Build an AI-native company from the early days

One of Swiss Founders Fund’s fast-growing portfolio ventures is hiring a junior software engineer to join its founding engineering team.

The company is building an AI-native product and preparing its Y Combinator application. We are looking for someone who can help build and scale the product through its next stage: a strong engineer who learns quickly, works independently, and takes responsibility for getting things shipped.
“Junior” refers to your career stage. We still expect solid technical fundamentals, initiative, and evidence that you can build working software. Personal projects, open-source contributions, internships, freelance work, and previous startup experience all count.

What you’ll do

• Build and ship features for the core product, from understanding the problem through implementation, testing, and release.
• Develop APIs, backend services, database integrations, and user-facing functionality where needed.
• Integrate AI models and third-party services, and assess whether they work reliably in practice.




• Investigate bugs, improve performance, and help the product handle growing usage.
• Write clear, maintainable code and use tests where they meaningfully reduce risk.
• Work directly with the founders and engineering team to make practical technical decisions.
• Communicate progress, flag blockers early, and follow through without needing constant supervision.

What we’re looking for

• Evidence that you can build. You have created working software and can explain your contribution, technical choices, and what you would improve.
• Strong fundamentals. You understand APIs, databases, debugging, version control, and how the different parts of a web application fit together.
• Depth in at least one language or framework. You can do more than follow a tutorial and are comfortable learning the tools the product needs.
• Independent problem-solving. You can break down an unfamiliar problem, investigate opt
