This role is part of our Digital Platform Services team, who are responsible for delivering central services to the divisions in an API first way by utilising AI to pioneer of AI-first development practices.


Tasked with building modern, scalable software solutions using cutting-edge AI tooling to demonstrate what's possible when AI is deeply integrated throughout the entire development lifecycle (SDLC/PDLC).

Your role in the Team's Success

===================================

As a senior engineer, you'll be a hands-on contributor focused on delivery. You'll ship high-quality code (Java) in fast cycles while showing other engineers how AI transforms productivity, code quality, and development velocity. You'll leverage AI to accelerate every phase of the software development process--from design and implementation to testing and deployment.

What you'll do

==================

AI-Powered Software Development

Build Production-Ready Solutions

Design and implement scalable microservices with API-first mindset Develop RESTful, GraphQL APIs as needed with comprehensive documentation Build cloud-native applications using modern architecture patterns Deliver well-tested, production-grade code with CI/CD automation Ship features quickly using AI to accelerate development cycles

Leverage AI Throughout Development

Use AI for all coding tasks: feature implementation, refactoring, test creation, documentation, debugging Employ Claude Code, GitHub Copilot, and LLM APIs to write better code faster Apply AI-assisted code analysis, optimization, and security scanning Achieve measurable and significant productivity improvements through AI integration Demonstrate when to use AI vs when human judgment is critical

API-First & Microservices Excellence

Design clean, versioned APIs that prioritize developer experience Implement event-driven architectures and asynchronous communication patterns Build loosely coupled microservices with clear boundaries Apply domain-driven design principles and service decomposition strategies Create comprehensive API documentation and developer guides

AI Implementation & Automation

Build AI-Powered Development Infrastructure

Implement Model Context Platform (MCP) servers for improved AI-assisted development and be efficient in using the ones built effectively. Create AI-assisted CI/CD pipelines with automated code review, testing, and deployment Automate and apply various quality metrics to ensure we go faster without cutting corners. Develop reusable AI tooling and templates that other engineers can adopt Integrate AI into development workflows for maximum impact

Drive AI Adoption & Best Practices

Document patterns and share learnings about AI-first development Mentor team members on effective AI tool usage and prompt engineering Measure and communicate productivity gains from AI integration Establish best practices for AI-assisted code generation and review Demonstrate practical AI applications that solve real development challenges
