Responsibilities
Own 0→1 and 1→N features across the stack, from design docs to building high-throughput data pipelines and scalable FastAPI services
Architect and own the core agent orchestration engine, designing complex, multi‑agent LLM workflows (routing, tool‑use, memory, evaluation) with deterministic fallbacks, guardrails, and auditable actions required by enterprise users
Build AI‑native, human‑in‑the‑loop UIs. Craft React/Next.js interfaces that let users collaborate safely with agents, with transparency and explainability by design
Develop the "factory for the factory". Build our experimentation platform: CI/CD for prompts and agents, offline/online evals, drift detection, safety layers, and rollout controls
Ship fast, safely. You’ll instrument everything for reliability, write concise design docs, add robust tests, and build dashboards and alerts for features you launch
Partner cross‑functionally with Product, AI, Design, CS; talk to customers and SMEs, and turn ambiguous problems into shipped product
Obsess over performance, optimizing for latency across the system: caching, model selection, distillation, batching, vector search, and infrastructure efficiency (GPU/CPU)
Operate what you build. This includes on‑call ownership, leading incident response, and driving learning through blameless postmortems
Qualification
Required
Experience with LLM/agent systems, evals, and prompt tooling; RAG, embeddings, vector dbs
Deep knowledge of event‑driven systems, streaming, and workflow engines
Expertise in observability (OpenTelemetry/Prometheus/Datadog), feature flagging, or A/B platforms
Background in enterprise security and compliance (SOC 2, GDPR)
Bias to action: short specs, small PRs, daily deploys
In-person collaboration: we're building the NYC hub together; whiteboards > long threads
High ownership: you'll touch product, talk to customers, and influence the roadmap
