About Friends for Humanity

We're a venture-backed consumer company with a simple thesis: the people who understand young people best will win the most important product category of the next decade.

Our product is already in the hands of thousands of users. Retention is best-in-class. Our creator network drives millions of impressions monthly. And we're just getting started.

We're a small, sharp team based in NYC, no middle management, no committees, no waiting for permission. If you're good, you'll have an impact in your first week.

The Role

You'd be one of the earliest engineering hires. That means you're not joining a team, you're building it. You'll work directly with the CEO across the entire stack: product, infrastructure, AI, and everything in between. Nothing here is someone else's problem.

What you'll own

The full product stack, from frontend to backend to deployment
AI model layer including multi-model routing, context management, and inference optimization
Post-training and fine-tuning pipelines on proprietary conversational data
Real-time infrastructure built on Convex or similar

What we're looking for

Must haves:

Love to build for the love of the game
Up to date with current AI trends and models
Deep with TypeScript/Node and comfortable across the full stack
Experience with multi-model API architectures — routing, fallbacks, cost/quality tradeoffs
Exposure to fine-tuning, RLHF, or post-training workflows
You default to shipping, not debating. You fix what's broken before anyone asks
Able to communicate in English
Culturally aware / Doom Scroller

Nice to have:

Hungry to learn how a real startup operates
Experience building for or alongside creator/influencer networks
Comfortable working async across time zones
Experience in startups and software engineering
Have built in public, contribute to open source, or have side projects people can look at
Having efficient agent workflows to do coding tasks
Bachelor's or Master's in Computer Science

Compensation & Logistics

Full-time contractor role, working with a strong team of engineers and product people
Compensation: ₫13,156,000 – ₫78,936,000/month depending on experience. Equity negotiable.
Reporting directly to the CEO/Engineering team
