We are all dedicated to creating superior photonic products to solve hard problems in the field of communication as a big team effort.

We offer a variety of benefits to create a positive experience at work, and enable a healthy and enjoyable work-life balance.

• ZVV (Zürich region) annual transport pass and Halbtax
• 2 additional parental leave weeks,
• Flexible hours and hybrid work possibilities,
• On-site fitness room, canteen, and top quality espresso machine,
• and a lot of fun team events!

We look forward to welcoming talented, new members to our team.

Our recruitment process consists of three stages:

1. A 30 min. phone interview to discuss your general career motivations, and present our company and this role.
2. A 1-1.5 hour phone interview with 1-2 members of the hiring team to deep dive into the core skills requirements.
3. 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.

We built our company culture from day one, step by step, with the direct contribution of all our employees. Our culture finds its foundation in two core values:

• "Run, Don't Rush" emphasizes the importance of maintaining a steady, purposeful pace to achieve excellence without compromising quality.
• “It’s BTO: It's Better Together" highlights our commitment to teamwork and the belief that the only way to achieve our goals is by working in harmony and supporting each other.

At Lumiphase, we believe diversity strengthens our ability to achieve our mission. We are committed to fostering an inclusive environment where all individuals—regardless of race, ethnicity, gender, age, sexual orientation, physical ability, socio-economic background, or any other characteristic—feel valued, respected, and empowered.

Studies suggest that people from underrepresented groups, including women, often hesitate to apply unless they meet every listed qualification. If this role excites you but you’re not sure you check every box, we’d still love to hear from you. You might be just the person we’re looking for.
