Principal Software Engineer (Java)

As a Principal Software Engineer, you’ll contribute directly to embedding AI across workflows, including delivery, product, and strategy. You’ll help accelerate client outcomes through our AI Accelerator and play a hands-on role in the evolution of tools like TestPilot AI, which uses natural language and generative intelligence to automate mobile and web testing.

You’ll also have the opportunity to take part in client-facing AI workshops, where we explore real-world applications of generative AI and collaborative innovation. If you’re excited by the power of applied AI, this is your platform to lead.

Design and implement distributed systems using Java Spring Boot, REST APIs, and cloud-native tooling

Architect microservices that are resilient, scalable, and fault-tolerant using Kafka or RabbitMQ for messaging

Define and enforce patterns for Event Sourcing and Command Query Responsibility Segregation (CQRS)

Collaborate with product and engineering teams to translate business requirements into scalable system designs

Ensure infrastructure and application layers conform to Zero Trust principles and enterprise security models

Deploy and manage containers using Kubernetes, and orchestrate APIs via API Gateways (Kong or similar)

Work with data teams to model and manage schemas on Oracle and integrate with existing enterprise systems
