Job description
Job Overview We’re on a mission to make money work for everyone. We’re moving away from traditional banking approaches and creating new experiences with our hot coral cards, get‑paid‑early feature, and financial education on social media. This role is based in London or the UK and can be worked remotely. A Principal Engineer at Monzo is a hands‑on engineering leadership (IC) position. As a Principal Engineer you’ll shape the technical and product direction of Monzo, partner with Engineering and Product leaders to drive alignment across the company, remain hands‑on with coding and architecture, set direction for engineering effort, mobilise teams, lead architectural decisions, set a high bar for technical excellence, and mentor senior engineers and future leaders. Responsibilities * Partner with and guide Engineering and Product Leaders to shape the technical and product direction of Monzo, providing company‑shaping leadership across collectives (100+ engineers) and driving alignment with company‑wide priorities, owning problems that materially impact Monzo’s trajectory over the next 1‑5 years. * Remain hands‑on in both coding and architecture where it adds the most leverage, especially in complex, high‑risk or novel areas. * Actively identify high‑leverage opportunities for Monzo and set the direction of engineering effort towards the most impactful outcomes. * Mobilise teams across Monzo around high‑impact problems, creating clarity, alignment and momentum, injecting urgency, or slowing things down to ensure safety and long‑term sustainability. * Lead and influence architectural direction for the most complex systems, driving consistency and reuse across domains, aligning local decisions with the broader system strategy. * Set and uphold a high bar for technical excellence across Monzo, identifying and driving improvements in quality, reliability and scalability, and fostering a culture where engineers hold each other to that standard. * Proactively mentor, sponsor and develop senior engineers and future leaders, multiplying your impact by enabling others to operate at a higher level. Tools and Technologies * Go for writing application code (see interactive Go tutorial here). * AWS for most production infrastructure and GCP for most data infrastructure. * Feast for storing features and training/deploying models. Qualifications * Track record of leading complex, high‑impact systems and driving technical direction across multiple teams, domains or business areas. * Ability to think in multi‑year horizons to look around corners and build for the future, identifying opportunities before they present themselves. * Strong technical judgment combined with product and business awareness, making pragmatic trade‑offs. * Experience with large‑scale backend, distributed or data‑intensive systems. * Comfortable operating in ambiguous problem spaces, helping teams define direction and execute. * Influence and align senior stakeholders across engineering, product and beyond. * Care about outcomes and impact, using data to guide decisions and to iterate. * Enjoy mentoring and raising the bar for other engineers. Benefits * Unique role with discussions on base salary, incentive awards tied to performance, share options and benefits. * Relocation support to the UK. * Visa sponsorship. * Flexible working hours and trust to work the hours needed for your job. * £1,000 annual learning budget for books, training courses and conferences. * Work‑from‑home set‑up, Macbook provided for all employees; extra support for fully remote workers. Equal Opportunity Diversity and inclusion are a priority for us and we’re making sure we have lots of support for all of our people to grow at Monzo. We are an equal opportunity employer. All applicants will be considered for employment without attention to age, ethnicity, religion, sex, sexual orientation, gender identity, family or parental status, national origin, veteran, neurodiversity or disability status.
