Senior Software Engineer (Dot Net Core & API Integration)

As a skilled Senior Software Engineer with expertise in .NET Core API integration, your role will involve building, maintaining, and enhancing scalable web applications. You will collaborate with cross-functional teams to develop high-quality software solutions that prioritize performance, security, and maintainability. Key Responsibilities: - Analyze, understand, and map complex, heterogeneous third-party APIs into normalized data models. - Design and build connectors/integrations for SaaS platforms, field-specific APIs, and proprietary vendor APIs. - Develop and maintain data transformation and normalization pipelines that abstract away vendor-specific differences. - Handle authentication and authorization flows across diverse providers (OAuth2, API keys, SAML, custom flows). - Build resilient integration patterns that gracefully handle API inconsistencies, rate limits, and error behaviors. - Collaborate with product teams to design consistent, unified API schemas that scale across multiple providers. - Establish strong testing, monitoring, and logging frameworks for integration reliability. - Mentor and guide engineers in best practices for integration architecture and abstraction design. Qualifications Required: - 4+ years of backend engineering experience, with significant time spent in API-heavy environments. - Proven ability to reverse-engineer poorly documented APIs, understand complex JSON/XML payloads, and resolve mapping challenges. - Deep experience with API normalization, data modeling, and abstraction design. - Expertise with REST, GraphQL, and event-driven integrations. - Strong knowledge of integration middleware, API gateways, and webhooks. - Familiarity with async processing, queuing systems, and retry strategies. - Excellent problem-solving skills in handling edge cases, non-standard implementations, and schema drift. Additional Company Details: The company values individuals experienced in API-first engineering and comfortable working with complex data structures, integrations, and scalable system design. Nice-to-have qualifications include experience working at or integrating with unified API platforms, familiarity with domain-specific APIs (e.g., PRISM, HRIS, ATS, CRM, Healthcare APIs), knowledge of schema evolution strategies, versioning, and API governance, and background in ETL/data pipelines or interoperability standards (e.g., OpenAPI, JSON Schema).
