• Knowledge of RALPH Loops and their deployment.
• Proven ability to ship multiple large features per week by rebuilding workflows around agentic tools.
• Experience building backend AI orchestration layers that run autonomously.
• Proficiency in thinking in graphs (shared state, nodes, conditional edges, interrupts, circuit breakers).
• Experience shipping non-trivial agentic pipelines using LangGraph, Temporal, or equivalent.
• Experience with durable execution, structured outputs, human-in-the-loop checkpoints, and provider-agnostic model routing as baseline design constraints.
• Experience building evaluation harnesses, annotated datasets, and versioned prompt chains.
• Deep experience with Angular, Firestore, Observables, RxJS, and TypeScript.
• Experience with state management, component boundaries, reactive patterns, accessibility, and design systems.
• Ability to critically evaluate code quality, catch subtle errors, and provide feedback to improve work.

• Experience handling sensitive and/or confidential data, particularly in an education context (COPPA, CIPA, FERPA, PPRA, SOC 2).

Responsibilities

• Ship multiple substantial features per week, leveraging AI and agentic coding for rapid development.
• Operate as the technical lead and steward of the agentic coding pipeline, writing detailed prompts, specifications, and composing orchestrator agents.
• Build the AI workflow engine, developing graph-based agentic orchestration workflows with nodes, conditional edges, interrupts, and human-in-the-loop circuit breakers.
• Implement durable execution for long-running work that survives process restarts, rate limits, and outages, including an evaluation harness, versioned prompt chains, annotated datasets, and cross-provider benchmarks.
• Design and build user-facing features in Angular, Firestore, Observables, RxJS, and TypeScript, ensuring accessibility, performance, and responsive UX.
• Extend the context layer by contributing to living production artifacts like AGENTS.md and DESIGN.md.
• Collaborate with the Head of Engineering, Chief Innovation Officer, and other product leaders on technical direction, feature roadmap, and design decisions.
• Review the work of teammates and contractors, and collaborate on architecture and implementation reviews.
• Write PR comments, design docs, and agent skills to improve team efficiency.
