Wireless Systems Engineer (IoT Infrastructure)

Job DescriptionJob DescriptionDescription:About the Role

We are seeking a skilled and versatile Wireless Systems Engineer with a blend of software and wireless engineering skills to join our team. This role sits at the intersection of embedded systems development, wireless systems, and RF validation — ideal for someone who thrives in a hybrid environment spanning hardware, firmware, and systems integration.

You will work as part of the engineering team helping to design, implement, and test new features in IoT infrastructure devices. In this role you will develop embedded software, integrate wireless systems, build test tools, and debug complex issues spanning wireless communications, RF interference, and embedded software behavior.

Responsibilities

• Design and implement embedded applications in C, C++, and Python for IoT devices focusing on testability, maintainability, and performance
• Review code contributions and participate in firmware and hardware design reviews
• Write and maintain clear, structured technical documentation
• Collaborate with hardware and firmware engineering teams to debug and resolve integration issues spanning RF, software, and systems layers
• Analyze and interpret measurement data to validate device performance and ensure compliance with functional and performance requirements
• Design, document, and execute RF and wireless validation test plans for IoT devices
• Build tools and scripts for system validation and test automation

Required Qualifications

• 5–10 years experience in wireless embedded systems development
• Solid understanding of RF fundamentals, link budgets, propagation, interference, and wireless system design constraints
• Strong programming skills in C, C++ for embedded applications
• Experience with embedded Linux, including toolchain use and user-space development
• Familiarity with Linux networking and firewall rule definition
• Comfortable with Linux command-line workflows and Bash scripting

Qualifications

• Familiarity with RF regulatory compliance (e.g., FCC, IC, NOM)
• Experience integrating and validating IoT protocols such as BLE, LoRa, Zigbee
• Familiarity with RF performance characterization: BER, PER, sensitivity, ACPR, EVM, intermodulation, noise figure, and interference rejection
• Exposure to Yocto Linux or buildroot build systems
• Familiarity with CI/CD workflows and pipelines such as GitHub Actions
• Hands-on experience using RF lab test equipment: spectrum analyzers, signal generators, oscilloscopes, power meters, noise figure meters
• Background in software-defined radio (SDR) simulation and development

Work Environment

• This role is primarily on-site at our Atlanta office and lab facility
• You'll work in close collaboration with multi-disciplinary engineering teams (hardware, firmware, systems, and QA)

What We Offer

• A small, agile, and experienced team that values ownership, quick iteration, and making big impacts
• Opportunities to influence product design and technical approaches
• A collaborative engineering culture that values technical depth, curiosity, and systems thinking
