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 Senior 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. 🚀 What will you do? You'll architect and implement backends and their interactions with various data stores and other APIs (including 3rd party APIs). You'll work in an agile environment focusing on projects that are impactful on our business. You'll support reliable databases and APIs for real-time automated decision-making. You'll deploy your software using industry-standard tooling like Kubernetes clusters, and Lambda functions. You'll investigate and resolve production issues by analyzing code, data, and system behavior and then propose and implement timely fixes to minimize user impact. You'll care deeply about security in everything you do and constantly raise the baseline of how we defend our user's data against external threats and themselves. You'll implement robust automated test suites to ensure high quality and low failure rate of delivered code. You'll work in a DevOps style to make sure Defense in Depth principles are followed and containers are as secure as humanly possible. You'll work closely with Product Managers, Senior Engineers and Architects 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 huge creative freedom and ability to put your mark on the project, and you will take ownership and responsibility for what you do. 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. We might be a match if you… Have at least 5 years of hands-on experience with Node.js, JavaScript, and TypeScript.

Treat AI-assisted development as a core part of how you work – Cursor, Claude Code, Codex or similar are in your daily setup. You have strong instincts for where AI accelerates both speed and quality vs where critical judgment has to lead. Have a good command of English (written & spoken).
