Responsibilities

  • Run instrumented spikes and benchmarks for emerging LLMs, agentic systems, vector databases, orchestration frameworks, copilots, and assistants.
  • Design and maintain evaluation datasets, prompts, scenarios, telemetry, regression tracking, and benchmarking tools.
  • Build focused prototypes to assess architecture, integration patterns, operational constraints, security boundaries, and failure modes.
  • Produce decision memos and readiness guidance covering adoption recommendations, guardrails, limitations, operational considerations, and integration requirements.
  • Coordinate hand-offs of validated technologies to production engineering teams and support transitions when evaluation context is needed.
  • Work with Security, Legal, Compliance, and AI teams on risk assessments, mitigations, governance recommendations, reusable standards, and checklists.
  • Mentor engineers, participate in technical hiring, and share evaluation and experimentation knowledge through write-ups, talks, and meetups.

  • Experience with observability, telemetry, testing, benchmarking, distributed components, asynchronous workflows, reliability, and scalability.
  • Track record of designing experiments and benchmarks that compare AI models and tools under real-world constraints.
  • Experience constructing evaluation datasets, including task selection, labeling, holdout discipline, and maintenance as models improve.
  • Working knowledge of LLM-as-judge methods, human evaluation, inter-annotator agreement, statistical significance, regression tracking, telemetry, and versioning.
  • Ability to turn ambiguous ideas into scoped evaluation plans, make trade-off decisions, write concise decision memos, and explain technical results to non-specialists.
  • Experience collaborating with platform, product, and operations teams and influencing stakeholders without formal authority.
  • Curiosity, disciplined measurement, risk awareness, self-direction, and a preference for reusable tools, templates, and playbooks.

Benefits
