Head of Engineering | CTO @ VC backed company XAnge

🎯 Architecture · Tech leadership · Engineering culture

ℹ️ This is not a job posting for one specific company. XAnge is a VC firm: we keep a curated pool of senior profiles and introduce them to our portfolio startups when the right role opens up. This page describes what a CTO role typically looks like across our portfolio.

Work at an XAnge portfolio startup

You would join one of XAnge’s 80+ portfolio companies: fast-growing European tech startups building meaningful products across B2B SaaS, Healthtech, Fintech, Climatetech, Deeptech and beyond. These are scale-ups where the product and its architecture are the core of the company, with small, ambitious teams where ownership is real, decisions are fast, and your impact is visible from day one. Every company in the pool is backed by XAnge (Siparex Group) and surrounded by a community of 80+ founders and operators to lean on.

The team and why we need you

As CTO, you typically join a founder-led company that needs to turn an early product into a robust, scalable platform and build the engineering organization around it. You might step in as the first senior tech leader or succeed a technical co-founder. You own technology and engineering, report directly to the CEO/founders, and partner closely with Product and the business.

Why we need you: at this stage, technical choices and team quality set the ceiling on how fast the company can grow.

Your goals as CTO

Your mission is to build the technology and the team that can scale with the company. Typically, you will:

1. Own the technical vision and architecture, balancing speed of delivery with scalability and technical debt.

2. Build, structure and grow the engineering team through hypergrowth.

3. Put modern engineering practices in place (CI/CD, DevOps, code review, agile) and a strong engineering culture.

4. Partner with Product and the board to ship the roadmap and represent tech to investors.
