About Doodle Labs
Doodle Labs builds the connectivity backbone of the autonomous systems revolution - resilient wireless mesh networks that let drones, robots, and unmanned platforms operate reliably in the world's most demanding environments. We sit at the intersection of defense, robotics, and next-generation autonomy, powering the machines that are changing how militaries, first responders, and industries operate in the field. Our core purpose is simple: connect anyone and anything, at any time, in any place.
For over 25 years, our team has been at the forefront of mesh networking, partnering with leading defense programs, robotics manufacturers, and system integrators worldwide. The work here doesn't sit in a slide deck - it ends up in the field, in the hands of people for whom failure isn't an option.
About the Role
The Senior RF Hardware Engineer is responsible for hands-on RF circuit design for variants of Doodle Labs' radio platforms and will play a key role in building our new US-based RF hardware design team in Austin, TX.
In this role, you will work closely with the RF Design Manager, our Singapore R&D team, and product engineering to design, simulate, and validate higher-power and new form-factor radio modules. This role will help shape the next generation of Doodle Labs radio hardware as Doodle Labs continues to scale.
This is an opportunity to own RF designs end to end, from schematic to production, within a high-growth company at the forefront of wireless networking and autonomous systems.
What You’ll Do
- Own and drive hands-on RF circuit design for platform variants, including higher-power versions and new form factors
- Design RF front ends and power amplifiers up to 20 W linear at the component level, below 7 GHz
- Simulate and design supporting circuitry, including DC power conditioning, AC/DC and DC/DC converters, digital interfaces, I/O, USB, and Ethernet
- Lead RF simulation and validation testing before and after hardware fabrication
- Develop compact, scalable designs that support multiple frequency bands and product configurations
- Direct the RF Characterization Engineer on builds, parts selection, and testing
- Collaborate cross-functionally with our Singapore R&D, PCB layout, mechanical, and product engineering teams
- Produce schematics, design rationale, and test documentation and contribute to design reviews
What Success Looks Like
- Measurable impact on delivery of validated radio module variants ready for production
- Flexible designs that support multiple SKUs with minimal redesign
- Smooth production transfers with clear handoffs to manufacturing
- Strong cross-functional collaboration and alignment
- Clear, thorough technical documentation that the wider team can build on
Who You Are
- 8+ years of experience in board-level RF hardware design for wireless systems
- Expert-level RF circuit design at the component/transistor level, beyond block-level integration or PCB layout alone
- Hands-on design experience below 7 GHz, including power amplifier design up to 20 W linear
- Strong understanding of supporting circuitry (power conditioning, DC/DC and AC/DC converters, digital logic, I/O, USB, Ethernet) and how to simulate it
- Experience with RF simulation, performance validation, and high-frequency PCB layout
- Track record taking RF products from prototype to production
- Bachelor's or master's degree in Electrical Engineering, RF Engineering, or a related field
- Ability to work cross-functionally with both technical and non-technical teams
- Excellent communication, problem-solving, and organizational skills
- Experience operating in fast-paced or high-growth environments
Preferred Qualifications
- Experience in drones, robotics, autonomy, wireless networking, or defense markets
- RF circuit design experience at a Wi-Fi or long-range wireless hardware company
- Background in high-power RF design, such as land mobile radio or similar communications products
- Experience working with OEMs, embedded systems, or hardware products
- Familiarity with RF simulation tools (e.g., Keysight ADS, AWR Microwave Office) and RF test equipment
- Exposure to Wi-Fi, BLE, GPS, or high-power amplification design
- Advanced degree or specialized certifications
Why Join Doodle Labs
- Work on cutting-edge technology powering the future of autonomous system
- Collaborate with engineers and innovators building industry-leading connectivity solution
- Make a meaningful impact in a fast-growing company shaping the next generation of robotics and wireless networking
- Direct ownership of product performance in hardware tested in real-world deployments
