You’ll work closely with Product, QA and other engineering teams while remaining deeply involved in architecture and coding.\n\nWhat You’ll Do\n\nDesign and build a new platform component from scratch.\n\nOwn architecture and key technical decisions through production implementation.\n\nDevelop core backend and infrastructure components primarily in Go.\n\nWork with the platform’s data plane, distributed systems and data flows.\n\nBuild scalable, reliable services using Kubernetes and cloud-native infrastructure.\n\nWork with PostgreSQL, APIs and service-to-service communication.\n\nProvide technical direction as the new engineering team grows.\n\nUse modern development approaches, including AI-assisted coding tools such as Claude Code.\n\nWhat We’re Looking For\n\nExperience as a Staff / Principal / Lead Engineer, Software Architect, or equivalent senior hands-on role.\n\nExcellent Go / Golang skills — core requirement.\n\nStrong software architecture and system design experience.\n\nProven experience designing and building complex distributed systems.\n\nStrong backend and infrastructure engineering background.\n\nHands-on experience with Kubernetes and cloud-native environments.\n\nExperience with PostgreSQL and production data architecture.\n\nGood understanding of data plane architecture, networking, APIs, concurrency, performance, scalability and reliability.\n\nAbility to turn ambiguous requirements into architecture and working production systems.\n\nHigh degree of technical ownership and independence.\n\nComfortable working in a fast-moving startup environment with a strong delivery focus.\n\nNice to Have\n\nPython and/or Java development experience.\n\nExperience with networking, cybersecurity or infrastructure platforms.\n\nExperience with microsegmentation, policy enforcement or similar network security systems.\n\nExperience with Claude Code or other AI coding agents.\n\nPublic technical leadership, such as conference speaking or engineering community contributions.\n\nOther details:\n\nLocation & Working Model\n\nCET timezone.\n\nKraków is preferred, with weekly office collaboration.\n\nStrong candidates elsewhere within the required time zone can be considered.\n\nB2B contract with a US entity.\n\nOutput-oriented working model.\n\nCompany laptop provided.\n\nInterview Process\n\n30-minute discussion with engineering leadership.\n\nTechnical deep dive with live coding and architecture discussion.\n\nFinal technical/culture discussion if needed.","description_format":"text","description_chars":2837,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Network
