Intern Integration Consultant

Location: Wrocław, Poland

Company: MasterBorn

Employment Type: Part-Time

Work Mode: Remote or Hybrid

About the Role

MasterBorn is a Polish-American software house building custom digital products for clients across Fintech, Sportstech, and Medtech. We're looking for an Integration Consultant Intern to join our team and support the technical side of client integrations - working with APIs, data, and documentation, and helping keep communication between our team and our clients clear and reliable.

Responsibilities

Support integrations between our clients' systems and the products we build - checking API requests and responses, and verifying data with SQL queries
Read and work with technical documentation, ours and our partners'
Investigate reported issues: reproduce them, narrow down what's actually broken, and summarize findings clearly for the team
Communicate directly with clients, in English, to clarify requirements and share updates
Use Git for day-to-day work: commits, branches, pull requests
Take ownership of assigned tasks, flag blockers early, and act on feedback

Requirements

Basics of programming in any language - TypeScript is a plus, but not a requirement
Understanding of APIs and HTTP - what a request and response are, GET/POST methods, status codes, JSON format
Basics of SQL - SELECT, WHERE, JOIN, reading a database schema
Git at a working level: commit, branch, pull request
Ability to read technical documentation in English with full understanding

Soft Skills

Proactivity - asks questions, raises blockers, doesn't disappear with a problem for three days
Attention to detail - spots inconsistencies, checks rather than guesses
Structured problem-solving - can clearly state what isn't working and what's already been checked
Written communication - summarizes findings clearly, writes understandable messages
Openness to feedback - takes it without defensiveness, applies it
Independence in assigned tasks
Fluency in Polish and English (min. C1 for both - it’s a must)
Active student status

Nice to Have

Hands-on experience with TypeScript or another backend language
Familiarity with asynchronous communication: webhooks, queues
Experience in fintech - working at a bank or around one
Experience leading meetings or workshops, in any context
Knowledge of Scrum / Agile / Lean Startup - even just theoretical
Experience creating technical documentation

We Offer

Start Date: ASAP
Time: approx. 6 hours/day (part-time), for 3 months with possibility of extension for another 3 months
Work mode: remote or hybrid (Wrocław office available)
Contract & Compensation: 4,300 zł brutto UZL (Prefer a B2B setup? Let's talk!)
Paid 3-month internship with real responsibilities
Option to extend the cooperation
Path toward an Integration Consultant role
Regular feedback, mentoring, and shadowing opportunities
A friendly, feedback-driven culture where you can ask anything and grow fast
Access to internal Tech Talks and knowledge-sharing sessions
Polish working hours and flexible arrangements
