We are seeking an experienced Java Backend Developer with strong data modeling skills to support a key transformation initiative at an enterprise level. The goal is to replace a complex and incomplete legacy system with a modern, clean REST API layer that integrates with Palantir Foundry.

You will work at the intersection of telecom-standard data models (TMF) and platform-native object modeling (Palantir). Your primary responsibility will be to implement a data access layer that translates TMF-compliant requests into SDK-based interactions with Palantir, following established logical models and helping define their physical implementation.

This is an opportunity to shape the architecture before the first production release and work in a long-term platform modernization effort.

• Design and build REST APIs in Java that act as a bridge between an orchestration application and Palantir Foundry
• Translate TMF-based logical models into physical object structures within Palantir
• Collaborate with platform engineers and architects to define scalable data access layers
• Work with SDKs (not just REST APIs) to interact with Palantir's backend
• Ensure clean code practices and scalable design from the start

• 5+ experience in Java backend development
• Proven experience in data modeling – logical and physical
• Familiarity with domain-driven design and telecom data models (e.g., TMF) or willingness to learn quickly
• Experience working with SDKs or platform-specific APIs

• Knowledge of Palantir Foundry
• Understanding of TMF (TeleManagement Forum) specifications
• Experience with platform-based development environments (e.g., Salesforce, Mendix, OutSystems)
• Familiarity with API security (OAuth 2.0, tokens)

• High-impact role in a multi-year transformation effort
• Work on a greenfield architecture before v1 goes live
• Long-term potential 
• No legacy maintenance – focus on clean code, scalability, and clarity
• Exposure to Palantir Foundry – one of the most in-demand enterprise data platforms
