Our Operations Machine Learning team ⭐
We’re building the machine learning and optimisation systems that help Monzo provide fast, efficient and resilient customer
support at scale.
You’ll lead Machine Learning for our Workforce Management vertical: the organisation that makes sure Monzo has the right human
support supply to meet customer demand. The team works on demand forecasting, real-time supply <> demand matching, problem routing
and escalation, and predictive models that help us understand how long work will take, what might become late, and where the next
best human support should be assigned.
This is a great role for someone who is still close to technical work. You might be a Tech Lead, Team Lead, Senior Machine
Learning Scientist or Senior Machine Learning Engineer who has recently been building models and systems yourself, and is excited
to grow into a broader leadership role.
Not everything here is about LLMs. You’ll work on rigorous ML, forecasting, optimisation and operations research problems where
quantitative thinking, pragmatic delivery and strong product judgement really matter.
You’ll lead a growing team of Machine Learning Scientists, embedded in product squads working alongside data scientists, backend,
mobile and web engineers, product managers, user researchers, designers and operations specialists.
🔑You’ll play a key role by…
impact for customers and human agents.
time-to-completion prediction.

every single requirement. At Monzo, we’re dedicated to creating a diverse and welcoming team. If you’re passionate about this role
and keen to learn and grow with us, we encourage you to apply— even if you don’t have everything that's listed just yet. Drop us
