About Zenniz

We’re building the future of tennis with innovative smart tennis court technology. The Zenniz smart tennis court system helps tennis players, coaches, and clubs with electronic line calling, match analysis, video tools, and gamified drills. Our system turns raw video and sensor data into real-time line calls, analytics and insights, which power the Zenniz platform that helps people play, learn, and enjoy the game more.

The position

We’re expanding our team and are looking for a Customer Support Lead to take ownership of all customer support at Zenniz.

We are looking for someone who not only has the ability to coordinate and take the lead in solving customer-facing issues, but also someone who has a customer service mind and is willing to go the extra mile in supporting the customer. This role will be central in building the customer service foundation at the company.

In this role, you will be responsible and  the primary owner of customer-facing issues from first contact through full resolution. You are responsible for ensuring that our customers receive clear communication, quick responses, realistic timelines, and high-quality resolutions to their concerns. While you won’t be expected to solve every technical or hardware problem yourself, you will be responsible for making sure that every issue gets resolved in a timely and professional manner with the help of our tech- and hardware teams

A key part of the role is close collaboration with our software and hardware teams. You’ll work across teams to track progress, follow up on open issues, and make sure nothing falls through the cracks. You’ll also play an important role in communicating customer pain points internally, helping the team understand what matters most to our users right now.

This role is a great fit for someone who enjoys responsibility, likes bringing structure to complex situations, and wants to grow into a role where they help manage and develop customer support as the company scales. We’re actively building a formidable customer support operation, starting with this hire in Finland, expanding customer support to North America and beyond later this year — meaning this role will help lay the foundation for how customer support works globally at Zenniz and you get to participate in this strategically important project.

What We’re Looking For?

We’re looking for a customer-service minded professional who takes pride in owning problems end-to-end and making sure customers feel heard and supported. You’re comfortable being the main point of contact, even when resolving an issue requires coordination between multiple teams.

You communicate clearly and confidently, both with customers and internally. You’re able to translate technical or hardware-related topics into understandable language, and you’re not afraid to ask questions when something isn’t clear. You don’t need to be deeply technical, but you should feel comfortable working closely with engineers and understanding the basics of how our system works.

You are passionate about furthering racquet sports through technology, and want the customers investing in Zenniz to thrive in their own operations.

You’re organized and proactive by nature. You follow up on open issues without being asked to, keep track of priorities, and take ownership of closing cases. You’re also able to look at the bigger picture — identifying recurring issues, summarizing trends, and clearly communicating what our customers are struggling with most.

We value people who take ownership, communicate openly, and want to continuously improve how things are done. Previous experience in customer support, customer operations, technical support, or a similar role is beneficial , but more importantly, your approach on how to solve an issue from the beginning to the end matters more.

It is important that you thrive in an ambitious and fast paced environment, get energized rather than flustered by tackling challenges and enjoy working together with others in planning and building world leading solutions.

You don’t need to be a tennis expert, but a genuine interest in tennis is important for this role. Understanding the context in which our products are used will help  you in better supporting our customers. We work in an international environment, so you should be comfortable communicating in English. Finnish and other language proficiencies are a plus.

We welcome candidates with different backgrounds and levels of experience. If this role sounds exciting to you, we encourage you to apply even if you don’t meet every expectation listed above.

Why Zenniz?

At Zenniz, you’ll work on a product that has a real, visible impact on how tennis is played and experienced. Our technology is used on courts around the world by players, coaches, and clubs who rely on it during training and competition every day.

Sports are at the core of what we do. We create industry leading premium solutions and are pioneering the future of racquet sports. We are racquet sport players and coaches ourselves, creating our services for players by players.  We care deeply about performance, fairness, and improvement, and those values shape how we build our products and how we work as a team. You’ll join a group of people who are motivated by creating high-quality experiences and pushing sports technology forward.

We’re a close-knit team that enjoys spending time together beyond day-to-day work. From tennis tournament trips and after-work sports to the occasional video game session, we value the shared experiences that build trust and make collaboration easier. We value a healthy work-life balance and support all team members in finding the best way for them to operate and thrive throughout our journey.

We offer a competitive monthly salary depending on experience, along with benefits and the possibility of stock options. If you’re excited about building impactful products at the intersection of technology and sport, Zenniz is a place where your work truly matters.

Practicalities

In this full-time and permanent position you will be employed directly by Zenniz. The start time in the role is as soon as possible. We value in-person collaboration and encourage regular time at our Helsinki office, while still supporting a hybrid way of working.
