What we offer?
At Jotelulu, we’re building something big, and we want you to be part of it.
We don’t do red tape or endless layers of approval. Here, ideas move fast, and your opinion actually counts.

We believe in flexibility and balance, because work is part of life, not the other way around. Whether you’re at home, in the office, or anywhere in between, what matters most is the impact you make.

You’ll join a team that’s growing and learning together, where challenges are real, but so are the opportunities to stretch your skills and shape your career path. We’ll give you the tools, the trust, and the feedback to help you keep moving forward.

Our culture is inclusive, friendly, and refreshingly down-to-earth. No suits, no egos, just a bunch of people who enjoy what they do and respect each other’s individuality.

We also take care of the essentials: access to quality healthcare, a transparent feedback culture (including regular 1:1s and performance reviews), and open communication through company-wide updates.

We also take care of your well-being:
- Private health insurance with access to a top-tier medical network.
- A friendly, inclusive culture where everyone can be themselves.
- Casual dress code (yes, t-shirts and sneakers are perfectly fine).
- Team gatherings and informal events to celebrate milestones and recharge together.
- We would love to hear from you and have the opportunity to work together.
