Senior Mechanical Design Engineer

STARK is a new kind of defence technology company revolutionising the way autonomous systems are deployed across multiple domains. We design, develop and manufacture high performance unmanned systems that are software-defined, mass-scalable, and cost effective. This provides our operators with a decisive edge in highly contested environments.We’re focused on delivering deployable, high-performance systems—not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe—todaySTARK is a new kind of defence technology company revolutionizing the way autonomous systems are deployed across multiple domains.

In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe—today.Your missionAs our Senior Mechanical Design Engineer, you will own the mechanical architecture of STARK’s next-generation UAV platforms from concept to high-rate production. You will set technical direction, mentor engineers, and work closely with cross-functional teams to deliver highly reliable, certifiable, and field-deployable systems under aggressive timelines.You will both define mechanical design strategy and dive deep into CAD, tolerance stacks, and Design for Manufacture/Assembly (DFMA) prototypes. You will act as the company’s authority on mechanical design for airframes and payload integration, influencing platform-level decisions and ensuring designs are robust, scalable, cost-effective for mass production, and certifiableResponsibilitiesLead mechanical design for UK current and future UAV platformsDefine and enforce best practices for parametric modeling, GD&T, and tolerance stack-upsDrive airframe material selection, structural layout, and manufacturability decisionsOversee supplier engagement for structural components, composites, and assembliesCollaborate with stress, flight test, and systems teams to ensure structural integritySupport and occasionally lead design reviews with leadership, partners, and certifying authoritiesBe hands-on with CAD (SolidWorks/CATIA), prototyping, and shop-floor troubleshootingLead mechanical design for UK current and future UAV platforms, focusing on design-for-manufacture (DFM) and high-rate production methods.Define and enforce best practices for parametric modeling, GD&T, and tolerance stack-ups, with an emphasis on production efficiency.Drive airframe material selection, structural layout, and manufacturability decisions for scalable production.Oversee supplier engagement for structural components, composites, and assemblies, ensuring adherence to high-volume production standards.Collaborate with stress, flight test, and systems teams to ensure structural integrity while optimising designs for mass production.Support and occasionally lead design reviews with leadership, partners, and certifying authorities, presenting trade-offs for production scale.Be hands-on with CAD (SolidWorks/CATIA), prototyping, and shop-floor troubleshooting, with a focus on process and design optimisation for rate increase.QualificationsMechanical design experience, in aerospace / UAVProven record of taking structures from concept through verification to high rate production (wing, fuselage, empennage)Expert in SolidWorks (CATIA V5/V6 a plus) and tolerance stack analysisStrong knowledge of composites, 3D printing, machining, injection moulding, and joining methodsFamiliarity with MIL standards and EASA/FAA certification pathways (SC-Light UAS, CS-23)Excellent communication skills — able to influence at exec and program levelEligible for UK Security Clearance
