Senior Fullstack Engineer - Payments

Senior Fullstack Engineer - Payments

OakNorth is a profitable business that has supported the growth of thousands of entrepreneurs with a new standard of business lending. 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.

Team Mission Payment's mission is to deliver a fast, reliable, and seamless payment experience that empowers our customers to move money effortlessly and securely. We own the full payments journey, from transaction initiation in the mobile and web frontends to the processing in the backend, including Fraud and AML checks and connecting to the payments schemes, ensuring that businesses can focus on growth while we handle the complexity behind the scenes.

The Role

• 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

Technology

• 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

How We Expect You To Work

• 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.

How We Expect You To Behave

• We embrace difference and know that when we can be ourselves at work, we are happier, more motivated and creative. We want to be able to bring our whole selves to work, have our own perspectives and know that we belong. As such, through your behaviours at work, we expect you to reflect and actively sustain a healthy engineering environment that looks like this:
• A wide range of voices heard to the benefit of all
• Teams that are clearly happy, engaged, and laugh together
• Perceivable safety to have an opinion or ask a question
• No egos - people listen to and learn from others at all levels, with strong opinions held loosely

What Makes Working Here Better

• This is a truly hybrid role, offering engineers the flexibility to work from home while also providing opportunities to collaborate in person with the team when it adds value. There's no fixed requirement for days in the office, instead, we focus on creating space for engineers to engage meaningfully, whether that's in-person for whiteboarding sessions or remote for deep focus work.
• Work-life balance - 25 days holiday (plus bank holidays) each year, and enhanced family leave allowances.
• Competitive salary & equity - We want people to have a serious stake in the business.
• Good kit - Your choice of the best laptop, running macOS or Ubuntu.
• Team socials - The opportunity to get to know each other outside of work.
• Company socials - A chance to catch up and meet new colleagues weekly over informal office breakfasts and dinners on OakNorth - or at our free barista bar every day.
• Commuter support - We offer the cycle to work & EV scheme.
