz, AXA, and Smart Pension.

The role and team

We're looking for a Senior Product Engineer to join the Core and Investments team on the company Platform. The team builds the core of the platform and the financial products that sit on it. That covers products like Spend [link for members] pensions [link for members] salary sacrifice [link for members] and flexible benefits [link for members] and can stretch into areas such as health insurance [link for members] when that's where the work is.

Our teams are loosely split between Insurances and Core/Finance, and people work across both. As we add products and countries those lines will shift, so we want someone adaptable who'll own whatever matters most at the time.

This is a full stack role. Most of your time will likely be on the backend, but you'll work wherever the problem sits, including frontend when a feature needs it. We don't hire for a particular language or framework. We care far more about how you think than what you've used before.

It's an autonomous role. You'll be trusted to make product calls, not just technical ones, and we want you adding to the roadmap rather than picking up tickets.

WHAT YOU'LL DO

• Design and build the systems behind pensions, retirement savings and Spend: contributions, provider integrations, employer configuration, card issuing and wallet provisioning

• Get close to the problem before the code: find where employers and employees get stuck and turn that into clear product decisions

• Join client calls when it helps you understand a problem or explain a solution

• Own your work end to end, from scoping with the team through architecture and delivery to what happens after launch, including customer issues

• Work across the stack wherever the problem needs you, rather than stopping at the edge of one codebase

• Push back when a request doesn't match your understanding of the problem, and bring your own ideas to the roadmap

• Use AI throughout how you work: planning, building, reviewing and shipping.

• Keep what you own reliable, secure and observable, and contribute to code reviews and technical planning

• Help shape how the team works as it grows

WHAT WE'RE LOOKING FOR

• 6+ years building production software, with examples of products you've owned and improved, not just delivered

• Product judgement. You can explain the user problem, the choices you made and what changed for customers

• Full stack experience. You're comfortable going deep on the backend and can work in the frontend when the product needs it

• A track record of taking a loose brief to production, and of pushing back when something was the wrong thing to build

• Experience building dependable APIs or integrations with third-party systems. Fintech, payroll, pensions or benefits experience is a plus

• AI-native ways of working. You use AI for planning, setup and review, not just autocomplete, and you're critical about what it produces

• A clear communicator who can explain a decision to an engineer and to a customer, and knows which version each one needs

• Care for reliability, security and compliance, because people rely on what we build for important benefits

• Comfortable with pace, ambiguity and ownership in a fast-growing startup

• Ability to work to GMT hours with a 08:00 - 10:00 start

You don't need experience in any particular language or framework. Good engineers here ship to production in their first week, and the real learning curve is the product, not the stack.

WHY JOIN US

• An interesting problem. Our teams are loosely split between Insurances and Core/Finance, and people work across both. As we add products and countries those lines will shift, so we want someone adaptable who’ll own whatever matters most at the time.

• Agency. We hire people and trust them. You'll own meaningful parts of the product end to end

• Customer proximity. You'll hear directly from the people using what you build and see the impact

• Impact from day one. We're a small, focused team. What you build ships fast and matters

• AI-first. We invest heavily in AI tooling and we're not precious about token spend. If it helps you build better or faster, use it

• High standards, low bureaucracy. We care about clean design and thoughtful engineering, without the process that slows it down

OUR HIRING PROCESS

• Recruiter chat (30 mins): cover the basics and make sure we're aligned

• Introductory call (30 to 60 mins): meet one or two of our product engineers to talk through your work, how you think about product and how you use AI

• Technical interview (90 mins): a collaborative pair programming session with two of our engineers. You'll build something small against a real API, using AI tools the way you would day to day. We're looking at how you think and the product decisions you make, not speed

• Call with founders (30 mins): we'll share our vision and hear your thoughts

• Final response: we'll follow up promptly with next steps

Our Values

• Have Integrity. We care deeply about our why and it won’t jeopardise our how.

• Care Deeply. Our products are our story, we look at the details, go the extra mile to delight customers.

• Own Your Ship. Ask why, do the work, get the data, solve the problem, be an owner.

• Raise the Bar. We continuously look to push past good enough. Expect more, move faster, and never stop raising your and the team’s standards.

• Play to Win. We exist because we decided to say no to the norm – now we do this everyday.

The company Benefits

• Attractive stock options to share in the success of the company

• Health Insurance

• Life assurance (country dependent)

• Up to 5% matched contribution to a Workplace Pension (country dependent)

• WFH stipend to support your home office needs
