Senior Backend Engineer; Golang Holborn

We’re looking for a Senior Backend Engineer with excellent Golang and database skills to help us build the scalable operations, technology, and processes needed to transform 5 million lives by making high-quality financial support affordable and accessible to employees everywhere.

This is an ideal opportunity for a motivated self‑starter to accelerate their career, taking a broad and varied role within a rapidly growing company. We pride ourselves on building an inclusive working environment where diversity is celebrated.

At Octopus Money, we’re on a mission to make money advice accessible to all – because the right advice can turn your life dreams into reality.

The facts are alarming: half of Brits reach retirement age without enough money to live the life they want, financial stress is a leading cause of poor mental health, and only 8% of us have access to 1‑to‑1 advice.

There’s plenty of information out there, but most of us just wish that someone we trust would tell us what to do with our money!

With Octopus, you get a personalised plan and a friendly expert to help you make it happen. We combine advisers, coaches, and technology to understand your situation and recommend the right steps for your savings, investments, pensions and more. Then, we make it easy to invest in a custom portfolio, managed by experts.

We believe everyone deserves personal, 1‑to‑1 advice with their money.

As a Golang Backend Engineer, you will be working within one of our multi‑disciplinary feature squads to design and implement new capabilities. You will be expected to improve the code quality and provide well‑tested functionality that the business can depend on for success. Our API service layer is written in Go, following a documentation‑first mindset. We use a service‑oriented architecture to enable extensive unit testing with generated mocks.

Our services are deployed via a CI/CD pipeline to our AWS cloud environments.

You will be responsible for:

• Code Development and Review
  • Demonstrate excellent Go development skills, with the ability to write high‑quality, easily testable code
  • Take refined User Stories and break them down into development sub‑tasks
  • Champion software engineering best practices, including automated tests, code refactoring, and code reviews where appropriate
  • Ensure adherence to coding standards, security guidelines, and compliance requirements
• Collaborate with cross‑functional teams to translate business requirements into technical solutions, working closely with Product Owners
• Technical Strategy
  • Contribute to the development of technical roadmaps and long‑term strategies, aligning with business goals
  • Stay updated on industry trends and emerging technologies, identifying opportunities for innovation and improvement

Collaborative and a great team player – We’ve built a great team of top performers, and you’ll need to work with others from across the business to identify problems, agree solutions and implement changes.

Problem solver at heart with an analytical mindset – You should be someone who gets excited by complex problems and can find creative ways to solve them no matter what your level of knowledge and experience with the subject matter.

Goal‑driven and not afraid to get stuck in – We like to set brilliant goals and find creative ways to hit them, even if that means rolling up our sleeves and doing manual tasks before we’ve managed to fully automate them. You should have a bias towards action and getting things done.

Excellent technical knowledge – As a Senior Backend Engineer, you should be an expert in at least one aspect of software development and skilled in other areas. You have learned that delivering great software takes a team and has plenty of pitfalls to avoid.

• Product‑engineering experience (e.g. solving customer problems, delivering on business goals, working with product managers and frontend teams) with Golang.
• Strong experience writing…
