About the Company: GT Maritime provides mission‑critical maritime cybersecurity and communications software to 2,000 companies and 16,000 vessels worldwide — roughly a quarter of the world's non‑navy fleet. Based in Warrington, UK, GT Maritime operates as a focused, technically rigorous business with a strong culture of quality and long‑term ownership.
About the Role: Reporting to the Head of Engineering, this Full Stack Developer role sits at the centre of GT Maritime's next phase of product development. The team is building the next generation of GT Maritime's platform — the layer where customers see what is happening across their entire fleet. This hire will design and build partner API integrations across the cybersecurity stack — endpoint protection, network security, user awareness training, and SIEM/SOC tooling — and set the standard for test‑driven development across the codebase. This is a hands‑on, permanent role.
Responsibilities:
- Design and build partner API integrations across GT Maritime's cybersecurity stack — endpoint protection, network security, user awareness training, and SIEM/SOC tooling.
- Write clean, modular, well‑tested code following object‑oriented design principles.
- Participate in code reviews and hold a high bar for what ships.
- Work within six‑week Shape Up build cycles, collaborating with the Head of Engineering and Product on scoping, requirements, and effort estimation.
- Use AI‑powered development tools (Claude Code, Cursor, GitHub Copilot) as standard instruments throughout the development workflow.
- Champion and model TDD practice across the team — write tests first, every time, and make that standard infectious.
- Own test coverage, regression strategy, and acceptance criteria validation for integration code.
- Contribute to post‑release reviews and continuous improvement of the delivery process.
- Promote secure coding practices and conduct security‑focused code reviews aligned with ISO 27001 certification.
- Support vulnerability identification and remediation as part of the everyday development workflow.
- Enforce least‑privilege access and secure infrastructure configuration across the integration layer.
- Work alongside DevOps to understand and contribute to CI/CD pipelines, AWS resource management, and deployment practices.
- Support monitoring, logging, and alerting improvements that help the team detect and resolve issues faster.
Qualifications:
- Full Stack Development — 3+ years of hands‑on commercial experience building and shipping features in a SaaS environment.
- C# / .NET Core is the core backend language.
- Vue.js with Nuxt 3 is the front‑end framework.
- API Integration — Proven experience with REST, OAuth2, webhooks, rate limiting, and retry patterns.
- Has integrated with third‑party commercial APIs at production scale.
- Cloud & DevOps — Familiar with AWS (EC2, RDS, Lambda, S3) and CI/CD pipelines.
- Comfortable with microservices and distributed processing architectures.
- AI‑Assisted Development — Comfortable using AI‑powered development tools as everyday instruments.
