Job Description:

We seek a Principal Engineer to be the technical leader for the Everyday Rewards tribe, directing engineering across multiple squads while staying involved in day-to-day delivery. This is not purely strategic. You will directly engage with squads on difficult issues: guiding integration design, reviewing solutions, unblocking challenges, and advising on complex distributed systems tradeoffs. You will also identify cross-squad patterns, enforce standards, and drive consistency to enable fast, cost-effective tribe movement. The role requires both architectural vision for future direction and deep engineering credibility for practical details.

Job Responsibility:

  • Own and evolve the architectural runway for the Everyday Rewards tribe, defining target-state architecture and managing pragmatic delivery steps
  • Serve as the primary technical reference point, providing hands-on guidance on solution design, implementation tradeoffs, and engineering practices across squads
  • Drive tactical solutioning for complex problems, including partner integrations, loyalty processing, real-time event pipelines, and customer-facing digital experiences
  • Identify and address cross-squad technical concerns (consistency, shared components, standards, technical debt) with a delivery-aware lens
  • Establish and continuously improve engineering standards (testing, observability, CI/CD, secure-by-design) and produce fit-for-purpose solution architectures

Requirements:

  • A minimum 10 + years experiences a engineer with most recent as a Principal Engineer, Senior Technical Architect, or Senior Tech Lead — ideally with an eCommerce, loyalty, or high-volume consumer platform background
  • Strong technical skills in .NET (C#, ASP.NET MVC, WebAPI, Entity Framework), Graph QL and Node.js
  • Extensive cloud platform experience (GCP/Azure) and familiarity with containerisation (Kubernetes/Docker Swarm)
  • Expertise in DevSecOps, CI/CD, infrastructure as code, and delivery automation
  • Experience with web security (OWASP Top 10), microservice architectures, NoSQL databases, and event messaging/queues (Kafka, RabbitMQ, Azure Event Hubs)
  • Proven ability to influence multiple teams, raise engineering standards, and facilitate team growth
What we offer:
  • Team discounts across our range of Woolworths Group brands you know and love and a robust rewards program that celebrates and incentivises purpose-driven work
  • A global business with endless career possibilities around every corner and across every discipline – with valuable exposure to a vast and exciting business network
  • A progressive and flexible 'work from anywhere' policy that gives you the opportunity to harmonise work, life and your wellbeing
  • A range of programs to help you prioritise and manage your wellbeing, including 24/7 access to the Sonder app
