Senior Design Engineer

Stellenbeschreibung:

Overview

In this role you will own the gearbox design for SRAM eBike and bicycle drivetrains, from concept to series release, combining deep gear-design expertise with hands-on execution. You will work in a small, fast-moving team to evaluate concepts, optimize gear trains, and collaborate with system architects, motor, electronics, and software teams. Expect hands-on prototyping, supplier collaboration, and risk mitigation to deliver robust, production-ready gearboxes. This is an impact role to shape high-volume eBike transmission solutions at SRAM.

Verantwortungsbereiche

Own the design and development of gearbox solutions for eBike and bicycle drivetrain applications (gear stages, shafts, bearings, freewheels, housing interfaces)
Evaluate and select gearbox concepts based on package, efficiency, noise, weight, and cost targets
Perform gear and drivetrain calculations and optimization using KISSsoft/KISSsys (load capacity, service life, micro-geometry, efficiency, NVH)
Define gearbox architecture in alignment with system architects and other teams
Create and maintain 3D models and production-ready 2D drawings with GD&T and tolerance stacks
Plan and build prototypes, support test setups, validation, and failure analysis
Collaborate with gear suppliers and manufacturing partners on DFM, sampling, quality, and cost
Mitigate technical risks via FEA, DFMEA, and tolerance analysis
Drive problem resolution within the design team and with factories and suppliers
Document design specifications using SRAM best practices and standard procedures
Contribute to manufacturing processes, heat treatment, and inspection methods for gears
Contribute to gearbox development methods, design guidelines, and tools
