Benefits
At Lumiphase, you'll be part of a fast-growing and dynamic work environment where you can really make an impact. Our team is filled with top-notch technical experts who are always eager to share their knowledge and learn together. We have a diverse group of people from all over the world, making for a truly inclusive and open-minded team.
We offer a variety of benefits to create a positive experience at work and enable a healthy and enjoyable work-life balance:

• ZVV (Zurich region) annual transport pass and Halbtax
• 2 extra weeks of parental leave
• Free yoga classes on-site
• Flexible hours and the option to work remotely, plus our office is located in the beautiful greater Zurich area (Stafa, ZH - with a stunning view of the lake and summer swimming!)
• On-site fitness room, canteen, and a top-quality espresso machine
• Loads of fun team events, both in and out of the office

We look forward to welcoming talented new members to our team!
Our recruitment process consists of three stages: * A 30 min. phone interview with our People & Culture team member to discuss your general career motivations, and present our company and this role.

• A 1-1.5 hour phone interview with 1-2 members of the hiring team to deep dive into the core skills requirements.
• An on-site visit to interview with and meet many members of the team that you would be working in. This often includes lunch and gives you a strong sense of the company culture and individuals.

Then, both parties take their decisions! We aim to complete all steps in one month, but also allow for modifications to ensure both sides have a full picture of the skills and culture match to take the decision in an informed way.
Tip: the cover letter is optional, but it is a great way for us to know why you are applying. Taking the time to add a paragraph to a plain document to upload is not only totally fine, but much appreciated! No need for formal formatting, as we are an informal team that appreciates authenticity.
