Senior Software Engineer - Technical Lead

**Senior Software Engineer / Technical Lead** First software hire on a clinical AI product automating 3D tumor quantification and tracking — with a direct path to technical lead. **The company** CarcinoQuant is founded by professors Joel Kullberg and Håkan Ahlström — part of the team behind Antaros Medical, which they recently exited. Building on 15 years of imaging research at Uppsala University, they are now commercializing patented technology that automates whole\-body tumor quantification from CT, moving from 2D diameter measurements to comprehensive 3D longitudinal tumor tracking. The product will imply a quantum leap in accuracy for clinicians and drug developers alike. **The role** You will own the full software stack: a backend service layer connecting our AI models to clinical workflows, a user\-friendly clinical UI for radiologist review in clinical practice and manual correction of segmentation results, and DICOM\-based PACS integrations including patient data de\-identification gateways. The product will be a regulated medical device — data security and auditability are top concerns. As the team grows, this role moves into a technical lead function with direct influence over architecture, tooling, and hiring. The AI engine and compilation of ground through falls outside scope of this role.  **What we are looking for** * Senior full\-stack SW\-development background with production experience in backend services and data\-intensive UIs. * Experience in regulated environments — ideally with experience from Software as a Medical Device. * Familiarity with DICOM and medical imaging workflows. * Maturity to operate with high autonomy and grow into a technical lead role. **Practicalities** * Location : Uppsala, Sweden but with substantial flexibility for remote work. * Compensation : In addition to a competitive salary, we encourage skin in the game and offer option based incentive programs. **Contact** If you are ready to join, send a summary of your relevant experience (CV) to wenzel.nisshagen@carcinoquant.com Our data privacy policy will be provided upon initial contact.
