Fullstack Job Details

Onfido is the new identity standard for the internet. We empower people around the globe to reach services they love and need simply, speedily and safely – whether they’re renting a car or opening a bank account or completing a high-value transaction where identity is key. We built 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’ awards at CogX.

Onfido is an established pre-IPO technology company with a prominent position in the global marketplace that has been repeatedly recognized for excellence in performance and innovation. In 2021 we were awarded ‘Artificial Intelligence and Machine Learning Hot Company’ by CyberDefense Global Infosec Awards, ‘Fraud Prevention Innovation of the Year’ at the CyberSecurity Breakthrough Awards, and named to the CB Insights Fintech 250 for the fourth year running. We've received over $200 million in funding from investors including TPG Growth, Microsoft, and Salesforce to achieve our vision. We partner with thousands of businesses to help millions access services every week – from billion dollar institutions to hypergrowth unicorns. We support identities from 195 countries, and 2,500+ document types. Our recent growth is fuelled by continued increasing demand in the United States – where we’ve grown in year-over-year sales by 264% – as more enterprise organisations accelerate their digital transformation plans with Onfido.

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!

Essential Experience

  • Experience in software engineering, regardless of the language. We prefer to match with candidates that have the mindset we seek and then provide space for individuals to pick-up the required technology (again, flexibility is key here).
  • System design, architecture, design patterns, object oriented programming, cloud native architectures.
  • We value engineers who have a strong product-centric mindset.
  • Lean/Agile process. We want you to be involved in all phases of the development lifecycle and bring your unique talents to the process.
  • Brilliant team player - communicate and collaborate well with product owners, designers, developers, test engineers and people outside the team.
Tech Stack
“I get it; you are flexible about technology skills, but what stack do you use?”

  • Backend: mostly Python and Ruby
  • Frontend: React and Typescript
  • ML: Tensorflow, Jupyter, Dask
  • Kubernetes and Docker for deployment
  • AWS for underlying infrastructure (Aurora, Redis, Dynamo, S3, SNS, SQS, CloudFront, API Gateway, etc.)
  • Gitlab for software lifecycle management.

We are technology agnostic at Onfido. We are not looking for you to have experience in all these technologies. As long as you're open to learn, please apply.
