About this role
Join Polymarket as a Cloud Security Engineer to enhance AWS security posture, design security controls, and collaborate with engineering teams in a fast-growing prediction market platform.
Description
About Polymarket
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.Responsibilities
What You'll Do
- Own and continuously improve Polymarket's AWS security posture across accounts, regions, and services — including IAM policies, SCPs, VPC segmentation, and account-level security baselines
- Review and contribute to IaC modules that encode security defaults; integrate automated security checks into the deployment pipeline including policy-as-code validation and misconfiguration scanning
- Own cloud-side security telemetry: CloudTrail, GuardDuty, Security Hub, Config Rules, VPC Flow Logs, and S3 access logging
- Develop and tune detection logic for cloud-specific threats; partner with the SOC team on alert fidelity, incident response runbooks, and AWS-level investigations
- Govern secrets management using AWS Secrets Manager and SSM Parameter Store; manage KMS key policies, rotation, and envelope encryption patterns
- Drive remediation of findings from AWS Inspector, Security Hub, and third-party CSPM tooling; maintain benchmarks aligned to CIS AWS Foundations
- Support audit and compliance activities (SOC 2, PCI-DSS, or similar) and conduct regular access reviews to identify and remediate privilege creep
Requirements
What We're Looking For
- 4+ years of experience in cloud security, cloud engineering, or a security-focused infrastructure role
- Deep, hands-on expertise with AWS security services: IAM, SCP, GuardDuty, Security Hub, CloudTrail, Config, KMS, WAF, Inspector, and VPC
- Hands-on experience writing infrastructure as code (Pulumi, Terraform, CDK, or equivalent) with a security-first mindset
- Strong understanding of AWS networking and how misconfigurations translate to real attack surface
- Proficiency in at least one scripting or programming language (Python, TypeScript, or Go) for automation and tooling
- Ability to evaluate architectural decisions for security risk and communicate findings clearly to engineering peers
- (Plus) Familiarity with Pulumi, specifically TypeScript-based stacks
- (Plus) Familiarity with Web3, blockchain infrastructure, or crypto-sector threat models
- (Plus) Experience securing containerized workloads on ECS or EKS, including image scanning and runtime security
- (Plus) AWS certifications: Security Specialty, Solutions Architect — Professional, or equivalent
- (Plus) Exposure to SOC 2 Type II or PCI-DSS cloud control requirements
