A specialized medical technology company is seeking a Senior Backend Developer to build services supporting medical imaging, clinical workflows and real-time data delivery to extended-reality devices. You will work primarily with C# and Python, make architectural decisions, develop production-grade APIs and services, and operate within a regulated quality environment. The role is offered in a hybrid setup in Germany or Poland.
Highlights
Build backend services for medical imaging and clinical workflows in a regulated software environment. The role combines C# and Python development, real-time data streaming, architecture ownership and close collaboration with XR, clinical and quality teams.
Description
apoQlar builds Mixed and Augmented Reality software for medicine with the HoloMedicine® platform - a certified medical device (EU MDR, IEC 62304, ISO 13485).
Behind the spatial experience on the headset sits a backend that ingests medical imaging, orchestrates clinical workflows and streams data to XR devices in real time.
We are a small, focused team working directly with clinics and partners such as the Mayo Clinic.
Location Hamburg/Hybrid or Poznan/Hybrid
Tasks
As Senior Backend Developer you own the services that power HoloMedicine® behind the scenes: imaging pipelines, clinical orchestration (e.g.
our Tumor Board management plane), real-time streaming and the platform APIs that XR clients depend on.
You write production-grade C# and Python, make sound architectural calls, and keep everything traceable and release-ready in a regulated environment - working closely with XR engineering, clinical stakeholders and Quality/Regulatory.
Design, build and operate backend services in C# / .NET and Python - APIs, data pipelines and integration services
Work on medical imaging backends: DICOM / DICOMweb, NIFTI handling
Support real-time data flows to XR clients - reliability, latency and session stability
Containerize and ship via Docker / Kubernetes, including workflow orchestration (e.g.
Argo Workflows) and CI/CD
Build for observability and security from day one: structured logging/metrics (Grafana / Prometheus / Loki), SBOM/SOUP hygiene (Dependency-Track, Trivy, CycloneDX)
Keep work compatible with MDR / IEC 62304 / ISO 13485 - requirements, risk linkage and traceability, in alignment with Quality/Regulatory
Review code, mentor peers and help shape backend architecture and engineering standards
Requirements
Must-have
Several years' professional experience building backend services in C# / .NET, plus solid working command of Python
Strong grasp of API design, distributed systems and data modeling — you can reason about architecture, trade-offs and performance as a peer
Hands-on with containers and cloud (Docker, Kubernetes; Cloud a plus)
Comfortable with relational and/or document databases, async messaging and integration patterns
Pragmatic about testing, CI/CD and code quality
Knowledge of medical imaging / DICOM / DICOMweb / FHIR / NIFTI
Fluent in English; German is a plus
Nice-to-have
Experience with regulated medical software (EU MDR, IEC 62304, ISO 13485, ISO 14971)
Real-time media / streaming experience (WebRTC, TURN/ICE)
Familiarity with observability stacks (Grafana/Prometheus/Loki) and SBOM/security tooling (Dependency-Track, Trivy, CycloneDX)
Exposure to XR/AR/VR platforms or a clinical environment
