Job description

Brief info about Vinted

Our mission is to make second-hand the first choice, and we're looking for people who want to help us get there. Every day, we work together to help our members buy and sell pre-loved clothing and lifestyle items, giving each piece a second life – or even a third. The Vinted Group is made up of three business units that support this mission: Vinted Marketplace is Europe’s leading platform for second-hand fashion and a go-to destination for all kinds of pre-loved items, with a growing range of categories. Our platform connects millions of members across 20+ markets, helping great items find a new life. Vinted Go enhances the shipping experience with a vast network of over 500,000 pick-up and drop-off points, partnering with more than 60 carriers across Europe, with added services like item verification for peace of mind on high-value pieces. Vinted Pay is the newest part of the Vinted Group, dedicated to bringing secure, reliable payments to buyers and sellers across Europe. Seamlessly integrated into the Vinted app, it helps keep every transaction safe, efficient, and easy for our members. Founded in 2008 in Lithuania, Vinted began as a way for friends to find new homes for clothes they no longer needed. In 2019, we became Lithuania's first unicorn! Today, our headquarters remain in Vilnius, and we've grown with offices across Europe, supported by a team of over 2,000 people.

Information about the position

We're hiring a Senior Backend Engineer II to join the Engineering Experience domain in Vinted's Platform unit. Our domain builds the tools, platforms and golden paths that the rest of Vinted Engineering relies on every day - from the first line of code an engineer writes to the moment it runs safely in production.

Engineering Experience is made up of several teams, each owning a part of the engineering workflow:

CI/CD owns the flow from commit to production: code repository hosting and continuous integration, build artifacts and secrets, and deployment through ArgoCD - built and run in-house as self-service products for every engineering team.

Development Environments & AI is responsible for development environments and the engineering AI tooling ecosystem. Its flagship is Spinup, a cloud development environment that lets engineers and coding agents validate changes in remote environments without the complexity of managing local services. The team also leads the adoption of AI-assisted engineering across the company.

DevPortal builds Vinted's internal developer portal - the service catalog and self-service workflows that give every team clear ownership and one place to provision and operate their services.

Quality Engineering delivers tooling and processes for effective quality assurance across Vinted, from test infrastructure to reporting and quality metrics.

You’ll join one of these teams - Development Environments & AI or CI/CD. You’ll report to your team's Engineering Manager and collaborate closely with the other Engineering Experience teams. As a member of this domain, you will suggest, design and implement solutions for fast and reliable development, integration, delivery and quality, and ensure their successful adoption across the organisation.

In this position, you’ll

• Explore, adopt and enable AI-assisted approaches for your own delivery and to improve the efficiency and quality of others across Vinted's software development life cycle
• Design, build and own tools, services and frameworks that make development, delivery and quality fast and reliable, using technologies such as Go, Ruby and Kubernetes
• See your output used by hundreds of other engineers across Vinted
• Make Vinted's codebase work well with coding agents - the context, conventions and scaffolding that raise the quality of AI-generated code
• Build tooling and introduce processes to handle complex problems, such as growing pull request review load, AI assisted PR-merge pipelines, etc.
• Improve environments and pipelines so agents and engineers can validate changes in seconds instead of managing services on their own machines
• Own your solutions end-to-end, from idea and research to wide adoption

About you

• You have substantial experience designing, building, and operating backend systems, platforms, or developer tools used at scale
• You heavily use AI to boost your work, and you're keen to help other engineers do the same
• You have proven experience designing and shipping tools, platforms or services that other engineers depend on
• You write clean, maintainable and testable code
• You know how to make a codebase work well with AI - the context, conventions, guardrails and evaluation that raise the quality and safety of AI-generated code
• You understand the practical limits and risks of LLM-based tools and design around them
• You exhibit strong thought leadership in your area and have opinions about how things should be done, you can influence technical direction, mentor others and drive adoption of best practices across teams
• You are passionate about engineering experience and developer productivity
• Excellent written and spoken English
• It's a plus if you have hands‑on experience with Go, Kubernetes, or building developer tooling and CI/CD systems
• It's a plus if you have experience working in platform‑like teams
