Senior AI Engineer

Position Summary We’re hiring a product-oriented Senior AI Engineer who loves tinkering with LLMs and shipping real agent systems. We spend less time on fine-tuning and more on orchestration, evaluation, and reliability—so agents do real work safely, quickly, and repeatedly. What we’re looking for - Agentic systems: Function/tool calling, multi-step planning, routing, memory, and retrieval. - Engineering first: You can wire up services, craft eval harnesses, and debug latency/cost at scale. - LLM breadth: Comfortable comparing models/hosts, prompt strategies, and guardrail techniques. - Product focus: You instrument outcomes, run A/Bs, and iterate to improve task success rates. - Opinionated: Deep level of understanding of the technological landscape, making both high level system and granular code design decisions based on understanding rather than preference - diving deep on unknown patterns in order to build the best product. Responsibilities - Design, build, and productionize agent workflows end-to-end (APIs, tools, evals, monitoring). - Create safety, cost, and latency controls; build dashboards and alerts for reliability. - Partner with product/design to invent new interaction patterns and ship them fast. - Document patterns and mentor engineers on best practices for LLM-powered features. Nice to have - Experience with workflow engines (e.g., Temporal), comfort in full stack engineering Logistics: - Compensation: $165K - $230K salary, $100K-200K equivalent in new hire equity (4 year vest) - Location: New York City. We are a fully in-office team working out of Midtown Manhattan Monday through Friday. We allow for WFH days when anyone is traveling, but we do not allow for permanent remote work. - Benefits: - Generous health, dental, and vision insurance - 401k with 3% automatic contribution (no vesting) - Paid Lunches - Wellness and Citi Bike benefit - Unlimited PTO
