Chief Technology Officer - B2B Software

We're working with a fast-scaling deep tech company building the infrastructure that lets humans and AI agents co-develop safety-critical software, auditable by construction, for industries where "move fast and break things" isn't an option.

The business today: 25 people, 17 enterprise customers, a genuinely strong open-source footprint, and a Series A targeted for mid-2027.

They're hiring a CTO to build the engineering organisation behind an entirely new category, not simply manage what already exists.

What you'll own:

• Long-term technical vision and technology strategy for the company
• Scaling the engineering team from ~15 to 30-50 engineers while protecting culture and quality
• Recruiting, mentoring and developing the next layer of technical leadership
• Staying years ahead of the market on AI trends, emerging technology and competitive threats
• Turning customer feedback into long-term product and technology direction, working closely with rollout and commercial teams
• Acting as a true strategic thought partner to the founders on company, product and technology direction
• Representing the company externally, at conferences, with customers, and within the developer community
• Balancing execution speed with the rigour safety-critical software demands

What they need from you:

• Track record of scaling an engineering org from roughly 10 to 50 engineers, or a comparable growth stage
• A builder's mindset, not a manager's. High ownership and accountability
• Strong technical credibility from respected startups or technology companies
• Experience setting engineering strategy inside a fast-growing B2B software business
• Comfort with ambiguity, hands-on when needed, genuinely excited to build from scratch
