Company mission
To serve and empower businesses in the Missing Middle, ensuring each and every one of them has the right tools, insights, and support at every stage of their growth journey with us.
Role
Who you are
- Collaborate 💬 - We work in cross-functional, mission driven, autonomous squads that gel over time. We pair program to work better through shared experience and knowledge
- Focus on outcomes over outputs ✅ - Solving a problem for users that translates to business results is our goal. Measurements focused on that goal help us to understand if we are succeeding
- Practice continuous improvement 💡 - We optimise for feedback now, rather than presume what might be needed in the future and introduce complexity before it will be used. This means we learn faster. We share learnings in blame-free formats, so that we do not repeat things that have failed, but still have confidence to innovate
- Seek to understand our users 👂 - We constantly seek understanding from data and conversations to better serve our users' needs, taking an active part in research to hear from them directly and regularly
- Embrace and enable continuous deployment 🤖 - Seamless delivery of changes into an environment - without manual intervention - is essential for us to ensure that we are highly productive; consider resiliency; and practice security by design
- Test outside-in, test first - TDD keeps us confident in moving fast, and deploying regularly. We want to solve user problems, and so we test with that mindset - writing scenarios first, then considering our solution; coupling tests to behaviour, rather than implementation
- You build it, you run it ⚙️ - We embrace DevOps culture and end-to-end ownership of products and features. Every engineer, regardless of their role, has the opportunity to lead delivery of features from start to finish
- Be cloud native ☁️ - We leverage automation and hosted services to deliver resilient, secure services quickly and consistently. Where SaaS tools help us achieve more productivity and better quality results for a cheap price, we use these to automate low value tasks
What the job involves
- We're looking for a Senior Fullstack Engineer to join our engineering team in building upon this success, as we grow to play a key part in redefining the future of business banking with next generation financial tools and products
- Have a strong technical background, including 5+ years of experience designing and engineering large-scale systems
- Measure your success in terms of business impact, not lines of code
- Internalise the best ideas from across the organisation, humbly setting a vision that others can get behind
- Embrace DevOps culture: You build it, you run it
- Work well cross-functionally and earn trust from co-workers at all levels
- Care deeply about mentorship and growing your colleagues
- Prefer simple solutions and designs over complex ones
- Enjoy working with a diverse group of people with different areas of expertise
- You challenge the existing approach when you see the cliff edge racing towards us, but also get on board once the options have been debated and the team has made a decision
- You're a broad thinker and have the capability to see the potential impact of decisions across the wider business
- Utilise GenerativeAI: Leverage GenAI tools to increase productivity and enhance decision-making processes within the role
- It would be an added bonus if you have experience with/ knowledge of transaction monitoring, financial crime prevention, AML, and fraud detection
- Nice to have - Familiarity with transaction systems, statements, and reconciliation processes
- We're pragmatic about our technology choices. These are some of the things we use at the moment:
- 🗃 Python
- 🗄️ PostgreSQL, BigQuery, MySQL
- 🎨 TypeScript, React, styled-components
- 🔧 Jest, React Testing Library, Cypress, pytest
- ☁️ AWS, GCP
- ECS Fargate, Docker, Terraform, GitHub Actions

Our take
The cost-of-living crisis has put pressure on small and medium-sized businesses, making it harder for them to access the financing they need to thrive. And traditional banks often overlook these businesses, leaving a gap in the market for tailored financial solutions.
OakNorth is filling this gap, with its digital bank that provides loans to lower mid-market businesses. By leveraging advanced technology and data analytics, it offers better lending solutions compared to traditional banks.
Its impact is growing too. As of early 2025, it surpassed $1B in lending to US businesses since launching operations there in mid-2023. This is a huge milestone and one that reflects the demand for its services. With this success, the company is in a great position to continue expanding and helping even more businesses achieve their growth objectives.
