• Formalize and drive the technical roadmap and operational excellence for the system, leading the design and architecture of medium-to-large components and driving cross-team standardization
• Serve as the technical lead for high-risk, cross-functional consent and compliance rollouts that directly impact advertising revenue and legal requirements, and design and implement proactive risk-mitigation strategies such as bucketed or percentage-based rollout controls
• Lead strategic initiatives such as third-party CDN proofs of concept (for example, Cloudflare and Fastly WASM-based solutions) to establish repeatable, portable architectural patterns for the customer’s edge organization in support of long-term digital transformation and cost optimization
• Establish system guardrails and improve core system quality, including comprehensive automated test coverage and platform-agnostic testing frameworks to eliminate critical regressions and ensure service stability
• Translate complex technical and legal requirements across privacy, legal, and advertising teams, and provide mentorship and guidance to peers and dependent teams
• Translate ambiguous, high-level business and compliance needs into reliable, globally-deployed system solutions

Requirements:

• 8+ years of professional software development at a senior level

• Direct work on high-performance HTTP proxies (Apache Traffic Server, Nginx) or CDNs, with real HTTP/1.1 and HTTP/2 depth
• Linux kernel / systems-level troubleshooting and crash analysis
• Ownership of a mission-critical, globally-deployed system, including automated test suites and CI/CD quality gates
• Proven software development experience performing at or beyond a Senior (IC4) level, typically 8+ years of professional experience
• Demonstrated track record of owning mission-critical, high-availability, globally-deployed production systems
• Strong, hands-on experience with C, C++, Python, and WASM toolchains
• Strong working knowledge of HTTP/1.1 and HTTP/2, including headers, cookies, caching, and connection handling in the context of edge proxies
• Direct experience with high-performance HTTP proxies (for example, Apache Traffic Server / ATS or Nginx) or Content Delivery Networks (CDNs)
• Solid understanding of the Linux kernel, networking, and systems-level troubleshooting
• Good understanding of crash analysis

• Familiarity with consent and privacy management platforms (for example, Didomi) and global privacy regulations such as GDPR and CCPA
• Experience designing bucketed or percentage-based rollout controls for safe, gradual global deployments
• Prior experience mentoring peers and guiding dependent engineering teams
