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

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 systems engineering to define product capability roadmaps, decompose architectures, create verification plans, and validate safety-critical autonomous aircraft systems. Mentor the team, align cross-functional interfaces, optimize tradeoffs among safety, performance, and cost, and partner with safety and regulatory teams to prove flight worthiness.

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.

Support Operations Finance by analyzing large operational datasets, building financial models and dashboards, forecasting, performing variance and KPI analysis, and partnering with operations to improve cost, efficiency, and scaling. Assist month-end processes and contribute to cross-functional initiatives and process automation.

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.

As a Perception Intern, you'll work on ML model experimentation, evaluate and integrate solutions for perception challenges in drone delivery, collaborating with the Droid Perception team.

Contribute to system-level validation of Zipline's Zip, Droid, and Dock by building and executing automated HIL and flight tests, developing test pipelines and scripts, diagnosing hardware/software issues, and collaborating with cross-functional engineers to improve reliability and safety of the autonomous logistics system.
