About The Position

BigMarker is seeking a skilled, solutions-oriented, customer-facing Front End Engineer to connect its core platform with bespoke event experiences for enterprise clients. The role combines front-end development expertise with communication skills and a focus on polished, high-converting user interfaces. The engineer works directly with enterprise customers to architect, build, and deploy custom event experiences, tailored registration flows, and complex front-end API integrations.

The position involves developing responsive event portals and interfaces aligned with customer brand guidelines, creating reusable UI components and interactive widgets, and ensuring security, accessibility, and rendering efficiency for high-concurrency live events. It also requires working with clients and agencies to gather requirements, advise on technical options and UI/UX practices, communicate trade-offs and timelines, and integrate the platform with third-party tools. The engineer troubleshoots reported front-end issues and CSS/JavaScript conflicts. Applicants must be legally authorized to work in the United States; visa sponsorship is not available.

• 3–5+ years of professional Front-End Engineering experience, with a strong portfolio of production-grade responsive web applications or custom client experiences.
• Deep proficiency in semantic HTML5, modern CSS3 (including Flexbox, Grid, animations, and preprocessors), and JavaScript (ES6+) / TypeScript.
• Familiarity with modern web frameworks and server-rendered environments, such as React, Vue, or Node.js.
• Prior customer-facing experience, such as Solutions Engineering, digital agency, or another role involving direct collaboration with external stakeholders.
• Strong eye for design detail and typography, and ability to translate Figma or Adobe XD mockups into pixel-perfect, high-converting interfaces.
• Fluency in browser DevTools, network inspection, and performance profiling; ability to resolve cross-origin (CORS) or third-party script conflicts safely.
• Excellent written and verbal communication skills for collaborating with internal engineers and non-technical clients.

Nice To Haves

Responsibilities

• Architect, develop, and deploy bespoke, responsive event portals and custom interfaces tailored to enterprise customer brand guidelines.
• Build reusable, modular UI components and interactive widgets that extend the live webinar and post-event experience.
• Ensure front-end code security, accessibility (WCAG), and rendering efficiency across global, high-concurrency live events.
• Partner directly with enterprise clients and agencies to gather technical requirements, evaluate feasibility, and translate business goals into functional web experiences.
• Provide technical guidance and best-practice recommendations on UI/UX optimization, page load speeds, and front-end architecture.
• Communicate technical concepts, trade-offs, and timelines clearly to technical and non-technical stakeholders.
• Implement front-end integrations connecting the platform with third-party automation, CRM, and SSO tools via REST APIs and custom scripts.
• Analyze, troubleshoot, and resolve customer-reported front-end issues and CSS/JavaScript conflicts in real time.
