Lead Platform Engineer

We are building the financial system for the next century. One where control sits in the hands of customers — not banks. Where money moves on rails that are faster, smarter, and radically more efficient. Where wealth management tools help you grow your savings for decades — and build generational wealth. Where fewer intermediaries mean more value stays where it belongs: in our customers’ pockets.

We operate with long-term ambition and absolute conviction. We are not here to iterate on the past — we are here to redesign it. This is a defining moment to join us.

We are building what we believe will become one of the most important financial institutions in the world. That requires exceptional talent, relentless standards, and people who care deeply about the work. At ARQ, we are turning the financial system upside down — starting in the Americas. We are nimble, but ambitious. We move fast, learn fast, and innovate relentlessly. Technology is our greatest ally, and execution is our edge. We build as a team. We think long term. We aim for world-class in everything we do. If you are exceptional at what you do — and ready to help redefine finance — we’d love to meet you. Are you ready to build what comes next?

About the team

We believe that small teams with the best talent outcompete massive companies with mediocre capabilities. That's why we have gathered a set of people who have done it before at iconic companies like Revolut, Uber, Amazon, Block and UBS: we owned some of the most loved and profitable products, delivered top-notch transaction processing platforms, created beautiful mobile applications - and helped them become profitable companies that changed the lives of millions of people.

In our quest to reshape the global financial system we have raised tens of millions of dollars from leading investors like Sequoia Capital, Founders Fund, Brevan Howard Digital, Y Combinator and Kaszek Ventures.

We’re looking for a world-class, hands-on Senior or Lead Platform Engineer who takes a software engineer’s approach to architecting and building engineering infrastructure.

Our engineering culture is focused on fully type-safe, declarative & testable infrastructure as code and we’re looking for like-minded engineers who also value these properties to join us.

The ideal candidate will have a raw passion for programming (any language), a broad knowledge base and the ability to dig deeply into any technical area required to enable our product engineering team to deliver the best product on the market for managing modern finances.

We architect extreme-quality, automated systems to orchestrate hundreds of backend services & databases across tens of kubernetes clusters, tens of thousands of data processing jobs and tens of thousands of CI/CD builds per week - if that excites you, we want to talk to you.

• Problem-solve, analyse and debug infrastructure issues & opportunities with members of the wider engineering team.

• Strategise & execute on the rollout techniques for making sweeping infrastructure changes as we constantly integrate new best practices & security improvements into our setup.

• Orchestrate multi-region infrastructure and deployments to meet security, availability and compliance requirements.
