200000 –250000 EUR / yearSeniorRemoteaiinfrastructureproduct development
Build and ship product features daily, working directly across product, engineering, design, AI, and infrastructure at an early-stage autonomous business platform.
Responsibilities
- 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.
Other
- 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.
- 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
- 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?"
- 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
- You see a problem, you solve it.
- Fast iteration beats endless planning.
- Good decisions scale better than good code.
- We're building something that shouldn't be possible.
- 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.
