Graphic Designer  – Email Marketing Agency

Full-time · 40 hours/week · Remote-friendly

Position Overview

We are looking for a highly skilled and creative Graphic Designer to join our email marketing agency. In this role you will be responsible for two equally important things: independently designing high-converting email campaigns and landing pages in Figma based on detailed briefings, and independently reviewing email designs created by other designers in our team — evaluating their work, writing precise revision notes per brand, and approving final versions for delivery.

You will work across our diverse portfolio of e-commerce clients, with a strong focus on visual quality, conversion-driven design, and brand consistency. We expect a sharp eye for spacing, hierarchy, and what actually makes advertising creative work — not just designs that look nice, but designs that perform.

Key Responsibilities

1. Email Campaign Design (Figma)

• Independently translate detailed briefings into visually striking, on-brand email designs in Figma.
• Build campaigns that are not only beautiful but optimized for clarity, hierarchy, and conversion across desktop and mobile email clients.
• Maintain pixel-level consistency with each brand's visual identity, components, and design system.

2. Design Review & Revision Management

• Independently review email drafts produced by other graphic designers across all client brands.
• Evaluate work against brand guidelines, performance principles, and our internal quality standards.
• Document clear, structured, actionable revision notes per brand — so that the responsible designer can implement changes without ambiguity.
• Approve and release final designs once they meet our quality bar.

3. Landing Page Design

• Design conversion-focused landing pages that complement email campaigns: visual hierarchy, focal points, CTA placement, and on-brand storytelling.
• Ensure landing pages and emails feel like a single coherent experience for the end customer.

4. Photoshop & Asset Production

• Use Photoshop confidently for retouching, compositing, image preparation, and creative asset production.
• Optimize all visuals for email delivery (file size, format, resolution).

5. AI-Powered Workflow

• Actively use AI tools (Claude in particular) in your daily workflow — for ideation, briefing analysis, copy iteration, asset preparation, and quality checks.
• Stay curious and current. AI tooling is evolving fast, and we expect every team member to evolve with it. Willingness to experiment with new AI workflows is essential.

Required Skills & Experience

• Excellent skills — in landing page design and graphic design — strong portfolio is mandatory.
• Deep understanding — of spacing, white space, hierarchy, contrast, focal points, and what makes advertising creative actually work. Not just aesthetics — effectiveness.
• Advanced — Figma skills — collaborative design, components, auto-layout, design system management, prototyping.
• Strong — Adobe Photoshop skills for image editing, retouching, and asset preparation.
• Demonstrated — ability to evaluate other designers' work, articulate what is and isn't working, and write clear revision notes.
• Comfort — with AI tools (Claude or equivalent) and willingness to integrate them deeply into your daily creative workflow.
• Excellent — written and spoken English. This is a hard requirement — all internal and client communication runs in English.

Key Qualities We Look For

• Reliability — You hit deadlines and deliver consistent quality without supervision.
• Communication — You are responsive over WhatsApp and able to communicate fast and clearly in a small, high-velocity team.
• Constructive critique — You can give feedback to peers that is specific, kind, and actionable — and take feedback the same way.
• Creativity — You bring fresh visual ideas while respecting brand guidelines.
• Process discipline — You can work confidently inside our SOPs but also know when to push for a stronger creative solution.

Nice to Have

• German language skills — helpful for communication with parts of our team and a portion of our client base, but absolutely not required.
• Prior experience designing for Klaviyo or similar ESP environments.
• Experience working in an e-commerce / D2C context.

Working Environment

This is a full-time position (40 hours per week) in a fast-paced agency environment. You will work closely with our founders, account managers, and other designers across roughly 50 active client brands. We value initiative, ownership, and people who actually want to get better — both as designers and at using the tools (including AI) that compound their craft.

About us

We are a leading German email marketing agency specialized in tailored solutions for online shops. Our mission is to grow our clients' customer retention and revenue through professionally designed, data-driven email campaigns built primarily in Klaviyo. We foster a collaborative, supportive environment where creativity and adherence to proven processes are valued equally.

How to Apply

Send your CV and a portfolio that showcases email design, landing page design, and any work where the result was measurably effective (not just visually polished). Tell us briefly how you currently use AI in your design workflow — that part matters to us.
