Anthropic CI/CD GitHub LLM Next.js Observability OpenAI Python RAG React Salesforce TypeScript Vercel

Description

Design, build, and ship LLM-powered agents on real production data. You own evals, prompt engineering, and the model-selection calls that make pilots succeed or fail. What you'd ship Build production agents (LLM + tools + RAG) for client operations Write and own eval suites — your work outlives every model migration Drive vendor selection: Anthropic vs OpenAI vs open-source, by use case Pair with consulting on discovery; write the ADR before the code Must-haves 3+ years shipping AI in production (not just notebooks) Comfort across at least two of: Anthropic, OpenAI, Vertex, local models Strong Python or TypeScript; you've written evals from scratch Public writing or open source we can read Build the application layer around the agent — dashboards, integrations, auth, billing. You own the surface clients see and the infrastructure that keeps it up. What you'd ship Next.js / TypeScript / Postgres / Vercel — end to end Custom integrations with client tools (Salesforce, HubSpot, Zendesk, custom) Build internal tooling that makes the consulting + AI team faster Own observability, CI/CD, and the on-call rotation Must-haves 4+ years shipping full-stack at production scale Strong React + TypeScript; you reach for SSR / RSC by default Comfortable owning infra (Vercel, Postgres, queues, jobs) Pragmatic — you'll cut a feature to ship the deadline Own top-of-funnel: paid acquisition, lead-gen experiments, conversion, attribution. You run experiments end-to-end, from hypothesis to pipeline impact, with a real budget. What you'd ship Build and optimize paid acquisition (LinkedIn, Google, programmatic) Design and run experiments on hero, pricing, contact, apply Own attribution model + pipeline reporting from first touch to closed-won Tight loop with sales — every campaign tied to qualified meetings Must-haves 3+ years running paid acquisition for B2B SaaS or services You've owned a marketing budget ≥$30k/mo and can show the dashboard Fluent in attribution (UTM, dbt, GA4, or your own stack) Strong on conversion copy — you can ship the headline yourself Compound organic distribution through long-form, technical content and GEO/AI-search optimization. You own the pillar guide library, industry pages, and ranking strategy. What you'd ship Write or commission deep technical content on AI implementation Optimize for both Google and AI-answer engines (ChatGPT, Claude, Perplexity) Build and maintain a programmatic SEO surface (industries, services, use-cases) Pair with founders on thought leadership — long-form, signed pieces Must-haves Strong writing portfolio with technical depth (engineering-adjacent) You've moved a domain from <1k to 50k+ monthly organic visits Comfort in MDX, GitHub PRs, Next.js content — content as code Opinions on GEO/AI-search — and a track record on at least one site If you'd build something we'd be lucky to have — Voice Agent Engineer, Brand Designer, Founders' Office, Automation Engineer — make the case. We read every one. What you'd ship Tell us what role you'd carve out, and what you'd ship in the first 90 days Show us one thing you've actually built — production, not theory Be specific about how the role compounds with the existing team Must-haves A clear case for the role you're proposing Evidence you've shipped at this level somewhere before Comfortable being the first hire in your specialty
