About the job

Welcome to Moonlake, where we leverage AI to craft immersive world simulations.

Mission: Join us as an Applied AI Research Engineer focused on designing and coding intelligent agents (post-training and systems).

Scope of Work:

  • Design agentic systems: Develop tool catalogs, function calls, program synthesis, repair loops, and control mechanisms such as ReAct, Reflexion, ToT, and LangGraph, along with self-verification and sandboxed execution.
  • Evaluation mindset: Create comprehensive task suites for multi-step coding, including full-stack LLM engineering, prompt libraries, routing, retrieval, KV-cache management, streaming, and telemetry.
  • Security and isolation: Implement Docker/firejail, manage network egress controls, maintain secrets hygiene, and ensure dependency pinning for supply-chain integrity.
  • Strong post-training capabilities: Conduct supervised fine-tuning, preference and trace reinforcement learning (DPO/RLAIF/RLHF), dataset curation, reward shaping, and safety filtering.

Technical Signals:

  • Experience shipping agents that successfully navigate real repository test suites from start to finish.
  • Published research in the fields of agentic systems and code generation, contributing to frameworks or open-source evaluations such as LangGraph, AutoGen, Guidance, LEAP, and SWE-bench variants.
  • Developed datasets from execution traces, demonstrating significant enhancements from data over parameters.

We are committed to maintaining an on-site, collaborative team environment based in San Mateo.
