Mechanical Engineer

Oratek, an engineering consulting company based in Ecublens, Switzerland, is seeking a skilled and detail-driven Mechanical Engineer to join our multidisciplinary team.

Founded in 2018, Oratek delivers precision equipment and engineering services to demanding industries, with a strong footprint in precision industry. Our team thrives on small-scale, high-finish challenges where rigor and attention to detail are non-negotiable.

As a Mechanical Engineer at Oratek, you will design small benchtop machines and precision equipment — typically tabletop systems integrating fine mechanics, motion, actuators, sensors and electronics — for some of the most demanding clients in Switzerland. This is machine design at small scale, not pure micro-mechanics: you'll be architecting full systems (frame, kinematics, integration) as much as designing individual precision parts. You'll work alongside electronics, firmware, software and system engineers in a tight, collaborative environment.

If you take pride in precision and want to work where every micron and every surface finish matters, we'd like to hear from you.

## Tasks

• Design small benchtop machines and precision equipment: overall architecture, frame, kinematics, integration of actuators, sensors and electronics.
• Design, prototype and validate small-scale precision mechanical assemblies and components.
• Produce manufacturing-ready 2D plans with full tolerancing (ISO / GD&T) for fine machining and plastic injection.
• Iterate designs to converge on the optimal balance of cost, manufacturability, finish, and performance.
• Specify materials, surface treatments and finishes appropriate for high-end applications (watchmaking and similar).
• Collaborate with electronics, firmware, software and system engineers to define technical requirements.
• Follow up with machining and injection-molding partners; validate first articles and production batches.
• Prepare technical documentation: drawings, BOMs, assembly instructions.
• _(Nice to have)_ Contribute to electrical schematics and the wiring/assembly of electrical cabinets.

## Requirements

• Degree in Mechanical Engineering or Microtechnology (HES / EPF), or a CFC followed by additional training and substantial relevant experience.
• Minimum 4 years of experience in precision mechanical design — ideally in high-finish industries (watchmaking, medical, aerospace instruments, scientific instruments).
• Hands-on experience designing for both fine machining and plastic injection molding.
• Proficiency with Fusion 360 (or strong CAD background and willingness to adopt it).
• Strong rigor in producing complete manufacturing drawings with proper tolerancing.
• Solution-oriented mindset: able to iterate and propose alternatives rather than declare a problem unsolvable.
• Strong attention to detail.
• Working proficiency in French; English a plus.
• Nice to have: basic electrical schematic skills and ability to wire/assemble electrical cabinets — apprenticeship level fully acceptable.
• 100% on site in Ecublens (VD).

## Benefits

• A stimulating and innovative work environment.
• Opportunities for professional development and continuous training.
• Competitive salary and attractive social benefits.
• Opportunity to work on diverse and exciting projects.
• Access to cutting-edge technologies and advanced technical resources.
• A collaborative and dedicated team.

Join Oratek as a Mechanical Engineer and collaborate with a visionary, multidisciplinary team in Switzerland. Contribute to precision-engineering projects for some of the most demanding industries in the world, in a dynamic, small-company environment.
