About Bark Bark is an online services marketplace connecting customers with professionals across over 1,000 categories. Operating in nine countries including the UK, US, Australia, Canada, and New Zealand, we're transforming how people find trusted service providers for everything from home improvement to professional services. Our platform uses cutting-edge technology to match customers with the right professionals quickly and efficiently.

With a integral team of over 220 people, we're currently undergoing an exciting transformation: migrating from a lead generation model to a full marketplace platform with subscription-based pricing. As a profitable, PE-backed scale-up (EMK Capital), Bark offers the best of both worlds: the agility and innovation of a fast-moving business combined with financial stability and resources for growth. We recently launched our new marketplace model in Australia (Q4 2025) and are preparing for rollout to the UK and US markets in 2026.

You'll have genuine ownership, responsibility, and the opportunity to shape our commercial strategy during a pivotal transformation phase with the chance to make your own contribution to our journey. We are looking for a Senior Backend Engineer to join our growing team. You'll become a core part of our small, highly agile team which is responsible for transforming our product.





A/B testing and test‐measure‐learn approaches are close to our heart and you will work equally across figuring out solutions to user problems and how we will scale our technical systems. You'll work across our tech stack to solve a variety of challenges from our back‐end processes, to our APIs and to our front‐end product.
