An exciting opportunity has become available for a Principal Software Engineer to join a growing technology organisation in Belfast. This is an opportunity to take genuine ownership of technical direction, influence engineering practices and work on complex, business-critical software systems. Unlike traditional leadership positions, this role allows you to remain hands-on with development while helping shape how software is designed, built, tested and delivered.

What you’ll be doing
As a Principal Software Engineer, you’ll provide technical leadership across complex software platforms while remaining actively involved in development. Your responsibilities will include:
- Leading architectural decisions and defining technical standards across software systems
- Designing and developing scalable, reliable and maintainable applications
- Championing Test-Driven Development (TDD), Domain-Driven Design (DDD) and modern engineering practices
- Improving CI/CD pipelines, release processes and deployment strategies
- Working with engineers to improve system performance, reliability and observability
- Establishing coding standards, testing strategies and approaches to technical debt
- Supporting the adoption of AI-assisted engineering tools and practices
- Mentoring senior engineers and contributing to wider technical decisions

- Experience with continuous delivery, trunk-based development and automated testing
- A track record of designing and maintaining complex production systems
- Knowledge of observability, incident management and application reliability
- Experience influencing engineering standards across multiple teams or systems
- Familiarity with AI-assisted development and modern software engineering tools
- Strong communication skills and experience mentoring other engineers
Nice to have
Experience in any of the following would be advantageous:
- Developing real-time, distributed or high-availability systems
- Working with data-intensive or transaction-heavy applications
- Designing platforms that support complex business operations
- AI-enabled software delivery and automation
- Working in environments with demanding performance and reliability requirements
Why consider this opportunity?
This position offers the chance to operate at a genuinely senior technical level without stepping away from the development work you enjoy.
