Job Description

We are seeking a Senior Partner Manager to build, scale, and operationalize high-impact strategic partnerships that drive product innovation, dynamic co-marketing, and building pipeline, revenue, and product adoption.

This role is ideal for a commercially minded partnerships leader who thrives at the intersection of strategy, go-to-market execution, and cross-functional leadership. You will own a select portfolio of strategic technology ecosystem partners, penetrating partner org charts, developing joint value propositions, enabling field teams, and generating measurable business outcomes.

This is not a channel operations role. Success is defined by partner influence, innovative partner campaigns, deal acceleration, and long-term partner leverage.

Key Responsibilities

Strategic Partner Ownership

  • Own a defined set of strategic partners

  • Develop joint business plans with clear pipeline targets (and revenue goals), well-defined GTM motions, and partner executive sponsorship

  • Serve as the primary point of accountability for portfolio partner success

Go-To-Market & Revenue Impact

  • Deeply contemplate partner thesis, objectives, and incentives and match to our own

  • Drive partner-sourced and partner-influenced pipeline through joint selling, co-marketing, and account alignment

  • Work closely with Sales to:

    • Identify priority accounts to engage partners

    • Support deal strategy and positioning

    • Remove friction in complex, multi-party deals

  • Enable sales teams with partner messaging, playbooks, and competitive context

Cross-Functional Leadership

  • Partner with Product and Engineering to influence:

    • Integrations

    • Roadmap alignment

    • Partner-driven feature requirements

  • Collaborate with Marketing on:

    • Launches

    • Field enablement

    • Partner campaigns and events

  • Align with Finance and RevOps on forecasting, attribution, and reporting

Executive & Partner Engagement

  • Build trusted relationships with partner executives and internal senior leadership

  • Represent the company in executive briefings, partner QBRs, and industry events

  • Communicate market trends, partner feedback, and competitive insights to the business

Operational Excellence

  • Establish clear success metrics (pipeline, revenue, adoption, partner health)

  • Maintain structured partner cadences, reporting, and internal alignment

  • Identify gaps, risks, and opportunities early—and act decisively

Success Metrics (First 6-12 Months)

  • Active joint GTM motions with top partners

  • Meaningful growth in partner-sourced and partner-influenced pipeline

  • Increased sales confidence and adoption of partner plays

  • Strong executive relationships with priority partner executives

  • Clear, repeatable partner engagement model

Why Join Us

  • High-impact role with direct visibility to executive leadership

  • Opportunity to shape and scale a strategic partner ecosystem

  • Clear path for growth as the partnerships function expands

  • Work on complex, meaningful problems with strong market tailwinds

Qualifications

Experience

  • 5–9 years in partnerships, alliances, or enterprise business development

  • Proven experience in B2B software, SaaS, cloud, or platform companies

  • Demonstrated success working with:

    • Strategic partners

    • Hyperscalers or infrastructure providers

    • Other large ecosystem partners

  • Track record of driving pipeline or revenue, not just managing relationships

Skills & Attributes

  • Comfortable navigating complex, multi-stakeholder environments

  • Strong commercial instincts; understands how deals actually close

  • Executive presence with the ability to influence without authority

  • Highly structured, which enables adaptability in ambiguous situations

  • Clear communicator both internally and externally

  • Data-driven, process-oriented, and accountable
