Product Engineer

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.

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.

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.

Most companies hire engineers to execute a roadmap. At Twin, you'll help define it. Most engineers optimize existing systems. At Twin, you'll help invent new ones. Most jobs offer impact on a feature. This one offers impact on the future of the company.

"I wish I had joined earlier." This is one of those moments.
