Senior Software Engineer - Computational Life And Health Sciences

IT IS, together with its partner organizations Schmid & Partner Engineering AG (SPEAG), ZMT Zurich MedTech AG (ZMT), and TI Solutions AG (TI Solutions), form the Zurich43 alliance. Z43 s dedicated mission is to expand the knowledge and technology in three key areas:

• Characterization, optimization, and application of the electromagnetic (EM) near-field
• predictive modeling of interactions between physical agents and physiology in complex anatomies
• medical applications that bridge fundamental research with real-world impact

At the heart of this mission lies Sim4Life, the world s leading simulation platform that unites physics, biology, and engineering in a single framework. Researchers use Sim4Life to model the human body, medical devices, and their interactions, enabling science and innovation that truly matter.

To strengthen our team, we are looking for a talented developer with a strong background in C++ and Python. If you enjoy working on complex systems and want to help bring cutting-edge desktop simulation technology into a modern, web-based environment, this position is for you.

Your challenges:

This role will take you deep into the heart of our simulation platform and your work will touch many areas: feature development, infrastructure, performance, and scientific workflows. You will be:

• Extending and adapting our large C++/Python code base for the web
• Designing and maintaining scalable, asynchronous services for communication and data exchange across our distributed simulation platform
• Maintaining and integrating a wide range of third-party libraries and solvers, while ensuring our build and continuous integration pipelines remain stable and efficient
• Supporting performance improvements, deployment strategies, and container-based architectures

Your strengths:

• At least three years of solid experience with C++ and Python, and know how to handle large, long-lived code bases
• You are curious, well-organized, and comfortable switching between different layers of the stack: from low-level performance optimization to cloud deployment
• Ideally, you already have hands-on experience with some of the technologies we use: boost, pybind, aiohttp/FastAPI, WebSockets, REST, WebRTC, ZeroMQ, make/CMake, Docker based containerization or Gitlab CI/CD pipelines
• You understand modern asynchronous design patterns and are motivated by applying your engineering skills to complex problems in computational science
• Basic knowledge of the AWS cloud stack is a plus as our platform is hosted entirely on AWS
• Strong sense of responsibility and commitment to the highest quality standard of work
• Self-motivation, good organizational and communication skills, impeccable attention to detail, friendly personality, and team-spirit
• Ability to manage multiple tasks simultaneously, to work independently in a fast-paced setting, and to meet tight deadlines
• Commitment to effectively respond to the needs of partners and customers
• Proficiency in English (both written and spoken), ability to communicate in German is a plus

Our offer:

• Vibrant, multicultural, and innovative work environment that drives key technologies and fosters diversity and inclusion
• State-of-the-art laboratories, high-performance computing clusters, and production facilities
• Creative mix of global talents that span the fields of physics, electronics, mathematics, biology and more, striving for excellence and high ethical standards
• Flexible working hours at a workplace in the heart of Zurich

Applications will be accepted until the position is filled. Direct applications are preferred; applications submitted via recruitment agencies are discouraged. Please note that incomplete applications will be disregarded.

Please send your application documents (in English) consisting of motivational letter, tailored CV (max 2 pages), diplomas, transcripts (with grades), work certificates and/or reference letters (if available) to:
