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

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.

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.

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.

Lead antenna architecture, design, simulation, prototyping, integration, and validation for airborne and ground products. Perform EM simulation, lab and chamber measurements, field testing, production test design, and supplier/manufacturing integration. Solve system-level RF issues, support regulatory/certification, and mentor engineers to deliver robust production antenna systems across multiple radio technologies.

Lead structural analysis for Zipline aircraft: own and validate GFEM/DFEMs, perform rapid hand calculations and FEM studies, support certification and test correlation, lead failure investigations, mentor contributors, and support field/flight tests to improve reliability, mass, and fleet availability.

Lead architecture, design, integration, validation, and production of highly integrated multi-radio RF front-end systems for aircraft and ground platforms. Define RF architectures supporting LTE/5G, GNSS, Wi‑Fi, ADS‑B/UAT, Bluetooth, ISM, V2V; perform RF system analysis, coexistence mitigation, antenna-sharing and MIMO strategies; develop lab validation and production test methods; support certifications and supplier/manufacturer integration; mentor engineers and establish RF design standards and roadmaps.

Lead RF desense and electromagnetic shielding architecture across Zipline platforms. Analyze, mitigate, validate, and productionize receiver desense solutions for multi-radio systems (LTE/5G, GNSS, Wi‑Fi, ADS‑B, Bluetooth, ISM). Develop shielding strategies, perform lab and flight testing, define design standards, support certification, collaborate across disciplines, and mentor engineers to ensure robust RF coexistence and GNSS performance in production products.

Lead systems engineering for safety-critical electromechanical autonomous systems. Own requirements, decomposition, interface definition, verification, test coverage, and validation. Drive cross-disciplinary trade studies, set performance/safety/cost budgets, evaluate release and test standards, and partner with design and certification teams to prove flight worthiness to regulators.

Own and deliver end-to-end embedded subsystems for long-range aircraft: firmware, drivers, runtime, and monitoring. Implement flight- and safety-critical code on microcontrollers (bare-metal/RTOS), lead validation (HIL/bench/field), build deterministic test and telemetry tooling, and triage high-severity field incidents until fleet metrics confirm resolution.

Build and maintain a high-performance simulation platform and deterministic digital twins that integrate with flight, cloud, and embedded software. Scale simulation from single-vehicle debugging to fleet-scale CI testing, enable HIL and developer tooling, and partner with cross-functional teams to validate safety-critical autonomous flight logic and system integration.
