About The Position

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.

Requirements

• 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
• Feel confident contributing meaningfully from day one

• Experience with financial platforms, HR tech, or B2B SaaS
• Experience building reliable workflows with tools like Temporal

Responsibilities

• 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
