About the job

This role is being recruited for by Vecta, on behalf of one of our partner companies.

Full Stack Developer

Location: Northampton, UK (Hybrid - must be within commutable distance)

Contract: Permanent, Full-Time

Salary: £60,000 - £70,000 + Uncapped Annual Bonus (typically 5% - 15%)

The Opportunity

Our client is a privately owned, high-growth UK finance group that has funded over £1.5 billion for 20,000+ SMEs. Having more than doubled in size in recent years, the business is investing heavily in custom software, automation, and AI, and is looking for a Senior Full Stack Developer to lead that build.

This is a hands-on role with real ownership. You'll build full-stack applications end-to-end - React frontends, Python and Node.js backends, deployed on AWS (Lambda, Amplify, Cognito, Athena, S3, Redshift) and Zoho Catalyst. Your code goes live, gets used across the business daily, and directly supports hundreds of millions of pounds in lending.

What You’ll Do

• Build, deploy, and maintain full-stack web applications, internal platforms, and business tools.
• Design and run cloud-native solutions across AWS and Zoho Catalyst, including secure authentication with Cognito.
• Build reliable API integrations between Zoho CRM, AWS applications, lender platforms, and third-party services.
• Work with the ML and data teams to embed predictive models and automation into live workflows.
• Champion modern engineering practice: testing, CI/CD, code review, documentation, and secure deployment.
• Use AI-assisted development tools (Codex or similar) to move faster, while keeping strong engineering judgement.

What You’ll Bring

• 5+ years of commercial full-stack development experience.
• Excellent Python, plus strong JavaScript/React and Node.js - building production APIs, services, and frontends.
• Proven hands-on AWS experience (Lambda, EC2, Cognito, Athena, S3, Redshift, or similar).
• Experience shipping and maintaining secure, business-critical cloud applications and API integrations.
• Strong fundamentals: SQL, Git, testing, security, and maintainable code.
• Clear communicator who works well with technical and non-technical teams alike.

Nice to have: Zoho CRM/Catalyst or Deluge scripting, and experience in lending or FinTech.

Why This Role

• Your work runs the daily operations of a business lending hundreds of millions of pounds.
• Modern AWS-first stack, an AI-forward engineering culture, and the freedom to shape how it evolves.
• £60,000 - £70,000 plus uncapped annual bonus, with 3-4 days a week at the Northampton HQ.
