Digital Mock-Up & Mechanical Engineer

As a DMU & Industrial Engineer, you will be the backbone of our engineering execution chain, from digital mock-up management and configuration control to detailed part design, drawings and hands‑on industrial support. This is a polyvalent, roll‑up‑your‑sleeves role for someone who thrives on variety: one day you maybe structuring the DMU and managing configuration baselines, the next you’ll be designing a bracket or fixture, producing manufacturing drawings, or working alongside technicians on the shop floor to solve an integration problem. You will join the team at a critical stage: building a full‑scale demonstrator with flight testing. You will work closely with the CTO and the entire engineering team.

Key responsibilities:

Digital Mock-Up (DMU)& Configuration Management

• Own and maintain the product DMU (Fusion 360): structure the assembly tree, manage parts and sub‑assemblies, ensure spatial integration and clash‑free design across all disciplines.
• Enforce configuration management processes: naming conventions, versioning, change management (Engineering Change Requests / Orders), baseline control and traceability throughout the product lifecycle.
• Act as the central point of reference for the digital product definition, ensuring consistency between design, manufacturing and testing configurations.

Design & Drafting

• Perform detailed mechanical design of components, assemblies, fixtures, tooling and test equipment, from concept sketches through to fully dimensioned 3D models and 2D manufacturing drawings.
• Serve as an expert for colleagues designing proprietary components, guiding them on design choices, manufacturability.
• Apply GDT (Geometric Dimensioning & Tolerancing) and aerospace drawing standards to produce clear, unambiguous technical documentation.
• Collaborate with stress, thermal and fluid engineers to translate analytical requirements into manufacturable part designs.
• Support manufacturing and assembly activities on the shop floor: advise on fabrication methods, resolve fit‑up issues, validate first articles and accompany parts from drawing release to installation.
• Contribute to the definition of assembly sequences, tooling requirements and industrialization plans for prototypes and products.
• Interface with suppliers and sub‑contractors on technical specifications, manufacturing feasibility and quality requirements.
• Participate in test bench assembly, sub‑system integration and aircraft integration activities as needed.

Required profile:

• Graduate of a top engineering school or holder of a Master’s degree in energy engineering, propulsion, or mechanical engineering.
• 3 to 8 years of experience in a demanding industrial environment: aerospace, space, energy, motorsport or defense, combining CAD/DMU work, detailed design and shop‑floor involvement.

Required skills and qualities:

• Strong proficiency in CAD tools for 3D modeling, assembly management and drawing production.
• Solid understanding of configuration management principles and tools (change management, baselines, part numbering, BOM management).
• Mastery of GD&T, drawing standards and manufacturing tolerancing.
• Hands‑on mindset: comfortable working on the shop floor, using hand tools, and solving practical integration and fabrication problems.
• Proven versatility: ability to switch between digital design office work and industrial/workshop activities with equal effectiveness.
• Rigor, analytical mindset and strong organizational skills.
• Knowledge of / sensitivity to aerospace requirements and standards.
• Excellent written and oral communication skills in both French and English.
• A unique opportunity to join a fast‑growing startup at an early stage and contribute to high‑impact, innovative projects by developing responsible and sustainable technological solutions.
• Take part in building the Viraj Aero team and spirit from the ground up
• Work in a dynamic environment with rapid prototyping projects and regular interaction between R&D, design, and testing teams.
• Opportunity to contribute to patents or technical publications and play a key role in the evolution of emerging technologies
• Be at the heart of breakthrough technological developments that will shape the future of aviation, with strong opportunities for professional growth and advancement.
