Job description

ABOUT ROLR

ROLR is building a prediction markets platform delivering the frontier of trading on sports, culture, economics, AI, commodities, and geopolitics.

You’ll be on a nimble startup-like team within a public company. Our customer experience spans mobile and web, from markets and live trading interfaces to onboarding, identity, payments, and operational tools. Our differentiation lives before the cashier: the game, the graph, and the notification. The consumer surface is the asset we own outright under every scenario, and this role will play a key part in building it.

Role Overview

We're looking for a Senior Frontend Engineer to join our team in New York and build the customer-facing experience of our prediction markets platform across web and mobile. You'll work across React, React Native, and TypeScript, building complex real-time consumer experiences with significant ownership from idea through production. This is not a role focused simply on implementing tickets. We're looking for engineers who think like product builders.

Key Responsibilities
  • Design and build customer-facing experiences using React, React Native, and TypeScript

  • Develop trading interfaces, live positions, settlement views, wallet and payout flows, identity and verification journeys, and promotions

  • Build real-time interfaces using live data feeds and WebSockets that remain reliable under live market conditions

  • Build sign-up, sign-in, and session flows against our Keycloak-standardized identity platform: OAuth 2.0 / OIDC with PKCE, token lifecycle, passkeys (WebAuthn), and biometric step-up on native surfaces

  • Develop and contribute to the shared web and React Native design system

  • Ensure consistent experiences across web and mobile, including design tokens, touch targets, and live-ticking numerals in fixed-width slots

  • Work across internal and partner-maintained frontend codebases and review partner work to a high standard

  • Maintain strong frontend architecture and appropriate boundaries between ROLR and external platform providers

  • Build and improve internal back-office tools and operational dashboards

  • Monitor and improve frontend performance, including Core Web Vitals on web and cold start and frame time on native

  • Support code reviews, architecture discussions, and mentoring across the engineering team


You’ll need to:
  • Have 5–7 years of professional frontend engineering experience

  • Have deep React experience and strong TypeScript and JavaScript skills

  • Have experience building complex production web applications

  • Have experience with real-time interfaces, WebSockets, or streaming data

  • Have implemented authentication in production, including OAuth 2.0 / OIDC flows, token lifecycle, and secure session handling

  • Have experience building accessible interfaces (WCAG 2.1 AA)

  • Have strong HTML, CSS, responsive design, and API integration experience

  • Have strong debugging and frontend performance skills

  • Be comfortable working across Product, Design, Backend, QA, and Compliance

  • Be based in New York and work out of our New York office

Preferred Experience
  • React Native in production, strongly preferred given our flagship mobile product

  • Design systems, tokens, theming, and component libraries

  • Keycloak or comparable identity platforms, passkeys / WebAuthn, and biometric unlock

  • Real-time market data or trading interfaces

  • Fintech, trading, prediction markets, or another regulated industry

  • Internal/admin tooling frameworks and frontend observability, such as Sentry or Datadog RUM

  • AI-native engineering workflows, including agentic coding and AI-assisted testing and review

What We Offer
  • Base salary range: $180,000–$240,000 per year. Offers will be positioned within the range based on experience and qualifications

  • Competitive health and welfare benefits

  • 401(k) retirement plan with company match

  • Flexible vacation policy

  • Home office setup reimbursement

  • Access to mental health support
