Sinch is pioneering the way the world communicates. More than 150,000 businesses — including Google, Uber, PayPal, Visa, Tinder, and many others — rely on Sinch’s Customer Communications Cloud to power engaging customer experiences through mobile messaging, voice, and email.
Whether you need to verify users or craft omnichannel campaigns, Sinch makes it easy. Our AI-infused Super Network, APIs, and applications ensure you can connect with your customers reliably and securely, at every step of their journey.
At Sinch we “Dream Big”, “Win Together”, “Keep it simple”, and “Make it Happen”. These values are our foundation!
The Role
Our Onboarding team owns how new customers sign up to Sinch and get verified (KYC). It is the very first experience every customer has with us, so it needs to be fast, simple, and secure.
As a Backend Software Engineer III, you will build and run the services behind these sign-up and verification flows. You will join a small Stockholm-based team alongside a Senior full-stack Tech Lead and a full-stack engineer, as we grow a permanent team that takes full ownership of the product.

Develop and deploy microservices on Kubernetes, using Docker and CI/CD pipelines.
-
Contribute to the distributed systems that power customer sign-up and verification.
-
Write clean, tested, maintainable code using sound design patterns.
-
Take part in code reviews and pull requests, and help raise code quality across the team.
-
Own the features you build from design through to production.
Follow a build-ship-run approach.
What We Are Looking For
-
3–4+ years of backend development experience.
-
Experience with Node.js (TypeScript is a plus).
-
Experience building REST APIs.
-
Good knowledge of SQL databases (PostgreSQL, MySQL, or similar).

Hands-on experience with Kubernetes.
