About us
Solflare is one of the fastest-growing crypto wallets in the world. With around 4 million monthly active users and over $20 billion in digital assets secured through our platform, we’re building a powerful gateway to Web3. Founded in 2021, Solflare now has a team of nearly 150 people, with offices in Zagreb, Belgrade, and Novi Sad, plus remote teams across the globe. Our vision is simple but bold: a world where everyone uses a Web3 wallet and has full control over their assets – achieving true financial independence.
Our culture
At Solflare, we’re on a mission to empower people to truly own and thrive – starting with our own team. We take on bold challenges with curiosity, grit, and a deep sense of accountability. Here, progress means learning fast, solving smart, and showing up for each other without ego. You’ll join a team where we question the status quo, celebrate shared wins, and never settle for “just good enough.” If you’re excited by growth – yours, ours, and society’s – you’ll feel right at home.
The role
This is not a testing role in the traditional sense. We're not looking for someone to catch bugs at the end of the pipeline and hand them back. We're looking for someone to own how quality happens across the entire product. As we like to put it: QA owns the testing strategy, not product quality. Product quality is shared by Product and Engineering.
Your job is to make sure the whole system is set up so that everyone can build confidence in what we ship, from the moment a feature is designed to the moment it's released. That means enabling engineers to test effectively, driving a quality mindset across teams, and building the systems and processes that support it, not just writing and running test cases.
We think about quality the way our users experience the product: as complete journeys, not as a checklist of acceptance criteria. If you read this and think "quality is someone else's problem once I've logged the bug," this role isn't for you. If you think in terms of "can the user actually achieve their goal here, and how do I make the whole team confident that they can," keep reading.
This is a senior role because it demands ownership. Not the word, the behavior: seeing what needs to happen and making it happen without being told, working across Product, Engineering, Data as a matter of course, and taking responsibility for the testing strategy of a feature end to end.
