About the role

Key responsibilities & impact

Overall technical leadership and responsible for realization of full systems product release to ensure quality and compliance.
Define the system imaging performance targets (spatial resolution, low‑contrast detectability, noise texture, CT number accuracy, temporal resolution) based on clinical use cases and regulatory benchmarks.
Define the system‑level software architecture for CT scanners, including real‑time control, data acquisition, image reconstruction, post‑processing, and hospital integration (DICOM).
Define failure handling and recovery strategies for software‑detectable faults (e.g., lost sync, DAS buffer overrun, communication timeouts).
Translate clinical and product requirements into detailed software system specifications, interface contracts, and performance budgets (latency, throughput, uptime).
Lead trade‑off analyses for software partitioning: on‑scanner vs. offline processing, CPU vs. GPU vs. FPGA, real‑time OS vs. general‑purpose OS.
Develop and maintain physics‑based models of the imaging chain: X‑ray spectrum, detector response (including photon‑counting or integrating modes), scatter, beam hardening, and electronic noise.
Establish objective and subjective image quality metrics (MTF, NPS, contrast‑to‑noise ratio, artifact severity scales) and standard operating procedures for system evaluation. Design and execute phantom‑based and cadaver/clinical studies to validate algorithm performance across patient sizes, anatomical regions, and scan protocols.
Collaborate with clinical partners and radiologists to collect feedback and iteratively improve image appearance and diagnostic value.
Perform system trade‑off analyses (dose vs. resolution, scan speed vs. image noise, slice thickness vs. artifacts) and document design rationales.
Translation of user and business needs into product requirements.
System decomposition and allocation of derived IQ related requirements to component level and related traceability.
Trade-off of system design specifications and interfaces, determine feasibility of potential solutions, and leading technical & design reviews.
Managing complexity of products or systems in multi-disciplinary setting, within scope of a single business.
Leads and influences others and drives design for quality and is closely involved in the program of the applicable business.
Makes a fundamental contribution to the innovation of products or processes.
Solves fundamental problems on the basis of thorough (unique) knowledge in the professional field.
Generates initiatives with regard to technological improvements, and performs future-oriented studies in dialogue with other specialists.
Makes substantial contribution to the innovation process and communicates new insights to own business.
Specialist in business and solves complex problems, where responsible for the overall concept at systems level. Closely involved in policy preparation.
SW/IQ defect management

Requirements

What you’ll need

PhD or Master’s in Medical Physics, Biomedical Engineering, Electrical Engineering, Physics, SW engineering, computer science and technology or a related field.
Minimum 6–10 years of industry experience in CT SW design or imaging system development, with a proven track record of delivering clinically successful image quality.
Deep understanding of the complete CT SW design or imaging chain: X‑ray generation, beam shaping, signal detection, data acquisition, reconstruction, and post‑processing.
Proven track record of bringing at least one CT product from concept to regulatory clearance/market launch.
Proven experience leading technical reviews and guiding multi‑disciplinary teams.
Strong written and verbal communication; ability to present complex data to senior management.
Fluent in English (technical documentation and global collaboration).
Familiarity with system modeling languages (SysML) or requirements management tools (DOORS, Jama).
