About the job

Are you ready to craft a public API that serves as the backbone of a modern, ERP-agnostic P2P platform?


At 4CEE, you will contribute to the "digital front door" of our Purchase-to-Pay software: public APIs and ERP connectors that our customers and partners rely on daily. You will help redefine the API foundation to be consistent, scalable, and fully observable, enabling faster, safer, and frictionless new integrations.

Your Responsibilities:

As an API & ERP Integration Developer, you will be a co-owner of the new 4CEE public API and its associated ERP connectors. You will translate our API and integration strategy into robust software capable of handling high volumes and complex chains.

  • Design and build a generic, consistent 4CEE public API (domain modeling, version control, OpenAPI contracts)

  • Implement end-to-end observability: audit trails, traceability, status exposure, and correlation IDs across ERP ⇄ 4CEE Exchange ⇄ 4CEE Invoice

  • Enhance data integrity with asynchronous API processing, schema validation, retries, and dead-letter queue patterns

  • Create ERP connectors and P2P flows for platforms such as SAP S/4HANA, Microsoft Dynamics 365 (BC & FO), NetSuite, Unit4, AFAS, and Isah

  • Develop reusable connector patterns and deployment templates for rapid, consistent rollout

  • Establish API security and platform standards (OAuth2/OIDC, scopes, rate limiting, WAF, secrets)

  • Collaborate with CI/CD pipelines, conduct code reviews, and uphold quality gates within a professional cloud team

What We Are Looking For:

You are an experienced backend or integration developer who takes ownership of API design, reliability, and scalability.

  • Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field

  • At least 3 years of experience as a backend or integration developer

  • Proven experience with Python and AWS serverless architecture (Lambda, API Gateway, SQS/EventBridge)

  • Knowledge of API design, JSON/XML, schema validation, and observability principles

  • Experience with OAuth2/OIDC, JWT, and secure API integrations

  • You work methodically, document clearly, and maintain technical standards within the team

At 4CEE, you will build an impactful API foundation: your work enables clients and partners to realize new ERP integrations faster within a unified CFO platform.

What We Offer:

  • A salary ranging from €4,000 to €6,000 (based on 40 hours and your knowledge and experience)

  • The opportunity to make a technical impact, contributing to innovative features and solutions
