Job Summary
In this role, you support customers in integrating our E-Invoicing API across Europe and prepare for our entry into the Polish market by analyzing API errors and providing solutions.
Job Technologies
Your role in the team
- You will be the primary technical guide for customers integrating our E-Invoicing API.
- This role combines immediate impact with strategic growth: you will support our existing European customer base (Italy, Spain, France, and Germany) while acting as the key "Subject Matter Expert" for our upcoming expansion into the Polish market.
- Your mission is to ensure readiness for the KSeF mandate and guarantee that customer data moves seamlessly from their systems to the tax authorities.
- You will spend your day deep-diving into JSON payloads, XML files, and API logs to understand exactly why a transaction failed.
- We expect you to work smarter, not harder, leveraging AI tools to parse complex validation reports and generate code snippets that solve problems instantly.
- You are not just a support agent; you are a troubleshooter, a teacher, and a technical advisor.
- Guide customer development teams through the technical integration of our API across our active markets.
- You will help them map internal data to standard formats like Peppol BIS, UBL, or FatturaPA.
- As we ramp up for Poland, you will test and support specific Polish integration flows (e.g., mapping to the FA(2) structure for KSeF).
- Analyze and resolve complex validation errors.
- You tell the customer exactly which field is missing or malformed, whether it's a VAT ID in a Spanish invoice or a session token for a Polish gateway.
- Assist customers in debugging their integration using tools like Postman or cURL, offering actionable technical insights rather than generic advice.
- Create developer-centric documentation.
- You might write a guide on "Handling Cross-Border VAT" today, and a guide on "How to authenticate with KSeF via fiskaly" tomorrow.
- You will identify technical friction points in our API and report them to Product and Engineering—specifically ensuring our product fits the needs of the Polish market.

Our expectations of you
Qualifications
- You are comfortable working with REST APIs and have a deep understanding of data formats like JSON and XML.
- You are not afraid of opening a large XML file to find a syntax error.
- You know your way around developer tools (Postman, cURL, Log Analysis tools).
- If you have knowledge of the Polish KSeF system, that is a game-changer.
- You are patient and clear.
- You can explain a schema validation error to a non-technical project manager.
- You prefer automating solutions.
- You use tools to speed up your work rather than doing manual checks.
- English and Polish are mandatory for this role.
- Fluency in German, Italian, Spanish, or French is a strong plus.
Experience
- Experience with EDI, ERPs, or E-Invoicing standards (Peppol, XRechnung, FatturaPA) is a massive advantage.
