About Customer Operations at Monzo:

The Customer Operations team provides tech-led and human support experiences for now over 10 million customers. We don’t just solve customer problems - we aim to improve customer satisfaction and product engagement by providing effortless, fast, and empathetic support. Our Operations tech team has three focus areas:

Creating in-app experiences that enable customers to solve their own problems. As well as building customer experiences ourselves, we help all product teams at Monzo build better products by developing a system of reusable components that other teams can use.

Tooling that enables our ~3,500 customer support agents to give the best possible support for customers and automating away things that distract from that.

Workforce management systems that ensure our customers are connected to high-quality support as quickly as possible, efficiently route customer requests to the right support person at the right time and manage forecasting and scheduling of a ~3,500 strong workforce.

This role will primarily focus on our customer support tooling and workforce management systems.

As a Staff Engineer:

A Staff Engineer at Monzo is a technical (IC) leadership position. As a Staff Engineer in the Operations collective at Monzo, you will:

Partner with the Engineering Director supporting the collective and provide technical leadership across 3+ squads and ~20 engineers.
Work collaboratively with product, data and operational leaders to identify and execute on opportunities that further the organisation’s goals and strategy, bringing the right level of clarity, urgency and rigour as appropriate.
Work on solving multi-faceted optimisation problems at scale, such as how to maximise the leverage of technologies like LLMs to aid human workers or how to forecast, schedule and efficiently route requests through a workforce of thousands of people and more generally solve high quality customer support at scale.
Oscillate between contributing to high-level planning and strategy and organisational leadership and diving deep into the execution of problems and getting hands-on as necessary.
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.
Keep a high bar for technical excellence in the collective, through your own work, highlighting the work of others and calling out when things haven’t quite met the bar.
Pro-actively mentor, sponsor and up-level engineers.
