Senior Backend Engineer

Ever imagined saying, "I helped launch the future of transportation"?

We're rewriting the rules of urban mobility. At Vay, customers tap a button and a car arrives - with no one inside - powered by our world-first Remote Driving technology on real public streets.

We're live in Las Vegas and scaling fast, powered by a strategic investment of up to $410 million from Grab. Our mission is simple: replace private car ownership with a faster, cleaner, door-to-door mobility model. If you want to build something real, visible, and genuinely transformative, you'll feel right at home here.

• First to roll out vehicles in both Europe and the USA on public roads without a human being inside & currently the 2nd largest commercial, driverless car fleet in the Western World.
• We've partnered with Kodiak to bring remote-driving technology to autonomous trucks in the US, showcasing our ability to integrate our system into heavy-duty commercial vehicles and expand the applications of our tech across the US.
• We've completed over 150,000 trips so far and are busy multiplying our Las Vegas fleet just to meet demand!
• ...And soon we'll be expanding across the US & Europe

At Vay, backend engineering goes far beyond building APIs. We're developing the systems that coordinate vehicles, remote drivers and customers in real time, powering everything from intelligent dispatch and fleet operations to the customer experience.

You’ll tackle complex distributed systems challenges where reliability, scalability and real-world impact aren’t just engineering principles, they’re fundamental to making our service work.

As a Senior Backend Engineer, you’ll have the opportunity to shape the architecture behind a growing mobility platform, take ownership of meaningful technical challenges and see the direct impact of your work on a service operating in the real world.

If you thrive on solving complex problems and want to push the boundaries of what's possible in mobility, we'd love to have you on board.

• Design & Develop: Build and maintain scalable backend systems that support Vay's growing fleet, customer experience and operational infrastructure, using Go and modern cloud‑native technologies.
• Own End-to-End Solutions: Take ownership of technical solutions from understanding the underlying problem and defining the approach through to implementation, deployment and continuous improvement.
• Shape Technical Architecture: Influence architectural decisions, evaluate technical trade-offs and help establish engineering practices that enable our platform to scale reliably.
• Solve Complex Engineering Challenges: Work at the intersection of software, physical vehicles and operational systems, building reliable solutions to problems that go beyond conventional backend development.
