Job Description

The Position

Thermo Fisher Scientific's Ion Chromatography and Sample Preparation (ICSP) team is seeking a C# Engineer to 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 a multi-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 maintain backend 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

Implement automated testing strategies and practice test-driven development

Support CI/CD pipelines and follow modern DevOps practices for build, integration, and deployment

Ensure secure 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, including AI-assisted development , to improve speed, quality, and knowledge sharing

Qualifications & Skills

Strong experience in backend software development (C# mandatory; C++/Python also relevant)

Solid understanding of object-oriented design, data structures, and algorithms

Experience developing modular, maintainable, and scalable software systems

Experience with version control systems (e.g., Git) and modern development workflows

Familiarity with CI/CD pipelines, automated testing, and DevOps practices

Experience working in agile development environments (SAFe is a plus)

Understanding of distributed 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 leveraging AI-assisted development tools to improve productivity and quality

Degree in Computer Science, Software Engineering, or a related field (or equivalent experience)
