Future - Applied AI Engineer
Requirements
• Strong Python skills: you've built and deployed services on large production systems. • Experience with LangChain/LangGraph or similar agent frameworks. • Hands-on experience with LLMs in production: prompt engineering, tool/function calling, structured output, evaluation. • Comfort with async Python, HTTP APIs, and streaming protocols (SSE, webhooks). • Experience with data validation and schema design (Pydantic, JSON Schema). • Ability to debug across layers: from a broken LLM tool call to a misconfigured Terraform resource. • Clear communication: you'll work directly with product, mobile, and backend engineers. • Familiarity with AWS (Bedrock, ECR, CloudFront, S3, Cognito) or other cloud agent hosting. • Observability and tracing tools (Langfuse, OpenTelemetry, Datadog). • Exposure to evaluation frameworks: LLM-as-a-judge, automated scoring, dataset management. • Infrastructure-as-code (Terraform, CDK).
Responsibilities
• Build and ship AI agents that serve real users: tool-calling LLM systems with structured output, parallel API orchestration, and streaming responses. • Design evaluation harnesses and quality scoring — we use Langfuse, rubrics to measure safety, effectiveness, and personalization. • Own the full loop: prototype a new agent capability, validate it with evals, deploy it to staging and production, monitor traces, and iterate. • Improve reliability, latency, and cost through prompt caching strategies, token budgets, retry logic, and observability. • Write the tools agents use: API integrations with Pydantic validation, exercise search over local databases, structured workout submission.
