About the role:
We are looking for a mechanically robust Lead Engineer – Mechanical with 5 to 6 years of experience to lead our product development team. You will own machine programmes end to end - from concept definition and hand calculations through detailed CAD models, engineering drawings, prototype builds, field validation, and release to production. Beyond your own design work, you will set the technical direction for the team, review and sign off the calculations and drawings of junior engineers, and be accountable for whether the design works in the field. You will be expected to think analytically, justify decisions with numbers, and iterate quickly based on real-world feedback.

Roles and Responsibilities:
Own the mechanical design of complete agricultural machines and lead their development from concept through production release: structural frames, drive systems, conveyor mechanisms, cutting assemblies, and collection systems
Define design architecture and specifications at the concept stage - establish load cases, duty cycles, safety factors,



and design targets before detailed work begins
Perform and review engineering calculations to size components and validate designs before fabrication: forces, torques, stresses, deflections, fatigue, and power requirements; act as the technical check on the team's calculation sheets
Develop 3D models and detailed manufacturing drawings using parametric CAD; apply GD&T; for fabrication clarity, and review the models and drawings released by the team
Guide component selection - bearings, chains, sprockets, fasteners, seals, motors - using manufacturer catalogues and relevant IS / BS / ISO standards, and standardise part selection across machines
Mentor and technically supervise junior design engineers: allocate design work, run design reviews, and build the team's analytical discipline
Work directly with the fabrication workshop and external vendors to resolve manufacturing constraints, drive design for manufacture a
