Who is Shift?

At Shift, we’re business specialists dedicated to helping Australian SMEs take control of their cashflow, streamline trade terms and choose the right financial products. We believe Australian businesses are the driving force behind our economy and are core to our communities. That’s why our business expertise, focus on relationships, and market-leading technology is at the core of everything we do. We’ve helped solve the credit and payment pain points for more than 30,000 businesses, providing over $6 billion in aggregate funding. Our unique approach to product innovation combined with our collaborative culture means you can build your career in a supportive environment. You’ll be joining a diverse team of over 300 people who are always looking to deliver better outcomes for Australian businesses.

About the role

We're looking for a Full Stack Software Engineer to join our team. This role can be tailored to either a balanced 50/50 full stack position or one with a stronger focus on front‑end development – depending on your strengths and interests. You'll collaborate to deliver high‑impact features, engaging user experiences, and robust backend systems that power our platform. You'll contribute to technical decisions and hands‑on implementation within a tight‑knit, agile team focused on delivering value to our users.

What you’ll do

• Design, develop, and maintain modern, scalable web applications using JavaScript/TypeScript (ReactJS) and C# (.NET)
• Support and enhance backend services to ensure seamless integration and robust system functionality
• Work with designers, product owners, and the team to take concepts from idea to delivery, with a focus on usability and performance
• Participate in planning, prioritisation, and execution within agile sprint cycles
• Contribute to architectural discussions for both front‑end and back‑end, helping to ensure maintainability and scalability
• Follow engineering best practices, code quality standards, accessibility, and promote continuous improvement
• Stay current with emerging technologies and share insights with the team
• Help ensure system reliability and meet objectives through high‑quality, maintainable code

What you’ll bring

• 3+ years of experience building production software in full stack or front‑end‑focused roles using modern frameworks
• Proficiency in JavaScript/TypeScript, with experience in React.js (or similar), as well as C# and .NET
• Experience integrating applications with RESTful APIs and event‑driven microservices
• Experience working with Azure or other cloud platforms is a plus
• Familiarity with DevOps tools and practices (e.g. GitHub Actions, TeamCity, Octopus)
• Passion for crafting intuitive, responsive, and accessible software
• Commitment to testing, quality, and reliable delivery across the software stack
• Strong collaboration and communication skills – you enjoy working cross‑functionally
• Curiosity and enthusiasm for learning and problem solving in a dynamic environment

Key benefits

• Collaborative teams – a flat structure means everyone can learn from colleagues and senior leaders around the business.
• Be involved – come together with all of your colleagues every 100 days to share the product and technology roadmap and business strategy.
• Flexible working environment – we’re headquartered in North Sydney with state‑based workplaces and offer a flexible work policy.
• Family support – industry‑leading 26 weeks paid parental leave.
• Purpose built spaces within our office – designed for collaboration, brainstorming, socialising, and focused work.
• Range of benefits supporting your physical, psychological and financial wellbeing. From a day off on your birthday to excellent end‑of‑trip facilities.
