📋 Description

• Design and build core platform primitives including provider abstraction layers (OpenAI, Anthropic, Google), structured output validation, streaming infrastructure, and token management systems • Own safety and compliance infrastructure including composable guardrail systems, PII detection/redaction, audit logging, and privacy-first observability that never leaks sensitive data to third parties • Build evaluation infrastructure that enables systematic quality measurement for non-deterministic LLM outputs—datasets, scorers (exact match, LLM-as-judge, schema validation), CI/CD integration, and regression detection • Lead churn containment strategy—design provider adapters and SDK architecture that absorbs rapidly-changing LLM provider SDKs without breaking consuming applications • Architect prompt lifecycle management systems including version control, Langfuse integration, GitHub-based review workflows, and deployment pipelines • Design Agent-as-a-Service infrastructure for long-running async tasks using AWS EventBridge, DynamoDB, and PostgreSQL • Collaborate with consuming teams to understand their needs, onboard them to the platform, and provide technical support • Influence architecture, technology selections, and engineering standards across the broader organization • Create reference implementations and technical documentation that enables other engineers to successfully adopt the platform • Champion quality engineering practices including comprehensive testing, type safety, and observability

🎯 Requirements

• 8+ years of software engineering experience with significant time spent building platform infrastructure, developer tools, SDKs, or distributed Systems • Production experience with LLM/AI systems—you've built and operated systems using OpenAI, Anthropic, or similar providers, and understand the unique challenges (token limits, non-determinism, provider outages, model deprecations) • Strong TypeScript expertise—this is our company standard, and you'll be designing APIs that other TypeScript developers consume • Experience designing APIs and abstractions that other engineers love to use—you understand the balance between power and simplicity • Understanding of safety and compliance in AI systems—PII handling, guardrails, audit logging, and responsible AI practices • Experience with event-driven architectures and async processing patterns (EventBridge, SQS, or similar) • Understanding of observability and monitoring for distributed systems—metrics, tracing, alerting, and debugging production issues • Strong communication and technical writing skills—ability to document systems clearly and work with internal customers across multiple teams • Track record of technical leadership without or without formal management—influencing architecture, mentoring engineers, and driving technical decisions • Experience with cloud infrastructure (AWS preferred: Fargate, DynamoDB, RDS, S3, EventBridge)
