Freelance Rf Design Engineer information

What is a freelance RF design engineer?

Freelance RF Design Engineers are independent professionals who specialize in designing, testing, and optimizing radio frequency (RF) circuits and systems for various applications, such as telecommunications, wireless networks, and broadcasting. Unlike salaried employees, they work on a contract or project basis for different clients, providing their expertise on-demand. Their responsibilities often include creating schematics, selecting components, running simulations, and ensuring compliance with industry standards. Freelance RF Design Engineers need strong technical skills, up-to-date knowledge of RF technologies, and the ability to manage projects independently.

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

To thrive as a Freelance RF Design Engineer, you need a strong background in electrical engineering, RF circuit theory, and experience with wireless communication systems, often supported by a relevant degree or certification. Proficiency with RF simulation and design tools like HFSS, ADS, or CST, as well as familiarity with PCB design software, is typically required. Strong problem-solving skills, attention to detail, and effective communication are crucial soft skills for successful project delivery and client interactions. These skills and qualifications are essential to design reliable RF systems, meet client specifications, and maintain competitiveness in a project-based environment.

What are some common challenges faced by freelance RF design engineers when working with multiple clients simultaneously?

Freelance RF Design Engineers often juggle projects for several clients at once, which can present challenges such as managing different project timelines, adapting to varied technical requirements, and ensuring clear communication across diverse teams. Balancing priorities and staying organized are crucial to delivering quality work within tight deadlines. Additionally, freelancers need to quickly familiarize themselves with each client's unique tools and processes, making adaptability and proactive problem-solving essential skills for success in this role.

What is the difference between Freelance Rf Design Engineer vs Rf Design Engineer?

AspectFreelance Rf Design EngineerRf Design Engineer

Job description

Overview

At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. Our team solves tough, meaningful problems that create a safer, more secure world.

Effector RF Design Department is responsible for designing RF and microwave hardware, including transmitters, receivers, and exciters. This includes design and test activities that span preliminary design to integration. Products we develop support radar and datalink applications on a variety of tactical missile programs. Critical to this role is designing for challenging mechanical constraints and extreme environments. The position is onsite, located in Tucson, AZ.

Clearance Requirements

U.S. citizenship is required. An active and transferable DoD Secret security clearance, or the ability to obtain an interim U.S. government issued security clearance prior to the start date, is required.

What You Will Do
  • Design and develop transmitters, receivers or exciters.
  • Design circuit card assemblies (CCAs) with RF or mixed signals.
  • Work in a lab to accomplish component characterization, module verification, and integration.
  • Test and handle sensitive RF hardware.
  • Capture schematics and perform RF routing.
  • Partner with interdisciplinary teams – power, digital, mechanical, etc.
Qualifications You Must Have
  • Typically requires a Bachelor’s degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of two years of relevant experience, including any combination of the following:
  • Experience with RF design and fabrication.
  • Experience with RF testing and troubleshooting.
  • Experience with simulation of RF products.
  • Experience with any of the following tools: Mentor DX Designer or equivalent; High Frequency Structure Simulator (HFSS) or equivalent; SystemVue/Genesys or equivalent; Advanced Design System (ADS) or equivalent.
  • Ability to obtain an interim U.S. government issued security clearance prior to the start date with the ability to obtain special program access thereafter.
We Prefer
  • Mentorship or apprenticeship experience.
  • Technical oversight responsibilities for less senior engineers.
  • Experience working across domains on complex projects.
  • Architecting and requirements definition for complex RF products.
  • Team leadership experience on technical projects, including cost and schedule (EVMS or CAM) experience.
  • Ability to prepare documentation with minimal oversight.
  • Background in designing for manufacturability, producibility, and cost constraints, including yield and margin analysis.
  • Technical background in cascade analysis and/or frequency planning, filter design and fabrication, circuit card assembly design and fabrication, testing or designing RF hybrid (chip and wire) technologies, and high‑speed data converter test/characterization.
  • High power RF design or test experience.
  • Scripting experience (Matlab or Python).
  • Some front‑line leadership experience desirable.

About Pratt & Whitney

Sourced by ZipRecruiter

Pratt & Whitney has a long history of leadership and innovation in the field of aviation propulsion. Our story begins in the 1920s and has flourished throughout the decades. We have continuously transformed and reinvented our businesses to offer superior products and services to our customers. In 1925, the Pratt & Whitney Aircraft Company was founded by Frederick B. Rentschler, pioneer of the air-cooled radial engine design which enabled unprecedented power-to-weight ratio. Its first engine, the R-1340 Wasp engine, transformed military and commercial aviation and is still in use today. In 1928, the Canadian division of the Pratt & Whitney Aircraft Company was established. In 1944, Pratt & Whitney began its gas turbine and jet propulsion initiative. The company constructed a wind tunnel, laboratory and engineering center to support our allies’ efforts in World War II. In 1945, wartime production included more than 300,000 Pratt & Whitney engines, touted by service members as extremely dependable – a legacy that continues today. From there, Pratt & Whitney continued to design and innovate more powerful, agile, and reliable engines becoming a leader in the aerospace industry. Today, Pratt & Whitney has more than 85,000 engines in service and more than 16,000 customers worldwide.
