GRC & Privacy Lead

Polymarket is the world's largest prediction market platform. We enable individuals to express views on real-world events by trading on outcomes across politics, economics, sports, culture, and current affairs. Built as a peer-to-peer marketplace with no centralized "house," Polymarket aggregates diverse opinions into transparent, market-based probabilities that reflect collective expectations about the future.

We're growing fast — both in terms of volume ($21B traded in 2025) and adoption as an alternative news source. Our ambition is to become a ubiquitous beacon of truth in global media and we need your help adding fuel to the fire.

Polymarket's IT and Security team is small, senior, and expected to move fast. This role sits at the intersection of third-party risk, audit execution, and privacy operations — and the person in it will own all three. DSARs need to be processed, vendors need risk dispositions before they get access to our systems, and PIAs need to happen before engineering ships, not after.

This is a senior IC role. You'll make judgment calls independently, build processes that didn't exist before you arrived, and leave behind documentation the team can actually use. We have active audit work underway, a vendor pipeline that needs rigorous day-to-day management, and privacy obligations spanning GDPR, CCPA/CPRA, BIPA, CUBI, and the specific data flows that come with KYC and identity verification at scale.

• →

  Triage vendor intake requests daily, assess inherent risk based on data sensitivity and system connectivity, and route appropriately — including flagging vendors that require PIAs or DPA review before onboarding

• →

  Analyze vendor assurance documentation — SOC 2 reports, ISO certifications, PCI AOCs, and penetration test summaries — and produce clear written risk memos with defensible dispositions

• →

  Gather and organize evidence for our active SOC 2 Type II engagement, coordinate with control owners to close requests on time, and manage submissions through the auditor portal from start to finish

• →

  Process DSAR requests across multiple corporate entities, applying correct retention exemptions and routing logic, and track fulfillment to meet statutory deadlines

• →

  Run privacy impact assessments for new product features and vendor onboarding, working directly with product and engineering to identify risks before they ship

• →

  Maintain the policy library, track review and acknowledgment cycles, and own remediation tracking for vendor and audit findings through to resolution

• →

  Help implement and operationalize our privacy compliance platform, including building out the data inventory and mapping flows that reflect how we actually collect and process personal data

• Hands-on SOC 2 Type II audit experience — you have personally gathered evidence, coordinated with control owners, and managed auditor requests through a full engagement cycle

• Demonstrated experience conducting third-party vendor risk assessments, including reading and interpreting SOC 2 reports, PCI AOCs, and pen test summaries, and writing risk memos with clear dispositions

• Working knowledge of GDPR, CCPA/CPRA, BIPA, and CUBI, and the ability to translate those obligations into concrete process steps that product and engineering teams can follow

• Experience building compliance or privacy processes from scratch, not just inheriting and maintaining them

• Comfort operating independently, triaging ambiguous situations, and making defensible decisions without waiting for escalation on routine assessments

• (Plus) Experience with PCI DSS scoping or self-assessment activities

• (Plus) Familiarity with KYC and identity verification data flows and the privacy considerations specific to biometric and identity data

• (Plus) Prior experience at a crypto, fintech, or prediction market company
