Breadcrumb

6d • Hybrid

About The Position

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.
