Job Description
Software Engineer building secure GraphQL APIs for Quantum ERP data. Extending .NET, Entity Framework, and Oracle integrations while optimizing performance and multi-tenant access.
Responsibilities:
- Design, build, and maintain GraphQL graph types, queries, mutations, and resolvers exposing Quantum ERP data
- Extend the Entity Framework Core data layer and Oracle package wrappers and repositories
- Write correct, performant queries against the Quantum Oracle schema
- Optimize GraphQL execution using DataLoader, sensible result limits, and efficient resolver work
- Maintain JWT-based authentication and authorization and enforce multi-tenant scoping
- Translate business-layer process steps into API behavior aligned with Quantum's business rules
- Write and maintain unit tests across API, business, and data layers
- Use benchmark projects to identify performance regressions
- Support the Angular client consuming the GraphQL API and keep the schema and client contract synchronized
- Contribute to worker scheduled tasks where API and background work overlap
- Document graph types, queries, and Oracle-side dependencies
- Participate in code reviews, weekly integration syncs, and discovery sessions
- Coordinate with Corridor / Aviate parity teams to avoid duplicate implementations
Requirements:
- 4+ years building production APIs in C# / .NET (ASP.NET Core or ASP.NET Web API)
- Strong object-oriented C# and a solid grasp of layered service architecture (data, business, API)
- Hands-on Entity Framework (EF Core or EF6) and strong SQL
- Comfortable reading schemas, writing efficient queries, and reasoning about ORM behavior and N+1 problems
- Oracle experience is a strong plus
- Practical understanding of API security: JWT / bearer tokens, authentication and authorization, and input validation
- Track record of writing unit tests and treating test coverage as part of the definition of done
- Comfort working against real business or ERP data models where correctness and auditability matter (finance, accounting, or inventory domains)
- Clear written communication and the discipline to document schemas and open questions
Benefits:
- Remote work
- Full-time employment
