At Stella Doradus we are a dynamic, creative team developing and building cutting-edge mobile signal repeater products to solve mobile signal problems for our global customers.
We are looking for a senior RF engineer to work either in our Sandyford, Dublin office or our Waterford office.
Senior RF Engineer – Role Description
Stella Doradus designs and manufactures its complete range of mobile signal repeaters in Ireland. All manufacturing is carried out in-house using a state-of-the-art chip placement line. Each circuit is programmed and tested internally using automated LabVIEW systems, supported by Rohde & Schwarz signal generators, signal analysers, and network analysers.
As part of our RF design team, you will ensure that all RF designs achieve outstanding performance while maintaining strong manufacturability. A key responsibility will be to design products that integrate efficiently into our existing production processes. The re-use of components already approved and available on our manufacturing line will be an important aspect of your design approach.
Skills:
* At least 10 years experience designing and developing RF circuits and systems for wireless communication, including antennas, filters, amplifiers, mixers and transceivers.
* Knowledge of circuits such as Phase Locked Loops, Tx and Rx Equalizers, ADC's etc. Familiar with concepts of Jitter, Noise, and other non-idealities in circuits
* Excellent problem-solving skills
* Experience with GSM/4G/5G cellular technologies.
* Self driven - ability to work on own initiative.
* Solid understanding of wireless communication systems fundamentals
* Self-motivated and proactive to maintain momentum and progress
* Strong knowledge of developing and executing test plans to verify and validate a system's performance
* Must be familiar with Source Code Version Control tools (GIT)
* Must be familiar with Bug/Issue Tracking tools.
* Must be able to communicate clearly and effectively, keeping team members and management informed of progress and issues
Preferred Qualifications and Skills:
* The candidate must have a
Bachelor or Master's degree
(PhD preferred) in Telecommunications, Computer Science, Software or equivalent engineering degree.
* Must have experience and a history of working with and developing RF hardware such as amplifier chains, power detectors, mixers. Board design using software tools a must, particularly experience using Cadence.
* Strong understanding of RF principles, modulation techniques, and wireless standards (e.g., LTE, 5G).
* Understanding of RF concepts such as AGC, noise figure, power amplifiers, phase noise, PLL, oscillators/mixers.
* Experience using and programming Microchip PICS useful. Experience using these to control the RF circuits useful.
* Experience with RF lab equipment (e.g., spectrum analyzers, VNAs, signal generators).
* Some experience with Python or other scripting languages is desirable.
* Excellent English language skills.
* Notice: The applicant must be eligible to work and live in Ireland
