  • Maintain and optimize backend infrastructure in cloud environments

  • Support automation flows and integration processes (Workato)

  • Collaborate with FullStack, Application, and Data Engineers

  • Support React / Next.js applications when required

  • Own features from concept through deployment

  • Provide maintenance and troubleshooting across backend services and integrations

Requirements

  • 5+ years of experience with TypeScript and Node.js (& Javascript ecosystem)

  • Strong experience with relational databases (PostgreSQL)

  • 2+ years of experience with React or React frameworks (Next.js)

  • Experience with cloud infrastructure (GCP preferred or similar)

  • Familiarity with Kubernetes

  • Experience with integration testing

  • Strong understanding of backend architecture, caching, and design patterns

  • Solid knowledge of security best practices

  • Proficiency with Git

  • Strong English communication skills

  • Ability to work independently and manage multiple initiatives

  • Experience working in international distributed teams

  • Preferably a university degree in Computer Science (or similar technical background)

Nice to Have

  • Experience with Workato or similar automation platforms

  • Experience with NestJS or Bun

  • Infrastructure as Code (Terraform)

  • Microservices architecture experience

  • Experience with caching solutions (Redis, Memcache)

  • Familiarity with SSO, Cloudflare, or Okta

  • Experience with Python

  • Experience documenting APIs (OpenAPI or similar)

    Recruitment Process

    1. Screening Call (30 min): A short introductory conversation with our recruitment team to discuss your background, motivation, and role expectations.

    2. Client Interview – Communication & Cultural Fit: A meeting focused on collaboration style, communication, and how you work in an international environment.
