About our technology

We use Kubernetes to orchestrate our containers, allowing us to offer cloud (AWS & Azure) and on-premise deployment options of our platform. Our infrastructure is maintained by a state-of-the-artgitops/IaC pipeline.

We heavily lean on open-source tools and libraries, as well as maintaining our own, to make development faster, simpler, and more consistent. Our code is managed using Git, undergoes peer review before we test, package and deploy through our CI/CD pipelines.

About the role

Joining our team as a Senior Java Developer you will collaborate with our cross-functional team to design, build, and optimise features/technology for the CSG Quote & Order product.

In your first 90 days, you’ll get comfortable with our system, build strong relationships with the team, and kick-off new feature development to deliver awesome outcomes for our customers.

What you will do

• Champion clean, efficient code by giving thoughtful PR feedback and holding the team to high standards.

• Mentor and inspire the team by sharing your expertise and helping others level up their skills.

• Collaborate with product and design teams to translate customer needs into impactful, user-friendly features.

• Take ownership across our systems. Spot inefficiencies, resolve bottlenecks and keep everything running like clockwork.

• Evaluate new tools, frameworks, and trends to keep us at the forefront of innovation and productivity.

Role requirements

• You’ve been building with modern Java SE (17+) for 5+ years and know your stuff.

• You thrive on teamwork, can communicate and collaborate easily with your teammates.

• Linux and Docker are your natural habitat. You’re completely at home in this environment.

• You know your way around the development tools like GitHub, Maven and Kubernetes

• Bonus points if you’ve dabbled in: AWS/Azure, PL/PGSQL, MyBatis, Camunda BPMN Engine, REST API frameworks and other parts of our technology stack.

Perks & benefits

• Work from anywhere: CSG has a global policy called "Flexibility First" that allows employees to work from wherever they feel most productive. The Quote & Order team does not maintain a dedicated office space, so your position will be 100% remote with the exception of several in-person workshops during the year (in Bali – see below – and Melbourne).

• Twice-yearly workshops in Bali: Twice a year the whole Quote & Order team gets together in Bali, Indonesia for dedicated in-person time including team presentations, hackathon sessions, training and team-building activities.

• Paid volunteer days: Everyone at CSG gets two paid days per year to volunteer at a community organisation of your choice.
