About our Engineering Teams:
We have around 650 engineers across Monzo who design and build our in-house banking platform. We have big ambitions for the future, and technology plays a big role in creating a bank our customers want, so engineers at Monzo collaborate across disciplines to solve interesting challenges throughout the company.
These range from the products our customers use everyday to underlying infrastructure, security, payments and finance, customer operations, financial crime, and data, to name just a few areas. As a bank, there is scope for impact across a huge number of opportunities.
How we work đť
Our main tech hub is in London, but our engineers live everywhere in the UKâ from Brighton to the Western Isles. We value meeting in person but we don't have a mandated requirement on office attendance, even if you're nearby. We believe you'll do your best work if you are where you want to be. If you live outside of London and we ask you to come into the office, Monzo will support you with the costs â¨
Our offices are naturally social, especially Tuesdays, Wednesdays and Thursdays, which happen to line up with our twice-weekly Monzo lunches & treat Thursdays đ˝ď¸
Teams also schedule time together often for work and play â in or around the office, or online.
Set up a work schedule that delivers impact and fits your life:
At Monzo, we value connections, flexibility, and wellbeing. We keep our meetings during core hours to stay connected and believe in maintaining work/life balance.
Youâll be empowered to manage your work in a way that suits you and your team, giving you the freedom for children drop-offs and pick-ups, walking your dog or adventurous cat, avoiding peak commuting times or gym slots, appointments, or supporting your family in an emergency đŁâ¨
Reasons to use Rodeo
Iâm in my final year doing Economics and I donât know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer â it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) donât need a masters. Letâs look at the ones youâd be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet â that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
