Founded in 2008 in Lithuania and now a unicorn with 2,000+ employees across European offices.
You'll join the Engineering Experience domain within the Platform unit, which builds the tools, platforms, and golden paths that enable Vinted's entire engineering organization. The domain comprises several teams: CI/CD (code repository, continuous integration, build artifacts, deployment via ArgoCD), Development Environments & AI (cloud development environments like Spinup, AI-assisted engineering tooling), DevPortal (internal developer portal and service catalog), and Quality Engineering (test infrastructure, QA processes, metrics).
You'll be hired as a Senior Backend Engineer II to join either the Development Environments & AI team or CI/CD team, reporting to an Engineering Manager and collaborating across the domain.
Key responsibilities include: exploring and adopting AI-assisted approaches to improve development efficiency and quality; designing, building, and owning tools, services, and frameworks (using Go, Ruby, Kubernetes) that make development, delivery, and quality fast and reliable; ensuring hundreds of engineers across Vinted benefit from your output; making Vinted's codebase work well with coding agents through proper context, conventions, and scaffolding; building tooling and processes to handle complex problems like PR review load and AI-assisted merge pipelines; improving environments and pipelines so agents and engineers can validate changes rapidly; and owning solutions end-to-end from research to adoption.
Required qualifications: substantial experience designing, building, and operating backend systems, platforms, or developer tools at scale; heavy personal use of AI to boost your work and enthusiasm for helping others do the same; proven experience designing and shipping tools/platforms/services that other engineers depend on; ability to write clean, maintainable, testable code; understanding of how to make codebases work well with AI (context, conventions, guardrails, evaluation); knowledge of practical limits and risks of LLM-based tools; strong thought leadership, technical influence, and ability to mentor and drive adoption of best practices; passion for engineering experience and developer productivity; excellent English communication.
Desirable: hands-on experience with Go, Kubernetes, developer tooling, CI/CD systems, or platform-like teams.
