Lead Backend / Full Stack Developer (Java, AWS, Terraform)

Sydney / Hybrid | Permanent

Our client is an Australian product team building a SaaS platform designed to transform complex, field-based industries. Their focus is on helping businesses streamline processes through digital automation - boosting productivity and profitability while keeping the user experience simple, intuitive, and stress-free.

They're seeking a Lead Backend / Full Stack Developer to take ownership of the backend and infrastructure as the platform scales. This is a hands-on leadership role where you'll guide architecture, mentor, and play a critical role in shaping how the product evolves.

The Role

  • Lead backend development (Java-first, with a functional programming approach)
  • Drive infrastructure and DevOps practices (AWS, Terraform, IaC, pipelines, load balancers)
  • Partner with a Principal Software Engineer to design and deliver new features
  • Collaborate with Product and UX to bring scalable, practical solutions to life
  • Build and maintain integrations across financial platforms (Xero, Stripe, Square) and operational tech (IoT systems, devices, and equipment)
  • Implement strong security measures (Spring Security, oAuth2)
  • Optimise database performance (SQL/PostgreSQL, CRUD)
  • Contribute to knowledge-sharing and technical documentation


Skills & Experience

  • 3-5+ years of backend development with solid Java (21/24) experience
  • Strong grounding in functional programming
  • Hands-on experience with AWS cloud architecture and Terraform/IaC
  • Familiarity with Spring Security and security best practices
  • Strong SQL/PostgreSQL skills with a focus on optimisation
  • Exposure to Lambda functions and oAuth2
  • Background in complex third-party integrations (finance or IoT platforms)


Worth Noting
This is an opportunity to:

  • Take ownership of architecture and infrastructure on a growing platform
  • Combine leadership with hands-on coding and problem-solving
  • Work on real-world engineering challenges at the intersection of finance, IoT, and cloud
  • Join a collaborative Aussie team that values autonomy, curiosity, and doing things smarter


If you're looking for a role where you can shape a product end-to-end while still staying close to the code, this one is worth exploring.
