Helsinki, Finland (Hybrid) · Full-time, Permanent · Apply by 22nd of March 2026
ABOUT ZENNIZ
We're building the future of tennis - one Smart Tennis Court at a time
Zenniz makes tennis courts intelligent. Our system delivers electronic line calling, real-time match analysis, video tools, and gamified drills by turning sensor data and video into insights that help players, coaches, and clubs perform at their best.
We are used on courts around the world, and we are growing fast. This year, we are expanding our customer support operation from Finland into North America and beyond. This hire is where that starts.
THE POSITION
You own every issue from first contact to full resolution
You're the person who decides how customer support works at Zenniz. The processes, the tone, the standards, and eventually the team. You'll be the primary point of contact for our customers globally, the internal voice for their needs, and the foundation for a support operation that will scale across multiple continents.
What you'll actually do:
Own all customer-facing issues end-to-end - first contact, coordination, resolution, and follow-up
Be the primary liaison between customers and our software and hardware teams
Ensure every open issue has a clear owner, a realistic timeline, and professional communication at every step
Build and document the systems, workflows, and playbooks that will scale as the team grows
Track and synthesize recurring issues, surfacing the most critical customer pain points to the product and engineering teams
Help define how customer support will operate globally as we expand to North America and beyond later this year
WHO YOU ARE
A natural owner who gets quality across the finish line
You take pride in problems being fully solved - not just acknowledged. You communicate clearly with both frustrated customers and busy engineers. You're organized without being rigid, and you care about the person on the other end of every conversation.
You have experience in customer support, customer operations, or technical support; the level matters less than your instinct for ownership
You communicate confidently with both customers and technical teams, translating between the two without losing nuance
You follow up without being asked, keep track of competing priorities, and don't let things fall through the cracks
You're comfortable in an early-stage environment where you're building the map, not following one
You have a genuine interest in tennis or racquet sports - you don't need to be an expert, but understanding the context our customers play in will make you better at the job
You're fluent in English; Finnish or other languages are a welcome bonus
COMPENSATION
We offer a competitive salary along with benefits and stock options.
WHY ZENNIZ
A team that takes both the work and the game seriously
Real product, real courts: Our technology is live on courts globally, used during real matches and training every day - not a pilot or a prototype.
Global from day one: You'll be expanding into North America before the year is out. This role shapes how support works globally, not just locally.
Build, don't inherit: No legacy systems to work around. You're defining how this function works, with the autonomy to do it right.
A team that actually plays: Group tennis, after-work sports, and the occasional ping-pong sessions. We spend time together because we enjoy it.
Hybrid that actually works: We value in-person collaboration at our Helsinki office and support the way each person works best.
Grow with it: As Zenniz scales, this role scales as well. The person who builds the foundation is best placed to lead what comes next.
