Position: Software Engineer, Full Stack
Location: Belfast
Team: Activity Monitor

The Role

We are seeking a Lead Software Engineer (Full Stack) to provide technical leadership across a TRG Screen product team. This is a hands-on role combining deep engineering expertise with ownership of technical direction, architecture, and delivery — working within a .NET-based full-stack environment that blends new feature development with improving and modernising complex, established systems. TRG Screen is an AI-driven engineering organisation, and this role is expected to champion that culture — setting the standard for how the team builds with AI and leading by example.

Responsibilities

Technical Leadership

Lead technical vision and architecture across the team — own decisions on technology stack, design patterns, and system design.
Establish and enforce coding standards, best practices, and development processes.
Champion and role-model AI-assisted development across the team — driving adoption of AI tooling, spec-driven workflows, and responsible use of code-generation practices.

Development & Delivery

Design, develop, and own complex full-stack initiatives, setting the standard for code quality and craftsmanship.
Conduct rigorous code reviews, providing constructive feedback and ensuring adherence to clean code principles and design patterns.
Champion automated testing practices and ensure system reliability, performance, and security through proactive monitoring and optimisation.
Troubleshoot and resolve the most challenging technical issues, identifying root causes and implementing sustainable fixes.

Team Leadership & Collaboration

Mentor and provide technical oversight for engineers, supporting their growth through guidance, code reviews, and unblocking.
Build team capability through pairing, training, and documentation standards.
Partner with Product Management to translate requirements into realistic technical solutions and timelines.
Communicate technical decisions clearly to technical and non-technical stakeholders; contribute to sprint planning and continuous improvement.

Required Skills and Qualifications

8+ years of professional software development experience, with strong expertise in C# and .NET Core.
3+ years in a technical leadership or senior engineer role, with a track record of mentoring engineers and owning technical direction.
Strong knowledge of JavaScript and TypeScript, with experience in modern front-end frameworks (React, Angular, or similar) for building data-driven UIs.
Deep understanding of software design principles with proven ability to make and document architectural decisions in large, complex codebases.
Strong database skills with relational databases (SQL Server or PostgreSQL preferred).
Proven track record of implementing comprehensive testing strategies and owning system reliability, performance, and security.
Excellent communication skills and strategic thinking — able to influence technical decisions, work effectively with Product, and balance technical debt against delivery.

Preferred

Experience with desktop agent or endpoint monitoring software.
Familiarity with CI/CD pipelines and DevOps practices
Hands-on experience with cloud platforms such as AWS or Azure.
Experience with AI-assisted development tools (e.g., Claude Code, Cursor) as part of day-to-day engineering practice — this is how we build at TRG Screen.
Familiarity with spec-driven development — using structured specifications to guide AI coding agents, preserve architectural intent, and validate generated output (e.g. BMAD, GitHub Spec-Kit).
