The problem isn't ideas. It's execution.
Ecommerce development rarely breaks because teams are not working hard enough. It breaks when delivery lacks structure, priorities shift constantly and no one owns how engineering effort turns into shipped outcomes.
The Fractional Ecommerce Head of Development Service from Cogent2 provides senior, part time engineering leadership for ecommerce-led businesses that need stronger control over development delivery without hiring permanently. This role focuses on how ecommerce development is planned, executed and improved across the full lifecycle, not on high-level platform strategy.
It is designed for ecommerce brands with developers, agencies or distributed teams in place, but without a senior engineering leader to bring focus, delivery discipline and consistency.
Cogent2’s Fractional Ecommerce Heads of Development operate inside the business, leading teams day to day. Alongside leadership, you gain access to a joined-up technical and integration team that can support execution and refinement when required.

This service is particularly well suited to ecommerce businesses that:
- Rely heavily on custom development or ongoing platform changes
