DoorDash Labs is an independent innovation hub within DoorDash focused on developing automation and robotics solutions for last-mile logistics. The team comprises highly senior engineers from diverse robotics backgrounds, applying AI and robotics to improve efficiency for Dashers, merchants, and consumers.
You will join a multidisciplinary team developing mission-critical RF and electrical systems for unmanned autonomous platforms. This role offers deep involvement across the full product lifecycle, from early concept and prototyping through production.
Key responsibilities include:
- Lead development of innovative solutions spanning RF, mixed-signal, and mechanical domains
- Design RF hardware and wireless testbeds to support system validation
- Execute and document system-level design and verification
- Provide expertise and mentorship to partner teams on EMI mitigation strategies and cross-functional debugging
- Characterize EMI from internal and external sources using EMC probes, shielding tests, grounding checks, and layout reviews
- Conduct rigorous lab and over-the-air (OTA) testing of RF systems, including sensitivity and coexistence evaluations across LTE, 5G NR, Wi-Fi, GNSS
- Validate performance against industry standards
- Perform electromagnetic simulations using CAD tools (CST, HFSS, ADS) to understand product behavior and drive design decisions
- Communicate technical challenges, gaps, and trade-offs clearly to engineers and executives
The role requires in-person presence 5 days per week in San Francisco.
Requirements:
- Bachelor's or Master's degree in Electrical Engineering with specialization in RF engineering, applied electromagnetics, or wireless systems
- 6+ years of hands-on experience designing and testing RF hardware for consumer-grade mass-produced products
- Strong RF fundamentals with expertise in front-end design, desense analysis, and system-level optimization
- Experience with systems including high-speed digital interfaces (MIPI CSI/DSI, PCIe, DDR, SDIO/eMMC)
- Proficiency with RF test and measurement equipment (oscilloscopes, spectrum analyzers, network analyzers)
- Hands-on expertise in desense mitigation techniques (shielding, grounding, filtering) using both simulation and empirical measurement
- Excellent data analysis, report writing, and presentation skills
- Ability to work in a fast-paced environment
