Job description:
We’re looking for Senior Backend Engineers to join Vinted Payments Product - the financial product powering payments, payouts, balances and verification flows for millions of Vinted members.
Depending on your background and interests, you could join one of two teams:
- Verifications - the team building identity, eKYC and bank account verification systems behind Vinted Pay. Their work helps confirm that members are who they say they are, and that their bank account really belongs to them.
- Phoenix - the team building and scaling the core ledger systems at the heart of Vinted Pay. Their work ensures every money movement is recorded correctly and every balance is right.
Both teams work on business-critical, compliance-sensitive backend systems used at scale. We’re launching new markets, onboarding millions of members onto Vinted Pay, and building foundations that will support the platform for years to come.
Work in a compact product-engineering team with backend engineers, an engineering manager, a product manager and a decision scientist.
Build and operate backend services that directly support payments, payouts, verification, onboarding, balance activation and money movement across Vinted Pay.
Own topics end-to-end: from an unclear requirement to a written technical proposal, cross-team alignment, implementation, rollout behind feature flags and monitoring in production.
Improve and scale high-throughput services in Go, and connect them into reliable, always-on payment and verification flows.
Build resilient integrations with third-party providers, including API clients, callbacks, durable workflows, dashboards, SLA alerts and vendor-facing debugging.
Design systems that handle failure well: timeouts, provider outages, rate limits, retries, missing callbacks, inconsistent responses and data consistency issues.
Work with distributed systems concepts such as idempotency, at-least-once delivery, workflow orchestration, provider routing and consistency across services.
Handle sensitive financial and personal data responsibly, including PII tagging, log masking, retention and deletion requirements.
Use AI-assisted engineering workflows with tools such as Claude Code, Cursor, Codex and others to build, debug, investigate production issues and write plans or documentation.
See your code affect millions of members almost instantly. Our main branch is deployed straight to production on each merge, many times per day.
Write unit tests for the code you write and contribute to integration and E2E testing.
Own critical alerts and business metrics to design and maintain high-availability systems (targeting 99.99% uptime).
Participate in on-call rotations and support production systems used across Vinted Pay.
Work with technologies such as Go, Ruby, Temporal, Kafka, MySQL, Redis, OpenSearch, S3, OpenAPI-first code generation, testcontainers, Prometheus, Grafana, Kubernetes and AWS.
Requirements:
You have solid experience building and running…
