Remote Senior Full Stack Engineer

We’re looking for a Senior Software Engineer to join our team of 10, working primarily on our web app and workplace platform. While you’ll be frontend-leaning, you’ll also act in a tech lead capacity; designing solutions that span our entire stack, including backend services, APIs, and database models.

In this role, you’ll:

• Take ownership of end-to-end feature delivery, from shaping requirements to deployment and monitoring.
• Design technical solutions that involve both frontend interfaces and backend integrations.
• Collaborate closely with product managers, designers, and other engineers to bring new end-user features to life.
• Define and champion engineering best practices across frontend and backend development.
• Contribute to the evolution of our technical architecture as we grow our platform and user base.
• Participate in code reviews, mentor other engineers, and foster a culture of knowledge sharing.
• Help us continually improve our engineering processes, tools, and ways of working.

You’ll work across our modern, Type Script-based stack:

• Frontend:
  React (Next.js), GraphQL (Apollo), Type Script
• Backend:
  Node.js (AWS Lambda), Prisma & PostgreSQL
• Testing:
  Cypress + Jest
• Infrastructure: AWS, Terraform, CI/CD pipelines
• Practices:
  Agile, Kanban, pair programming, continuous delivery

You’ll be a great fit if you:

• Have 7+ years’ experience in software engineering, with significant experience in frontend technologies but comfortable working full-stack.
• Are highly proficient in React, Type Script , and GraphQL, with a strong grasp of backend fundamentals in Node.js.
• Have experience designing technical solutions involving APIs, database models, and service integration.
• Understand scalability, performance, and security across both frontend and backend.
• Enjoy working closely with product and design teams to build features that delight users.
• Are comfortable mentoring others and helping set technical direction for projects.
• Bonus points if you’ve worked on fintech products or complex transactional systems.

At Penfold, we’re on a mission to help everyone save enough to be comfortable in later life. We’re tackling one of society’s biggest challenges — pensions — by rebuilding the experience from the ground up and making saving simple, engaging, and accessible.

You’ll:

• Work on high-impact features used by 100,000+ savers and thousands of businesses.
• Influence the technical direction of our platform and help shape how we deliver value.
• Join a supportive, ambitious, and collaborative team where engineers have a big voice in product decisions.
