Senior Backend Engineer (Go) (Incogni)

Join the Incogni engineering team and help us build the next-generation backend platform powering Incogni and Ironwall at scale.

We’re looking for a senior backend engineer who thinks in systems, designs for growth, and enjoys building reliable, scalable services.

Our mission is to create a secure, scalable, and high-performance service platform that supports rapid business growth and evolving product needs. You’ll work on core systems and service architectures at the heart of our platform, with Go as a key technology.

If you want to:

• Design, build, and evolve high-traffic, business-critical backend services (primarily in Go);
• Lead and influence architectural decisions — from domain modeling and service boundaries to infrastructure and deployment strategies;
• Drive the evolution of our service platform together with senior and lead engineers;
• Identify performance bottlenecks and scalability challenges, and propose pragmatic, long-term solutions;
• Own complex technical initiatives end-to-end, from design to production rollout;
• Write clean, well-tested, production-grade code while raising engineering standards across the team.

And you can check off:

• Strong experience building production-grade backend systems;
• Solid understanding of software design principles, distributed systems, and API design;
• Experience with databases, messaging systems, and service-oriented or event-driven architectures;
• Ability to reason about concurrency, performance, and reliability;
• Confidence participating in architectural discussions and technical decision-making.

Bonus points if you:

• Have experience building or scaling systems serving millions of requests;
• Leveraged hands-on production experience with Go;
• Developed a strong understanding of observability, reliability, and operational excellence;
• Contributed to modernizing or evolving backend platforms.

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 with a physical coach and sports card 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;
• Convenient commuting: traveling from point A to point B in a city like Warsaw is quite a journey! That’s why we compensate your public transport costs;
• 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;
• Premium Surfshark accounts: for you, your family, and friends;
• Gross salary: 24000-33400 Pln/month. Although it may vary depending on your skills and experience.
