Senior staff backend engineer

🚀 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 600 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.


Senior Staff Engineer (IC)

A Senior Staff Engineer at Monzo is a hands on engineering leadership (IC) position. As a Senior Staff Engineer you’ll:

* Partner with Engineering Directors to shape the technical and product direction of a collective, providing leadership across multiple squads (30–70+ engineers) and ensuring alignment with company‑wide priorities.
* Be hands on in both coding and architecture, leading from the front.
* Partner closely with Product and Design leadership to define strategy, shape roadmaps, and make high‑quality trade‑offs that maximise business and customer impact across the collective.
* Mobilise teams across your collective around high‑impact problems, creating clarity, alignment and momentum, injecting urgency when needed, or slowing things down to ensure safety and long‑term sustainability.
* Lead and influence architectural direction for the most complex systems, ensuring cohesive, scalable designs across multiple teams and aligning local decisions with the broader system strategy.
* Set and uphold a high bar for technical excellence across the collective, driving improvements in quality, reliability and scalability, and fostering a culture where engineers hold each other to that standard.
* Proactively mentor, sponsor and develop senior engineers and future leaders, multiplying your impact by enabling others to operate at a higher level.


What you’ll be using / What you’ll be working on

We rely heavily on the following tools and technologies:

* Go to write our application code (there’s an excellent interactive Go tutorial here)

* You have a track record of leading complex, high‑impact systems and driving technical direction across multiple teams
* You combine strong technical judgment with product and business awareness, making pragmatic trade‑offs
* You’ve worked on scalable backend, distributed or data‑intensive systems
* You’re comfortable operating in ambiguous problem spaces, helping teams define direction and execute
