Our technology is the link that connects the entire benefits ecosystem, creating better outcomes for employers, employees, brokers, and providers. Our mission is clear: we're here to create a world where everything operates at its very best, ensuring that every employee receives the support they need to live life to the fullest, both at work and beyond. ## YOUR MISSION As a backend leaning Full-stack Engineer at Ben, you’ll help build and scale the features that power our platform from benefits browsing and payments to provider integrations and smart admin tooling. You’ll take features from idea to production: understanding the problem, scoping solutions, building, shipping, and making sure what you deliver truly solves the need. You won’t just be handed tickets, you'll contribute to shaping why we build things, how we build them, and what the future of our product looks like. You’ll collaborate across product, design, and engineering to make decisions that matter: data models, integration patterns, API design, scalability choices, and how we support a system used by hundreds of thousands of people. At Ben, everything is connected so what you build helps power payroll workflows, provider integrations, notifications, and everything in between. And you’ll do all this as part of a fun, fast-moving startup, spending 2 days a week with the team in our Barbican office. ## THINGS YOU WILL BE WORKING ON… - Build and ship backend-leaning fullstack features across the product (APIs, services, integrations, and React frontend) - Are pragmatic and can balance shipping fast with thoughtful engineering - Work closely with product managers to understand context and shape solutions early - Collaborate with designers to create polished, intuitive experiences - Contribute to technical discovery, architecture thinking, and implementation planning - Ask product and UX questions when something doesn't quite add up - Design with scale, reliability, and enterprise readiness in mind (security, compliance, flexibility) - Own your work from idea to production and care about the impact once it’s live - Help improve developer experience, tooling, and internal standards - Ensure security best practices (OWASP, AWS Well-Architected, etc.) are embedded in how we ship software YOU WILL THRIVE IN THIS ROLE IF YOU… - Have strong experience building modern web apps, especially backend systems - Are comfortable in Python and TypeScript (or excited to learn quickly) - Care about solving real user problems, not just closing tasks - Enjoy collaborating directly with PMs and designers without needing perfect specs - Like figuring out the how with autonomy and the why with curiosity - Know what it means to build for enterprise scale - Are pragmatic able to balance scrappy shipping with thoughtful engineering - Communicate clearly and enjoy working with friendly, ambitious people ## NICE-TO-HAVES, BUT NOT DEAL-BREAKERS: - Experience with financial platforms, HR tech, or B2B SaaS - Experience building reliable workflows with tools like Temporal YOU WILL NOT LOVE THIS ROLE IF YOU… - Prefer a slow or highly predictable pace we move quickly and value action - Feel uncomfortable owning projects end-to-end and being accountable for outcomes - Prefer maintaining the status quo we challenge assumptions and improve constantly - Want a heavily structured environment we’re still building processes as we grow - Struggle with ambiguity or prefer prescriptive direction you’ll get context, but you’ll need to figure things out - Wait for others to take initiative this is a proactive, high-performance team Not sure if you meet 100% of the requirements? That’s okay, careers aren’t linear. If you have a strong technical foundation, solid backend experience, and enthusiasm for fullstack engineering in a fast-moving startup, we’d love to hear from you. Just make sure you feel confident contributing meaningfully from day one. ## OUR COMPENSATION & BENEFITS It’s important to us to practise what we preach when it comes to our benefits.

It replaces fragmented, multi-system approaches with one programme across every market, offering local flexibility built in. Features include an eligibility rules engine, multi-entity configuration, regional policy management, payroll reconciliation, global spend dashboards, segmented utilisation reports, and CFO-ready exports. - **Ben Allowance**: A flexible benefits perk for employees, providing a monthly allowance (starting at £100, increasing with tenure up to £250 per month) to spend on whatever benefits they choose. - **Data & Insights Module**: Provides live data on programme cost, delivery, and utilisation — designed to give CFOs and HR leaders actionable analytics without manual spreadsheet work. - **Mobile-first Employee Experience**: A mobile-first interface that gives employees clear, plain-language access to their benefits on any device, with no corporate email required. ## Market Standing - **Valuation/Market Cap**: Not publicly disclosed - **Key Metric**: Raised $16M in Series A funding; manages tens of millions in benefits spend for customers across 140+ countries - **Notable Investors/Partners**: Not explicitly named in source materials, but the company is ISO 27001:2022 certified, GDPR compliant (as both data controller and processor), and holds Cyber Essentials, FSQS, and NIST CSF + CIS certifications. The platform supports SSO via SAML 2.0 and OIDC. - **Growth Signals**: The company has grown from 11 customers and 10 employees (2021) to 113 customers and 46 employees (2023), and then to 162 customers, 93 employees, and over 50,000 users (2024).
