As an Engineer, you serve as a technical specialist delivering the engineering that powers the product. You develop keen insight into the technical architecture and design to deliver robust and scalable software components. You constantly demonstrate the depth of your expertise by solving engineering problems. You are passionate about the quality of software and balance between speed of delivering new features and robustness of the software components you implement. You can handle operational issues with little or no oversight. You actively review code to ensure the software quality and functional accuracy is maintained across the team. You are keen to learn the design and architecture of the product and participate in ceremonies that can influence both. API Platform Team The Engineer, API Platform builds and operates the core infrastructure that enables secure, scalable, and high-performance APIs across the enterprise. This role focuses on developing platform capabilities that power API onboarding, traffic management, governance, and developer self-service. As an Engineer, you contribute to the design, implementation, and automation of API platform components, applying distributed systems principles to deliver reliable, observable, and secure API infrastructure. This is a hands-on engineering role focused on building scalable, secure, and automated API platform capabilities that support enterprise-wide development. Key Responsibilities API Platform Engineering Build and maintain API platform infrastructure leveraging HAProxy, with forward-looking adoption of Envoy Proxy. Implement advanced L7 traffic management including routing, rate limiting, retries, circuit breaking, and traffic shaping. Support TLS/mTLS termination and certificate lifecycle management. Enable progressive delivery patterns such as blue/green and canary deployments. Automation & Platform Tooling Develop automation using Ansible for provisioning and configuration management. Build Golang-based tooling for API onboarding, configuration validation, and lifecycle management. Implement CI/CD pipelines for automated configuration validation and secure deployments. Drive infrastructure-as-code and standardized deployment practices. Observability & Reliability Implement metrics, logging, and distributed tracing across platform components. Monitor and improve SLIs/SLOs for API availability and latency. Participate in incident response, root cause analysis, and reliability improvements. Security & Governance Implement authentication and authorization controls (OAuth2, JWT, mTLS). Enforce API governance and policy controls at the platform layer. Partner with security teams to integrate WAF and edge protection capabilities. Use your skills, experience and talents to be a part of groundbreaking thinking and visionary goals. As an engineer, you’ll take the lead as you… Use your technology acumen to provide input to assist with evaluation of new technologies and contribute to the design, lifecycle management, and total cost of ownership of services.
