R&D Tooling Engineer — Lab Fixtures & Jigs

Harmattan AI; Paris; Sur place; EUR 60 000 - 90 000; Plein temps

Résumé du poste

Harmattan AI in Paris is seeking a Mechanical Engineer for the R&D Hardware Tooling team. You will design and build internal lab fixtures, jigs, rigs, and bench structures, owning the mechanical side end-to-end.

You will work at the intersection of mechanics, electronics, and development across every Harmattan hardware program, prioritizing precision, repeatability, and fast in‑house fabrication. The role emphasizes hands‑on ownership in a small team with limited process, and requires SolidWorks

Qualifications

• Engineering degree in Mechanical Engineering, Mechatronics, Consumer Electronics, or equivalent.
• Proven experience designing lab or development fixtures, jigs, or rigs — or a track record of shipping physical products with a desire to build the tools behind them.
• Proficiency in SolidWorks, including complex assembly modelling and 2D drawings with GD&T.
• Hands‑on experience with rapid prototyping and in‑house fabrication (3D printing, CNC, off‑the‑shelf framing systems).
• Ability to integrate electronics and instrumentation into fixtures and enclosures with reliable measurement access.
• Strong instinct for tolerancing, repeatability, and fixture accuracy; comfortable working to tight positional constraints.
• Experience with mechanism and actuation design (clamping, alignment, pneumatic) is a strong plus.
• Basic FEA and thermal/CFD to validate designs is a nice‑to‑have.
• Appetite for ownership and fast iteration — a maker who gets hands dirty, works independently, and thrives in a small team without heavy process.

Responsabilités

• Design fixtures, jigs, enclosures, and bench structures in SolidWorks with full integration of electronics and instrumentation, maintaining complete 2D drawings with GD&T to guarantee fixture precision and repeatability.
• Design clamping, alignment, and actuation mechanisms — manual and pneumatic — for repeatable, ergonomic positioning of prototypes during bring-up and characterisation.
• Build fixtures rapidly in-house (3D printing, CNC, aluminium framing) and via quick-turn suppliers; iterate fast based on hands‑on validation with the tooling hardware and software engineers.
• Own the development of bench and lab fixtures, environmental and reliability validation rigs, instrument/DAQ enclosures, RF/antenna characterisation mechanics, and modular bench structures for the R&D teams.
• Validate fixture repeatability, durability over many cycles, and operator ergonomics; use basic FEA and thermal/CFD where required (e.g. environmental rigs) to confirm designs.
• Manage quick‑turn machining and printing suppliers; specify framing hardware and drive procurement with Supply Chain.
• Define and maintain a modular, reusable fixture‑mechanics standard across product teams, directly reducing bring‑up time and improving characterisation repeatability.
• Maintain fixture designs, drawings, build instructions, and maintenance records as the single source of truth for the team.
