Role description
We are seeking a Fractional CTO to lead the strategic and technical direction of our SaaS client. This role is primarily focused on strategy, architecture, and leadership, while maintaining enough hands-on technical fluency to guide a team of six developers working with a modern AWS-based stack. Rate wise, this is outside IR35 and will involve weekly on-site visits to central Bristol.
The Fractional CTO will be responsible for getting the AI Platform live. From there, the focus will be ensuring scalability and security, and aligning technology decisions with business objectives. You will act as the bridge between executive leadership and engineering, ensuring the platform is delivered on time, within budget, and to enterprise-grade standards.
Key Responsibilities
• Define and execute the technology vision and roadmap for the Agentic AI SaaS platform.
• Provide thought leadership on AI-driven SaaS trends, agentic architectures, and B2B adoption.
• Lead, mentor, and inspire a team of 6 developers, fostering a culture of collaboration, innovation, and accountability.
• Guide the design and build of microservices behind API Gateway (REST/HTTP), running on Lambda and/or containerized workloads on EC2/Fargate.
