Top Tech Jobs & Startup Jobs in San Francisco Bay Area, CA

Own supplier industrialization for wire harness and FPC/FFC assemblies from advanced development through mass-production qualification. Provide design-for-manufacturing guidance, assess supplier readiness, audit manufacturing processes, verify capacity, resolve supplier-caused quality issues, lead corrective actions, and support manufacturing quotations. Partner with engineering teams and contract manufacturers to improve quality, cost, responsiveness, and process efficiency.

Designs, builds, commissions, and maintains electric-motor dynamometer systems for characterization, supplier inspection, and durability testing. Owns complete test-system lifecycles, including requirements, mechanical and electrical integration, controls, instrumentation, data acquisition, safety, automation, documentation, and operations. Develops standardized software workflows, motor test datasets, supplier-deployable inspection systems, and application-representative load profiles. Collaborates with motor design, reliability, power electronics, controls, manufacturing, and supplier-quality teams while providing technical guidance to engineers, technicians, and suppliers.

Develop and industrialize electric motor and stator winding processes from prototype through production. Design tooling, fixtures, gauges, and automated equipment; conduct experiments, process trials, validation, and root-cause investigations. Establish process specifications, capability studies, inspection methods, and manufacturing documentation. Collaborate with engineering, quality, operations, and suppliers on equipment development, factory acceptance testing, technology selection, production transfer, and ramp-up. The role requires substantial hands-on work in labs, prototype areas, and manufacturing environments.

Develop and own features for Zipline’s consumer mobile and web applications, using React Native, Python, and Go. Interns will collaborate cross-functionally on customer-focused features, contribute to technical roadmaps and engineering practices, and work across design, deployment, and iteration. This is a full-time, in-person internship in South San Francisco from January through April 2027.

Design and deploy perception algorithms for autonomous aircraft and obstacle detection, localization, and tracking. Build machine learning training pipelines, evaluation frameworks, debugging tools, and visualization systems. Collaborate with systems, flight-test, and validation teams to improve safety-critical detect-and-avoid capabilities. Apply deep learning, geometric computer vision, simulation, and real-world operational feedback to improve accuracy, latency, and robustness in complex environments.

Develop and test autonomous flight-control algorithms, simulations, analysis tools, and onboard integrity tests. Analyze flight data for regressions and improvements, assess vehicle performance and safety, and present results to engineering teams. The internship involves embedded software, technical computing, hardware interaction, and real-world aircraft systems at Zipline’s South San Francisco or Dallas offices.

Supports the Flight Controls team by designing, implementing, testing, and releasing flight-control algorithms for autonomous aircraft. Develops simulation, controls analysis, integrity-testing, and regression-protection tools; analyzes flight data for performance improvements; evaluates safety and reliability; and presents engineering results.

Develop and own hardware test assets for drone systems, from requirements and implementation through validation, data collection, troubleshooting, analysis, and engineering recommendations. Collaborate with cross-functional teams to test circuit boards, avionics, sensors, power systems, mechanical assemblies, and integrated subsystems. Build mechatronic systems and automation scripts, streamline testing and reporting, and ensure component performance, reliability, and safety.

Lead supplier industrialization for PCBA and top-level assemblies, including DFM, supplier selection and audits, process validation, quality improvement, capacity planning, SCARs, SPC, NPI support, and automated testing. Partner with engineering, supply chain, contract manufacturers, and manufacturing teams to improve yield, efficiency, and defect reduction while ensuring IPC, ISO, automotive, and aerospace standards compliance. The role is based in South San Francisco and requires 30–40% global travel.

Design, prototype, test, and validate electrical systems for autonomous drone delivery platforms. Projects may include battery charging electronics, ground-support electronics, production test equipment, avionics validation, reliability testing, and root-cause investigations. Collaborate with mechanical, embedded, software, systems, manufacturing, and operations teams to develop reliable solutions for real-world deployment.
