Senior Web Developer

About Quantcast

At Quantcast, were redefining whats possible in digital advertising. As a global Demand Side Platform (DSP) powered by AI, we help marketers connect with the right audiences and deliver measurable results across the open web. Our foundation is built on cutting-edge measurement and consumer analytics, giving our clients the tools they need to drive success in an ever-evolving digital landscape.

The Role

We are looking for a Senior Web Developer (IC4) to join our IT Enterprise Applications team. This is a high-impact, senior individual contributor role designed for a "technical athlete" who can move fluidly between complex code and operational architecture. You will own the performance, deployment, and data integrity of quantcast.com.

As an IC4, you aren't just executing tasks; you are architecting the bridge between Marketings vision and high-performance engineering. You will lead the transition toward a modern, headless approach, managing a stack that includes Builder.io (CMS), Google Tag Manager (GTM), and Salesforce. While your background may be in traditional web technologies, a key component of this role is the proactive willingness and ability to learn how to deploy Salesforce Lightning Web Components (LWC) to unify our front-end and CRM ecosystems.

What Youll Do

• Architectural Ownership (40%): Lead the technical strategy for our headless CMS (Builder.io) and GTM instrumentation. Define standards for custom HTML tags, complex triggers, and data layer governance to ensure high-fidelity marketing analytics.
• Custom Engineering & LWC (30%): Develop modular, standalone ES6+ JavaScript. A critical focus will be the development and maintenance of Salesforce Lightning Web Components (LWC) (optional but a bonus) to create seamless data bridges between our web presence and Salesforce.
• DevOps & Automation (20%): Own and optimize our CI/CD pipelines. You will design and maintain GitHub Actions workflows to automate testing and deployment, ensuring a "fail-safe" global shipping velocity.
• Strategic Stakeholder Leadership (10%): Act as a technical consultant to Marketing and Engineering leadership. You will translate high-level business goals into scalable technical specifications and lead the "triage" of complex, cross-system issues.

Key Performance Indicators (KPIs)

• System Reliability: Significant reduction in manual deployment errors through advanced automation.
• Architectural Flexibility: Successful implementation of custom JS and LWC solutions that bypass standard "out-of-the-box" tool limitations.
• Data Accuracy: Perfect synchronization between web interactions (GTM/DataLayer) and downstream Salesforce lead tracking.
• Execution Velocity: Measured improvement in the time-to-market for global marketing initiatives.

Who You Are

• Education: Bachelors Degree or higher in Computer Science, Information Technology, or a related field.
• Experience: 5+ years of professional web development experience in a complex, global environment. (We value expertise and demonstrated impact; if you have 4 years of extraordinary results, we still want to hear from you).
• Technical Mastery:
• Advanced JavaScript: Expert-level ES6+ skills are mandatory.
• LWC Willingness: You must have a strong desire to work within the Salesforce ecosystem. Whether you are already an LWC expert or a Senior JS Developer ready to master it, willingness to own LWC development is key to this role.
• Headless & MarTech: Proven experience with API-first CMS platforms (Builder.io preferred) and expert-level Google Tag Manager (GTM) management.
• Modern DevOps: Practical experience writing YAML for GitHub Actions and managing automated deployment environments.
• The "Technical Athlete" Mindset: You are comfortable debugging a tracking pixel one hour and architecting a global deployment workflow the next.
• Communication: Exceptional ability to distill complex technical constraints into clear strategic options for non-technical stakeholders.

Preferred Skills & Certifications

• Google Analytics/GTM Professional Certification.
• Experience mentoring junior developers or establishing documentation standards for technical teams.
