Careers
We are recruiting key early hires across photonics and machine learning, who will join us in pioneering our next-gen photonic hardware. These roles are primarily in person in West London. Rayd Technologies works closely with research groups at Imperial College, EPFL and Paul Scherrer Institute in Switzerland.
This is a truly unique opportunity to join a dynamic company with a ground-breaking technology at a very early stage, and to be part of our vision to improve processing performance by many orders of magnitude. With us you will find a stimulating environment which values initiative and risk taking and is open to diversity in all its forms. We expect to grow in the coming years thus providing great opportunities for career development and personal growth.
We are looking for talented and motivated applicants. We go beyond the conventional platforms hence you should be willing to apply your knowledge, but also grow and expand your expertise as we develop the hardware. We look for applicants at all levels of expertise, from the fresh out of university to the established professional.
Open roles:
Machine Learning Engineer
Photonic Engineer (Photonic Device Design & Testing)
Photonic Engineer (Optical Setup & Automation)

Lead the development and refinement of novel machine learning architectures and algorithms harnessing our nonlinear dynamics. Building deeper network architectures that maximise efficiency and performance.
Design, build and test models both on device and using in-house simulation framework.
Collaborate closely with the wider photonics and hardware team to design and evaluate general metrics to assess the computational properties of the hardware and optimise for computational performance.
Research state-of-the-art machine learning & machine vision techniques and adapt them to be compatible with our hardware.
Communicate results with the broader team both at Rayd Technologies and at Imperial / EPFL.
Your skills and experience:
Strong proven background in ML algorithm development, particularly for visual and high-dimensional data processing.
Expert-level proficiency in Python and common ML frameworks (e.g. PyTorch, Jax, Tensorflow)
Demonstrable experience in performance benchmarking and model optimisation.
Deep background in fundamentals of machine learning.
Strong team player, excellent communication and teamwork skills, with an ability to articulate complex concepts clearly.
>3 years experience in Machine Learning, Computer Vision, or a related quantitative field.
Deep knowledge of state-of-the-art machine vision algorithms and methods.
Compensation:
Competitive salary depending on experience.
25 days paid annual leave + bank holidays.
Competitive stock options package.
Enrolment to employee pension scheme.
Annual budget for development including conferences, tradeshows and courses.
As the company grows, you will have opportunities to take on greater responsibilities.

Manage the full data lifecycle: collection, in-depth analysis, and clear presentation of results and conclusions.
Collaborate with the machine learning team to co-design and optimise networks for specific computational properties.
Use Ansys products (or similar) to simulate optical experiments and validate designs.
Perform numerical simulations (e.g., in Python) to model chip behaviour and compare it with experimental results.
Qualifications & Skills:
Proven, hands-on experience in data collection, analysis, and presentation of experimental results.
Background in nonlinear photonics / lasers / ultrafast optical spectroscopy.
Practical experience in a optics lab environment.
Proficiency in Python for data analysis and numerical simulation.
Experience with photonic experimental design tools.
Excellent teamwork and communication skills.
Compensation & Benefits:
Competitive salary depending on experience
25 days paid annual leave + bank holidays
Competitive stock options package.
