Lead Engineer - Personal Savings
Confirmed on the employer's own hiring board on Nov 3, 2026. First seen by Alion on Oct 23, 2026.
ABOUT US
At OakNorth, we're on a mission to empower ambitious businesses and the communities they serve. Since 2015, we've lent over $21 billion across the UK and US, helped create more than 58,000 new homes and 36,000 new jobs, and supported hundreds of thousands of personal savers - all while driving economic growth in the markets we serve.
About the team
Personal Savings and Wealth exists to make saving simple, personal and rewarding, helping families build financial confidence from everyday savings to long-term plans.
We own the full product lifecycle, from spotting customer needs and shaping propositions through to design, build, launch and growth. That means the end-to-end experience across mobile and web, the secure, resilient systems behind it (money movement, identity and customer servicing), and working closely with marketing, operations and commercial teams to take products to market and measure what lands. We’re constantly improving our core savings products while bringing new ones to life, combining thoughtful design, strong engineering and a sharp commercial focus.
The role
Lead multiple AI-native pods while staying hands-on: coding, reviewing and pairing.
Manage stakeholders at every level, from product and commercial to risk and senior leadership, setting expectations and negotiating trade-offs.
Turn customer and business needs into products that land, bringing stakeholders with you from idea to launch.
Own technical delivery and measure success by business impact, not lines of code.
Design simple, resilient, scalable event-driven systems: you build it, you run it.
Break complex problems into incremental, shippable steps with clear domain boundaries.
Shape platform-wide architecture with an eye on wider business impact.
Coach and mentor engineers by example.
Use GenAI to move faster and decide better and help set the direction for how it’s embedded across the organisation.

Python, NodeJS
TypeScript, React, styled components

How we expect you to work
We expect you to work in these ways, as well as encouraging and enabling these practices from others:
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, can 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.
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
