Why Join Archa

For too long, Finance teams have been stuck managing corporate spend using legacy tools designed for a different era. We saw growing companies relying on shared credit cards, chasing paper receipts, and manually reconciling expenses in spreadsheets. It was a friction-filled process that wasted time and leaked money.

We built Archa to solve this. We are not a bank; we are a technology company building the smartest corporate card and spend management platform in the market.

The Role

We’re looking for a Senior Full-Stack Engineer to help design, build, and scale our platform across both frontend and backend systems. This role suits someone who enjoys ownership, works well across disciplines, and values clear communication and strong team behaviours.

You’ll work closely with product, commercial, and engineering teams to turn complex requirements into practical, well-designed solutions that deliver real business impact.

Engineering at Archa

Our engineering team is deeply involved in product planning, architecture, and delivery. Engineers are encouraged to challenge ideas constructively, communicate clearly, and take responsibility for the systems they build.
