Job description

Get to know us

At eyeo, we transform the internet into a trusted, sustainable and accessible place where users regain control over their experience, content creators and publishers are rewarded for their content, and advertisers and consumers can connect on mutually agreed terms.

With multiple brands across the ad tech space, eyeo offers solutions for publishers, advertisers, ad-tech solutions providers and over 400 million ad-filtering users worldwide. eyeo’s market-leading ad-filtering technology powers products like Adblock Plus and AdBlock as well as technical integrations for popular browsers and smartphone OEMs.

Our subsidiary, Blockthrough, is the most popular ad block recovery solution among the Comscore-150, offering premium demand via direct seats with top-tier SSPs, allowing effective content monetization and providing a platform where publishers and advertisers can efficiently transact.

We believe in creating a positive and empowering workplace where work-life balance is a priority. With a dedicated learning and development budget, you'll have the tools to grow and advance your skills, while contributing to clearly defined personal and company goals. Our people-first culture ensures you feel appreciated for your work and know that your contributions truly matter.

What you'll do

The Growth team is a collaborative group of engineers, product managers and marketing specialists passionate about building technical solutions that drive user growth and engagement across our consumer-facing products like AdBlock and Adblock Plus.

We're looking for a proactive and curious software engineer, with a strong front-end focus, who enjoys working across a range of platforms, including websites, web extensions and mobile apps. In this role, you'll help implement and iterate on growth experiments, contribute to product direction through data-driven insights and work closely with cross-functional teammates to ship meaningful improvements to millions of users.

We welcome applicants from all backgrounds and experiences. If you’re excited by the idea of rapid experimentation, creative problem-solving and making a real impact at scale, we’d love to hear from you!

Your day-to-day activities

• Rolling up your sleeves and diving into the code, even if it’s running on a platform you’re not yet familiar with. You shape and build experiments that aim to deliver real impact fast.
• Designing and building user-facing solutions is at the heart of the role. Whether it’s a website, a desktop extension or a mobile app interface, the goal is to create experiences that feel intuitive and seamless for our users.
• Working closely with product and engineering leads to help ensure that technical requirements and timelines are crystal clear. Keeping communication smooth and aligned across the board is key to moving fast without confusion.
• Implementing changes quickly, but not carelessly. There’s a strong focus on keeping the pace of experimentation high, while still maintaining the quality and stability of the codebase.
• Making data-driven decisions, rather than relying on gut feeling. Analyzing how users interact and respond helps fine-tune experiences and makes sure improvements actually land the way they should.

What you bring to the table

• Building engaging, user-facing interfaces is where the energy goes. Front-end work isn’t just part of the job, it’s a craft you genuinely enjoy.
• Running A/B tests, digging into the results, and letting the data guide what comes next is part of your everyday approach to shipping smarter, not just faster.
• Always up for learning something new? That curiosity shines when diving into areas like web extensions or mobile UI, even if it’s outside the usual comfort zone.
• Growth-focused collaboration isn’t a new thing. Working side-by-side with Product and Marketing to quickly ship value feels like a natural way of operating.
• HTML, CSS and JavaScript, are all familiar territory. And when it comes to building accessible, responsive experiences, you’ve got plenty of hands-on experience to draw from.
• A solid foundation in software engineering principles makes complex challenges feel approachable, especially with 3–5 years of experience under the belt.
• Deploying to the cloud? That’s not a blocker. Having used platforms like Google Cloud means you’re ready to get things live without breaking a sweat.
• Agile isn’t just a buzzword. Iterating, improving and keeping things moving is how progress happens - and how teams get better together.
• If there’s a blocker, you don’t sit on it but you loop in the right people and find a way to keep things moving without unnecessary delays.
• Comfortable figuring things out on your own, but never hesitant to grab a teammate for a quick chat when input or shared thinking is the better route.
• Being based in a CET ±3 timezone, making real-time collaboration with the rest of the team smooth and easy.

It’s awesome if you have

• Experience working on a browser extension or mobile app with a large user base
• A passion for creating positive user experiences and contributing to products that make a difference
• Experience mentoring or supporting other team members' growth and development
• Actively participated in or organized initiatives that promote diversity and inclusion in tech
• An interest in contributing to open-source projects or communities
• A strong sense of curiosity and a desire for continuous learning and skill development
• Experience with WordPress and Gutenberg
