What does a senior RF engineer do?

A senior RF engineer designs, develops, and tests radio frequency systems and components used in wireless communication devices. They analyze signal performance, troubleshoot issues, and often use simulation tools like MATLAB or HFSS. Their role requires strong knowledge of RF principles, circuit design, and industry standards, often supported by relevant certifications and experience in a fast-paced engineering environment.

What is a senior RF engineer?

Senior RF Engineers are experienced professionals who design, implement, and optimize radio frequency (RF) systems used in telecommunications, broadcasting, and other wireless communications. They are responsible for ensuring the performance and reliability of RF networks by conducting tests, troubleshooting issues, and developing solutions to improve signal quality. Senior RF Engineers often lead project teams, mentor junior engineers, and work closely with other departments to deliver effective wireless communication solutions.

What are some common technical challenges faced by senior RF engineers, and how are they typically addressed within engineering teams?

Senior RF Engineers often encounter challenges related to signal interference, system integration, and maintaining optimal performance under real-world conditions. These issues are typically addressed through collaborative troubleshooting with cross-functional teams, such as hardware, software, and test engineers. Utilizing advanced simulation tools, performing thorough field testing, and conducting design reviews are standard practices to ensure solutions are effective and reliable. Regular knowledge sharing within the team helps in quickly resolving complex RF problems and staying updated with evolving technologies.

Is RF engineering in demand?

RF engineering is in high demand due to the growth of wireless communication, 5G networks, and satellite technology. Senior RF engineers with expertise in signal processing, antenna design, and RF testing are sought after across telecommunications, aerospace, and defense industries.

What is the difference between Senior Rf Engineer vs RF Engineer?

AspectSenior RF EngineerRF Engineer
CredentialsBachelor's or Master's in Electrical Engineering, certifications like FCC or RF-specific coursesBachelor's in Electrical Engineering or related field, some certifications beneficial
Work EnvironmentDesign, testing, and troubleshooting RF systems in labs or fieldAssist in RF system development, testing, and maintenance
ResponsibilitiesLead projects, optimize RF performance, mentor junior staffSupport RF design, perform measurements, and document results

The main difference lies in experience and responsibility level. Senior RF Engineers typically lead projects and mentor others, while RF Engineers focus on supporting design and testing tasks. Both roles require similar technical skills and certifications, but the senior position involves more leadership and strategic planning.

What are the key skills and qualifications needed to thrive as a senior RF engineer?

To thrive as a Senior RF Engineer, you need advanced knowledge of radio frequency theory, wireless communication systems, and a relevant engineering degree, often complemented by several years of industry experience. Familiarity with RF simulation tools (such as CST, HFSS, or ADS), network analyzers, and certifications like Certified Wireless Network Professional (CWNP) are typically required. Excellent problem-solving, analytical thinking, and effective communication skills help in troubleshooting and collaborating with cross-functional teams. These skills and qualities are vital for designing reliable RF solutions, optimizing performance, and ensuring seamless integration in complex wireless environments.

Re-posted 7 days ago

Job description

Underwater communication is one of the hardest wireless problems on Earth. Radio waves attenuate quickly underwater, so our systems use sound, much like whales and dolphins, to transmit high‑bandwidth data, including video. We are looking for engineers excited by challenging embedded DSP problems where algorithms, firmware, electronics, mechanics, and real‑world operating conditions all have to work together.

This is a high‑ownership role on a small, quickly growing team. You will not be one engineer among hundreds working on a narrow subsystem; you will have direct visibility into the full product, from modem firmware and acoustic signal processing to undersea drones and customer deployments.

About Us

Underwater, the wireless transfer of a single picture used to take an hour. OceanComm brought to market wireless modems that transfer data 100 to 1,000 times faster. Legacy modems were largely status and command links; our modems can control undersea drones with live video feedback, fundamentally changing what operators can see, decide, and do underwater. Leading organizations in defense, offshore energy and oceanographic research rely on OceanComm to keep their undersea systems connected.

What You Will Do
  • Develop and maintain real‑time embedded C/C++ code for core components of OceanComm’s acoustic modem firmware, owning features from concept through deployment
  • Provide technical leadership through exemplary code and design judgment that others trust and want to build on
  • Implement, optimize, and validate advanced acoustic signal processing algorithms
  • Collaborate with electrical, mechanical, systems, and field teams to define interfaces and verify system performance
  • Develop tests, tools, and procedures for firmware validation, hardware bring‑up, production test, troubleshooting, and repair
  • Help evaluate tradeoffs in performance, reliability, complexity, schedule, cost, and risk
  • Help improve engineering culture, communication, and technical standards as the team grows
Qualifications
  • B.S. or M.S. in Electrical Engineering, Computer Engineering or related discipline
  • 5+ years of experience developing embedded real‑time systems with C/C++
  • Proficiency in developing DSP software for real‑time systems
  • Solid knowledge of linear algebra, signal processing theory, algorithms, and implementation techniques (filters, transforms, synchronization, estimation, etc.)
  • Experience drafting technical documentation
  • Strong written and verbal communication skills
  • U.S. Person
What Will Put You Ahead
  • Experience with underwater acoustic communications, sonar, modem design, SDR, RF communications, or similar signal‑processing systems
  • Experience optimizing DSP algorithms for embedded platforms, including fixed‑point, floating‑point, memory, latency, or power constraints
  • Experience with machine learning models deployed on embedded platforms
  • Experience designing domain‑specific deep neural networks
  • Experience with analog and mixed‑signal integrated circuits, e.g., low‑noise amplifiers, analog‑to‑digital converters, and integrated analog‑front‑ends
Benefits
  • Competitive base salary and incentive stock options
  • Paid vacation starting at 20 days per year, increasing with tenure
  • Paid sick leave with carryover
  • Flexible schedule with core hours
  • Close mentorship from experienced engineers and technical leaders
  • Professional development support for conferences, books, courses, or technical training
  • Hands‑on work with advanced acoustic, embedded, and undersea robotics hardware
Compensation

The pay range for this position is $140,000 – $175,000 per year. Actual pay will depend on the candidate’s experience and skills demonstrated during interviews and other evaluations.

OceanComm is an Equal Opportunity Employer, including disability/vet.
