Senior Web Engineer
"What You'll Be Doing"
What You'll Be Doing
Own and ship complex features end-to-end across Polymarket's core product surfaces, balancing speed, quality, architecture, and long-term maintainability.
Collaborate closely with backend engineers on API design and data flows to build reliable user experiences on top of complex systems, while partnering with QA, TPM, product, and design to clarify requirements, manage launches, and improve quality.
Own reliability and incident response for your domain — monitoring dashboards, alerts, and user reports, and working with backend and infrastructure teams to isolate root causes, ship mitigations, and follow through on fixes and prevention.
Improve frontend observability by building and refining logs, metrics, alerts, dashboards, and error reporting.
Raise the engineering bar by identifying technical debt, proposing pragmatic refactors, contributing to system design discussions, and leading through strong code reviews and clear communication.
Tie technical work to measurable outcomes — performance, reliability, product quality, conversion — and help break down ambiguous product requirements into shippable engineering work.
What We're Looking For
5+ years of frontend web engineering experience, including 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
Comfort working with backend engineers on APIs, data contracts, failure modes, and system behavior
High agency — noticing problems, proposing solutions, and driving work to completion
A product mindset that cares about user experience, not just implementation
Ability to operate independently in a fast-moving, ambiguous environment
Clear communication during planning, launches, bugs, and incidents
Bonus Points
Frontend performance specialization
Experience with high-traffic, real-time, marketplace, trading, or financial products
Experience building for WebViews or shared web/mobile surfaces
Experience improving frontend observability, alerting, or reliability practices
Strong practical use of AI tools to improve engineering productivity
