Descrição

• Own agent quality end-to-end: diagnosis, improvement, and validation across SmartAssist's orchestrator and subagents • Identify failure modes across quality dimensions factual accuracy, completeness, tone, actionability, and latency and prioritize what to fix • Drive quality improvements through prompt engineering, context engineering, and RAG retrieval tuning • Extend and mature our evaluation framework: scorers, golden datasets, regression gates, and online evaluation for production traffic • Close the feedback loop ensure that every change has a measurable, attributable quality signal • Collaborate with our Agent Architecture lead to distinguish quality problems that require prompt/context solutions from those that require structural fixes • Establish repeatable methodology that scales beyond any single agent or subagent

🎯 Requisitos

• 8+ years of software engineering experience, with at least 2 years working directly with LLMs in production • Deep, hands-on experience with prompt engineering and context engineering, you understand how model behavior changes with framing, structure, and input design • Strong working knowledge of RAG architectures: chunking strategies, embedding models, retrieval evaluation, and failure diagnosis • Experience building or extending LLM evaluation frameworks, you have designed scorers, worked with golden datasets, and thought carefully about what good looks like • Fluency in agent system design, you don't need to own the architecture, but you can engage as a peer on architectural tradeoffs that affect quality • Strong Python skills; comfortable working in data-heavy environments (Databricks, Delta tables, or equivalent) • Ability to communicate complex quality findings (written and verbal) to both technical and non-technical stakeholders, you can explain what’s broke, why it matters, and what needs to happen next without losing the room • Strong cross-functional judgment, you know when to escalate, when to resolve independently, and how to build credibility across engineering, product, and AI platform teams • A bias for clarity in ambiguous situations, when failure modes are murky and trade-offs are real, you bring structure and a clear point of view rather than waiting for consensus • Legally eligible to work in the U.S. on an ongoing basis • BS or MS in Computer Science, a related field, or equivalent industry experience.
