Job description

We're a finance company building and running our own B2B application to manage both our internal operations and our relationships with external partners. The platform sits at the centre of the business, handling the flow of finance applications from initial enquiry through to approval, underwriting, payout and ongoing customer communication.

It's used day-to-day by our team, as well as dealers and lenders we work with, to track and manage applications in real time. The system brings together multiple data sources and third-party providers into one place, helping us process applications efficiently, stay compliant, and scale our operations.

From a technical perspective, the platform is a modern web and mobile system, but at its core it exists to support a practical, commercial goal: getting finance deals processed quickly, accurately and in line with regulation.

This role gives you exposure to a live business-critical system, where the work you do directly impacts real customers, real applications and real revenue. You'll be contributing to something that isn't theoretical - it's used every day to run the company.

You'll join the development team as a Junior AI Programmer & QA Tester - a hybrid role splitting roughly 50/50 between coding and QA testing across web, mobile and API platforms.

What you'll be doing:

AI-assisted programming

  • Use AI coding tools to deliver features, fixes and refactors across the stack

  • Build integrations with third-party providers (finance, identity, communications)

  • Contribute to admin tooling and customer-facing features

  • Review AI-generated code critically

QA & test engineering

  • Own manual testing across web, iOS and Android

  • Write and maintain structured test plans

  • Test integrations end-to-end

  • Validate compliance (FCA / GDPR)

  • Maintain Postman collections and automation scripts

Requirements

Foundation in software development

  • JavaScript / TypeScript/ PHP knowledge

  • React and Node.js familiarity

  • Understanding of APIs and QA practices

  • Experience using Git

Nice to have

  • Mobile app experience

  • Testing tools (Postman, Cypress, Playwright)

  • CI/CD exposure

  • LLM API usage

What we're looking for

  • Curious and analytical

  • Detail-oriented

  • Strong communicator

  • Pragmatic

  • Coachable

Benefits & conditions

Competitive salary (£32,000 - £40,000) Experience Depending

  • Hands-on mentorship

  • Exposure to modern AI tooling

  • Career progression opportunities

Pay: £32,000.00-£40,000.00 per year

Benefits:

  • Casual dress
  • On-site parking
