Senior Software Engineer, User Authentication

We are looking for an experienced Senior Software Engineer to join the User Authentication Platform team and help shape the future of secure, seamless authentication experiences across our apps. This involves exciting product challenges, such as implementing frictionless multi-factor authentication flows or building security features that empower our users to control their trusted devices and sessions, all with an end goal of providing a smooth and secure experience to our 200M+ global customers

With over 200 million customers in 50+ countries, Bolt is one of the fastest-growing tech companies in Europe and Africa. And it's all thanks to our people.

We believe in creating an inclusive environment where everyone is welcome, regardless of race, colour, religion, gender identity, sexual orientation, age, or disability.

Our ultimate goal is to make cities for people, not cars, and we need your help to achieve this mission!

As a Senior Software Engineer, you will be responsible for architecting, designing, developing, and deploying backend solutions that improve our user authentication platform. That will mostly happen via coding in Node.js and TypeScript (PS: no previous experience with Node.js is needed).

You will be closely collaborating with key internal stakeholders to determine how to scalably design backend systems and APIs to meet their needs. Engineers at Bolt have a heavy inclination towards product thinking, so you will get a chance to shape up and drive exciting product initiatives yourself, in partnership with your peer Product Manager.
