Top Tech Jobs & Startup Jobs

Own and operate commerce platform services end-to-end: merchant portals, partner integrations, marketplace policy, billing/settlements, and fulfillment tooling. Drive reliability, SLOs, incident response, cross-functional launches, partner onboarding, observability, and mentor engineers while ensuring financial correctness and scalable production systems.

Develop, validate, and own cell- and pack-level battery models (SPM/SPMe/P2D and equivalent circuit) and electro-thermal models. Design and analyze EIS, HPPC, OCV, and aging test campaigns. Build battery state estimation and charging/aging-aware algorithms and integrate models into simulation and fleet software. Lead cell selection and vendor benchmarking and collaborate cross-functionally to deploy validated models into operations.

Lead technical sales and site solution design, managing site delivery from evaluation through construction, permitting, commissioning, and initial operation. Coordinate customers, contractors, AHJs, utilities, and internal teams; source and manage contractors; mitigate risks; and translate field constraints into prioritized product improvements to accelerate future ground systems rollouts.

Lead a 5–9 person aerodynamics team to define and deliver aerodynamic and aeroacoustic performance for Zipline vehicles. Own CFD/modeling, experimental testing (wind tunnel, flight-test), propeller trade studies, release-quality geometry, and aero health metrics. Interface cross-functionally to drive design, validation, manufacturability, and operational performance with regular domestic travel for flight tests.

Lead multidisciplinary mechanical, electrical, test, and technician teams to take the Dropbox electromechanical hardware from architecture through validation, production intent, and scalable deployment. Own system-level tradeoffs, risk management, test planning, supplier/manufacturing handoff, field reliability, and cross-functional partnerships while hiring, coaching, and operating the hardware organization's processes and launch readiness.

Own outbound shipments from order release through carrier handoff. Pick, stage, verify, and package serialized and high-value parts. Prepare shipment documents, coordinate pickups, complete ERP/WMS transactions, resolve inventory discrepancies, and partner across teams to protect traceability and ensure on-time deliveries.

Lead end-to-end flight test campaigns for autonomous delivery aircraft, define system-level objectives and success criteria, assess hardware/software readiness, analyze flight data for anomalies and trends, produce deployment-readiness recommendations, and build automated test tooling to increase test capacity and precision. Collaborate cross-functionally and travel for flight testing.

Lead a multidisciplinary test engineering team to design, build, and execute test campaigns for safety-critical drone hardware (Platform 2), develop test equipment, root-cause failures with design teams, and grow hiring and team capabilities to enable high-volume, reliable deployments.

As a Motor Firmware Engineer, you'll develop high-performance firmware for motor controllers, collaborating with multi-disciplinary teams, validating firmware, and improving flight software reliability.

Design and implement high-performance motor controllers and estimators in C++ for bare-metal ARM microcontrollers, write peripheral drivers, validate firmware on bench and flight tests, develop simulations and HIL tests in Rust/Python/Matlab/Julia, and collaborate across hardware, flight software, and operations to improve reliability and fleet monitoring.
