Description
api design
api governance
tool integration
api gateway
metadata modeling
secure integration
The position focuses on creating and governing API contracts that modularize the simulation core and bring legacy tools into modern service‑oriented architectures. You will be responsible for designing secure, repeatable integrations across tools, data, and orchestration layers.
Work is performed on‑site, hybrid or remote with up to 15 % travel and standard working hours. The role requires coordination with cross‑functional teams to deliver high‑quality software solutions.
- Define and govern API‑first contracts that modularize the simulation core and onboard legacy tools as modern services.
- Ensure transparency, repeatability, and security across all integrations, including tools, data, metadata, and orchestration.
- Design REST/gRPC APIs and GraphQL schemas for core simulation services such as timing, state‑of‑play, user input, and orchestration.
- Lead API governance covering versioning, schema evolution (OpenAPI/JSON Schema/proto), deprecation policy, and documentation.
- Wrap existing simulation and wargaming tools as secure web services via SDKs, standardizing OIDC/JWT authentication and mTLS.
- Implement API gateway patterns for routing, rate limiting, quotas, request validation, and zero‑trust controls.
- Model metadata and lineage, tagging tools/inputs/results, and expose reconciliation endpoints for verification, fidelity assessment, and repeatability.
- Apply data‑modeling, metadata/lineage design, and auditability practices for regulated domains.
- Access professional training and development programs to support career advancement.
