We are seeking a senior frontend-focused software engineer to support scalable, dynamic email template systems. This role is best suited for a strong frontend engineer with modern React, TypeScript, and JavaScript experience who can also work deeply with reusable email components, Apache Velocity/VTL-style templates, responsive HTML/CSS, APIs, localization, and personalization at scale. This is not an email developer-first role.

The adecuado candidate has a strong software engineering foundation, frontend engineering depth, and the ability to build scalable, component-based solutions for dynamic, personalized email experiences.

Key Responsibilities Enterprise experience strongly preferred. Build and maintain scalable frontend and email template components using modern web development practices. Develop dynamic email templates using Apache Velocity/VTL-style macros such as #set, #if, #foreach, and #define. Compose reusable Velocity components and macros into full email templates.

Translate

Figma designs into modular, maintainable code. Work with shared design systems and reusable components instead of one-off hand-authored HTML. Determine when to extend an existing component versus building a new one.

Integrate user interfaces and email templates with backend platforms and API-driven data sources. Connect to, query, consume, and format internal or external API data for conditional, logic-driven dynamic emails. Build templates for scale, including 100+ locales, localized copy, dynamic data, per-recipient personalization, and array-based looping.

Hand-code responsive,



accessible HTML/CSS optimized for email client rendering limitations across Outlook, Gmail, and Apple Mail. Work fluently with Git, GitLab or GitHub, the command line, and modern IDE-based development workflows. Collaborate in environments using CI/CD pipelines, Infrastructure-as-Code tooling, and AWS primitives.

Qualifications Must-Have Skills Senior-level frontend or software engineering execution. Bachelor’s degree in Computer Science, Engineering, or a related field with at least 5 years of related experience, or Master’s degree with at least 3 years of related experience. Current or most recent role should likely be Software Engineer or Frontend Engineer with a frontend focus. Strong frontend development experience using React, TypeScript, and JavaScript.

Experience integrating frontend interfaces with backend platforms or services. Strong command of Apache Velocity, VTL, or Velocity-style macro templating. Hands-on experience with macros such as #set, #if, #foreach, and #define.

Experience composing components or macros into full email templates.

Experience working with scalable design systems and shared reusable components. Ability to build for personalization, localization, and dynamic data at scale. Proven experience consuming API data and using it in conditional,



logic-driven templates or user experiences. Advanced responsive HTML/CSS coding experience for email clients.

Experience building accessible email or frontend experiences. Familiarity with rendering limitations across Outlook, Gmail, and Apple Mail.

Strong

Git, command line, and IDE workflow skills.

Experience translating Figma designs into modular code. Working knowledge of AWS primitives such as compute, storage, networking, and IAM. Exposure to Infrastructure-as-Code tooling such as Terraform.

Experience with CI/CD pipelines such as GitLab CI. Nice-to-Have Skills Practical experience using AI-assisted development tools such as Cursor, Windsurf, Claude, Claude Code, or AI-driven code fixes. Prior exposure to component internationalization or localization frameworks. Prior experience with email-specific frontend systems or dynamic email platforms.
