The Role: How you'll make an impact at Personio
As Senior Engagement Manager for Professional Services, you'll lead the DACH pre-sales services motion—helping Sales and customers land on the right implementation approach before contract signature. You'll scope requirements, recommend the right services package, estimate effort, and shape Statements of Work that are both commercially sound and deliverable. Just as critically, you'll make implementation feel concrete and credible to customers who haven't lived it yet, walking them through what happens after signature, stage by stage, so deals close on real understanding rather than sales-brochure assurance.
 
This is hands-on work: leading complex scoping conversations, joining customer calls, and coordinating specialist input from Team Leads and delivery experts. You'll also help scale the model—turning repeat questions into standard guidance—by partnering with PS Operations on intake, reporting, and self-service infrastructure.
 
Success means Sales gets fast, credible, commercially sound support on complex deals; customers get an accurate picture of what implementation involves; and PS spends less time on requests that shouldn't need an Engagement Manager at all.
 
 
Role Responsibilities: What you'll do
Own complex Professional Services requests from DACH Sales end-to-end - leading discovery and scoping workshops, translating customer requirements into a clear implementation approach, and recommending the right services package, delivery model and level of support.

Define scope, assumptions, exclusions, timelines, effort and delivery roles; draft, review and approve Statements of Work for complex and non-standard engagements, ensuring recommendations are commercially credible and operationally deliverable.

Walk customers through what implementation will actually look like once they sign - phases, timelines, roles on both sides, and what's expected of them - giving Sales a credible, detailed narrative to de-risk the buying decision rather than a generic sales-brochure description.

Proactively surface and address the questions that create hesitation or stall deals (go-live timing, data migration, integration complexity, resourcing asks), and support Sales directly in explaining the approach and customer responsibilities.

Ensure what's explained pre-sale matches what delivery actually does post-sale, with a clear, documented handover into the delivery team, and review post-sale scope issues to identify weaknesses in the pre-sale process.

Identify implementation risks, dependencies and capability gaps before signature, coordinating input from Team Leads and implementation specialists and consolidating it into a single recommendation for Sales and the customer.

Estimate effort, duration and role mix for complex engagements, applying pricing, packaging and margin guardrails, and supporting discount or commercial exception discussions within agreed authority.

Balance customer requirements against standardisation, delivery capacity and long-term customer success, escalating material delivery, margin or capability risks, and partnering with Finance, Operations and PS leadership on approvals or exceptions as needed.

Identify recurring questions and scoping patterns that should become standard guidance, defining content for playbooks, decision trees, templates and effort calculators.

Partner with PS Operations to turn repeated answers into reusable Sales enablement, and coach Sales teams on services packaging, qualification,
