Oriole Networks is building next-generation photonic networking systems to power the future of AI and high-performance computing. By moving data with light instead of electrons, we enable dramatically higher bandwidth, lower latency, and reduced energy consumption.
We are taking optical circuit switching from cutting-edge research to real-world deployment, enabling the next generation of scalable AI infrastructure. Backed by strong funding and deep academic roots, we are building a world-class team to turn breakthrough science into production systems.
The Role:
We are seeking a PhD-level RF / High-Speed Electronics Engineer with a strong foundation in applied mathematics, electromagnetic theory, and measurement science.
You will work at the intersection of RF engineering, signal integrity, and electro-optics, developing high-frequency systems that interface closely with advanced photonic components operating at multi-tens of GHz and beyond.
This role is ideal for candidates who think from first principles, are rigorous in experimentation, and are motivated to bridge theory, simulation, and real-world measurements.
What You’ll Do:
* High-speed circuit design: Contribute to high-speed interconnects and transceiver electronics, including drivers, TIAs, and front-end circuits for modulators and photodetectors
* 3D EM modelling & simulation: Develop and apply full-wave 3D electromagnetic models of RF structures, interconnects, and packaging (e.g. using HFSS, CST), alongside analytical models (transmission lines, S-parameters, noise, linearity, SI/PI), and correlate predictions with measured data
* Measurement & characterisation: Design and execute calibrated RF measurements (VNA SOLT/TRL, de-embedding, time- and frequency-domain analysis) using >50 GHz instrumentation
* Electro-optic integration: Co-design electronic interfaces for integrated photonic switches and transceivers, working closely with photonics and systems teams
* Prototype bring-up & debugging: Support schematic and PCB reviews, lab debugging, and performance optimisation
* Data analysis & automation: Use Python or MATLAB for data analysis, modelling, and lab automation
* Documentation & communication: Clearly document results and communicate insights across multidisciplinary teams
Required Qualifications and Experience:
* PhD in Electrical/Electronic Engineering, Physics, Photonics, or a closely related field.
* Deep understanding of electromagnetics, RF/microwave engineering, and high-frequency circuit theory.
* Experience with 3D electromagnetic simulation tools (e.g. HFSS, CST, or similar full-wave solvers)
* Strong applied mathematics background (linear algebra, signal processing, numerical methods, optimisation).
* Hands‑on experience with RF measurement techniques and instrumentation (VNAs, oscilloscopes, spectrum analysers, BERTs)
* Programming skills for modelling and data analysis (Python, MATLAB, or similar)
* Ability to apply theory to real systems and extract insight from experimental data; clear communication and effective collaboration in multidisciplinary teams.
* Signal integrity / power integrity for high-speed interconnects
* Silicon photonics, co‑packaged optics, or optical communications
* Strong experimental expertise (calibration, de‑embedding, fixture design, noise/linearity/BER measurement)
* PCB design and EDA tools (e.g. Cadence, PADS)
* Exposure to FPGA development (Verilog/VHDL)
* Thermal considerations in high-density electronic systems
* Publications in relevant journals or conferences
