About the Role
The Sales Executive is an early-career commercial role designed to develop future sales and account management talent organically within the Cellusys sales organisation.
This role is suited to a team-oriented individual with ambition, energy, and a strong willingness to learn, combined with a developing technical understanding of the Cellusys portfolio. Working closely with Senior Sales Team Members and Directors of Business Development, the Sales Executive supports the full sales and account lifecycle while progressively building the skills required to take ownership of customer accounts.
A key purpose of the role is to take responsibility for non-customer-facing and coordination activities across assigned accounts, enabling senior sales colleagues to focus their time on customer engagement, pricing strategy, expanding the customer base, and growing existing accounts.

As a Sales Executive, the role carries responsibility for the day-to-day coordination and organisation of assigned customer accounts, under the guidance of senior sales team members. This includes ensuring opportunities are tracked, internal inputs are aligned, and account-related activities are executed effectively, while progressively developing the capability to take fuller commercial ownership over time.
