About the role
Work Schedule Standard (Mon-Fri) Environmental Conditions Office Job Description
At Thermo Fisher Scientific , our Ion Chromatography & Sample Preparation (ICSP) division is building the next generation of laboratory instruments, and we're looking for an experienced Senior C#/.NET Developer to help shape the software behind them.
Make an Impact
This is a unique opportunity to join a strategic New Product Introduction (NPI) program focused on developing an entirely new platform for ion chromatography instruments.
Rather than enhancing legacy products, you'll help replace a platform built on more than 15 years of electronics with a modern, scalable architecture designed for the future. Working at the intersection of software and hardware, you'll develop the software that powers high-precision analytical instruments used by scientists around the world.
This multi-year program offers long-term stability and the opportunity to contribute throughout the entire product lifecycle—from architecture and design to validation and commercialization.
What You'll Do
Design & Develop Instrument Software Design and develop software components that enable reliable communication, control, and data acquisition for laboratory instruments. Build and maintain instrument drivers and low-level software components. Translate product and system requirements into scalable, maintainable software solutions. Develop using modern technologies including C# and .NET 10 .
Drive System Integration Collaborate closely with hardware, firmware, and systems engineers to define interfaces and integration points. Support seamless integration between instrument software and higher-level applications. Participate in technical design discussions and architectural decisions.
Deliver Quality & Reliability Implement robust diagnostics, logging, and error handling. Participate in testing, verification, and validation activities. Follow secure software development practices and quality standards aligned with regulated environments.
Solve Complex Technical Challenges Investigate and troubleshoot issues spanning software, firmware, and hardware. Contribute to code reviews and continuously improve engineering practices and development tools. Help ensure long-term maintainability, scalability, and product evolution.
What We're Looking For
Strong software development experience using C#/.NET (experience with .NET 10 is an advantage). Experience developing software that interfaces directly with hardware, including device drivers, embedded software, or instrument control systems. Solid understanding of modular software architecture and maintainable design principles. Knowledge of communication protocols and hardware interfacing concepts. Experience developing multi-threaded or concurrent applications. Strong debugging and problem-solving skills across software and hardware interactions. Experience working in cross-functional engineering teams including hardware, firmware, systems, and software. Familiarity with structured development processes; experience in regulated or quality-driven environments is a plus. Excellent communication skills in English. A passion for building reliable, high-quality software and continuously improving engineering practices.
Why Join Us? Work on a true greenfield platform rather than maintaining legacy software. Influence the architecture of next-generation scientific instruments. Collaborate with multidisciplinary engineering teams solving complex technical challenges. Contribute to products that support scientific research, healthcare, and innovation worldwide. Be part of a long-term strategic program with opportunities to grow alongside the product from concept to market.
