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.

• 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.
