Senior Account Manager

About the company

We’re partnering with a high-growth, global B2B SaaS company operating in the financial services and subscription-based industries. Their solutions are used by enterprise organisations across North America and EMEA to solve complex finance, accounting and commercial challenges.

They’re scaling quickly and investing heavily in their post-sales organisation. As part of this growth, they’re hiring two Senior Enterprise Account Managers to take full commercial ownership of strategic enterprise accounts in North America.

The role:

As a Senior Enterprise Account Manager you will own a portfolio of 10–15 strategic clients (c. $5m ARR), with full responsibility for retention, expansion and long-term growth.

This is not a “farmer CSM” role. You’ll operate as an enterprise account owner: leading executive relationships, negotiating renewals and expansions end-to-end, and proactively identifying whitespace across parent companies, subsidiaries and sister organisations.

You’ll report into the senior Client Success leadership team and work closely with Product, Sales and Professional Services, but you remain accountable for the commercial outcomes within your book of business.

Key responsibilities:

• Commercial ownership of a defined enterprise portfolio (c. 10–15 accounts, ~$5m ARR).
• Deliver against annual revenue targets (renewals expansion) across your portfolio.
• Independently negotiate and close renewals and expansions, including multi-year and enterprise-wide contracts – without relying on an AE to lead.
• Drive upsell and cross-sell across the full solution suite, mapping whitespace and expanding into parent companies, subsidiaries and sister organisations.
• Lead C-suite level engagements (CFO, Finance, Revenue, Technology leaders), delivering ROI-focused QBRs and positioning the company as a strategic growth partner.
• Build and execute account expansion plans that directly link product adoption and usage to commercial outcomes and value realisation.
• Accurately forecast pipeline, maintaining ≥90% forecasting accuracy on renewals and expansion opportunities.
• Partner with internal teams (Product, Sales, Professional Services, Finance) to resolve issues, drive adoption and unlock new value for clients.
• Act as a trusted advisor to senior customer stakeholders, challenging their thinking and bringing data-driven insights to every interaction.

Success metrics:

• Revenue Retention: ≥95% GRR across your portfolio
• Expansion: ≥10% annual uplift across your portfolio
• Executive Engagement: 2 C-level meetings per strategic account per quarter

About you:

• 5-10 years’ experience in enterprise SaaS Customer Success / Account Management / Account Director roles.
• Proven track record of owning and closing renewals and expansions end-to-end – not just supporting Sales.
• Experience managing a small portfolio of large, complex enterprise accounts (not a high-volume book of 50 accounts).
• Demonstrable success expanding into new entities – parent / sister companies, new business units or regions.
• Consistent history of hitting or exceeding commercial targets (renewals, upsells, multi-year expansions).
• Exceptional executive presence and confidence engaging and influencing C-level stakeholders.
• Strong commercial and financial acumen, able to link product adoption directly to business outcomes and ROI.
• Comfortable operating in a fast-paced, high-growth environment where not everything is fully defined and you’re expected to work independently.
• High energy, naturally relationship-driven and personable – able to quickly build rapport and trust internally and externally.
• Background in finance, accounting, fintech or consulting is highly advantageous, but not essential if you bring the right enterprise SaaS and stakeholder depth.

Location & ways of working:

• One role is Boston-based hybrid: expected in the office 2 days per week (Wednesdays one other day).
• The second role can be remote within Eastern or Central time zones (with periodic travel to clients and company offices).
• Both roles require regular travel within North America and occasional international travel for client meetings and internal events.

Compensation & benefits:

• Competitive base salary
• Uncapped variable compensation aligned to portfolio performance.
• 401(k) with employer match.
• Comprehensive medical, dental and vision coverage.
• Life and disability insurance.
• Pre-tax savings accounts.
• Employee share purchase plan.
• Generous paid time off and flexible, hybrid working environment.
