• You'd be one of three engineers on a small senior team, working directly with me (CEO), rebuilding the whole experience around agents that work for the user. You'll ship to millions of people who'll tell you, immediately, whether your thing worked. • AI features end-to-end. You own the API, the model orchestration, the streaming UI, the evals, the rollout. Nothing gets thrown over a wall. • Agentic workflows. Multi-step agents that research roles, analyze careers, write bullets, prep interviews, negotiate offers. Real agents, not chatbots with retrieval bolted on. • Streaming interfaces that feel instant, handle retries gracefully, and degrade well when a model does something weird. • The eval system this team needs. Harnesses, regression suites, latency and cost budgets. The thing that lets the next ten engineers ship without vibes. • Prompt and feature iteration infra. The system that lets us A/B test a new prompt without shipping a release. • Time with users. Customer calls, support tickets, user interviews. You'll know who you're building for, by name.
