We’re here to make home insurance smarter and more proactive, using tech to bring fresh solutions. We also create digital products that support our customers, always focusing on what really makes an impact.   Putting a lot of effort into hiring top-tier professionals is a proof that we care a lot about tech experience, the attitude, human approach, and what we could call „culture fit”.   „SwingDev is all about people” - yes, it may sound a bit cliche. But whether we're writing code or just hanging out, we know that people are at the heart of everything we do. We like to have a good time and keep things light, even when we're tackling big projects. We could brag about what’s making us special, but we’ve boiled it down to two key ingredients: mature, companionable people who, rather than compete, prefer to inspire and have each other’s backs; a culture of trust, empathy, and positivity that keeps us together, lets us interact as teammates and friends, and truly enjoy the ride.   So if you're a Mid Back-end Developer looking to shake things up and have a good time while you're at it, you’ve come to the right place. 🚀 About the role: At Hippo Insurance, we’ve got almost 20 tech charters up and running — and we’re still growing fast.

You'll work closely with Product Managers, Senior and Staff Engineers to understand business processes, rules, and requirements, and turn them into high-quality code with automated tests, and deploy them to production.  You’ll have a lot of chances to develop your programming skills as well as learn a lot about how tech business is done in the US (if you want to).  We might be a match if you… Have at least 3 years of hands-on experience with Node.js, JavaScript, and TypeScript. Possess a good, practical knowledge of at least one relational database system, e.g. PostgreSQL/MySQL/SQL Server. Can engage in discussions and decisions regarding software design and architecture.

Show readiness to learn and expand your skill set as required by ongoing projects. Have a good command of English (written & spoken). Are available to work in different timezones – we prioritize everyone’s personal time and work-life fit, but since we work across Poland and the US (Austin, San Francisco), occasional evening meetings may be necessary (on average 2 days per week).
