Senior Backend Engineer

• Join around 650 engineers building Monzo's in-house banking platform. • Work in a squad alongside product managers, marketers, user researchers, designers, mobile and web engineers, data analysts, business analysts, and writers. • Build and support a particular part of Monzo within one of its collectives: Core Banking, Business Banking, Wealth, Borrowing, Growth, Payments, Platform, Fincrime, Security & Expansion. • Get exposure to machine learning and AI work, which sits at the forefront of many collectives from fighting financial crime to building smarter financial tools. • Go through one standard interview process, with the best team match found at the end based on your skills, experience, and preferences. • Join at L50 on Monzo's Engineering Progression Framework. • Work from London, Cardiff, or fully remote within the UK, with no mandated office attendance.

• Bring strong experience working on the backend of a technology product. • Want to build a product you and the people you know use every day. • Bring a product mindset, caring about customer outcomes and making data-informed decisions. • Work comfortably in a team that deals with ambiguity. • Take an interest in distributed systems and writing resilient software. • Bring some experience with strongly-typed languages such as Go, Java, C, or Scala. • Enjoy learning new things, since Monzo hires technically agnostic and asks for no formal qualifications or degree.

• Have worked with any of Monzo's stack, including Go, Cassandra, Kafka, Kubernetes, Docker, Envoy Proxy, AWS, GCP, or React, though no prior knowledge is expected. • Have built systems in a regulated or financial services environment. • Have contributed to open source software, which Monzo does as much as possible. • Apply even if you do not tick every box, which Monzo explicitly encourages. • Use a preferred name to apply, as Monzo does not need full or birth names at application stage.

• Collaborate with your squad to make a difference to customers. • Write application code in Go, supported by organised onboarding to get up to speed. • Work with Cassandra for persistent data storage and Kafka for asynchronous message queues. • Schedule and run services using Kubernetes and Docker, with Envoy Proxy handling RPC. • Build on AWS for production infrastructure and GCP for data infrastructure. • Work with React on public web apps and internal tools. • Support systems that connect to third parties through physical datacenters.

• Earn £105,000 to £135,000 plus incentive awards tied to your performance. • Work part-time if you prefer, which Monzo will accommodate wherever it can, whether to meet other commitments or strike a better work-life balance. • Manage your schedule around children drop-offs and pick-ups, walking the dog, avoiding peak commuting, gym slots, appointments, or supporting family in an emergency. • Work with no mandated office attendance, even if you live nearby, with Monzo covering costs if you live outside London and are asked to come in. • Get help relocating to the UK and visa sponsorship. • Keep meetings within core hours, so work and life stay balanced. • Spend a £1,000 annual learning budget on books, training courses, and conferences. • Apply any time, since there is no closing date on this role.

Monzo is on a mission to make money work for everyone, moving away from the complicated and confusing ways of traditional banking.

Around 650 engineers design and build its in-house banking platform, working across products, infrastructure, security, payments, finance, customer operations, financial crime, and data, and contributing to open source software wherever possible.
