Test Technician - Photonics
Make our optical benches sing. Join a hands-on photonics team building the laser sources that power next-gen AI and cloud infrastructure. An ideal entry point into the fastest moving industry of today
About Solinide Photonics
Solinide Photonics develops next-generation optical components and modules for high-speed data communication and co-packaged optical (CPO) systems. Our roadmap centres on external laser sources packaged in the OIF ELSFP form factor - the building blocks that supply optical power to the AI and cloud infrastructure of the next decade. We are a small, hands-on engineering team based in Gothenburg/Partille, and we are scaling the lab as we move from prototype to qualification.
About the Role
As a Test Technician you set up fixtures, align fibre, run characterisation and reliability tests on photonic components and ELSFP modules, and keep our measurement equipment in top condition. You will work side-by-side with design engineers, capture data that directly feeds product decisions, and over time take more ownership of test stations and procedures.
This is an excellent entry point into the photonics industry for someone who is meticulous, curious, and enjoys working with their hands on advanced equipment.
What You Will Do
Optical bench setup and alignment: build and align free-space and fibre-coupled test setups using lasers, fibre, lenses, isolators, optical power meters, OSAs, and spectrum analysers.
Component and module testing: perform characterisation, qualification, and production-style tests on lasers, photodiodes, sub-assemblies, and ELSFP modules following written procedures.
Equipment maintenance and calibration: carry out routine calibration, preventive maintenance, troubleshooting, and minor repair of optical and electrical test equipment; manage spares and consumables.
Prototype assembly: assemble box-based prototypes, including fibre cleaning and connection, soldering, and making cable assemblies.
Data capture and reporting: collect, organise, and graph measurement data; write clear test reports; flag anomalies to design engineers.
Test station bring-up: help engineers prototype and validate new test fixtures, document procedures, and transfer them to routine use.
Lab housekeeping and safety: keep the laser lab clean, ESD-controlled, and compliant with laser safety requirements (Class 3B/4).
(Optional) Test automation: modify or extend Python or LabVIEW scripts that drive instruments and log data — training will be provided if this is new to you.
What We Are Looking For
Required
Upper-secondary technical education (gymnasium teknik/el) or YH/KY degree in photonics, electronics, mechatronics, physics, or a related field.
Hands-on lab experience (internships, thesis work, and hobby projects all count).
Comfort working with fibre-optic components and basic optical instruments.
Meticulous, methodical, and patient — you enjoy getting things right and writing down what you did.
Good written and spoken English.
Eligible to work in Sweden.
Nice to Have
Familiarity with laser safety (Class 3B/4) and ESD-controlled environments.
Basic Python or LabVIEW scripting for instrument control and data logging.
Experience with fibre handling, cleaving, splicing, or connectorisation.
Experience with electrical assembly (soldering, connectors, etc.).
Exposure to telecom or datacom optical components (transceivers, ROSAs/TOSAs, lasers).
Working knowledge of Swedish.
Application
Applications are reviewed continuously, so apply early. Tell us about the most interesting lab/experimental setup you have built — at school, on an internship, or as a hobby.
About Solinide Photonics AB
Solinide Photonics is a silicon nitride (SiN) photonics foundry and product company, born out of world-leading research at Chalmers University of Technology. We design our chips, run our cleanroom process, and own the full path from physics to product, from dispersion-engineered waveguides to finished microcomb devices.
We're a small, dedicated team, which means everyone here shapes the direction of the company and sees their work reach real impact. We're building partnerships with the companies defining next-generation networks and bringing a genuinely new optical technology to market. If you want to work at the edge of photonics, where fundamental physics meets one of the fastest-growing markets in tech, this is where that happens..
