• Design the agentic platform used by other teams, including orchestration, tool registration and permissioning, durable state and memory, sandboxing, and trace‑level observability.
• Build agent workflows with multi‑step reasoning, tool use, human‑in‑the‑loop checkpoints, and recovery from partial failure during long‑running execution.
• Evaluate developments in model capabilities, agent‑design patterns, and evaluation practices, and translate them into platform architecture.
• Design retrieval‑augmented generation systems with hybrid search over legal corpora and citation grounding to specific sources.
• Build evaluation infrastructure, including golden datasets, regression harnesses, and offline and online evaluation loops.
• Establish model‑operations practices for routing, latency and cost budgets, prompt and context versioning, caching, and production reliability.

• Strong system‑design and architecture experience, including production of technical design documents.
• Excellent written and verbal communication, including the ability to work effectively with non‑technical domain experts and stakeholders.
• Demonstrated proficiency using AI tools in software development.

• Experience with fine‑tuning, model adaptation, or systematic evaluation across model families.
• Experience with large‑scale data pipelines or document‑processing systems.
• Experience with multi‑tenant SaaS architectures and data‑isolation requirements.
