We work with ambitious clients to help them solve their biggest business and customer challenges. We help our clients to innovate and create intelligent digital products and services. We thrive on complex  challenges and deliver business-critical IT transformation projects, moving seamlessly from strategy, design and delivery to operations.

This is a Hybrid role, offering the flexibility to balance your professional and personal life, with 2 days a week spent connecting with colleagues in  our London office or on client site.

As a Senior Backend  Developer, you will be a vital technical pillar within your squad. You will design and deliver end-to-end features and subsystems, ensuring our codebases remain modular, reusable, and scalable.

Beyond code, this role is deeply collaborative. If you enjoy lifting others up, mentoring junior colleagues, and bringing empathy to technical problem-solving, you will find a highly rewarding home here.

In this role you will be involved in:

• Design, build, and deliver scalable, secure backend services and applications.

• Architect end-to-end backend solutions using modern cloud-native and microservices-based approaches.

• Write clean, maintainable, and reusable code with a strong focus on quality, performance, and reliability.

• Champion engineering best practices through code reviews, mentoring, and knowledge sharing.

• Define and promote effective testing strategies across unit, integration, and service-level testing.

• Build resilient, scalable, and production-ready systems.

• Collaborate effectively with cross-functional teams to deliver high-quality solutions.

• Communicate technical decisions and articulate trade-offs to both technical and non-technical stakeholders.

• Support the growth of junior engineers through coaching, feedback, and pair programming.

• Balance delivery pace with technical quality, enabling teams to make informed engineering decisions.

• Contribute to the continuous improvement of engineering practices by sharing ideas, lessons learned, and emerging technologies.

• A passion for clean code, engineering best practices, and continuous improvement.

• Strong communication skills, with the ability to explain technical concepts to both technical and non-technical audiences.
