Product Engineer

Product Engineer

€110K–€160K base salary + Equity

Fully Remote | Lisbon, London and Berlin

A fast-growing AI startup founded in 2025 that's raised nearly $50 million in its first year and is already working with major enterprise customers.

The company builds AI agents that automate complex business processes. These agents work across existing software, spreadsheets and business systems, completing tasks that would otherwise take people hours.

You'll join a small, experienced engineering team where you'll have the freedom to make decisions, solve difficult problems and help shape the product as the company grows.

About the role

• You'll work directly with customers to understand their problems and build software that solves them.

• You'll take ownership of the full process, from understanding what needs to be built through to designing, developing, testing and releasing the product.

• The team uses AI throughout software development, including Claude Code, Codex, spec-driven development, parallel coding agents and automated testing.

• The aim is to spend less time writing code manually and more time making good product and engineering decisions.

• You'll work in a small team where engineers share ideas, review each other's work and take responsibility for what they build.

What we're looking for

• Full-stack experience. You should be comfortable building software across the frontend and backend.
• AI-native development. You already use tools like Claude Code, Codex or Cursor regularly and understand how to use coding agents effectively.
• Product ownership. You have experience taking products or features from an initial idea through to production.
• Customer understanding. You can work directly with customers, understand their problems and make sensible decisions about what to build.
• AI experience. You've worked on AI products or have a good understanding of how AI agents and LLM applications work.
• Engineering quality. You understand architecture, testing, code reviews and how to build reliable software.

Experience working in a successful autonomous startup or small engineering team would be a strong advantage.

Technology

The main stack is TypeScript, React, Next.js, Node.js and GCP.

You don't need any experience with the technology listed. Strong software engineering skills and the ability to learn new tools are more important.

What you can expect

• €110K–€160K base salary plus equity.
• Fully remote working with no mandatory office days.
• A small, experienced engineering team with a flat structure.
• Direct involvement with customers and product decisions.
• The opportunity to build production AI agents and help shape how the engineering team works.

You must be based in Lisbon, London or Berlin as they have offices here.
