CTO (Chief Technology Officer)
Valsoft · Remote
We are hiring a CTO for one of our UK software businesses: an established company with a long track record and a leading share of its market.
The business has deep customer loyalty and a hard technology problem. It runs a large, mission-critical on-premises estate and is developing a new cloud platform, and it now has the backing to rebuild for the next 20 years. This CTO will lead that rebuild.
This role has two modes. With the established team running the existing products, you lead through managers and team leads; daily production coding is not expected, but you must be able to review architecture and step in to steer major incidents. In the small, elite squad rebuilding the platform, you will be more hands-on.
You will own all technology in the business: product engineering, QA, DevOps and cloud, data, and infrastructure.
