Composite Technician - Airframe in Lausanne

ph3bAbout Us /b /h3pHarmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. /ppOur work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected. /ph3bAbout the role /b /h3pAs the composite technician on the Airframe team, your core mission is to bprototype carbon structures fast, in-house /b — from mould to finished, quality-checked part — and to bring binnovative solutions that make assembly and prototyping easier /b. A true hands-on professional, you combine technical skills, initiative, and a maker mindset. You build tooling, lay up and finish composite parts (carbon / glass fibre), and turn the engineers' CAD into flight-worthy structures on short cycles. You are also the bowner of technical drawings and supplier quotations /b for the parts you handle, and the one who btrains production operators /b when a design moves to series. You thrive with minimal supervision, favour pragmatic, quick-result approaches over perfect-but-slow tooling, and are equally comfortable laying up a part, machining or printing a mould, and reading a technical drawing. /ph3bTechnical skills /b /h3h3bKey responsibilities /b /h3pRapid in-house prototyping (core) /pullipProduce carbon prototype structures quickly in-house, choosing the fastest viable route rather than heavy tooling when a proto is the goal. /p /lilipPropose innovative, simple solutions to speed up assembly and prototyping. /p /lilipDesign certain parts and prototyping tools yourself (fixtures, adapters, simple structural parts) when it is faster than going through the design loop. /p /lilipIterate fast with the design engineers: short loops between concept, part and feedback, flagging manufacturability issues before they cost a mould. /p /li /ulpTooling moulds /pullipBuild and maintain moulds and tooling, in coordination with the design team; machine or 3D-print mould masters, prepare and polish mould surfaces. /p /lilipDesign and build layup jigs, trimming templates, bonding and assembly fixtures. /p /lilipManage the composite workshop consumables and material inventory (fabrics, resins, cores, vacuum consumables) including storage and shelf-life follow-up. /p /li /ulpDesign documentation /pullipRead and interpret 2D/3D drawings and ply books; model simple parts and tooling in CAD when needed; give manufacturability feedback early. /p /lilipOwn the technical drawings: produce and keep up to date the manufacturing drawings for the parts and tooling you handle. /p /lilipWrite and maintain clear, accessible fabrication procedures, ply books and cure logs on Confluence so processes are repeatable by others. /p /lilipOptimise part designs for their manufacturing process: adapt geometries for bplastic injection /b (wall thickness, draft angles, ribs) or for bcomposite / 3D-printed fabrication /b (layup feasibility, demoulding, printability), in collaboration with the design engineers. /p /li /ulpSupport improvement /pullipSupport assembly and mechanical testing, including preparing test coupons and samples for structural analysis. /p /lilipIdentify and propose process and quality improvements; help run the composite workshop safely (dust extraction, PPE, resin handling and waste management). /p /lilipOwn the knowledge transfer to production: train the production operators on fabrication and assembly processes, and validate that a process is repeatable by others before handover. /p /li /ulh3bCandidate profile /b /h3ullipTechnical diploma or degree in composite materials, mechanical / aerospace manufacturing, industrial technology, or equivalent hands-on experience. /p /lilipbProven experience in rapid in-house composite prototyping /b (carbon / glass fibre): hand layup, vacuum bagging, infusion and/or prepreg; mould making and surface preparation a strong plus. /p /lilipTrack record of bquick, pragmatic solutions /b — getting a functional carbon part out fast, with sound trade-offs, rather than perfect parts requiring heavy tooling. /p /lilipAbility to read technical drawings and ply books, and to control layup orientation, resin ratios, debulking and cure cycles with rigour and traceability. /p /lilipAbility to bproduce manufacturing drawings (2D plans) /b /p /lilipUnderstanding of bdesign-for-manufacturing basics /b for plastic injection (wall thickness, draft angles) and composite / 3D-printed parts, to optimise geometries with the design engineers. /p /lilipHands-on finishing skills: trimming, sanding, drilling composites, structural bonding, insert fitting, and basic defect detection (porosity, delamination). /p /lilipProficiency with common fabrication tools (hand tools, bench equipment, 3D printer; basic machining appreciated); CAD literacy (Fusion 360, SolidWorks, FreeCAD or similar) to adapt tooling and jigs. /p /lilipHighly autonomous — able to take ownership of tasks and drive them to completion with minimal supervision; resourceful and solution-oriented, comfortable improvising with available means. /p /lilipbPedagogy and communication /b: able to write clear, accessible procedures and to btrain production operators /b so processes remain repeatable without you; rigorous on process, safety and documentation. /p /li /ulpWe look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI. /p /p #J-18808-Ljbffr
