Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the Role Sentry's Revenue Operations team is built around three pillars — Analytics, GTM Technology, and Deal Desk — and we're hiring a Revenue Operations Manager who will work across all three. This isn't a role where you sit at the end of the sales process waiting for deals to land in your queue. We want someone who is curious about why deals are structured the way they are, who spots inefficiencies before anyone else does, and who sees our CPQ and Salesforce environment as a system to be improved, not just operated. Roughly half your time will be deal desk ownership while the other half is the broader rev ops surface area — process design, systems and tooling, reporting and insights, and the cross-functional projects that keep sales, finance, and marketing running off the same playbook. Across both, your mandate is the same: reduce friction, automate the routine, and make more of the work self-service for reps. This role is an opportunity to grow into a deep operator and systems thinker. If you're someone who thrives on bringing order to chaos, who gets excited about eliminating the manual step that shouldn't exist in the first place, this is the job. In This Role You Will Own Deal Desk - end-to-end processing of deals — including quote creation, discount review, order form generation, and approval routing — with minimal escalation and fast turnaround. Become an expert in our CPQ system and Salesforce integration– not just as a user, but as a critical voice for what should change. Document pain points, propose solutions, and work alongside our GTM Tech team to drive improvements. Help design and implement self-servi
