  • Familiarity with REST APIs, JSON, and integration workflows.

  • Experience with Git and DevOps-friendly development practices.

  • Understanding of Agile/Scrum methodology and sprint delivery.

  • Problem-solving mindset and ability to design efficient solutions.

  • Solid knowledge of data structures and algorithms.

  • Fluency in Polish and English (working in an international team and with APAC clients).

Nice to Have:

  • Exposure to Low Code / No Code platforms (e.g., Neutrinos, Mendix, OutSystems).

  • Basic understanding of Docker/Kubernetes and microservices architecture.

  • Familiarity with BPM tools, API orchestration, and system integrations.

  • Experience in the insurance or financial services (BFSI) domain.

  • Strong verbal and written communication skills.

Why join us?
