IOS Engineer

Overview

Monzo has around 400 engineers and 4,500 people in total. We build a native Swift iOS app for more than 12 million users and work in small, interdisciplinary squads that move fast, iterate on user experience and value data‑informed decisions. We value learning, curiosity and impact over graduation letters or seniority.

As an iOS engineer you will work in an autonomous product squad alongside Android engineers, backend engineers, user researchers, product designers, product managers, QA testers and data scientists. You will be responsible for a company‑wide goal rather than a single feature. Your impact spans the personal banking product, customer support tools and the mobile platform squad that enables other engineers to move faster.

You will build polished user experiences, ship products on the App Store, make architecture decisions, write unit, UI, snapshot and integration tests, and mentor teammates.

• Product mindset: you care about customer outcomes and make data‑informed decisions.
• Swift expertise: you have experience programming in Swift and shipping an app to the App Store.
• Impact focus: you care about the impact your work has on customers rather than the number of lines of code you output.
• Design translation: you love turning excellent design into beautiful products.
• Ambiguity tolerance: you are comfortable working in a team that deals with ambiguity.
• Computer science fundamentals: you understand core computer science principles.

Our interview process involves three main stages: the initial call, a take‑home task or pair‑coding exercise, and the final interview that includes a system‑design and a behavioural interview. The average process takes around 2‑3 weeks.

£78,000 – £110,000 base salary, stock options and benefits. We provide all engineers with a Mac Book Pro, a flexible working schedule, learning budgets, relocation support, visa sponsorship for the UK (remote outside UK not supported) and flexible working hours. We celebrate diversity and welcome all applicants.

Monzo is an equal opportunity employer and we celebrate diversity. We do not discriminate on race, color, religion, national origin, sex, gender identity, or any other protected class.
