Radio Frequency Hardware Engineer - DoorDash Air
About The Position
DoorDash Labs is an independent innovation hub within DoorDash that develops automation and robotics solutions to enhance last-mile logistics. The team is seeking a Senior RF Engineer to develop mission-critical RF and electrical systems for unmanned platforms. The role covers the product lifecycle from early concepts and prototyping through production, applying electromagnetic theory and wireless-system design to help autonomous platforms operate reliably and precisely. The engineer will design, optimize, and validate RF and mixed-signal PCBAs, with a focus on interference mitigation and system-level desense troubleshooting. The role works across RF, mixed-signal, and mechanical disciplines and involves wireless testbed development, system validation, lab and over-the-air testing, electromagnetic simulation, and communication of technical trade-offs. This position is based in San Francisco, California, and requires in-person work five days per week.
Requirements
- Bachelor’s or Master’s degree in Electrical Engineering, specializing in RF engineering, applied electromagnetics, or wireless systems.
- At least 6 years of hands-on experience designing and testing RF hardware for consumer-grade mass-produced products.
- Strong RF fundamentals, including expertise in front-end design, desense analysis, and system-level optimization.
- Experience with systems that include high-speed digital interfaces such as MIPI CSI/DSI, PCIe, DDR, and SDIO/eMMC.
- Proficiency with RF test and measurement equipment, including oscilloscopes, spectrum analyzers, and network analyzers.
- Hands-on expertise in desense mitigation techniques, including shielding, grounding, and filtering, using simulation and empirical measurements for root-cause analysis.
- Excellent data analysis, report-writing, and presentation skills, and a desire to work in a fast-paced environment.
Responsibilities
- Lead development of solutions spanning RF, mixed-signal, and mechanical domains.
- Design RF hardware and wireless testbeds for system validation, and lead execution and documentation of system-level design and verification.
- Provide expertise and mentorship to partner teams on EMI mitigation strategies and cross-functional debug processes.
- Characterize EMI from internal and external aggressors and trace root causes using EMC probes, shielding tests, grounding checks, and layout reviews.
- Conduct lab and over-the-air testing of RF systems, including sensitivity and coexistence evaluations across LTE, 5G NR, Wi-Fi, and GNSS, and validate performance against industry standards.
- Perform electromagnetic simulations using CST, HFSS, and ADS to understand product behavior and inform design decisions.
- Communicate technical challenges, gaps, and trade-offs to engineers and executives.
