Each project invitation states the work, your pay, what the pay covers and what the work must meet. You see it before you accept.

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 Australia or New Zealand.
- 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.
