Software Engineer

You’ll design and run the traffic routing platforms that carry global-scale traffic for a global traffic infrastructure provider. This is deep networking engineering in Go: Envoy data planes, Go control planes, eBPF and kernel-level tuning, on systems distributed across the world., * Practical Rust, specifically for developing and maintaining Envoy WASM filters

• Working knowledge of C and/or C++ for low-level system integration and debugging

What’s in it for you

• Flexible working hours and a fully remote arrangement
• Professional growth through internal training sessions and a training budget
• Structured, hands-on onboarding to get you productive quickly
• A team of engineers who care about the craft
• The ability to move between projects over time

• Proficiency in Go, with extensive experience designing and building distributed systems
• Experience building and managing large-scale, geo-distributed networking software
• Solid hands-on experience with Envoy Proxy (data plane) architecture alongside a Go control plane
• Advanced knowledge of network protocols from L3 to L7, network infrastructure and observability
• Strong understanding of the Linux network stack, practical eBPF experience, and hands-on socket and kernel performance tuning
• At least 5 years of relevant experience for Mid, or 7 years for Senior

• 18,000 to 25,000 PLN per month, depending on level
• Fully remote
• Hiring at both Mid and Senior level

What you’ll actually do

• Design, build, deploy and optimise large-scale global traffic routing platforms
• Develop high-performance distributed traffic infrastructure and networking software
• Build and manage large-scale, geo-distributed systems
• Lead complex migrations of legacy network systems and codebases in large environments
• Develop core network routing tools
