Twing.AI | AI/Full-Stack Engineer & Forward Deployed Engineer | Remote (US-friendly timezones) or NYC | Full-time or Part-time

We’re a lean (4 people, 3 of which are engineers), bootstrapped team building a private-equity automation platform (deal analysis, document processing, chat, investment theme research). Shipping fast, learning daily, and looking for hands-on engineers who want outsized impact.

- Stack: React Router 7/React 19, shadcn/Tailwind v4, Node/TypeScript (strict), PostgreSQL + Prisma + pgvector, S3; AI workflows with embeddings & LLMs.

- Why join: small team with direct ownership of core product, zero bureaucracy, Greenfield decisions and ability to learn extremely quickly, you’ll ship to paying users weekly.

AI / Full-Stack Engineer

- Own features end-to-end: data ingestion → AI pipelines → UI. - Design and tune LLM/embedding flows; keep latency/cost in check. - Requirements: strong TypeScript/Node, modern React, SQL + data modeling; comfort evaluating/using AI models; bias to ship.

Forward Deployed Engineer

- Work directly with customers (PE analysts/partners) to turn messy workflows into productized features. - Rapidly prototype, measure impact, harden for production. - Requirements: full-stack chops, great product sense, calm under ambiguity, willing to jump between code, data, and customer calls.

Happy to also talk to the self-taught. We care more about ability than credentials and value slope over intercept.

How to apply: Email jobs@twing.ai with “HN – [Role]” in the subject, a short note on something you’ve shipped, and any links (GitHub/portfolio). No recruiters.

Onlook (https://www.onlook.com/) | Founding Engineer (Fullstack / AI) | San Francisco or REMOTE (US) | Full-time

Onlook is an AI-native visual editor that lets designers, PMS, and engineers collaborate directly in the browser. We launched earlier this year, hit #1 on Hacker News, became the #1 trending repo on GitHub (above DeepSeek + Anthropic), and have grown to 22,000+ stars. We’re now hiring our first Founding Engineer.

We’re a design-led, product-obsessed team backed by YC, and we’re building a next-generation visual IDE used by tens of thousands of designers and engineers.

What we’re looking for:

• Full-stack engineer comfortable owning large, ambiguous problems

• Strong bias toward building fast and shipping often

• High craft, strong opinions, and willingness to defend them

• Desire to build an open-source product in public

• Someone who wants to help shape the culture, architecture, and direction from day one

Tech: Next.js, Tailwind, tRPC, Supabase, Drizzle, Bun, Docker, Anthropic, AI SDK.

What you’ll do: You’ll work across the stack, contribute to one of the fastest-growing OSS projects ever backed by YC, design and ship core parts of the visual editor, work with 100+ contributors, and help define the product with real users. If you’re in SF, we have a beautiful office near South Park.

How to stand out: Share something you’ve built. A project, repo, or portfolio tells us more than a resume.
