We’re hiring a Senior Applied AI Engineer to join a fast‑moving, high‑ownership team building next‑generation AI assistant and productivity capabilities. This role blends LLM product engineering, evaluation science, hillclimbing, and internal tool building with the pace and creativity of a startup. You’ll work across the entire lifecycle of features from early prototypes to production‑grade systems and help define how millions of users interact with AI.
Job Responsibility:
Design and ship LLM‑powered assistant features, including conversational flows, agentic behaviors, retrieval pipelines, and multimodal interactions
Build prompt architectures, system instructions, and orchestration logic that ensure reliability, grounding, and personality consistency
Prototype new capabilities rapidly and iterate based on user signals and evaluation data
Build and maintain evaluation frameworks for correctness, safety, grounding, and UX quality
Run hillclimbing loops across prompts, models, and tool‑use strategies to continuously improve assistant performance
Analyze failure modes, design mitigations, and drive systematic improvements across the stack
Develop internal tools for prompt experimentation, model comparison telemetry and debugging automated eval pipelines
Create reusable frameworks that accelerate the entire AI org’s ability to ship high‑quality assistant features
Integrate LLMs with product surfaces, APIs, and backend systems
Build lightweight ML components (ranking, classification, summarization, personalization) that enhance assistant intelligence
Collaborate with PM, design, and research to turn ambiguous ideas into polished user experiences
Operate with startup‑founder energy: bias for action, rapid iteration, and comfort with ambiguity
Work closely with researchers, engineers, and product leaders in a fast‑moving AI team where ideas ship quickly and impact is immediate
Contribute to a culture of experimentation, clarity, and high‑quality execution
