YPAI, empresa noruega de datos para IA, busca especialistas en radioterapia para contornear estudios de TC y RM seudonimizados (validación de IA). 100 % remoto, pago por hora como profesional independiente. Detalles en inglés a continuación; se requiere inglés escrito suficiente para seguir un protocolo.

We are hiring clinicians and planning professionals who routinely contour organs at risk in radiotherapy workflows: medical dosimetrists, treatment planners, RTTs and medical physicists. You contour OARs on head and neck and brain CT and MRI, a radiation oncologist reviews every case, and the contours become the expert reference set used to validate a radiotherapy auto-contouring product. First project: 10 to 40 hours over 2 to 4 weeks, remote, on your own schedule, with further projects for contourers who deliver well.

### The work

- Organs at risk on pseudonymised planning CT, and on MRI where the protocol asks for it; mainly head and neck and brain.
- Protocol first; where it is silent, Brouwer 2015 for head and neck OARs and the EPTN atlas for brain. TG-263 structure names.
- Two calibration cases before production. A radiation oncologist reviews every case independently; you correct after review and log any protocol question.
- Cases come in batches from a small, named panel; volume and turnaround are agreed per project.

### Who we are looking for

- Qualified dosimetrist, treatment planner, RTT or medical physicist who contours OARs as part of clinical work.
- Head and neck and/or brain planning experience.
- Any treatment planning system or research contouring tool; onboarding in the project platform is provided.
- Written English good enough to follow a protocol and log decisions.

### How the work runs

- Fully remote, flexible hours, as an independent contractor. Open to specialists living in Latin America (countries listed on this page).
- Confidentiality and project-specific data handling requirements apply, and you sign them before any access.
- If your employment contract requires approval for outside work, please arrange it before you accept a project.

Our team reviews applications for this role and contacts selected applicants by email.
