Requirements
Bachelor’s degree in Computer Science, Engineering, or a related field with 4+ years of related experience, OR a Master’s degree with 3+ years of experience. A proven track record in front-end development. Your most recent role should ideally be as a Software Engineer with a front-end focus. Modern Web Frameworks: Strong front-end development experience using modern web technologies (React is highly prioritized, TypeScript, JavaScript), and experience integrating user interfaces with backend platforms. Template Engines: Strong command of Apache Velocity (VTL), including Macros (#set, #if, #foreach, #define), and a deep understanding of how Velocity components/macros compose into full email templates. Email Engineering: Mastery of hand-coding highly responsive, accessible HTML/CSS optimized to bypass the rendering limitations of tough email clients (Outlook, Gmail, Apple Mail). API Integration: Proven experience connecting to, querying, and consuming data from various internal/external APIs, and formatting that data into conditional, logic-driven dynamic emails. Scale & Personalization: Experience authoring templates once and launching them to 100+ locales, handling localized copy and second-level personalization (per-recipient jobs, dynamic data, looping through arrays). Version Control & Environment: Fluent with Git (GitLab/GitHub), the command line, and modern IDEs (Cursor, Windsurf, VS Code). Design Tools: Figma (specifically translating designs into modular code components). Cloud Infrastructure: AWS primitives (compute, storage, networking, IAM). DevOps / CI-CD: Experience with Infrastructure-as-Code tooling (e.g., Terraform) and CI/CD pipelines (e.g., GitLab CI).
