Senior C# Full-Stack Software Engineer

Breadcrumb is a construction tool built for the people who actually build things. We replace paper-based processes with a digital tool that makes worksites safer, more connected and more compliant - in real time, in workers' hands.

From a 15-person start-up four years ago to a global team of 80+ with offices in Melbourne, London and San Francisco, we now serve over 1,000 construction companies and 1.5 million workers across ANZ, the UK, Ireland and North America. We're moving fast and we're looking for engineers who thrive in that environment.

Trust and experimentation are key to the engineering culture at Breadcrumb. Low gatekeeping, individual ownership, and plenty of room to try new things.

What You'll Be Doing

As a Senior Software Engineer, you'll own features end-to-end from prototype to production - and help shape the architecture of a tool used by hundreds of thousands of workers every day. You'll work closely with product, design and fellow engineers in a small, high-trust team where your decisions genuinely matter.

• Deliver new features while improving the quality and architecture of existing technology
• Collaborate with product and design to scope and ship meaningful work not just tickets
• Identify opportunities to improve operational excellence, ways of working and customer outcomes
• Break large pieces of work into small, shippable units prioritising learning over perfection
• Coach and support engineers of all levels; be someone teammates want to learn from
• Think holistically about the impact of your decisions on the whole business, not just the dev team

Our stack

Core: Azure, C# .NET, Microsoft SQL Server, GraphQL, TypeScript, React, Flutter (iOS, Android, mobile web)

We evolve our stack continuously. Bonus if you've used SST, Pulumi or Terraform - a willingness to get hands-on with unfamiliar tech matters more than ticking every box.

What You'll Bring

• Strong experience in C# .NET full-stack web development
• Proven ability to carry a feature from start to finish — spec, build, test, ship
• Solid React and TypeScript experience, comfortable connecting frontends to backends
• Experience reading and writing SQL and comfort with unit and UI testing
• A collaborative style - you work well with devs at all levels and bring others along
• Clear communication across technical and non-technical stakeholders
• A genuine curiosity and eagerness to learn, improve and try new things

Nice To Have But Not Deal Breakers

• GraphQL
• Infrastructure as code
• Claude Code
• Using & configuring NX
• Flutter
• Azure

• Flexible working: Hybrid setup with autonomy to work where you work best, and come in when it counts
• Health & wellbeing: EAP, additional mental health leave and Minimum Viable Days
• Family-friendly: Comprehensive parental leave for all caregivers
• Impact at scale: Your work ships to over a million construction workers globally, helping them get home safe every day
• High growth environment: Real ownership, real impact, and room to shape not just the product but how a whole new domain is built
