Original job description

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

Compensation & Benefits Doodle Labs offers competitive compensation and a comprehensive benefits package built for people doing serious work.

Compensation: Competitive base salary, individual and company performance bonuses.
Health & Wellness: Medical, dental, and vision coverage. Plus One Medical, Teladoc, Talkspace, Health Advocate, Kindbody, and sponsored gym memberships
Retirement: 401(k) with company contributions (US)
Professional Development: Access to courses, certifications, and conferences
Commuter Benefits: Pre-tax commuter savings for transit and parking (US roles)
Time Off: Paid time off, Federal and Bank holiday's observed, plus a company-wide holiday shutdown from Christmas through New Year's
Relocation Assistance: Available depending on role eligibility

Travel Expectations This role may require up to 10% travel for collaboration with our Singapore R&D team, field testing, or industry events.
