[Hiring] Senior Web Engineer @Polymarket

Role Description

Polymarket is looking for a Senior Web Engineer to own complex frontend features, improve reliability, and help us ship faster with confidence. You'll own major web surfaces end-to-end: from scoping and implementation through launch, monitoring, and production support. This is a high-ownership role at the intersection of frontend product development, backend systems, performance, and reliability.

You should have experience in crypto and be comfortable shipping complicated React/Next.js features, debugging ambiguous production issues, and working across teams without needing hand-holding. We want someone who can move fast, make strong technical decisions, and help raise the quality bar for our frontend systems.

What You'll Do

• Own and ship complex features end-to-end.
• Build and launch web features across Polymarket's core product surfaces, making thoughtful tradeoffs between speed, quality, architecture, and long-term maintainability.
• Collaborate across the stack.
• Work closely with backend engineers to design APIs, reason through data flows, and build reliable user experiences on top of complex systems.
• Partner with QA, TPM, product, and design to clarify requirements, manage launches, and improve product quality.
• Own reliability and incident response for your domain.
• Monitor dashboards, alerts, and user reports to identify and respond to issues quickly.
• Work with backend and infrastructure teams during incidents to isolate root causes, ship mitigations, and follow through with fixes and prevention work.
• Improve frontend observability.
• Build and improve the logs, metrics, alerts, dashboards, and error reporting that give the team visibility into how our frontend systems are performing.
• Raise the engineering bar.
• Identify meaningful technical debt, propose pragmatic refactors, and contribute to system design discussions that evolve our frontend architecture as the product scales.
• Lead by example through strong code reviews, clear communication, and high-quality execution.
• Tie technical work to outcomes.
• Connect your work to measurable results – performance, reliability, product quality, and conversion – and help break down ambiguous product requirements into shippable engineering work.

Qualifications

• 5+ years of frontend web engineering experience with experience in crypto, Web3, or adjacent financial infrastructure.
• Strong hands-on experience with React, Next.js, TypeScript, and modern frontend development.
• Strong frontend system design instincts across state management, data fetching, caching, performance, reliability, and maintainability.
• Experience owning complex features from scoping through launch.
• Strong debugging skills and experience responding to production issues.
• Comfortable working with backend engineers on APIs, data contracts, failure modes, and system behavior.
• High agency: you notice problems, propose solutions, and drive work to completion.
• Product-minded: you care about user experience, not just implementation.
• Able to operate independently in a fast-moving, ambiguous environment.
• Clear communicator during planning, launches, bugs, and incidents.
• (Plus) Frontend performance specialization.
• (Plus) Experience with high-traffic, real-time, marketplace, trading, or financial products.
• (Plus) Experience building for WebViews or shared web/mobile surfaces.
• (Plus) Experience improving frontend observability, alerting, or reliability practices.
• (Plus) Strong practical use of AI tools to improve engineering productivity.

Benefits

• Competitive salary & equity.
• Unlimited PTO.
• Full Health, Vision, & Dental coverage.
• 401k match.
• Hardware setup: new MacBook Pro, big display, & accessories.
