About the role

  • Design, implement and maintain fullstack integration features connecting Vibe’s platform with external partners (APIs, webhooks, tracking, data flows).
  • Build robust backend services and interface contracts (REST / gRPC), with proper error handling, retries, idempotency and observability.
  • Develop product-facing integration workflows (configuration, feedback, error states) that make complex technical integrations understandable for users.
  • Operate and troubleshoot integration components in production, using logs, metrics and monitoring tools to ensure reliability at scale.

Requirements

  • Proven experience as a Fullstack Engineer working on production systems
  • Strong experience designing and operating API-based integrations
  • Comfortable navigating both backend and frontend responsibilities
  • Solid production mindset: reliability, observability, debugging
  • Ability to work autonomously as a freelancer while collaborating closely with internal teams
  • Strong fluency in English
Benefits
  • Work on real, business-critical integrations, not side projects
  • High ownership on clearly scoped, high-impact systems
  • Technically demanding environment with pragmatic engineering standards
  • Direct collaboration with Product and Engineering on core platform capabilities
