Well be reviewing your responses as part of the initial screening process. Please make sure to complete and submit all details through the form to be considered for the next stage.

What will you do

• Own the evaluation loop: Design offline and real-time test harnesses, golden-set datasets, and automated regression dashboards that grade each new agent release on precision, recall, latency, and cost.
• Harden safety and guardrails: Implement content filters, prompt firewalls, and fallback chains so answers stay compliant with SOC 2 and HIPAA constraints.
• Optimize prompts and retrieval: Iterate on system, user, and tool prompts for diverse enterprise workflows. Tune ranking models and vector search parameters to lift relevance.

• Benchmark LLM approaches: Compare open-weight models, hosted APIs, and fine-tuned derivatives. Present trade-off reports that balance performance with budget.
• Prototype and demo: Build thin, focused proof-of-concepts that show customers new capabilities before we commit to full sprint cycles.
• Document and share best practices: Write concise run-books, design notes, and post-mortems so the next engineer can reproduce your results without guesswork.
• Stay current: Track the latest research on retrieval-augmented generation, tool-calling agents, and evaluation methodologies; bring the most practical ideas into production.

What we look for

• Two to five years of building or operating machine learning or data-intensive back-ends in production.
• Strong work ethic and bias for ownership. You identify problems, propose fixes, and drive them to closure.
• Clear, systematic thinker. Your design docs read like thinking in public, and your code structure reflects first principles reasoning.
• Proficient Python engineer comfortable with type hints, pytest, and modern packaging.
• Hands-on experience with at least one of: LangChain, LangGraph, or other agent frameworks.
• Familiarity with vector databases and semantic search fundamentals.
• Evidence of structured problem solving: could be a design doc, a refactored subsystem, or an open-source pull request.
• You should be comfortable reading and implementing research ideas from scratch, such as those from
