• Debugging skills, with a structured approach to problem\-solving


• Ability to collaborate effectively and demonstrate curiosity for continuous growth


• Strong written and spoken English communication skills

• Experience with NestJS framework and ORMs like Prisma

• Exposure to messaging systems (e.g., RabbitMQ, Kafka)


• Awareness of cloud and container platforms (AWS, Docker)


• Background in e\-commerce or digital customer platforms


• Knowledge of observability tools (monitoring, logging, tracing)

• 2\+ years professional experience in backend development


• Practical experience with Node.js in production environments


• Familiarity with TypeScript, or strong commitment to learn it


• Experience building and consuming REST APIs


• Solid understanding of SQL and relational database fundamentals (PostgreSQL preferred)


• Comfort using Git workflows for collaborative development


• Exposure to Agile principles; willingness to work in a LeSS\-inspired multi\-team structure

• Permanent contract.


• Flexible Schedule. We make it easy. Balance your professional and personal life.


• Trainings \& Certifications. Improve your skills and get the official certificate from our main partners.
