Senior Backend Engineer (Golang) in London

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.

About Octopus Money: We’re on a mission to transform millions of lives by building financial resilience and wealth for everyone. Money shapes every part of life. Yet most people never get the support they need:

• Half of Brits reach retirement age without enough to live the life they want
• Financial stress is a leading cause of poor mental health
• Only 8% of people have access to 1-to-1 financial advice

There’s no shortage of information. What people actually need is clarity, guidance and a plan that makes sense for them. That’s where we come in. Octopus Money brings together financial planning, investment expertise and smart technology so people can understand their options and take action with confidence. We help people build a clear plan for their savings, investments and pensions and make investing simple with managed portfolios built by experts. We also support employers who want their teams to feel more secure and in control. Our service adapts to what each person needs. We believe everyone deserves money support that works for real life.

The role and opportunity: 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.
• Team Collaboration: 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.

About You:

• Collaborative and a great team player.
• Problem solver at heart with an analytical mindset.
• Goal-driven and not afraid to get stuck in.
• Excellent technical knowledge.

Knowledge and experience required:

• Senior expertise in software development using strongly-typed languages (e.g. Go, Java, or similar), with at least 1+ year of commercial experience using Golang.
• Product-engineering experience (e.g. solving customer problems, delivering on business goals, working with product managers and frontend teams) with Golang.
• Strong experience writing easily-testable and thoroughly-tested code.
• Demonstrable experience acting successfully as a Senior Engineer, i.e. breaking down a refined User Story into deliverable tasks and delivering those tasks within a sprint.
• Data modelling and DB design experience with SQL or NoSQL DBs.
• Distributed system and messaging event-driven architecture experience.
• Experience delivering cloud-based REST API solutions.
• Empathetic, proactive and constructive communication skills, with the ability to influence and collaborate effectively across teams.
• Able to work three days a week onsite at our London office in 33 Holborn, EC1N 2HT - #LI-Hybrid.

Nice to have (but not essential):

• SaaS knowledge and experience.
• Microservice and integrating distributed systems with messaging and event-driven architectures.
• AWS Architecture experience.
• Experience using Terraform, or other infrastructure as code tooling.
• Educated to Bachelor's or Master's degree level in Computer Science, Engineering, or a related field.

In return we offer a base salary of £75,000 to £95,000 DOE + benefits. We want people to grow here, to feel supported and to feel proud of the impact they make. You’ll get:

• Hybrid working with 2 days at home each week (Monday and Friday).
• 18 days a year working from anywhere (for non-regulated roles).
• Being part of Octopus we benefit from the group share incentive plan. In addition, for those who are not commission based we offer a team bonus provided we meet our team goals.
• Company pension.
• Private medical insurance.
• Enhanced parental leave.
• Birthday day off.
• A supportive team who care about what they do.
