Mid Fullstack Engineer (React, NodeJS)

SwingDev—a hippo company is the Polish branch of a fast-growing InsurTech product company – Hippo Insurance. 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 Fullstack Engineer (frontend leaning) 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: Join one of Hippo's two technical charters, our product-and-tech teams, each owning a specific business area. You'll work in a small, agile team with real influence over technical decisions.   CORE charter (Customer Onboarding, Retention and Engagement) – the team behind our mobile apps (iOS and Android) and Customer Portal, plus the backends that power them. You'll work alongside Mobile engineers who also know their way around backend and frontend, supported by dedicated QA and a Designer. Lots of UI-heavy, user-facing work.   Acquisition charter – this team introduces new customers to Hippo and guides them through their journey, from first impression to the right product choice. We gather key customer data early on and surface products in a personalized way to boost engagement, conversion, and awareness of Hippo's offerings. We work closely with Product, Marketing, and Data teams, feeding analytics and responding fast to their needs. What will you do?

You'll develop core components of our systems.

You'll work in an agile environment focusing on projects that are impactful on our business.

You'll partner daily with QA and Design on user-facing features.

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 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 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 across both frontend and backend, ideally with stack: React, Node.js, JavaScript, and TypeScript.

Possess a good, practical knowledge of at least one relational database system, e.g. PostgreSQL/MySQL/SQL Server.
