We're working with a fast-growing SaaS company operating at the intersection of data, enterprise platforms, and security. They're building a highly sophisticated product used by large-scale organisations to make smarter, data-driven decisions across complex systems.
They're now looking to bring in a Senior / Principal Full Stack Engineer to play a key role in shaping the product and technical direction as they scale.
This is a hands-on role with real ownership, ideal for someone who enjoys building high-quality systems, influencing architecture, and working closely with product.

Tech Stack
- Backend: Java, Spring Boot (Data, Security, MVC)
- Frontend: Vue.js
- Cloud & DevOps: AWS, CI/CD pipelines
- Data: SQL, database design & optimisation
- Architecture: RESTful APIs, scalable system design
What They're Looking For
- Strong experience in Java + Spring Boot at a senior level
- Deep expertise in Vue.js and modern frontend development
- Proven experience building scalable, production-grade systems
- Solid understanding of API design, databases, and cloud environments
- Ability to take high-level requirements and break them down into technical delivery
- Experience mentoring engineers or leading technical projects
Nice to have:
- Exposure to cybersecurity, data platforms, or complex enterprise systems
Why This Role?
- Genuine ownership and impact on product direction
- High-calibre engineering environment
- Equity as part of the package
