About Corintis

Corintis offers innovative microfluidic cooling technologies for AI chips/GPUs and CPUs used in data centres. Working with many of the world’s largest tech companies, our solutions improve compute sustainability and tackle the excessive electricity consumption associated with data centre 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 75 people from over 25 nationalities to solve the most significant computing challenges of tomorrow. Based in the EPFL Campus in St. Sulpice, we are closely connected to the local ecosystem and are located a few minutes walk from Lake Geneva.

The Role

We’re looking for a hands-on Prototyping Technician/Engineer to support and develop our in-house manufacturing capabilities for next-generation microfluidic cooling solutions for HPC and AI systems.
We need a hands-on, versatile prototyping technician/engineer capable of coordinating and executing prototype builds across multiple manufacturing processes, bridging internal development and external suppliers to accelerate product iteration and validation.

Responsibilities of The Role

• Own and coordinate end-to-end prototyping activities
  Plan, execute, and track prototype builds across in-house capabilities and external suppliers, ensuring parts are delivered on time and meet technical requirements.

• Manage external suppliers for prototype manufacturing
  Prepare RFQs, align on technical specifications, follow up on production, and ensure quality and lead time compliance for CNC machining, additive manufacturing, and other outsourced processes.

• Support hands-on prototyping and assembly
  Participate directly in building, assembling, and testing prototypes, including basic machining setups, fixture preparation, and integration of components.

• Contribute to process development and optimization
  Support the development, validation, and improvement of prototyping processes to enhance speed, repeatability, and reliability across different manufacturing technologies.

• Perform metrology and part validation
  Inspect and validate prototype parts using standard metrology tools, ensuring compliance with drawings and functional requirements; provide structured feedback to improve designs and processes.

• Interpret technical drawings and define requirements
  Work closely with engineering teams to review drawings, define tolerances, and ensure manufacturability of parts across different fabrication methods.

• Develop documentation and standardization
  Create and maintain SOPs, work instructions, and process documentation, ensuring knowledge capture and repeatability of prototyping workflows.

• Plan and track prototyping schedules
  Coordinate timelines across internal teams and suppliers, identify risks or delays, and proactively adjust plans to meet project milestones.

• Drive troubleshooting and iterative improvement
  Support root cause analysis of prototype issues and drive fast iteration cycles, balancing speed and quality in a development environment.

• Collaborate cross-functionally
  Work closely with R&D, manufacturing, and external partners to ensure alignment, smooth execution, and continuous improvement of prototyping activities.

• Support integration of new technologies (plus)
  Contribute to the evaluation and onboarding of new prototyping technologies (e.g., laser processing, metal AM, CNC) as capabilities expand.

Requirements

• End-to-end prototyping ownership
  Ability to coordinate and execute prototyping activities both in-house and with external vendors, ensuring timely delivery and quality of parts.

• Vendor coordination & follow-up
  Experience working with external vendors (CNC machining, AM, finishing, metal joining (eg brazing), etc.), including RFQ and Work-Order management, technical alignment, and delivery tracking.

• Manufacturing process knowledge
  Solid understanding of CNC machining, grinding, turning, metal joining processes (e.g. brazing), basic assembly methods, tightening & clamping, and jigs/fixtures design, with practical awareness of manufacturing constraints and tolerances.

• Hands-on prototyping experience
  Comfortable working in a lab/workshop environment, with direct involvement in building, assembling, and testing prototypes.

• Technical drawing & metrology
  Ability to read and interpret technical drawings, define critical dimensions, and apply basic metrology methods to validate parts.

• Process documentation & standardization
  Experience preparing SOPs, work instructions, and process documentation to ensure repeatability and knowledge sharing.

• Planning & execution mindset
  Strong capability in planning prototyping activities, coordinating schedules, and prioritizing tasks in a fast-paced environment.

• Problem-solving & iteration
  Structured approach to troubleshooting, root cause analysis, and iterative development, balancing speed and quality.

• Cross-functional collaboration
  Ability to work closely with engineering, operations, and external partners, ensuring alignment across all stakeholders.

• Additional technical exposure (plus)
  Experience with laser technologies and/or metal additive manufacturing is a strong plus, along with any exposure to liquid cold plates or cooling systems.

This is a great fit if you:

• You enjoy hands-on work with cutting-edge equipment and precision manufacturing.

• You want to develop expertise in laser processing, microfabrication, and advanced prototyping.

• You like solving practical technical challenges and contributing directly to product development.

• You thrive in fast-moving environments where you can learn quickly and have impact.

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

• You prefer purely theoretical or desk-based work.

• You are not comfortable working hands-on with machines in a lab/production environment.

• You prefer highly rigid processes instead of iterative prototyping workflows.

• You are not interested in learning new technologies or adapting to evolving equipment capabilities.

• You cannot work on-site in Lausanne
