Senior Staff Engineer - Platform or Remote

🚀 We’re on a mission to make money work for everyone.

We’re waving goodbye to the complicated and confusing ways of traditional banking.

With our hot coral cards and get-paid-early feature, combined with financial education on social media and our award winning customer service, we have a long history of creating magical moments for our customers!

We’re not about selling products - we want to solve problems and change lives through Monzo ❤️

We have around 450 engineers out of roughly 5,000 people in total - and we have big ambitions. There are many interesting challenges ahead, and we're happy for people to move between teams or to specialise, whatever you prefer. As an engineer here you'd be able to work directly with anyone across the company, and we run regular knowledge-sharing sessions so you’ll learn heaps about everything from how banks work to effective communication.

This role sits in our Platform collective. Our Platform team includes over 75 technical staff (Platform Engineers, Backend Engineers, ML Engineers, Mobile Engineers, Web Engineers, Analytics Engineers, and Data Scientists).

Our mission is to help Monzo scale effectively, empowering our technology teams to build magical experiences for our customers all over the world. We do this by providing a highly available, reliable, secure, compliant, and performant platform of data, software, and infrastructure solutions that:

• meet the needs of our growing business
• accelerate the productivity of Monzo engineers, data scientists, and data users
• maintain cost-efficiency that is at most linear to the growth of our business

A Senior Staff Engineer at Monzo is a technical (IC) leadership position. You will have company-wide influence, working with other collectives to grow Monzo.

In this role you’ll be focused on improving our platform resilience. You’ll sit at the intersection of our platform and product engineering teams to make it easier for engineers to build resilient systems; improving our platform abstractions and tooling in the process.

More specifically, you’ll:

• Expect to be hands on and deeply technical with code and infrastructure, using your software engineering and system building skills and expertise to lean in and solve deep technical challenges
• Partner with the Engineering Director for Platform and other ICs to provide technical leadership around resiliency across Monzo
• Build a deep understanding of our platform and then work to strengthen the reliability surface that sits between teams - building and enhancing the tools, patterns and guardrails that make resilient choices the easy ones
• Promote and maintain a culture where every engineer feels supported to design, build and operate reliable systems that work on a global scale
• Understand several work-streams across your group, keeping enough context to regularly provide technical advice and challenge to other engineers
• Use your expert knowledge and experience to lead architectural discussions for the most complex systems in the collective. You’ll do this in order to arrive at solutions that are robust and optimal given the context
• Championing high standards by celebrating success and providing constructive feedback to help the team improve
• Foster a culture of quality within your collective. Proactively champion measures to test work, and make this easy
• Pro-actively mentor, sponsor and up-level engineers
