Expertech is currently looking for a senior Founding .Net Engineer to join an exciting Governance technology start-up building next-generation enterprise software that simply couldn't have been built a year ago. This is a genuine greenfield opportunity to become a founding engineer, taking ownership of end-to-end development and helping shape both the technology and the product from the ground up. The business is leveraging modern AI capabilities to rethink how enterprise software is designed and delivered. You'll have significant autonomy, minimal red tape and the opportunity to build substantial functionality rather than simply working through a backlog of predefined tasks. Working remotely, you'll be involved in creating workflows, designing and building features end-to-end, developing integrations with external APIs and turning sometimes-vague requirements into sophisticated, working software. This isn't a role for someone who needs everything mapped out for them. It's for an experienced engineer who enjoys ambiguity, takes ownership and is genuinely excited by the prospect of building something significant.

Essential skills and experience

- Extensive commercial experience with .NET and C# development.
- Strong understanding of .NET architecture, software design principles and building scalable enterprise applications.
- Strong experience with React and TypeScript.
- Experience building and integrating REST APIs and working with external systems.
- Experience with AWS and cloud-based application development.
- Ability to take high-level or ambiguous requirements and translate them into well-designed, working solutions.
- Strong full-stack development capability,



with the ability to own features end-to-end.
- Experience leveraging AI tools to accelerate development, improve productivity and deliver complex functionality.
- A high degree of autonomy, initiative and accountability.

Desirable skills and experience

- Previous experience in a start-up or greenfield product development environment.
- Experience building enterprise SaaS platforms.
- Exposure to Governance, Risk or Compliance (GRC) technology.
- Experience establishing engineering standards, architecture and development practices.

Why apply

- Founding engineer opportunity: Play a pivotal role in building a technology business from the ground up.
- Genuine autonomy: No unnecessary red tape or layers of management. You'll have the freedom to make decisions and deliver.
- Greenfield development: Build current products, workflows and features without being constrained by legacy systems.
- AI at the forefront: Work with technology and AI capabilities that are fundamentally changing what's possible in enterprise software.
- End-to-end ownership: Take ideas from initial concept through architecture, development and delivery.
- Remote working: Work from wherever you do your best work.

This is a role for someone genuinely hungry to build something big. Expectations will be high, but so will the opportunity to make a meaningful impact. We are looking for candidates with eligible working rights for Australia, but this role can be WFH on the East Coast. This is an urgent position; however, suitable candidates with four weeks' notice can still apply. Please apply immediately by uploading your resume through the link.
