Mechanical Design Engineer (Process Equipment)

Mechanical Design Engineer (Process Equipment)

Company Overview

OCSiAl is the world’s largest manufacturer of single-wall carbon nanotubes. Founded in 2010 with

headquarters in Luxembourg, the company is the first and, so far, the only company in the world to have developed an industrial and scalable technology for producing this unique material.

OCSiAl operates a production facility for carbon nanotube synthesis in Serbia and is currently running three parallel projects for the construction of new production complexes in Serbia and Luxembourg. To support this expansion, the company is seeking experienced engineers to strengthen its project department.

Description

We are looking for a Mechanical Design Engineer with strong CAD skills to join our in-house equipment development team. In this role, you will design components and assemblies for gas-processing equipment, translating process requirements into practical mechanical solutions. You will work closely with process and engineering teams, taking ownership of assigned equipment components from concept through detailed design. This position is ideal for an engineer who combines solid design fundamentals with hands-on industrial thinking.

Responsibilities

This is a junior to mid-level mechanical design role focused on 3D modelling, detailing, and development of equipment components and assemblies. The role supports process design, engineering coordination, and project execution activities, working under the guidance of senior engineers. It does not own overall project management or procurement processes but contributes technical deliverables and supports equipment design and documentation.

1. Mechanical Design & Equipment Development

Prepare equipment requirements and design briefs for processing equipment.

Develop concept proposals and detailed designs for components and subassemblies under the guidance of senior engineers.

Develop equipment layouts, 3D models, fabrication drawings, bills of materials, and design specifications for assigned scope.

Select appropriate materials, fittings, and welding methods.

Ensure compliance with European and international engineering standards.

2. Technical Documentation & Design Quality

Create and maintain detailed 2D/3D designs using SolidWorks, Inventor or Siemens NX.

Develop technical documentation, including fabrication drawings, specifications, and reports.

Prepare technical packages for manufacturing and supplier inquiries.

Apply knowledge of welded joints, flange connections, and pipe fitting techniques.

Ensure quality control according to European welding standards.

3. Engineering Integration & Project Support

Work closely with engineers from other disciplines (process, electrical, and automation).

Provide technical support during project execution and commissioning phases.

Participate in technical reviews and design optimizations.

Provide technical support for equipment and component selection during the procurement

process.

Review vendor drawings and incorporate approved comments.

Work closely with manufacturing and assembly teams during fabrication and assembly, collecting

feedback from shop-floor personnel, welders, and technicians.

Analyse manufacturing and assembly feedback, identify recurring design issues, and implement

necessary design adjustments under the guidance of senior engineers.

Document lessons learned from fabrication and assembly activities and translate them into

recommendations for future equipment designs, modernisation, and optimisation initiatives.
