About Optibrium
Optibrium develops cutting-edge drug discovery software and AI solutions to complement the way chemists work. Our mission is to create a comprehensive platform, underpinned by novel technologies that supports intuitive and collaborative drug discovery without the steep learning curve.
We make molecular design, optimisation, and analysis faster, more efficient and more productive, by making computational techniques truly accessible and intuitive to medicinal chemists. It frees chemists to work more instinctively and confidently, while driving collaboration between disciplines, and helping ideas get developed, captured and shared faster.
Following a multi-million-pound financing package from Shawbrook Bank in July 2025, the company is entering a new phase of growth focused on strengthening its go-to-market engine, and expanding its presence across both large and top segments.
About the Role
We’re looking for a commercially minded Head of Marketing to lead the development of a scalable, measurable marketing engine that drives mid-market and enterprise pipeline growth, supports customer expansion and retention, and drives revenue operations, reporting, and attribution.
This is a hands-on role for a senior B2B marketer who’s as comfortable shaping strategy as they are rolling up their sleeves to deliver in a entrepreneurial environment. You’ll work closely with the wider Commercial team to keep everything aligned to our growth goals.
You’ll own a clear pipeline and revenue contribution target and be a key member of the revenue leadership team responsible for overall company performance. You’ll also lead a small team across content, demand generation, and product marketing, with the opportunity to develop and shape the function as the business scales.
