Senior Software Engineer

Corintis offers innovative microfluidic cooling technologies for AI chips/GPUs and CPUs used in data centers. Working with many of the world’s largest tech companies, our solutions improve compute sustainability and tackle the excessive electricity consumption associated with data center cooling, which consumes more electricity than New York and London combined.

Ranked as the No.1 Engineering startup in Switzerland for 2025, Corintis offers a friendly and team-oriented workplace, bringing together over 50 people from over 25 nationalities to solve the most significant computing challenges of tomorrow. Based on the EPFL campus near Lausanne, we are closely connected to the local ecosystem and are located a few minutes walk from Lake Geneva.

Key Responsibilities:

• Design, develop, and implement large-scale software projects. 

• Write clean, efficient, and well-documented code primarily in Python.

• Work collaboratively with cross-functional teams to define, design, and ship new features.

• Provide guidance and support to junior developers, aiding in their professional development.

• Ensure the performance, quality, and responsiveness of applications.

• Identify and correct bottlenecks and fix bugs.

• Continuously discover, evaluate, and implement new technologies to maximize development efficiency. 

Requirements:

• Bachelor's degree in Computer Science, Engineering, or a related field.

• 5+ years of professional software development experience.

• Extensive experience with Python and familiarity with its ecosystems.

• Demonstrated experience in building large, complex software systems.

• Strong familiarity with industry-standard design patterns and best practices.

• Fluent in English, with strong communication skills.

• Solid understanding of the full software development life cycle.

• Experience in multiple programming languages and paradigms is a plus.

• Knowledge of HPC systems is a plus.

• Experience with simulation and modeling software systems is a plus. 

This is a great fit if you:

• Enjoy building large-scale software systems end to end and take pride in clean, maintainable Python code.

• Enjoy mentoring junior engineers and contributing to a collaborative, team-first culture.

• Can work full-time on-site in Lausanne.

This won’t be the right role for you if:

• You’re uncomfortable working in a fast-moving startup where priorities can evolve quickly.

• You’re early in your career and don’t yet have experience with large, complex software systems.

• You prefer minimal collaboration and don’t enjoy cross-functional teamwork with hardware, research or scientific teams.
