Job Description
Cardiff, London or Remote (UK)
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 ️
Our Operations Data team consists of over 35 people across 4 data specialisms: Analytics Engineers, Data Analysts, Machine Learning Scientists and Data Scientists.
In our Operations Collective you'll have the opportunity to embed into an area that is the heart of how we work with our customers’ problems - and is full of data challenges. Machine Learning supports all aspects of Operations, from workforce planning, to customer support experience, to enabling teams to work effectively and efficiently.
As a Senior Lead ML Scientist, you’ll be on of the most senior Individual Contributors (IC) in the organisation, giving you a real opportunity to lead us into an exciting new phase of optimising Customer Operations, enabling us to craft a world-class support experience for over 9 million customers across the UK, and beyond as we continue to grow.
You’ll provide key technical leadership and ship highly impactful ML-based solutions. You’ll be empowered to work across the collective identifying the most impactful areas and pushing solution development forward while mentoring and levelling up less experienced ML practitioners. You’ll also impact how people across Monzo use ML tools to improve customer outcomes, including LLMs, which have their heaviest use within the Operations team.
Machine Learning Scientists at Monzo work end to end, so you’ll have the opportunity to collaborate across not only the data disciple, but with cross-functional squads, to deliver real-time models all the way to actual value
We’d love to hear from you if… What we’re doing here at Monzo excites you!
- You have a multiple year track record of excellence leading the technical work of a team in the development and deployment of advanced Machine Learning models tackling real business problems, preferably in a fast moving tech company
- You're impact driven and excited to own the end to end journey that starts with a business problem and ends with your solution having a measurable impact in production
- You have a self-starter mindset; you proactively identify issues and opportunities and tackle them without being told to do so
- You have a solid grounding in SQL and Python, are comfortable using them every day, and keen to learn Go lang which is used in many of our microservices
- You have experience developing and shipping deep learning, graph-based, and/or sequence-based ML architectures to production and delivering business impact
- You are comfortable exploring potentially ambiguous business problems within a complex and rapidly growing organisation
- You're excited about the potential of machine learning and can communicate those ideas to colleagues who are not familiar with the domain
- You’re adaptable, curious and enjoy learning new technologies and ideas
- You have experience in, and a passion for, mentoring other ML practitioners, sharing knowledge and raising the technical bar across the team
- You’re comfortable moving across teams within a larger organisation, optimising for where you can be most impactful and tracking multiple projects at once
- Experience working within large Customer Support and internal product spaces
- Experience with NLP tasks
- You have commercial experience writing critical production code and working with microservices
What’s in it for you
️ We’ll help you relocate to the UK.
We can sponsor your visa.
This role can be based in our London office, but we're open to distributed working within the UK (with ad hoc meetings in London)
We offer flexible working hours and trust you to work enough hours to do your job well, and at times that suit you and your team.
£1,000 learning budget each year to use on books, training courses and conferences.
We will set you up to work from home; all employees are given Macbooks and for fully remote workers we will provide extra support for your work-from-home setup.
Our interview process involves 3 main stages.
We promise not to ask you any brain teasers or trick questions!
- 30 minute recruiter call
- 45 minute call with hiring manager
- 1 take home task
- 3 x 1-hour video calls with various team members
Our average process takes around 3-4 weeks but we will always work around your availability.
You will have the chance to speak to our recruitment team at various points during your process but if you do have any specific questions ahead of this please contact us on
We’ll only close this role once we have enough applications for the next stage. Please submit your application as soon as possible to make sure you don’t miss out.
