We're looking for an experienced GTM Engineer to own Apollo's most strategic customer relationships. This is a rare blend of enterprise account strategist, AI-native systems builder, and trusted executive advisor — someone who can operate at the C-suite level as naturally as they can architect a signal-based outbound campaign. The GTM Engineer is Apollo's answer to the CSM: a success architect who designs and deploys customer interventions that drive adoption, credit consumption, and revenue growth.

On the Mid-Market team, you're not just managing accounts — you're navigating complex organizations, building relationships across multiple stakeholder layers, and ensuring that every buying persona from RevOps to the CRO is aligned on value.

What You'll Do

• Own customer outcomes post-sale: GRR (>95%), NRR, product adoption, and credit consumption growth across a portfolio of Apollo's highest-value accounts.
• Multithread across complex organizations: Build and maintain active relationships with 3+ stakeholders per account — spanning RevOps, Sales Leadership, Marketing, and the C-suite — to drive alignment on GTM strategy and expansion outcomes.
• Configure Apollo to power AI-driven workflows: ICP definition, signal-based sequencing, messaging architecture, and campaign design tailored to each account's unique GTM motion.
• Turn usage data into expansion: Use product telemetry and behavioral signals to identify and execute upsell, seat expansion, and credit consumption opportunities before customers ask for them.
• Advise executives on GTM strategy: Present credibly to VP- and C-level stakeholders, proving ROI with measurable lift and influencing how your accounts think about their entire go-to-market motion and tech stack.
• Protect and grow your book: Identify and mitigate churn risk early by ensuring your accounts are never single-threaded and value is visible across the organization.

Who You Are

• 6+ years in Solution Engineering, GTM consulting, Customer Success, RevOps, Growth, or Sales Development — with a clear track record of influencing complex, multi-stakeholder accounts.
• A natural multi-threader: You've successfully expanded relationships beyond a single champion inside enterprise accounts.
• AI-native: You're currently designing GTM campaigns, workflows, and systems agentically.
• Analytically fluent: You speak in signals, segments, and pipeline impact.
• Executive-ready: You present confidently to C-suite stakeholders, adapt your message to the audience, and can hold a strategic business conversation as easily as a technical one.
• Customer-obsessed: You build lasting relationships and raving fans.

Success Looks Like

• Retention >95% across your Mid-Market book.
• Consistent credit consumption uplift (10%+ NRR).
• Seat expansion and CSQL generation.
• Executive-level relationships maintained across every Mid-Market account.
