About the Opportunity:

The Services Engagement Manager (SEM) is the single accountable owner of scoped, time-bound professional services engagements — from the moment they’re shaped in the sales cycle, through delivery, formal acceptance, and clean financial closure. The role protects two things at once: our customers’ outcomes and our delivery integrity. Where a Customer Success Manager owns the open-ended ARR relationship and is measured on retention and growth, the SEM owns a discrete, funded engagement and is measured on margin, on-scope and on-time delivery, and a clean exit. This is a senior, highly cross-functional role at the intersection of sales, delivery, and customer success, reporting to the VP of Customer Success.

What You’ll Do:

• Shape and scope engagements with Sales. Translate customer requirements into a defensible Statement of Work — scope boundaries, assumptions, deliverables, acceptance criteria, effort estimates, and milestone/payment structure.

• Guard scope integrity before signature. Validate that what Sales is proposing can be delivered at target margin, identify what’s out of scope, and propose a change order before an engagement is signed.

• Own the engagement end to end. Drive the engagement plan, cadence, and milestone tracking from kickoff through delivery.

• Orchestrate delivery resources. Sequence and prioritize Forward Deployed Engineers, detection engineering, subject-matter experts, and third-party partners against the plan.

• Manage scope and margin in flight. Actively manage scope against the SOW, raise change orders for additions rather than absorbing silent creep, and run the engagement P&L — tracking burn against estimate and flagging overruns early.

• Drive to acceptance and clean closure. Secure formal customer sign-off against defined acceptance criteria and execute clean financial closure, including final milestone completion, invoicing readiness, and revenue-recognition support.

• Hand off and improve the catalog. Run a structured handoff to the Customer Success Manager for any steady-state relationship, and feed reusable scope and estimate patterns back into the services catalog.

What You Bring:

• Professional-services delivery or consulting experience in cybersecurity or enterprise software, with a track record of personally authoring SOWs, estimating effort, and owning a margin or utilization number.

• Strong scoping and effort-estimation skills, SOW authoring, and change-order discipline.

• Project and delivery management strength, including engagement P&L and margin management.

• Executive stakeholder management — credible in front of a CISO — plus enough SecOps / detection-engineering fluency to scope engagements and serve as a real check on what’s being sold.

• Comfortable being measured on delivery and margin outcomes over relationship longevity, with a bias toward closure and the ability to hold the scope line firmly and diplomatically.

Bonus Points:

• A delivery or project-management background paired with genuine technical depth.

• Experience working with partners on jointly owned engagements.

• Background in a high-growth startup or MDR / security-services environment.

Education & Certifications:

• Bachelor’s degree in Business, Computer Science, Information Systems, or a related field (or equivalent experience).

• Relevant certifications such as PMP, ITIL, Security+, or CISSP are a plus.

Why Join Us?

• Opportunity to own high-stakes professional services engagements end to end — from scoping through formal acceptance and clean closure — as the single accountable owner of customer outcomes and delivery integrity.

• Collaborate with a talented and innovative team focused on continuously improving security operations.

• Competitive salary and benefits package.

• A culture of growth and development, with opportunities to expand your knowledge in AI, cybersecurity, and emerging technologies.
