We’re building HeyPolo - a privacy-first smart location-sharing app that helps families and friends stay connected, and safe. HeyPolo is designed for meaningful connection without intrusive tracking: real-time updates, consent-based sharing, and intuitive safety features that put users in charge of their data and peace of mind.

If you’re excited by real user impact, privacy-centered innovation, and building something from scratch with a small, autonomous team, read ahead.

IF YOU WANT TO:

- Architect, build, and own the server-side logic of the new application;

- Lead the design and implementation of backend features and APIs using .NET/C#;

- Focus on writing clear, tested, documented code that delivers real business value;

- Ensure responsive and reliable service through scalable architecture.

AND YOU CAN CHECK OFF:

- Proven experience as a Senior Backend Developer, specifically with .NET/C#;

- Strong understanding of OOP, design patterns, and modern .NET frameworks;

- Experience with RESTful API design and implementation;

- Experience in building highly scalable systems;

- Proficiency with database design and management;

- Background in microservices architecture;

- Familiarity with DevOps practices;

- Excellent problem-solving skills and attention to detail;

- Strong communication skills and a team-oriented mindset.

HERE’S THE DEAL:

- Growth and learning opportunities: time dedicated to learning, conferences, online learning platforms, and books for your professional development;

- Health and wellness: we want you to feel and be your best. That's why we offer various benefits, from online workouts and a physical coach to health insurance and regular mental health checks;

- Tools of your choice: choose the technical equipment and tools you need to do your best work;

- Community and celebrations: get ready for long-lasting traditions such as yearly workation, Friday get-togethers, various team buildings and company celebrations;

- Work-life balance: We encourage working in the office, with the possibility of up to two remote days per week. Plus, with our WFA policy, you can work from almost anywhere in the world;

- More days off: additional vacation days depending on your tenure;

- Premium Surfshark accounts: for you, your family, and friends;

- Gross salary: 5000 - 7000 Eur/month. Although it may vary depending on your skills and experience.

About Surfshark

Surfshark is the Vilnius VPN and digital-privacy company, and hires for Incogni, its data-removal product, on the same board. Most posts are Vilnius: backend, mobile and data science next to a large brand and marketing org, so read the title carefully — a good half of the board is not engineering.
