Why join us

TRACTIAN is transforming the industrial world by empowering frontline maintenance workers to achieve more. We’ve fused cutting-edge hardware with innovative software into one powerful platform, disrupting legacy systems and delivering smarter, faster solutions for our clients.

As a

Mechanical Design Engineer

, you will transform concepts into robust mechanical designs by creating precise 3D models and detailed drawings that guide manufacturing and assembly. You will apply GD&T principles to ensure functional accuracy and tolerance compatibility, collaborating with engineers, suppliers, and manufacturing teams to deliver designs that balance performance, cost, and reliability.

Responsibilities

  • Develop 3D models and 2D drawings using CAD tools, ensuring accuracy and manufacturability.

  • Apply GD&T (Geometric Dimensioning and Tolerancing) to control critical dimensions and guarantee functional fit.

  • Translate engineering concepts and requirements into clear technical documentation.

  • Review designs for compliance with standards, tolerances, and best practices in mechanical engineering.

  • Collaborate with product engineers, analysts, and manufacturing teams to resolve design challenges.

  • Maintain CAD libraries, templates, and drawing standards to streamline workflows.

  • Support prototype builds and provide design updates based on test and validation results.

  • Prepare technical packages for suppliers and ensure alignment with production capabilities.

  • Collaborate with hardware, firmware, quality, and manufacturing teams to align technical decisions with product reliability and compliance.

  • Deliver clear reports and presentations summarizing risks, mitigation plans, and their impact on product design and lifecycle.

Requirements

  • Bachelor’s degree in Mechanical Engineering, Industrial Engineering or Related Field

  • Strong proficiency with CAD software (SolidWorks, NX, CATIA, or similar).

  • Hands-on experience with GD&T and tolerance stack-up analysis.

  • Knowledge of manufacturing processes (machining, injection molding, casting, etc.).

  • Ability to create detailed technical drawings and documentation for suppliers.

  • Strong understanding of mechanical assemblies, fit, and function.

  • Attention to detail and commitment to high-quality standards.

  • Good communication skills and ability to collaborate in multidisciplinary teams.

  • Proactive, self-directed learner who drives issues to closure.

  • Advanced English level.

  • Live in or have availability to move to São Paulo.

Bonus points

  • Proficiency in Blender (or equivalent 3D modeling/rendering software) and CAD tools.

  • Experience with high-aesthetic standard injected products, including in-depth knowledge of plastic injection molding processes and technical application details. 

  • Familiarity with PLM systems and design-for-manufacturing methodologies.

COMPENSATION

  • • Competitive salary and stock options

  • • Optional fully funded English / Spanish courses

  • • 30 days of paid annual leave

  • • Education and courses stipend

  • • Employee Giving

  • • Earn a trip anywhere in the world every 4 years

  • • Up to R$1.000/mo for meals and remote work allowance

  • • Health plan with national coverage and without coparticipation

  • • Dental Insurance: we help you with dental treatment for a better quality of life.

  • • Gympass and Sports Incentive: R$300/mo extra if you practice activities

If you want to build a ship, don't organize people to collect wood, assign them tasks, and give orders. Instead, teach them to long for the vast and endless sea.
