Java Technical Lead

We are seeking an experienced Java Technical Lead to join our UK Digital Data & Cloud Practice.

• Maintain clear awareness of team activities, workload distribution, and developer challenges.
• Communicate status, risks, and expectations effectively to both Version 1 and client stakeholders.

• Experience working on trading or financial platforms that process millions of messages per day, with strong awareness of related non-functional requirements such as latency, resiliency, throughput optimization, failover handling, and backpressure management.
• Experienced in designing and developing cloud native applications with a microservices architecture running on Docker/OpenShift/Kubernetes platform.
• Experienced in application development using Java, SQL (SQL server, Oracle etc) and Messaging Platforms such has Kafka, MQ etc.

At Version 1, we believe in providing our employees with a comprehensive benefits package that prioritises their well-being, professional growth, and financial stability. 

One of our standout advantages is the ability to work with a hybrid schedule along with business travel, allowing our employees to strike a balance between work and life.
