About the Role

Were scaling a high-growth software business transitioning from ScaleUp mode into a structured, customer-delivery focused organisation.

Their customers include large, globally recognised organisations, and the work sits at the intersection of advanced technology and real-world application. As the company scales, it is building a team that combines strong engineering fundamentals with a delivery mindset.

The Opportunity

Were hiring multiple Software Engineers (Full Stack) across levels (Junior, Mid, Senior) to help build and deliver production-grade systems used by major enterprise customers.

This is a full stack role, but with an emphasis on backend engineering. Youll be working on scalable, distributed systems where backend capability is critical, alongside modern front-end development.

This is an opportunity to work on meaningful, complex systems in a fast-evolving environment where engineers take ownership, influence decisions, and directly impact delivery outcomes.

What Youll Do

  • Build and maintain scalable applications across front-end and serverless back-end systems
  • Collaborate closely with product, delivery, and specialist engineering teams
  • Contribute to system design and architectural decisions
  • Deliver features end-to-end from concept through to production
  • Participate in code reviews and continuously improve engineering practices
  • Have the opportunity to join customer discussions to better understand requirements and constraints
  • Operate effectively in a fast-moving, evolving delivery environment

Tech Stack

  • Backend: Python and/or Node.js
  • Frontend: TypeScript, Vue.js (with an internal component framework)
  • Cloud: AWS (serverless architecture Lambda, API Gateway, async/queue-based systems)

What Were Looking For:

Core Requirements

  • Experience building full-stack applications, with strong backend capability
  • Backend experience with Python or Node.js (essential)
  • Strong understanding of modern JavaScript/TypeScript ecosystems
  • Good understanding of systems thinking and how services interact end-to-end

Highly Desirable

  • Experience with AWS, particularly serverless architectures (Lambda, API Gateway, event-driven systems)

Mindset & Culture Fit (Critical)

  • Comfortable operating in a startup/scale-up environment
  • Energised by ownership, impact, and ambiguity
  • Willing to collaborate cross-functionally, including occasional customer interaction

Nice to Have

  • Exposure to regulated or high-compliance environments
  • Experience working with distributed teams
  • ML experience
  • Awareness of AI tools, with a pragmatic understanding of constraints

Working with Them

  • Hybrid working model based in Belfast
  • Small, collaborative teams with high ownership
  • Opportunity to shape systems and ways of working as the organisation scales
  • Work on impactful projects with well-known global customers

Theyre hiring across the business, so if this one isnt for you still get in touch!
