About the Company

We are a global technology consultancy delivering digital transformation, cloud, cybersecurity, AI, and high-performance engineering solutions to organisations across multiple industries worldwide.

Our teams work on complex, large-scale programmes that help clients modernise systems, improve services, and deliver secure, future-focused technology solutions. With an international presence and a strong engineering culture, we combine deep technical expertise with a collaborative and innovation-driven environment.

We are looking for senior engineers who enjoy architecture, system design, and end-to-end delivery, with a genuine interest in modern technologies, including AI.

About the Role

We are seeking a Senior Full Stack Engineer who is passionate about building high-quality software and designing robust systems. You will work on complex, large-scale solutions across multiple technology stacks, collaborating closely with clients and internal stakeholders.

While you will help guide other engineers, this role is engineering-led rather than people-management-focused.

This is a true full stack role, offering exposure to a broad range of technologies and architectures. You will continuously upskill while working alongside highly talented engineers, selecting the most appropriate tools and languages for each challenge.

Your Future Role

As a Senior Full Stack Engineer, you will:

• Design, build, and deploy scalable, high-quality systems
• Translate business and client requirements into technical solutions
• Work directly with clients, moving quickly from concept to production
• Lead by example through hands-on development
• Contribute to architectural decisions across multiple teams
• Support and mentor engineers while remaining deeply involved in delivery

What You Bring

• Proven experience in full stack software development
• Experience designing systems and solutions independently
• Technical leadership experience while remaining hands-on in delivery
• Strong understanding of maintainable code, systems design, and software architecture
• Experience working across multiple technology stacks
• Strong experience with strongly typed languages such as C++, Java, C#, Go, or Rust, alongside modern front-end frameworks
• Ability to adapt quickly and learn new technologies
• Interest in modern technologies including AI and cloud platforms
• Strong communication skills and confidence working with clients and distributed teams

Recruitment Process

• Online assessment (approximately 35 minutes, completed in your own time)
• Technical interview with senior engineering leadership
• Live coding session with a future colleague

All interviews are conducted remotely via Microsoft Teams.
