- Take ownership of technical delivery and help shape the future engineering culture of the Belfast team
What you'll bring
- Strong commercial software engineering experience in large-scale production or enterprise environments
- High proficiency in at least one core backend language such as Java or Python
- Experience building scalable backend systems, APIs, and modern applications
- Exposure to TypeScript/Node.js or a strong willingness to work with and learn modern TypeScript technologies
- Experience working with cloud platforms such as Google Cloud Platform, AWS, or Azure
- Strong understanding of software architecture, engineering best practices, and scalable system design
- Comfortable working autonomously and taking ownership in a fast-moving environment
- Strong communication skills and experience working directly with stakeholders or clients
- Experience mentoring others or an interest in progressing into team leadership would be highly desirable
Nice to have
- Experience with React or modern frontend frameworks
- Exposure to GraphQL APIs
- Experience with Terraform, Docker, or infrastructure-as-code tooling
- Familiarity with data engineering, analytics, or AI/ML-driven systems
What's in it for you
- Join at an early stage of a fast-growing engineering consultancy
- Opportunity to become a foundational hire within the Belfast team
- Work on large-scale, enterprise-grade cloud and AI projects
- Gain exposure to cutting-edge technologies across cloud, data, and AI engineering
- Clear progression opportunities into technical leadership or management
