Full Stack Software Developer

MCS Group is delighted to be partnering with a brand new FDI as they build out a new team here in Belfast. Our client is a high-growth cloud and data engineering consultancy. They are seeking a full stack software engineer to join their team. This organisation delivers mission-critical cloud, API, and data solutions for enterprise and high-growth clients, embedding directly within client teams to build scalable, production-grade systems.

The Role

As a Full Stack Engineer, you'll work across both frontend and backend systems, contributing to the design and delivery of robust, data-driven applications. This is a hands-on role suited to someone who enjoys solving complex problems, influencing architecture, and working in a collaborative, high-performing team.

Day-to-day responsibilities:

• Deliver high-quality features across the full stack, from UI to backend services
• Contribute to architectural discussions and technical design decisions
• Build scalable APIs and data-driven services
• Work with streaming/event-based systems in production environments
• Improve system reliability, performance and maintainability
• Collaborate closely with cross-functional stakeholders and client teams
• Mentor peers and contribute to engineering best practices

What you need:

• Strong experience in full stack engineering
• Solid Java or Python development experience
• Exposure to React or similar front end framework
• Experience working with large datasets and strong SQL capability
• Familiarity with cloud-based environments and CI/CD workflows
• A proactive mindset and comfort operating in high-ownership environments

Experience in regulated or performance-sensitive industries would be advantageous but is not essential.

What's in it for you:

• The chance to join during an exciting growth phase
• Meaningful technical ownership and influence over design decisions
• Exposure to complex, enterprise-scale systems
• Hybrid working model
• Competitive salary and comprehensive benefits
• A collaborative, growth-focused engineering culture that values initiative
