Signal Integrity Engineer – Photonic Networking

Epic Centre; Paignton; On-site; GBP 70,000 - 105,000; Full time

Job summary

Oriole Networks in Paignton is seeking a PhD-level RF/High-Speed Electronics Engineer to design and characterise high-frequency interconnects and transceiver electronics. You will work at the intersection of RF, SI, and electro-optics with photonic components operating at multi-tens of GHz and beyond.

You will develop full-wave EM models, perform calibrated RF measurements, and co-design electronic interfaces for integrated photonic switches, collaborating with photonics and systems teams to

Qualifications

• 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 in multidisciplinary teams.

Responsibilities

• High-speed circuit design: Interconnects and transceiver electronics including drivers, TIAs, and front-end circuits for modulators and photodetectors.
• 3D EM modelling & simulation: Full-wave models of RF structures, interconnects, and packaging; correlating with measurements.
• Measurement & characterisation: Calibrated RF measurements using >50 GHz instrumentation.
• Electro-optic integration: Co-design electronic interfaces for integrated photonic switches and transceivers with photonics teams.
• Prototype bring-up & debugging: Schematic/PCB reviews, lab debugging, performance optimisation.
• Data analysis & automation: Use Python or MATLAB for data analysis, modelling, and lab automation.
• Documentation & communication: Report results and insights across multidisciplinary teams.
