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

Design, build, commission, and improve mechanical test equipment for battery and power electronics validation. Responsibilities include structural design, actuation systems, FEA and hand calculations, safety systems, CAD documentation, supplier management, and integration with instrumentation, controls, and automation to enable repeatable lab testing and manufacturing validation.

Partner with SG&A leaders to improve organizational effectiveness: guide hiring, performance, promotions, coach managers, handle employee relations, support L&D and People Ops, and reinforce culture.

Lead ground test strategy for the droid and its interaction with pickup infrastructure. Design, build, and operate mechanical test fixtures, life-test rigs, and environmental test systems; develop instrumentation and Python automation for data collection and evaluation; drive test campaigns from prototype to production; triage cross-domain failures and support suppliers and manufacturing ramps.

Lead end-to-end mechanical design for battery and power distribution hardware from requirements through production. Design enclosures, busbars, and housings to meet structural, thermal, EMI, and manufacturability requirements; perform analyses (FEA, tolerance stacks, hand calculations), create production CAD and drawings, develop and execute verification tests, qualify suppliers, and provide technical leadership or mentorship.

Lead performance and reliability test campaigns for motors, propulsion systems, and actuators. Design and execute electromechanical, thermal, and structural tests; analyze failures; validate models and FEA; develop automated data-acquisition and production test strategies; collaborate with mechanical, electrical, firmware, and manufacturing teams.

Lead a small backend team to build and operate the Financial Platform that converts operational events into auditable financial records. Own billing, settlements, ledgers, reconciliation, ERP integrations, SLOs/SLIs, incident response, and audit readiness. Drive roadmap with Finance, deliver measurable reconciliation and close-time improvements, ensure correctness for payments and inventory costing, and be a hands‑on manager shipping code and technical designs.

Own end-to-end commodity strategy and supplier performance for mission-critical hardware. Lead sourcing, supplier selection, contracts, qualification, ramp-to-volume, cost-down, risk mitigation, and supplier dispute resolution. Integrate with engineering and operations, set measurable targets (cost, OTD, PPM), run supplier audits and QBRs, and travel to supplier sites for on-site engagement and recovery.

Build and maintain event-driven backend and full-stack systems that convert operational events into auditable financial records. Implement billing, settlements, reconciliation, ERP integrations, and reliable APIs with strong focus on idempotency, ordering, failure recovery, and financial correctness. Partner with finance and domain teams, automate manual workflows, own observability and production runbooks, and mentor engineers while participating in on-call rotations.

Design, train, and deploy large-scale computer vision and perception models (semantic segmentation, 4D geometry, preference models) for cloud and on-prem systems. Build data pipelines, annotation and evaluation tooling, validate models for field reliability, and ship production-grade features frequently. Senior roles lead architecture and experimentation; Staff roles own roadmaps for offboard perception models.
