Job Description

The Position

Thermo Fisher Scientific's Ion Chromatography and Sample Preparation (ICSP) team is seeking aC# Engineerto contribute to the development of next-generation ion chromatography laboratory instruments.

This role is part of a strategic NPI (New Product Introduction) initiative focused on developing a new generation platform for chromatographic instruments. This is not about maintaining or incrementally improving existing solutions, but a complete redesign of a system currently built on approximately 15-year-old electronics.

The goal is to create a modern, scalable platform by leveraging new technologies to significantly improve performance, functionality, and overall system architecture. The work involves developing backend components for embedded user interfaces (eUI), enabling robust communication, control, and data handling for high-precision analytical instruments.

This is amulti-year program, offering long-term stability and the opportunity to contribute across multiple phases of development—from early architecture through to commercialization.

What will you do?

You will design and develop backend software components for embedded systems, contributing to scalable, secure, and maintainable software architecture.

Backend Development & Architecture

• Design, develop, and maintainbackend components for embedded UI systems using modern C#
• Apply object-oriented design principles, design patterns, and strong data structures to build maintainable solutions
• Contribute to architectural discussions and technical decision-making

System Integration & Collaboration

• Collaborate with architects, firmware, DevOps, and test engineers to deliver integrated software solutions
• Translate complex technical and scientific requirements into robust implementations
• Support integration across embedded, firmware, and higher-level application layers

Quality, Security & DevOps

• Implementautomated testing strategies and practice test-driven development
• Support CI/CD pipelines and follow modern DevOps practices for build, integration, and deployment
• Ensuresecure coding practices aligned with regulatory and cybersecurity requirements

Delivery & Continuous Improvement

• Participate in agile development processes (including SAFe where applicable)
• Work independently on complex problems while supporting and mentoring less experienced engineers
• Contribute to continuous improvement of code quality, development processes, and tooling

Innovation & Productivity

• Leverage modern tools, includingAI-assisted development, to improve speed, quality, and knowledge sharing

Qualifications & Skills

• Strong experience inbackend software development (C# mandatory; C++/Python also relevant)
• Solid understanding ofobject-oriented design, data structures, and algorithms
• Experience developingmodular, maintainable, and scalable software systems
• Experience withversion control systems (e.g., Git) and modern development workflows
• Familiarity withCI/CD pipelines, automated testing, and DevOps practices
• Experience working inagile development environments (SAFe is a plus)
• Understanding ofdistributed systems or embedded environments is an advantage
• Strong analytical and problem-solving skills with ability to handle complex requirements
• Strong communication skills in English
• Interest in leveragingAI-assisted development tools to improve productivity and quality
• Degree in Computer Science, Software Engineering, or a related field (or equivalent experience)
