Onfido lets people prove their identity anytime, anywhere. We’re creating a more open digital world by connecting them to the services they love and need simply, speedily and safely – whether they’re renting a car or opening a bank account. We’re building a full-service suite of AI-powered identity verification solutions with fairness and inclusiveness at their core, and were awarded ‘Outstanding Leader in Accessibility’ and ‘Best Innovation in Algorithmic Bias Mitigation’ and ‘Best AI product in FinTech’ awards at CogX

We are a global, established, technology company having surpassed $130M in annual recurring revenue (ARR) with a prominent position in the global marketplace, and have been repeatedly recognized for our performance and innovation. In 2023, we’ve been awarded ‘Best Fraud Detection and Prevention Company of the Year by Frost & Sullivan, featured as a Strong Performer by Forrester in its 2022 Identity Verification Wave, and named to the CB Insights Fintech 250 for the fourth year running. We've received over $200 million in funding from investors such as TPG Growth, Microsoft, and Salesforce to achieve our vision. We partner with hundreds of businesses to help millions access services every week – from billion dollar institutions to hypergrowth unicorns. We support checks in 195 countries, and 2,500+ document types. With over 1,200 customers worldwide and 500 employees

Our goal is to work together to promote and celebrate an inclusive and diverse community. Collectively, all Onfidoers are committed to creating an environment where everyone can be themselves, and where differences are celebrated. We encourage people from all backgrounds and cultures to come together to solve some of the world's most interesting problems.

We are looking for a full-stack engineer who is passionate about solving interesting problems and genuinely enjoys the craft of programming. We don’t expect a master of all trades, but someone more experienced in backend or frontend who is flexible enough to hop to the other side if needed, and who is able to reason about complete end-to-end software architectures. A T-shaped, well-rounded, software engineer that doesn’t see themselves fitting into a small very well defined box.

We’re a closely knit team who tackle challenges together - expect a lot of pair programming and rich discussions in code reviews. We have a cultural strong bias for action, like to move fast, adjust, adapt, then reflect and seek ways to improve every day. Experience working in a Lean environment is desired, and we want help to drive the shipment of well tested software frequently. TDD and good testing practices are highly valued here. As a senior engineer you’ll get to mentor and guide the more junior team members while growing your own career with the support of mentors and coaches throughout the business.

Be open to learning new things, owning topics, experimenting with new ideas, technologies and pioneering new discoveries that nobody else has thought of yet. We would love to welcome a creative and enthusiastic problem solver to join us as we achieve big things!

    • System design, architecture, design patterns, object oriented programming, cloud native architectures.

    • Solid web experience would be great, with a strong understanding of React and other architectural frameworks
    • Experience with both functional and object-oriented programming
    • Experience working on projects supporting multiple devices/browsers
    • Up-to-date with the latest Web features
    • Test automation experience
