About the job
MVision AI is a health-tech company building AI-driven and cloud-based solutions to streamline
radiotherapy workflows. Headquartered in Helsinki, with its flagship product Contour+ in operation
across EMEA, APAC, and the Americas, MVision develops Workspace+, a comprehensive platform aiming to serve radiotherapy departments globally. Ranked #16 in Deloitte Fast 50 Finland, we are a
mission-driven team at the frontier of AI in Radiation Oncology.
THE ROLE
This is a full-time Senior Backend Engineer role based in Helsinki, with a hybrid work arrangement that allows some work from home.
You will be a key engineer on the cloud platform behind Contour+ and Workspace+ — the services that move clinical imaging, run AI contouring workloads, and control who can access what. Customer
demand is growing fast and this role exists to scale our platform to embrace the future.
You will own backend services end to end, with identity management, multi-tenant data, and security
at the centre of the work. The role sits within R&D and works closely with DevOps, Customer Success, and regulatory teams.
Key Responsibilities
Cloud Backend Development
- Design, build and operate backend services in .NET and Python across cloud and on-premises
deployments
- Own services end to end — architecture, implementation, testing, deployment and production
behaviour
- Improve performance, reliability and scalability as customer volume grows
Identity & Access Management
- Build federated SSO so hospitals can authenticate with their own identity providers (Azure AD, AD FS, SAML, OIDC)
- Develop multi-tenant authorization and customer onboarding that scales without an engineer in the loop
- Integrate and operate an OIDC identity broker across our applications
Multi-Tenant Data
- Design and evolve multi-tenant schemas with strict tenant isolation
- Plan and execute migrations on live data that cannot be taken offline
Security & Compliance
- Treat authentication, secrets management, audit trails and least privilege as first-class design
concerns
- Uphold patient data protection across every service — no PHI in logs, anywhere
- Contribute to MDR/ISO 13485 and security documentation alongside the code
Internal Collaboration
- Work with DevOps on deployment and observability, and with Customer Success on issues surfacing
from hospital environments
- Contribute to internal design documentation, architecture decisions and engineering standards
