Customer Experience Representative

Backend Engineer

• Own the CLOB engine's critical path. Profile matching and orderbook hot paths, map settlement-sensitive state transitions, and drive improvements to latency, throughput, and async engine flow backed by benchmarks and production-grade evidence.
• Reduce lock contention without breaking correctness. Debug concurrency issues, design safer queueing and backpressure for orderbooks, and improve the system's ability to handle materially more markets and order flow with lower tail latency.
• Build for observability and safety. Instrument improvements with pprof, metrics, logs, and traces. Establish rollback guarantees and narrower critical paths that make production incidents easier to detect, diagnose, and resolve.
• Reason about settlement risk. Understand how on-chain transaction effects ripple into off-chain exchange state, and design systems that handle crossed books, ghost fills, stale orders, cancel inconsistencies, and settlement edge cases correctly.
• Improve the runtime. Reduce GC pressure, optimize CPU and memory allocation behavior, and push Go runtime performance to meet the demands of a high-throughput exchange at scale.
• Debug production incidents. Own latency, correctness, and settlement-state incidents end-to-end, and drive follow-through that leaves the system measurably better each time.

Escalation Engineer, CX

Full-stack Engineer

• Improve APIs, SDKs, and docs. Own the quality, consistency, and usability of Polymarket's developer-facing surfaces – finding gaps, fixing them, and raising the bar for what great developer experience looks like.
• Reduce time to first success. Identify integration friction and turn it into practical improvements that help external developers get up and running faster. You'll ramp quickly on our APIs, SDKs, and docs and ship meaningful improvements early and often.
• Partner across engineering. Work closely with engineers to improve usability, consistency, and quality across developer-facing systems, becoming a trusted contributor across key Dev Tooling initiatives over time.
• Close the feedback loop. Debug developer issues, gather signals from how developers are getting stuck, and use those insights to guide what gets built next.
• Operate with autonomy and impact. Drive high-impact Dev Tooling workstreams independently, with strong product judgment and measurable results on developer experience and adoption.
• Ship with leverage. Use AI consistently as part of your development workflow – to accelerate implementation, debugging, and documentation – while maintaining quality and sound technical judgment.

Software Engineer, Dev Tools

Frontend Engineer

• 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.

Senior Web Engineer

Data Engineer

• Own the OLAP analytics layer. Drive our columnar warehouse environment end-to-end: raw event ingestion → cleaned facts and dimensions → business aggregates → API-serving views. You'll own materialized view design, refresh cadences, dictionary catalog, query planning, and cost optimization.
• Partner on the OLTP serving layer. Work closely with the team on high-write serving tables that back our product APIs – partition strategy, indexing, trigger pipelines, autovacuum tuning, and bloat monitoring – with sub-100ms read-path discipline.
• Shape streaming and data lake infrastructure. Define Kafka topic schema contracts, evolve the S3 lake layout with modern table formats, and contribute to parity-validation tooling that guards data correctness under migration pressure.
• Design data models at scale. Work with event-sourced, append-mostly data with chain-reorg semantics. Design the derivative analytics – PnL, realized/unrealized position tracking, cohort metrics – and formalize ownership boundaries between upstream ingestion and downstream analytics.
• Coordinate across teams. Negotiate schema contracts with the warehouse-owning team and downstream consumers including frontend, notifications, and third-party integrators.
