Senior Backend Developer (.NET / C#)

We are looking for a Senior Backend Developer to join the 3Shape Cloud Storage team.

The team builds, maintains and evolves the services responsible for moving, storing and synchronizing business-critical data across dental clinics, laboratories and cloud environments worldwide.

The Cloud Storage service runs locally alongside the dental applications in the clinics and labs, and in the cloud. It supports automatic synchronization of data to where it is needed. The Cloud Storage also stores data in the cloud for the clinics and labs with adequate subscriptions. To give an idea of scale, 3TB of data is ingested daily, with 120 million events processed daily and 1.9 petabytes of data stored globally.

We are intentionally prioritizing strong software developers over cloud specialists. If you have deep C#/.NET expertise and solid engineering fundamentals, we can help you learn the Azure-specific and SRE parts of the role. Experience with cloud platforms, Azure, DevOps, Infrastructure as Code or SRE practices is valuable, but a solid software engineering foundation is what matters most.

You will design, develop and maintain backend services that power one of 3Shape's core platform capabilities. You will combine backend development with SRE, Infrastructure as code and DevOps to work on distributed systems, data synchronization challenges, scalability, reliability and performance across a large production environment. The role involves end-to-end delivery of features—from development and testing to deployment readiness and stakeholder alignment.

You also have experience with SQL, both high-level and detailed monitoring, including building and maintaining dashboards and managing multi-region deployment pipelines. Additionally, familiarity with PKI infrastructure, certificate chains and Merkle trees is considered a strong advantage.

You will collaborate with platform and product teams across 3Shape to align on Azure standards and best practices, especially around Infrastructure as Code, observability and operational readiness.

You are a strong software developer who values pragmatic engineering, continuous improvement, and collaboration. You thrive in agile teams and take ownership, from code quality and design to operational outcomes in production. Candidates with strong software engineering backgrounds and an interest in cloud technologies are encouraged to apply.

If this sounds like a great match for your experience and interests, we’d love to hear from you. Please apply with your CV and a short motivation.
