Heads-up
Requirements and responsibilities
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.ResponsibilitiesDesign, build, and scale the core platform infrastructure handling high-volume web traffic at the CDN and edge computing layerTake an active technical leadership role in architecture design, technical planning, and authoring design documents with a long-term viewPlan and execute gradual, methodical rollouts: define target audiences, KPIs, and success metrics before shipping significant changesDebug complex front-end behavior caused by backend platform changes across all browsers, devices, and geographiesCollaborate with the data engineering team to ensure testability at scale and build the right measurement and observability frameworkSolve high-complexity technical problems with significant scope and ambiguity, where few established playbooks existMentor engineers and serve as a point of technical escalation for complex platform challengesStay current with emerging web performance technologies, edge computing patterns, and browser optimization techniquesEmbrace and integrate AI coding tools into your engineering workflow to accelerate delivery and improve code qualityRequirements5-10 years of software engineering experience with a strong background in building and scaling high-traffic, multi-tenant web platformsExpert-level proficiency in TypeScript (primary language), JavaScript (real JS, not just framework-level), and PythonDemonstrated experience designing and operating distributed, high-availability systems at meaningful scaleCloud platform experience: AWS, GCP, or Azure (cloud agnostic environment)Experience with CDN infrastructure and web performance optimization: tools such as Cloudflare, Lighthouse, WebPageTest, and techniques such as web workers, lazy loading, and code splittingInfrastructure as Code experience (Pulumi or equivalent)Strong SQL and data querying skills; ability to work with data warehouses and build data-driven engineering decisionsExperience with message queues (SQS, Kinesis, or equivalent) and CI/CD pipelinesData storage: PostgreSQL, Redshift, or equivalentStrong problem-solving skills and detail orientation: understands that at massive traffic scale, edge cases are not edge casesActive AI tool usage in engineering workflow: Claude Code, GitHub Copilot, Codex, or equivalentStrong English communication: comfortable in technical discussions and async written collaboration with a distributed teamAvailable to work full Eastern Standard Time hoursPreferredCloudflare Workers or edge computing experience (highly preferred given the platform architecture)E-commerce platform experience: Shopify, Salesforce Commerce Cloud, or similarSnowflake or data warehouse query optimization experienceMedia or high-traffic publishing platform backgroundExperience running or leading a multi-brand or multi-tenant web platformPrior startup experience where you owned significant platform surface area with a small teamAgile/Scrum experience in a distributed team environmentBenefitsSalary: $6,000 to $8,000 USD per monthPTO: 15 daysHolidays: Local or US holidays
