Overview

About Act Second

Act Second is a premier consulting and creative studio for a new generation of brand builders. Our expertise spans Creativity, Marketing, Digital, and Strategy, supporting both established clients and emerging ventures. We craft tailored marketing ecosystems that prioritize performance, automation, and brand impact—email marketing being a critical pillar of that strategy.

We are looking for a Developer with deep expertise in email marketing, specifically with hands-on experience building custom emails and automated flows in Klaviyo. This role will work across Act Second's agency clients and portfolio ventures, helping execute performance-driven email programs. You'll be responsible for building modular, responsive emails from scratch, optimizing flows, and supporting retention strategies through code-level execution.

Key Responsibilities

• Email Development: Build pixel-perfect, responsive HTML emails compatible across all major platforms and devices, primarily within the Klaviyo ecosystem
• Flow Setup: Design, build, and maintain automated flows in Klaviyo (welcome, abandoned cart, post-purchase, win-back, etc.) for multiple brands
• Template Management: Create reusable templates, modules, and design systems that allow for scalability across clients
• Platform Execution: Own email development and deployment in Klaviyo, including list segmentation, dynamic content, and testing
• A / B Testing & Optimization: Implement A / B tests on subject lines, layouts, and CTAs to drive engagement and conversion
• Collaboration: Work closely with strategists, designers, and content creators to ensure seamless integration between creative direction and technical execution
• Troubleshooting: Debug and resolve rendering issues across different clients and devices

Documentation: Maintain documentation for templates, flows, and deployment processes to ensure repeatability and efficiency.

Qualifications

• Proven experience coding and building custom HTML / CSS emails (not just drag-and-drop)
• 2+ years of hands-on experience working within Klaviyo, including flows, segments, and A / B testing
• Understanding of email development best practices (dark mode, fallbacks, accessibility, etc.)
• Familiarity with liquid logic and Klaviyo's templating language
• Strong attention to detail and ability to translate designs into clean, responsive code
• Comfortable working in a fast-paced environment with shifting priorities
• Fluent in English (mandatory)
• Remote working, we are based in Barcelona.

Preferred Qualifications

• Experience with other email platforms (Braze, Iterable, Mailchimp) is a plus
• Proficiency with Figma, and knowledge of Adobe XD for interpreting design specs
• Previous experience working in a performance marketing, creative agency, or e-commerce brand setting.

Benefits

• Competitive salary and growth opportunities
• Work across both agency and venture businesses with diverse challenges
• Creative autonomy and technical ownership of key retention channels
• Young, international team based in Barcelona
• Work with top-tier brands and ambitious startups in the US and Europe.
