# Head of Engineering-Founding Team Member
**Company:** [AI Fund](https://hotfix.jobs/companies/ai-fund)
**Location:** San Francisco, CA
**Skills:** TypeScript, Shopify, Mux, AI Tools, Cursor, Claude Code, CI/CD, Observability, Mobile Web, Embedded Widgets
**Posted:** 2026-01-08
> Lead engineering for early-stage commerce video platform, owning Shopify app development, AI-driven video workflows with Mux, and ensuring scalability across messy storefronts. Requires AI-native building, TypeScript proficiency, and end-to-end ownership.
## Job Description
## Responsibilities
- Own the codebase and technical direction: architecture, quality bar, shipping cadence, production reliability.
- Own and evolve a live Shopify app and storefront integration, hardening it across OS 2.0 and legacy theme realities with safe rollouts and easy rollback.
- Extend the mobile web creator upload flow with Mux: QR → prompt → record/upload → consent → submit.
- Turn content readiness from manual workflows into product: review/approve/publish, SKU mapping, internal tooling to automation.

## What Success Looks Like
- Onboarding new customers becomes boring and repeatable.
- Founder minutes per merchant drops materially because workflows are productized.
- Scale customers without bespoke engineering per store.

## Required Qualifications
- End-to-end production owner: design, ship, operate, and debug; close loops fast.
- Strong fundamentals: performance, reliability, security, and product/UX judgment (especially on conversion-sensitive surfaces).
- AI-native builder: ship production code with agentic tools (Cursor, Claude Code, Codex CLI, similar); use AI for speed, keep quality high with tests/CI/observability, debug AI output errors.
- Thrive in ambiguity and very small-team environment.
- **Ship primarily in TypeScript today, but prioritize fundamentals and AI-native approaches.**

## Nice to Haves
- Shopify apps/theme integration experience, or embedded widget/SDK experience in hostile third-party environments.
- Video pipeline familiarity (Mux or similar).
- Experimentation/analytics rigor: clean event design, integrity checks, debugging.
