RF Hardware Developer

Are you curious about RF design and wireless technology? At RTX, you can help develop advanced wireless products used by leading international brands — while working with skilled colleagues in an informal and collaborative environment.

Some of your key responsibilities will entail: 

• Collaborate with colleagues across Mechanics, Hardware, Acoustics, Software and Production to create strong product solutions.
• RF Circuit design including areas like link budget, antenna simulation & design, selection and evaluation of relevant transceivers, PAs, RF switches, RF filter etc.
• Integration of the design, with RF performance in mind, into the full product often with limited PCB size available.
• Support prototype builds, define RF test specifications and analyze production data.
• Verify RF performance against product and regulatory requirements in our in-house labs.
• Contribute to continuous improvements, cost savings, product maintenance and documentation of key learnings.

We expect you to have: 

• A B.Sc. or M.Sc. in Electronics Engineering, with solid knowledge of microwave RF and antenna design.
• Experience with RF system & antenna designs & simulations for small-size device
  • Experience in practical RF-lab work: E.g., using a network or spectrum analyzer, verifying specific radio performance parameters Rx/Tx performance, frequency synthesis, impedance matching techniques etc.
  • Understanding of product development for high-volume production, regulatory requirements such as DECT, WiFi or Bluetooth, and TDMA radios or similar RF technologies is an advantage.
  • Strong English communication skills and a collaborative mindset in an international environment.
  • A structured, responsible approach to your tasks, with focus on quality, deadlines and complex problem solving.

Your workplace will be our headquarters in Nørresundby, Denmark.

What we offer:

As an RF Hardware Developer at RTX, you will work on wireless products across Enterprise, ProAudio and Healthcare. You will be involved from early specifications and design to verification, type approval and handover to mass production.

You will help design radio solutions and antennas for products where size, performance and reliability matter — from headsets and handheld devices to enterprise access points.

We offer a role in an international company with a flat structure, flexible ways of working and a high level of trust. You will join a team of experienced specialists, work with advanced technologies and have room to learn, contribute and influence solutions.

Who we are:

At RTX, wireless is not just wireless! We make an effort to understand how the specific use cases can be optimized through wireless technology, as well as explore how the link between products configured in a system can make a difference and help the user perform at their best. 

We innovate, design, and manufacture wireless communication solutions within three segments: 

• Enterprise solutions covering amongst others, wireless communication systems connecting handsets and headsets via base stations. 

• Healthcare solutions where wireless systems are used for monitoring critically ill patients, among others. 

• ProAudio solutions, including communication modules used in e.g., advanced team intercom solutions, and live event and studio equipment, providing high audio quality 

We have the ambition to create ground-breaking technologies while also creating value for our customers and end-users. Working in close partnership with our customers, we offer customized, ‘turn-key’, end-to-end solutions with full product lifecycle management designed to meet the ambition of their portfolio and brand.
