• Build and execute strategic account expansion plans that directly tie product adoption to commercial outcomes.
• Accurately forecast pipeline and deliver ≥90% forecasting accuracy on renewals and expansions.

If you’re interested in working at Aptitude, but don’t feel you meet every single requirement of the role, we’d still like to hear from you! A diverse workforce is an essential part of our culture, and we’re dedicated to ensuring that our staff can show up as their authentic self – safe in the knowledge that their differences will be embraced and respected by all. We’re strong advocates of supporting applicants from a wide variety of backgrounds which include different ages, genders, ethnicities, physical abilities and sexual orientation, and we work hard to build the confidence of our workforce through inclusivity, equity and ongoing training. So, if you’re excited about this role but your past experience doesn’t align perfectly with every requirement, we’d encourage you to apply anyway. You might be just the candidate we’ve been looking for, whether it’s for this role or another.

What we're looking for

• 10+ years’ experience in enterprise SaaS Customer Success or Account Management roles.
• Proven track record of closing renewals and expansions independently – not reliant on Sales.
• Demonstrable success in expanding accounts into parent/sister companies and new business units.
• Consistent history of achieving or exceeding commercial targets (renewals, upsells, multi-year expansions).
• Exceptional executive presence and confidence influencing C-level stakeholders.
• Deep commercial acumen with the ability to link product adoption directly to business outcomes and ROI.
