Product Engineer

Founding Product Engineer
Build the Future of Autonomous Companies

At Twin, we're building a world where anyone can deploy AI agents capable of running real business operations.
Not chatbots.
Not copilots.
Autonomous agents that take actions, make decisions, execute workflows, and create value.
In just a few months, we've seen explosive adoption, thousands of users building businesses on top of Twin, and millions of agent actions executed.
We're still at the beginning.
We're looking for a Founding Product Engineer to help build the company that builds companies.

The Role
This is not a traditional software engineering role.
You won't receive tickets from a product manager.
You won't spend months discussing roadmaps.
You won't optimize a tiny corner of an existing system.
You'll work directly with founders, users, and other builders to design, build, and ship product every day.
You'll move across product, engineering, design, AI, infrastructure, and growth whenever needed.
One day you might:
Build a new agent capability from scratch

Design an onboarding flow that doubles activation

Improve infrastructure supporting millions of executions

Talk directly with power users

Ship a feature in the morning and iterate on feedback the same afternoon

Use AI to prototype something in hours that would previously have taken weeks

If that sounds exciting, keep reading.

Who We're Looking For
We're looking for builders.
People who create.
People who ship.
People who don't wait for permission.
You might be a fit if:
You've built products people actually use

You've launched startups, side projects, open-source projects, or meaningful products

You think about users as much as technology

You enjoy turning ideas into reality extremely quickly

You thrive in ambiguity

You naturally take ownership

You care about product quality

You love learning

AI-Native Engineering
We believe the best engineers of the next decade will not be those who type the fastest.
They will be those who can effectively direct, evaluate, and collaborate with AI.
AI coding assistants should already be part of your daily workflow.
Cursor.
Claude Code.
Codex.
Or whatever tools help you move faster.
You should be comfortable:
Pair-programming with AI

Generating and reviewing large amounts of AI-generated code

Using AI for debugging, prototyping, testing, and research

Building dramatically faster without compromising quality

Leveraging AI as a force multiplier

The question is no longer:
"Can you write the code?"
The question is:
"Can you use AI to build the right thing, verify it, and ship it?"

Strong Signals
These are not requirements, but they tend to correlate with success here:
Former founder

Early-stage startup experience

Open-source contributor

Exceptional side projects

Competitive programming background

Olympiad participant

Hacker mindset

Product obsession

Evidence of unusually fast learning

What We Value

Ownership
You see a problem, you solve it.
Speed
Fast iteration beats endless planning.
Judgment
Good decisions scale better than good code.
Ambition
We're building something that shouldn't be possible.
Craft
Fast doesn't mean sloppy.
