We are looking for a Mechanical Process Design Engineer to join our teams in Switzerland and support mechanical and process design engineering for biotech manufacturing facilities and GMP process systems. The position is a permanent contract and a consultant role within our Life Sciences experts (not a contractor).

Your Responsibilities

- Design and engineer GMP process systems and mechanical equipment for biotech facilities (Drug Substance and/or Drug Product), from concept through detailed design and execution support.
- Develop process and mechanical design deliverables: PFDs, P&IDs, equipment datasheets, line lists, valve lists, tie-in lists, piping specs, and user requirements inputs in line with GMP expectations.
- Perform sizing and selection of process equipment and components (tanks/vessels, heat exchangers, pumps, filters, valves, instrumentation interfaces), ensuring hygienic design and maintainability.
- Engineer clean/sterile utilities distribution and process piping, including material selection, slope/drainability, dead-leg minimization, hygienic connections, and support for CIP/SIP philosophy.
- Define and review layout and 3D model constraints with piping and building disciplines: equipment arrangement, accessibility, maintenance envelope, routing, and constructability.
- Coordinate technical interfaces with automation/instrumentation, HVAC, electrical, civil/structural, QA, and operations, ensuring requirements are captured and design is consistent across disciplines.
- Support project execution: vendor technical alignment, RFQs and bid evaluations, design reviews (HAZOP, GMP review), FAT/SAT preparation and attendance, and site support during installation.
- Contribute to commissioning & qualification (C&Q) readiness by ensuring design traceability to requirements, supporting punch-list closure, and providing technical input for IQ/OQ documentation.
- Apply EHS and process safety practices (risk assessments, pressure equipment considerations, ATEX where relevant), ensuring compliant and safe mechanical solutions.
- Ensure documentation quality and inspection readiness: controlled drawings, as-built updates, technical dossiers, and change control support.

Your Profile

- Degree in Mechanical Engineering, Process Engineering, Chemical Engineering, or equivalent.
- Proven experience in mechanical/process design engineering for biotech / biopharma facilities under GMP constraints.
- Strong command of process piping and equipment design, including hygienic design principles (e.g., drainability, cleanability, materials, surface finish, dead legs).
- Solid experience with P&IDs, datasheets, equipment specification, vendor coordination, and multidisciplinary design interfaces.
- Familiarity with CIP/SIP, single-use vs. stainless steel considerations, and typical biotech process equipment is highly valued.
- Experience supporting project phases (Basic Design, Detail Design, Construction, Commissioning) and working with EPCM/engineering partners is a plus.
- Fluent German (C1/C2) and professional English level for global project environments and documentation.
- Structured, hands-on, and comfortable working both in design offices and on-site during execution phases.
