What are the responsibilities and job description for the Enterprise Sales Director position at Sentinel / Proxy?
About Sentinel / Proxy:
Sentinel/Proxy is a pioneering forensic intelligence platform built (established in 2023) to fix what's broken in the programmatic supply chain. Using bidstream-level analysis, and aligning on the 2026 MRC Standards, the platform surfaces inefficiencies that most agencies never see; hop inflation, structured arbitrage, and hidden fee extraction and goes beyond observation by integrating findings directly into DSP controls.
The approach is straightforward: audit losses, enforce policies, and establish verifiable standards. Sentinel/Proxy transforms financial transparency from a talking point into a measurable competitive advantage.
About the Opportunity:
- This is a senior individual contributor role for a hunter who thrives in consultative, complex enterprise deals.
- You will own the full sales cycle; from identifying and qualifying accounts to closing six-figure forensic audit engagements.
- Your primary targets are media agencies and brand advertisers with $3M or more in annual programmatic spend.
- You'll report directly to the Lead Architect and have a defining role in building the commercial engine from the ground up.
What you will do:
- Identify, research, and prioritize agencies and brands with $4M in programmatic spend, building a high-conviction pipeline from the ground up.
- Lead consultative discovery: engage CFOs, procurement leads, and programmatic directors to diagnose exposure around ad fraud, undisclosed fees, and supply path waste.
- Sell forensic audit engagements: position Sentinel/Proxy's bidstream methodology as the accountability standard for enterprise programmatic buyers, from initial scoping through signed contract.
- Navigate complex buying committees: build multi-threaded relationships across legal, finance, and media teams to drive consensus and compress deal timelines.
- Manage the full sales lifecycle: from lead generation and pipeline development through onboarding and ongoing account management, ensuring long-term client satisfaction and expansion.
- Feed intelligence back to the business: translate frontline conversations into insights that sharpen product positioning, pricing strategy, and roadmap priorities.
Who we are looking for:
- 5 years of enterprise sales experience in ad tech, martech, media auditing, or programmatic platforms, with a consistent track record of meeting or exceeding revenue targets.
- Proven ability to close six-figure, consultative deals with media agencies, holding companies, or large brand advertisers.
- Deep fluency in programmatic advertising: DSPs, SSPs, trading desks, fee structures, supply path optimization, MFA inventory, and ad fraud dynamics.
- Strong existing network within agency holding groups (WPP, Omnicom, Publicis, IPG, Dentsu) or large independent agencies is a significant advantage.
- Skilled negotiator with strong presentation and interpersonal communication abilities across technical and non-technical stakeholders.
- Proficient in CRM software and sales analytics tools; self-directed and comfortable operating in a lean environment.
- Bachelor's degree in Business, Marketing, or a related field required; MBA is a plus.
Compensation Structure:
- Commission, Uncappped
- 50% of supply chain audit fees 2% of recovered capital
Why this role matters: The programmatic supply chain is leaking money at scale and most of the industry has either normalized it or lacks the tools to prove it. Sentinel/Proxy changes that equation. This is a rare opportunity to be the commercial face of a category-defining platform early enough to shape the strategy, with the credibility of a product that wins the moment you show the data.
