Missão
Company: Segula Technologies
Location: Initial onboarding in Ciudad Sahagún, Hidalgo (with transition to Remote once the project stabilizes)
Work Modality: Hybrid / On-site to Remote
About Segula Technologies
Segula Technologies is a global engineering group serving all major industrial sectors, including automotive, aerospace, energy, rail, naval, pharmaceutical, and oil & gas. Operating in more than 30 countries with 140 offices worldwide, we put innovation at the heart of our strategy, driving large-scale projects from initial studies through to industrialization and production.
Role Overview
We are looking for Senior Mechanical CAD Designers to join our engineering team and support international rolling stock and heavy manufacturing projects. In this role, you will be responsible for developing 3D mechanical models and 2D technical drawings based on conceptual guidelines from Lead Designers, ensuring all components and assemblies meet strict technical and manufacturing standards. Note on Work Modality: This position requires an initial on-site phase in Ciudad Sahagún, Hidalgo, for onboarding and project alignment, transitioning to a remote setup once the work package is stabilized.
Key Responsibilities
- 3D Modeling & 2D Drafting: Develop detailed 3D mechanical models of parts and assemblies, as well as accurate 2D manufacturing drawings using CATIA V5.
- Component & Assembly Design: Design, modify, and optimize mechanical components and structural assemblies following lead engineer concepts and client specifications.
- Standards & Manufacturability: Apply technical standards, geometric dimensioning and tolerancing (GD&T), and Design for Manufacturing (DFM) criteria across all deliverables.
- Documentation & Change Management: Manage technical documentation, bills of materials (BOMs), and engineering design modifications within PLM environments.
- International Collaboration: Coordinate daily with multidisciplinary engineering teams in North America (Canada) to align on technical requirements, schedules, and project milestones. Required
- Education: Bachelor’s degree in Mechanical Engineering, Mechatronics Engineering, Industrial Design, or a related technical field.
- Experience: 5+ years of proven experience in mechanical product design, components, and complex assemblies.
- Software Mastery: Advanced proficiency in CATIA V5 (Part Design, Assembly Design, Generative Shape Design, Drafting).
- Industry Background: Solid experience in the Railway / Rolling Stock sector (preferred), or equivalent experience in Automotive, Heavy Vehicles, Aerospace, or Industrial Manufacturing (specifically involving structural components, chassis, body-in-white, or mechanical systems).
- Language: Upper-intermediate to advanced English (B2+) with the ability to hold technical conversations and coordinate directly with international teams.
Current residence in or willingness to temporarily relocate/commute to Ciudad Sahagún, Hidalgo (e.g., candidates based in Pachuca, Querétaro, CDMX, or surrounding areas) during the initial project phase.
Perfil
- Strong knowledge of GD&T (Geometric Dimensioning and Tolerancing).
- Familiarity with manufacturing processes such as welding, riveting, bolting, sheet metal, and industrial painting.
- Experience working with PLM systems such as ENOVIA, Teamcenter, or 3DEXPERIENCE.
- Opportunity to work on high-impact, international engineering projects with global teams.
- Flexible transition to a remote work model following the initial on-site integration phase.
