Senior API Platform Engineer

**Digital Transformation API Platform & Agentic Ecosystem**

📍 United States | Remote

🕒 Full-Time

🌍 ABOUT YPO

YPO is a global leadership community of 35,000+ chief executives across 142 countries, built on peer learning, shared experiences and trusted relationships.

Our digital transformation is building a platform where members can discover relevant peers and experiences, understand why they see what they see, control their data and trust every interaction.

At the center of that transformation is a modern data and intelligence platform - with APIs serving as the connective tissue across YPO’s digital ecosystem.

💡 THE OPPORTUNITY

We’re looking for a Senior API Platform Engineer with deep backend and API engineering experience to help build the platform powering YPO’s member ecosystem, chapter operations and emerging Agentic AI capabilities.

This is more than an API implementation role.

You’ll work through complex questions around API architecture, highly connected data, scalability, caching, consistency, performance, security and governance - and turn those decisions into production-quality solutions.

You’ll own technical implementation end-to-end, make thoughtful architectural tradeoffs and partner across Product, Data, IT and Security to build systems that are scalable, secure, observable and maintainable.

⚙️ WHAT YOU’LL DO

API Architecture & Engineering

• Design and build production-scale REST and GraphQL APIs using AWS API Gateway
• Create stable API contracts that remain decoupled from underlying data and backend schemas
• Design APIs over complex, highly connected and relationship-driven data
• Solve architectural challenges involving caching, data consistency, concurrency, latency and performance
• Define clear API and service boundaries using Domain-Driven Design principles
• Design for scalability, reliability, resilience, security and observability
• Implement versioning, backward compatibility and breaking-change strategies
• Build within a serverless-first architecture using AWS Lambda and Step Functions

Event-Driven & Distributed Systems

• Apply event-driven patterns using technologies such as Kafka, EventBridge and CDC
• Design idempotent and resilient distributed workflows
• Address data consistency, failure recovery and system behavior across interconnected services
• Implement performance controls including caching, pagination and rate limiting

Agentic Ecosystem Engineering

• Build governed API boundaries for AI agents using technologies including OpenAI, RAG and Gemini
• Ensure agents interact through approved APIs rather than unrestricted raw data access
• Support structured retrieval, provenance and deterministic fallback patterns
• Build security, governance and observability into agent interactions

API Lifecycle & Governance

• Own the API lifecycle from design and development through testing, documentation, versioning and deprecation
• Maintain backward compatibility and clear breaking-change policies
• Support CI/CD pipelines, observability and uptime requirements
• Manage infrastructure through Infrastructure as Code using Terraform and/or AWS CDK
• Partner with Security and Data teams on identity, authorization, privacy and consent requirements

🧩 WHAT YOU’LL HELP BUILD

Member & Relationship APIs

Identity, peer discovery, member relationships and graph-based data

Chapter APIs

Chapter operations, events and access

Agentic APIs

Governed API access and structured retrieval for AI agents

⚡ WHAT WE’RE LOOKING FOR

• 6–8+ years of backend/API engineering experience, with deep hands-on experience designing and building API layers for complex, production-scale systems
• Strong REST and/or GraphQL API design experience, including contracts, versioning and lifecycle management
• Experience designing APIs over complex or highly connected data models , including graph-based or relationship-driven data
• Strong understanding of non-functional requirements at the API layer , including scalability, reliability, resilience, latency, security and observability
• Experience solving caching, data consistency, concurrency and performance challenges in distributed systems
• Ability to evaluate architectural tradeoffs and translate business and product requirements into maintainable technical solutions
• Experience with AWS API Gateway and serverle…
