About the Team

DoorDash Labs is an independent innovation hub within DoorDash, focusing on developing automation and robotics solutions to enhance last-mile logistics. Our mission is to create technologies that support and augment human networks, aiming to improve efficiency for Dashers, merchants, and consumers alike. We are a highly senior team composed of former pioneers from a variety of different robotics industries. If you have a passion for applying AI and robotics solutions in a service used by millions of people, then we want to talk to you!

Please Note: This role is based in San Francisco, CA, and requires being in-person 5 days a week.

About the Role

We are seeking a Senior RF Engineer to join our multidisciplinary team developing mission-critical RF/electrical systems for unmanned platforms.This role offers a rare opportunity to gain deep insight into RF design and validation, contributing across the full product lifecycle, from early concept and prototyping through production. In this role, you will apply deep expertise in electromagnetic theory and wireless system design to ensure autonomous platforms operate with exceptional reliability and precision. You will design, optimize and validate RF / mixed-signal PCBAs with a strong focus on interference mitigation, troubleshoot system-level desense, and leverage a thorough understanding of wireless technologies including LTE, 5G NR, Wi‑Fi, GPS, and UWB.

You’re excited about this opportunity because you will…

• Lead the development of innovative solutions that span across RF, Mixed signal and mechanical domain.
• Design RF hardware as well as wireless testbeds to support system validation, and lead the execution and documentation of system-level design and verification
• Provide expertise, mentorship to partner teams regarding EMI mitigation strategies, and cross-functional debug processes
• Characterize EMI caused by internal & external aggressors by tracing root causes using EMC probes, shielding tests, grounding checks, and layout reviews
• Conduct rigorous lab and OTA testing of RF systems, including sensitivity and coexistence evaluations across LTE, 5G NR, Wi‑Fi, GNSS, and validate performance against industry standards
• Perform EM simulations using cad tools (CST, HFSS, ADS) to develop deep understanding of product behavior and drive informed design decisions
• Clearly communicate technical challenges, gaps and trade-offs to fellow engineers and executives

We’re excited about you because you have…

• 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 in 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 working with systems that include high‑speed digital interfaces such as MIPI CSI / DSI, PCIe, DDR, SDIO / eMMC
• Proficient in the use of RF test and measurement equipment, including oscilloscopes, spectrum analyzers, and network analyzers
• Hands‑on expertise in desense mitigation techniques, including shielding, grounding, and filtering, leveraging both simulation and empirical measurement data to drive root cause analysis
• Excellent data analysis, report writing, presentation skills, and desire to work in fast paced environment
