Position Summary

As a Senior Solutions Engineer, you serve as the technical architect and primary expert for our most complex, high-stakes client engagements. You bridge the gap between sales and engineering by designing bespoke integrations and executing advanced workstreams across APIs, SQL, and deep-funnel troubleshooting for sophisticated AdTech stacks. While providing a technical lighthouse for the team, your focus is on solving "first-of-their-kind" challenges and partnering directly with Product and Engineering leadership to drive feature development and resolve systemic platform issues. Ultimately, you are responsible for harmonizing cutting-edge technology with high-level business goals to ensure seamless platform adoption and superior campaign performance for strategic partners.

Key Responsibilities

• Act as the technical expert in complex, multi-stakeholder sales cycles.
• Develop advanced, custom-coded Proofs of Concept (PoCs) and interactive demos that go beyond standard platform features to solve unique client problems.
• Serve as the final escalation point for "unsolvable" technical issues.
• Use SQL, JavaScript, and APIs to debug deep-funnel tracking discrepancies, server-to-server integration errors, and complex GTM/pixel configurations.
• Act as the primary bridge between the field and the Product/Engineering teams. Translate complex client requirements into technical specifications for new features and help prioritize the product roadmap based on technical feasibility and market demand.
• Leverage BigQuery and big data tools to perform deep-dive analysis on campaign performance. Build custom dashboards and automated reporting scripts to provide clients with insights that standard UI reporting cannot capture.
• Own the technical narrative for major global bids, ensuring all security, privacy (GDPR/CCPA), and infrastructure requirements are met with precision.
• Develop and maintain reusable code libraries, technical best practices, and sophisticated documentation to elevate the technical output of the entire Solutions Engineering organization.

Qualifications

• Expert-level mastery of programmatic advertising, including OpenRTB specifications, VAST/VPAID protocols, and the mechanics of Header Bidding, DSPs, and SSPs.
• Professional-level proficiency in JavaScript (beyond basic tags), SQL (complex joins and data modeling), and HTML/CSS.
• Extensive experience with the Google Marketing Platform (DV360, CM360, GA4), CDPs, and Clean Room environments.
• A "systems-thinking" approach to troubleshooting; the ability to identify root causes in distributed systems and propose scalable fixes.
• Preferred: 6+ years in a client-facing technical engineering role. You should have a proven track record of successfully delivering high-value technical projects and navigating the complexities of the AdTech landscape.
• A bachelor’s degree in Computer Science, Software Engineering, or a related quantitative field is highly preferred.
