Senior Software Engineer | Product Foundations

Role overview Build backend services that help a cloud infrastructure platform establish reliable identity, accounting, auditability, pricing, and savings reporting. The role spans several teams and trust-critical systems: the work must keep customer access secure, financial records accurate, and high-volume data useful for timely decisions.

Responsibilities - Design, build, and operate backend services, primarily in Go, with a focus on correctness and maintainability. - Take features from technical design through implementation, testing, and production rollout. - Investigate complex production issues affecting security, billing, or customer trust; improve performance under high load. - Work with product and engineering partners to resolve ambiguous problems and help shape the roadmap. - Contribute to on-call coverage where the team requires it.

Requirements - Strong software engineering fundamentals, including sound abstractions and the ability to explain architectural decisions. - Production experience with Go, or strong systems programming experience in a comparable language. - Experience building or operating high-scale systems where errors in identity, billing, or financial data have real consequences. - Knowledge of API design, including versioning, compatibility, authentication, idempotency, and asynchronous patterns. - Practical experience debugging and tuning databases and services, including query profiling and index design. - Hands-on Kubernetes experience, end-to-end project ownership, strong written and spoken English, and comfort working in a changing environment. - Experience with AI coding agents and agent-assisted development workflows.

Nice to have - Multi-tenant identity systems, SSO, or enterprise protocols such as SAML, OIDC, and SCIM. - Production experience with billing, audit trails, notifications, feature flags, cloud pricing APIs, or Spot capacity data. - High-volume time-series systems, Kubernetes internals, CI/CD, or production observability tools.

Benefits and work setup - Remote-first work is available to applicants residing in Bulgaria, Croatia, Estonia, Greece, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, Slovenia, or Ukraine. Work authorization sponsorship is not available. - Listed gross salary is €6,500–€9,000, depending on experience, with additional on-call compensation and equity options. - Support includes a learning budget, equipment budget, extra time off, and time allocated for personal projects or development. Onboarding requires travel to Vilnius, with travel costs covered.
