Buddy Advisory is proud to be partnering with Business Automation Works (BAW), a fast-growing business delivering smart automation solutions to the financial services sector, including accounting practices. By replacing manual, time-consuming processes with smarter, more innovative ways of working, BAW lifts productivity and job satisfaction, freeing practice managers, partners, and admin staff to focus on what matters most: client relationships and engagement.

The role

A newly created Senior Software Engineer vacancy now exists for an experienced engineer to join the growing team in Geelong. This is a hands-on role spanning BAW's product suite with a focus on backend architecture, API and service development, data workflows, solution design, and technical mentoring. You'll bring real, lived experience taking software through to production, a high-agency mindset, and the appetite to help shape not just what we build, but how we build it.

The responsibilities

• Design, build and maintain .NET backend services powering BAW's product suite, from architecture through to performance tuning.
• Develop and maintain backend APIs, authentication and logging patterns, and contribute to shared, reusable application components.
• Build and maintain data ingestion, transformation and processing workflows, ensuring reliable, high-quality data movement across systems.
• Owns and drives the adoption of AI-assisted tooling across the team's processes and ways of working.
• Contribute to database schemas, design SQL queries and stored procedures, seeking to continuously improve performance, data quality and observability.
• Contribute to solution design, technical specifications and acceptance criteria for backend work.
• Lead or contribute to incident investigation and resolution for backend services and data processing systems.
• Mentor developers, review code, and help lift engineering standards and practices as the team matures.
• Partner closely with product, engineering leadership and the Customer Success team to translate business needs into technical solutions.

The requirements

• Extensive software engineering experience in a SaaS/scale-up environment, with a track record of taking software through to production, end-to-end.
• Strong, current .NET/C# and SQL Server experience, mandatory. React is highly regarded.
• Broad backend capability across APIs, background processing and data workflows — not just customer-facing app work.
• A high-agency, ownership mindset; you think commercially and about customer impact, not just technology for its own sake.
• Genuine curiosity and energy for AI-assisted tooling, ideally backed by professional and personal builds.
• Comfort with breadth, ambiguity and switching context across many systems, without needing a manual to get things done.
• Excellent people skills and the ability to coach, mentor and grow others, complementing your engineering depth.

Why join

• Broad exposure across a modern, containerised, microservices-based stack.
• Genuine influence over technology stack, engineering standards, solution design and team development.
• A clear pathway to a future Technical Lead role as the team and business scale.
• Based in our Geelong office, with real proximity to customers and commercial impact.
• A leadership team actively investing in AI-assisted tooling and modern ways of working.
• A fast-growing company solving genuinely meaningful problems for financial services businesses.
