About the Role

Polymarket is looking for a world-class infrastructure engineer to join our team and help scale the systems that power our products. You’ll be responsible for designing, building, and maintaining the backbone of our engineering platform—from developer workflows and CI/CD pipelines to core infrastructure that supports high-performance APIs and data services. You’ll have the autonomy to make big technical decisions, drive system architecture, and implement solutions that balance speed, reliability, and long-term maintainability.

What You’ll Do

We're looking for an experienced individual contributor who enjoys optimizing mission-critical infrastructure.

• Build & automate development workflows. You’ll design and maintain infrastructure that standardizes how we develop, version, test, and deploy software across environments.

• Architect scalable systems. You’ll make thoughtful architectural decisions and tradeoffs, balancing risk, performance, cost, and maintainability.

• Power high-performance services. You’ll contribute to infrastructure supporting real-time APIs and low-latency data feeds.

• Develop testing infrastructure. You’ll build robust tooling for automated testing at all levels—from unit to integration to API.

• Ensure availability & reliability. You’ll own critical infrastructure that minimizes downtime and reduces risk of failure.

• Move fast without breaking things. You’ll deliver high-quality solutions quickly, with a strong sense of ownership and attention to detail.

• Operate autonomously. You’ll take initiative and make independent decisions—no micromanagement here.

• Collaborate across teams. You’ll work closely with engineers throughout the company to support deployment, performance, and operational needs.

• Excellent communication skills and a strong desire to learn, grow, and collaborate effectively across teams.

• Solid technical acumen and a results-driven mindset, capable of solving complex engineering challenges with practical solutions.

• Proven history of improving engineering workflows, through the creation and implementation of new tools and processes that boost efficiency and consistency.

• Leadership experience in planning and executing large-scale projects, with lasting impact on core systems or engineering teams.

• Ability to ship quickly and iterate fast, without compromising quality.

• Exceptional judgment in prioritizing tasks, balancing urgency with strategic importance.

• Growth-oriented mindset, with a steep learning curve and an eagerness to evolve with the role.

• Genuine passion for engineering—you take pride in your craft and strive for excellence in everything you build.

• Specialized expertise in at least one of the following areas:

  • Networking: demonstrated ability to diagnose and resolve complex network-related issues.

  • Security: Relevant certifications, such as CISSP, CISM, or AWS certifications, or equivalent experience in designing secure systems.

• (PLUS) Proven experience building deployment systems in:

  • K8S

  • RDS / PSQL

  • IAM policies/roles

  • ElasticCache

  • Cloud Networking (VPC peering, subnets, etc)

Benefits

• Competitive salary & equity

• Unlimited PTO, Health, Vision, & Dental coverage
