TrellisWare launched in 2000 with an innovative culture striving to push technological boundaries in the area of wireless communications. We are now a worldwide leader in highly advanced algorithms, waveforms, and communications systems that range from small form factor radio products to fully integrated solutions.

At TrellisWare, we connect passion with purpose and together we make an impact- on our careers, our company, and the world. And you can too. If you love to innovate and collaborate in a dynamic environment where boundaries are being pushed, you belong at TrellisWare. Where the opportunity to serve is not a challenge but a gift. Where you’re never going alone. Because there’s too much at stake to go solo.

Our Hardware Team is seeking an RF Design Engineer.

You would be responsible for designing and developing highly selective receive chains and 2-20 watt transmit chains for VHF, UHF, L, and S-band handheld and vehicular radios. TrellisWare’s products are engineered to provide robust and reliable communication in congested and contested RF environments. TrellisWare is looking for RF engineers who can combine the latest integrated components alongside custom-designed discrete filters and amplifiers, balancing transmit power, battery life, spurs and harmonics, receive selectivity, noise figure, and overall size to produce cutting-edge radios.

The essential duties and responsibilities include

System-level RF design, including component selection and cascade analysis, using AWR Microwave Office

Component level design, leveraging integrated solutions but primarily focused on custom discrete filters and amplifiers

RF schematic entry (and ideally PCB layout) using Altium toolchain

Generate required design documentation.

Validate and debug product performance through test and analysis at the component, module and system level.

Collaborate with Product Management and Operations to carry development from prototype to production.

Perform other duties as assigned.

Education and work experience requirements are

Minimum Bachelor’s degree in electrical engineering or related field of study required.

5 years of experience with MSEE or 7 years of experience with BSEE as a RF/Wireless Design Engineer.

To be considered for this position, you would need to meet, at a minimum, the knowledge, skills, and abilities listed here:

RF cascade analysis and optimization for both noise figure and performance in strong interference environments

Filter synthesis and design, especially for low-loss, high power filters using lumped elements

Schematic entry and PCB layout experience (ideally using Altium tools)

Linear RF simulation (ideally using AWR Microwave Office)

Hands-on experience with RF circuit bring-up, troubleshooting, optimization, and high-volume production

Additional requirements are

U.S. Citizenship or Permanent Residency

An exceptional candidate would also possess the following knowledge, skills, and abilities:

Discrete amplifier design experience, particularly at 1 W and above

Understanding of both the features and limitations of integrated RF transceivers

Experience with non-linear simulations, including simulated load-pull analysis

Understanding of frequency conversion, frequency synthesizers, and PLL design up to 3 GHz with tight packaging constraints.

Experience with EM Solvers such as HFSS, Momentum, Analyst or AXIEM (preferred).

Work independently, demonstrate initiative and interact with a variety of engineering development teams.

Demonstrate strong documentation skills and proficiency with PC office applications.

Demonstrate analytical and problem-solving skills.

Demonstrate strong written and verbal communication skills.

Strong collaborative drive and interpersonal skills.

Strong initiative, proactive work ethic and prioritization skills.

Sound judgement and analytical problem-solving skills.

Effective execution and decision making.

Champion of change and promotes innovation.

Strong written and verbal communication skills.
