Overview
Direct message the job poster from Stella Doradus Europe Ltd
CTO at Stella Doradus | Driving Tech Innovation
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.
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.
Role and Responsibilities
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.
Qualifications and 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, ADCs, 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.
* Familiar with Source Code Version Control tools (Git).
* Familiar with Bug/Issue Tracking tools.
* Ability to communicate clearly and effectively, keeping team members and management informed of progress and issues.
* The candidate must have a Bachelor or Master’s degree (PhD preferred) in Telecommunications, Computer Science, Software or equivalent engineering degree.
* Experience with RF hardware such as amplifier chains, power detectors, mixers. Board design using Cadence is a must.
* 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; using these to control RF circuits is useful.
* Experience with RF lab equipment (spectrum analyzers, VNAs, signal generators).
* Some experience with Python or other scripting languages is desirable.
* Notice: The applicant must be eligible to work and live in Ireland.
