Our Purpose At SentinelOne, we are driven by a clear purpose: to give the advantage to those who secure our future.

If you are motivated by meaningful challenges and want your impact to be real, measurable, and global, you will find purpose here.

Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes. As a Partner Development Manager on SentinelOne's Global MSSP Ecosystem team, you'll own account management, partner enablement, and partnership support for a defined, named set of MSSP Ecosystem partners — that sell through MSSPs. Unlike the regionally-aligned Partner Development Manager role, your book of business is fixed by name rather than territory, and you'll report into the Director, Global MSSP Ecosystem Sales. You'll design high-quality, strategic service activation plans for each named partner, growing wallet share and reducing churn within an existing, high-value book rather than recruiting net-new logos. You'll work closely with Sales Engineering, Professional Services, Customer Success, Marketing, and Support to design and implement joint go-to-market campaigns, develop strategic business plans, and run a disciplined account planning cadence aligned to MEDDPICC. Ideal candidates bring prior experience selling full-stack security solutions, expanding product footprint within a fixed set of strategic accounts, executing strategic business plans, and outperforming the market — with a background in high-tech sales and prior experience selling to Service Providers and/or Managed Security Service Providers, ideally including exposure to platform-commit or similarly concentrated partner relationships. This role requires moderate travel (typically 25–50%) to build and sustain in-person relationships with your named partners. What Will You Do? - Own and grow a fixed, named portfolio of between 3-10 MSSP Ecosystem partners, serving as the primary business owner of each relationship and building revenue-generating security service offerings with each. - Develop and execute a strategic business plan for each named partner to manage innovation, collaboration, and the next logical areas for business expansion within the partnership. - Establish and maintain senior relationships within your named partners, nurturing partner executives and key sales leaders to align priorities across respective field organizations and build a “better together” fly-wheel that holds up against competitive threats. - Drive new pipeline and revenue through each partner's marketplace or distribution motion, using data to sharpen strategy and tactics and establish competitive advantage for SentinelOne's established and emerging product portfolio. - Stay current on the SentinelOne competitive landscape and sell the value of our solutions and services relative to competitors. - Ensure partners receive timely product and MSP/MSSP model updates for each relevant product area, and work with internal teams to build service offerings and develop launch content. - Drive program management and governance for service offering launches across your named accounts. - Develop and drive KPI metrics to assess partnership effectiveness, regularly reviewing partner engagement and performance and adjusting strategy as needed — with a demonstrable track record of setting and hitting financial goals with focus partners. - Ensure each named partner is equipped with the tools and resources to scale their go-to-market and compete effectively, and establish enablement goals that validate partners meet the training, certification, and support requirements of the partner program. - Evangelize partner service offerings and bring the voice of the partner back into SentinelOne's sales organization. - Prepare and deliver accurate forecasts of revenue for your named book of business. - Partner cross-functionally with Sales Engineering, Professional Services, Customer Success, Marketing, and Support to reduce churn, close deals, and drive revenue and product adoption. - Stay aligned with the Director, Global MSSP Ecosystem Sales, and peer Partner Development Managers on forecasting, enablement, and the launch of newly created solutions with your partners. What Skills and Knowledge Will You Bring? - BS technical degree or equivalent work experience. - 5+ years of above-quota sales experience, preferably as a Regional Sales Executive/Manager selling security solutions across endpoint, identity, data, and cloud. - Strong partner background across Managed offering providers — MSP, MSSP, MDR, XDR, outsourcers, distribution, and systems integrators. - Experience managing a concentrated, named book of strategic accounts rather than a broad territory — comfort with fewer, deeper relationships, ideally with a track record of driving double- or triple-digit revenue growth at the partner level. - Deep knowledge of current security solutions, including indirect/managed sales motions (fully managed, co-managed, single- and two-tier; CSP marketplace experience a plus). - Strong written and verbal communication and presentation skills, with the ability to engage a variety of technical and business leaders internally and externally, including at the executive level. - Enterprise sales experience with an actionable network of MSSP decision makers. - Superb organizational and reporting skills. - Experience growing the sales enablement function to support sales in a rapidly evolving, competitive marketplace. - Motivated, focused self-starter with strong leadership skills, able to multitask and work both independently and collaboratively within a team. - A “whatever it takes” attitude and motivation to deliver above-quota performance. - Prior startup experience. - Experience working with channel partners and a strong understanding of partner-centric go-to-market approaches. - Smart, funny, technical, and passionate about security! Why us? AI is redefining how the world operates and rewriting the rules of security in real time, and SentinelOne was built for this moment. From day one, we architected an AI-native platform designed to operate at machine speed, not as an add-on to legacy systems but as the foundation itself.
