About The Position

We are seeking a highly skilled and experienced Senior Software Development Engineer (IC4) to support a critical customer engagement focused on edge infrastructure, consent and privacy compliance, and global system reliability. This role is ideal for a deeply technical, ownership-minded engineer who can take a mission-critical, globally-deployed system end to end — setting its technical direction, hardening its quality, and steering high-risk compliance rollouts with minimal oversight. The successful candidate will work closely with the program manager and customer stakeholders to ensure project success from initial definition through final delivery.

Requirements

• 8+ years of professional software development at a senior level.
• Production, hands-on C and C++ (plus Python and WASM toolchain exposure).
• 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.
• Practical experience building comprehensive automated test suites and integrating quality gates into CI/CD pipelines for mission-critical systems.
• Proven ability to lead technical initiatives and complex problem-solving in high-risk production environments.
• Strong awareness of system dependencies and business impact, with experience managing complexity and tradeoffs.
• Excellent cross-functional communication and collaboration skills, including the ability to translate complex technical and legal requirements to non-technical audiences.

Nice To Haves

• Hands-on experience with third-party CDN platforms such as Cloudflare or Fastly, including WASM-based edge solutions.
• 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.

Responsibilities

• Maintain full technical ownership of the customer’s cookie and consent management plugin, including its deployment, performance, and stability across all consuming properties.
• 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.
