Senior Software Engineer

Senior Software Engineer

As a Senior Software Engineer, you will be at the core of one of the most technically demanding challenges in modern web infrastructure: optimizing how web traffic is intercepted, processed, and delivered at massive scale across an edge computing platform. You will work on a system handling tens of thousands of requests per second and tens of billions of dollars of annual e-commerce volume, alongside a small, high-caliber engineering team where every engineer owns a meaningful piece of the system.

This is not a ticket-execution role. You will be a technical leader in architecture and design, collaborating directly with the CTO and lead platform engineer to define how the platform evolves. You will plan rollouts methodically, define success metrics before shipping, debug complex cross-browser and cross-device behavior, and build systems that cannot fail.

Responsibilities

• Design, build, and scale the core platform infrastructure handling high-volume web traffic at the CDN and edge computing layer
• Take an active technical leadership role in architecture design, technical planning, and authoring design documents with a long-term view
• Plan and execute gradual, methodical rollouts: define target audiences, KPIs, and success metrics before shipping significant changes
• Debug complex front-end behavior caused by backend platform changes across all browsers, devices, and geographies
• Collaborate with the data engineering team to ensure testability at scale and build the right measurement and observability framework
• Solve high-complexity technical problems with significant scope and ambiguity, where few established playbooks exist
• Mentor engineers and serve as a point of technical escalation for complex platform challenges
• Stay current with emerging web performance technologies, edge computing patterns, and browser optimization techniques
• Embrace and integrate AI coding tools into your engineering workflow to accelerate delivery and improve code quality
