In this position, the Senior Backend Engineer will play a central role in building and scaling mission-critical, data-heavy applications. You'll be involved across the full engineering lifecycle - from system design through to development and delivery - taking ownership of solutions that drive real impact.

Working closely with an Engineering Manager and collaborating with cross-functional teams, the Senior Backend Engineer will help shape and implement microservices-based architectures, while making use of modern technologies such as AWS, Kubernetes, Docker, and Kafka. You'll also focus on improving performance, reliability, and scalability, contributing to design discussions, code reviews, and knowledge sharing across the team.

Senior Backend Engineer - Key Skills & Experience:

Strong background in backend software engineering, with significant commercial experience
Advanced proficiency in Python or Java, with hands-on expertise in AWS, Kubernetes, and Docker
Experience designing and architecting systems end-to-end
Proven track record of working with complex, large-scale data applications
Product-driven mindset and experience working in fast-moving, tech-focused organisations (e.g. start-ups or scale-ups)
Additional skills with Kafka, Cassandra, gRPC, and microservices design are highly advantageous
Open-source contributions are a plus

This is an excellent opportunity for a Senior Backend Engineer who thrives on tackling technical challenges and wants to make a tangible impact. The client is looking to move quickly, so if this sounds like the role for you, don't hesitate to apply.

We are an equal opportunities employer and welcome applications from all suitably qualified persons regardless of their race, sex, disability, religion/belief, sexual orientation, or age.
