Job Description:

We are seeking a Senior Software Engineer to drive the technical direction and shape the foundations of our modern, revenue-generating platforms at Cartology. This role demands a high degree of technical ownership, focusing on raising engineering standards and influencing our client-facing ecosystem's architecture. The ideal candidate is a pragmatic problem-solver, adept at balancing rapid delivery with long-term system health in a commercial setting. While highly collaborative, you must possess the leadership mindset to work independently, navigate ambiguity, and take full accountability for the platform's success. This position is perfect for a platform-level thinker eager to move across the stack to solve complex challenges.

Job Responsibility:

Lead the instrumentation of the platform to drive data-informed decisions and proactively maintain system health using modern monitoring tools
Contribute to high-level planning, technical documentation, and the selection of long-term technology choices
Drive the design and evolution of a scalable, resilient platform architecture, taking end-to-end accountability for major components
Raise the bar for engineering standards and code quality through rigorous peer reviews and mentoring
Balance technical debt with speed-to-market, making trade-offs to support a high-growth, revenue-generating environment
Design and optimise generic, scalable integration patterns across the ecosystem (CRM, AdTech, CMS)
Partner with Product, Design, and Marketing to translate business vision into robust technical reality and contribute to high-level planning and technology choices

Requirements:

Minimum of 5 years commercial experience with a proven track record of developing and scaling large-scale, mission-critical web applications
Deep technical proficiency in server-side technologies (Kotlin/Java, Spring Boot), software design patterns, and designing complex, high-availability, service-based architectures and RESTful environments
Proven experience with client-facing, revenue-generating systems, effectively balancing quality and commercial urgency
Exceptional communication and documentation skills for conveying complex technical strategies to all stakeholders
Strong experience with relational databases (PostgreSQL), cloud platforms (preferably GCP), containerisation, and a deep commitment to TDD/BDD and automated testing
Expert understanding of and ability to lead agile practices (Scrum, Kanban, XP), technical planning, and estimation, while working independently in an ambiguous, fast-paced environment

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
