System Engineer- Platform​/API Gateway

The Systems Engineer Platform – API Gateway is responsible for developing, managing, and optimizing enterprise API platforms using both Apigee and Kong. This role ensures secure, scalable, and highly available API traffic across cloud and on‑prem environments, supporting enterprise integration and modernization initiatives. The engineer will operate and evolve a dual‑gateway strategy, supporting Apigee (cloud‑native) and Kong (on‑prem / hybrid / cloud), while enabling standardization, observability, and long‑term migration.

This is an on‑site position located in Springfield, MO.

Design and build secure, high-performance APIs for distributed systems. Define API specifications (OpenAPI/Swagger), enforce consistent standards, and implement traffic management (rate limiting, transformations, logging). Develop API functionality in Java/Python, integrate with microservices and third‑party systems, and optimize for GCP services (Cloud Functions, Run, Pub/Sub, Storage).

Manage API gateways (Apigee X, Kong) including proxies, portals, and platform infrastructure across cloud and hybrid environments. Monitor performance, troubleshoot issues, and optimize reliability, latency, and scalability. Develop custom policies/plugins and improve developer onboarding through well‑designed portals and documentation.

Automate infrastructure with Terraform and build CI/CD pipelines (Jenkins) for API proxies and gateway configurations. Support secure, multi‑environment deployments with integrated testing, approvals, rollback, and connections to Git, secrets management, and artifact repositories. Leverage GCP tools for scalable pipeline operations.

Implement API security using OAuth2, JWT, SAML, and API keys, integrated with identity providers (Okta, Azure AD). Enforce compliance (PCI, SOC2, HIPAA), apply OWASP best practices, and adopt Zero Trust principles using mTLS, IAM, and network controls to protect data and access.

Monitor APIs using tools like Prometheus, Grafana, ELK, and GCP observability services. Track performance metrics, detect anomalies, and optimize latency and reliability. Define alerts, automate remediation, support on‑call operations, and lead incident analysis.

Work across architecture, Dev Ops, and security teams to ensure aligned API design and governance. Mentor engineers, promote API‑first development, and contribute to design reviews, resilience testing, and product alignment.

Manage the full API lifecycle from design to retirement. Maintain API catalogs, enforce governance standards (naming, access, SLAs), and ensure alignment with GCP policies and audit requirements.

Stay current with API and cloud trends, evaluate new tools, and lead PoCs to improve performance, security, and developer experience. Continuously refine services for better scalability and reuse.
