About the Role
ENSEK is transforming its core SaaS platform and shifting from a tightly coupled, monolithic environment into a modern, domain‑driven, product‑led engineering organisation. We’re hiring a Head of Engineering to help lead this evolution through shaping technical direction, strengthening engineering culture, and building a high‑performing, domain‑aligned organisation.
You’ll lead ~50–60 engineers across multiple squads, take full ownership of engineering outcomes, and drive meaningful change across ways of working, quality, delivery and leadership. This is a senior, strategic engineering leadership role — not a delivery manager position.
Key Responsibilities
* Build, lead and scale high‑performing teams, establishing strong leadership layers and fostering autonomy, accountability and modern engineering practices.
* Partner tightly with Product, driving shared ownership of outcomes, prioritisation and delivery.
* Lead platform modernisation, contributing to decoupling efforts, architectural direction, clear domain boundaries, communication patterns and scalability.
* Champion new ways of working, embedding shift‑left engineering, continuous improvement and modern delivery practices.
* Lift engineering standards, improving speed, quality, reliability and release processes.
* Shape culture and leadership, challenging legacy thinking and driving a high‑standards, product‑led engineering environment.
Key Outcomes
* Strong leadership in place across squads, improving autonomy, accountability and team performance.
* Noticeable improvements in delivery speed, quality and reliability.
* A cultural shift toward modern engineering principles and empowered, domain‑aligned product teams.
* Tangible progress decoupling the existing “small monolith” and establishing scalable, domain‑oriented architecture.
* Clear ownership and accountability embedded across engineering, with Product and Engineering aligned on priorities and outcomes.
Key Experience Needed
* Senior engineering leadership experience in SaaS or high‑growth scale‑up environments.
* Successful leadership of 40–60+ engineers through managers, leads and senior ICs.
* Proven experience modernising engineering organisations and driving cultural change.
* Strong partnership history with Product, delivering measurable outcomes and shaping shared strategy.
* Experience with platform evolution, decoupling/modernisation, and large‑scale technical transformation.
* Deep understanding of modern engineering practices (shift‑left, trunk‑based/CI‑first, high‑standards cultures, data‑informed decision‑making).
* Comfortable leading through ambiguity, challenging legacy models and establishing new ways of working.
Company benefits
* 25 days’ holiday + bank holidays
* Option to buy or sell 5 extra annual leave days per year
* Vitality Health Insurance, including private healthcare, virtual GP access and mental‑health support
* Pension with 5% matched contribution
* Regular team‑wide and company‑wide events
* 2 volunteering days per year
* Remote‑first working environment with offices in London and Nottingham
