• Design and govern NEF, SCEF, and CAMARA compliant APIs, ensuring alignment with 3GPP and GSMA standards.
• Partner closely with network, platform, product, and security teams to translate complex telecom concepts into clean, developer friendly interfaces.
• Define and enforce API standards for scalability, performance, security, versioning, and lifecycle management.
• Drive API design decisions across REST, OpenAPI, GraphQL, gRPC, and event driven architectures.
• Ensure APIs support high throughput, low latency enterprise grade workloads with strong observability and resiliency.
• Provide technical thought leadership and mentorship across a diverse, cross functional engineering organization.
• Review designs and implementations to ensure consistency, quality, and best practice adoption.
• Evaluate emerging technologies, standards, and industry initiatives to inform long term network exposure strategy.
• Represent API architecture in internal forums and external partner discussions as a subject matter expert.

Qualifications

• 10+ years of experience designing and building enterprise scale APIs and distributed systems.
• Hands-on experience exposing 4G/LTE and 5G network functions, capabilities, and telemetry to external services.
