Senior Full Stack Developer

Company: Complyfirst
Apply for the Senior Full Stack Developer
Location: Northern Ireland
Job Description:

Complyfirst is a reporting automation platform for financial services compliance teams. We remove 80% of manual reporting work so teams can focus on reviewing, not doing. We grew almost 6x last year and are hiring across the business.

Role Overview

We’re hiring a Senior Full Stack Developer to work directly with our CTO. You’ll be one of the most important technical hires we make – helping architect and build the product as we scale. This role requires deep experience in PHP, Laravel, and Vue.js, and the ambition to build something genuinely world-class.

What You’ll Do

  • Architect and build. Design, develop, and maintain high-performance, secure applications. You own the quality of what ships.
  • Drive AI integration. Design and build AI-powered features that push our compliance automation further. This is a growing part of what we do.
  • Own the full stack. Front to back. You’re comfortable across the stack and don’t need to hand off to get things done.
  • Set the technical bar. Hold the standard on code quality, security, and performance. Shape the technical roadmap alongside the CTO.
  • Work across the business. Work closely with founders, engineers, and the product team. We’re small — everyone has context and everyone has a voice.

What We’re Looking For

  • 5+ years of experience. In professional software development, with strong expertise in PHP, Laravel, and Vue.js. Experience with Python or AI/ML is a plus.
  • High agency. You don’t wait to be told what to do. You see the problem, you own the fix, and you see it through.
  • Obsessed with quality. You take genuine pride in your work. You don’t ship things you’re not proud of.
  • Low ego. You’re confident in your ability but not territorial about it. You want the product to win, not to be right.
  • Technically curious. You follow where the technology is going (especially AI) and push for adoption where it moves us forward.
  • Resilient under pressure. Deadlines are real here. If you do your best work when the stakes are high, you’ll fit right in.

This Role Is Not For You If…

  • You need detailed specs before you start. Ambiguity is the default here.
  • You’re looking for a large team with established processes. We’re still building those.
  • You want to stay in a narrow technical lane. We need range.
  • You’re not interested in growing fast. We have a high bar, and we expect it to keep rising.

What We Offer

  • Competitive salary plus performance-based share options
  • Private medical and dental cover
  • Pension: 5% employer contribution
  • 35 days holiday (inclusive of bank holidays)
  • Hybrid working — 3 days in our Hillsborough, NI office
  • Company laptop
  • Outsized responsibility and growth, from day one
