Join to apply for the Junior Graphic Designer role at 15 Marketing Ltd.

We’re part of Super Group, the NYSE-listed digital gaming company behind some of the world’s leading Sports and iGaming brands.

At 15 Marketing, our vision is to deliver a thrilling and engaging gaming experience through best-in-class products, wherever we operate. Our mission is to create an online casino experience that excites every player – driven by intelligence, personalisation, and a team that takes pride in what we build.

We bring this to life every day through the behaviours we live by:

Challenges are part of our journey, and we embrace them with curiosity, persistence, and a commitment to learning and growth. We may not have all the answers upfront, but we’re dedicated to improving with every experience.
We communicate early, clearly, and often. Whether it’s a project update, an idea, or a concern—nothing gets left unsaid. Open, transparent conversations build trust and fuel high performance because when communication flows, everything runs smoother.
We challenge ideas, not people. We tackle tough topics, welcome honest feedback, and speak our truth—even when it’s uncomfortable—because innovation thrives when everyone feels empowered to contribute.
We’re building something meaningful, and we believe that’s worth enjoying. We take our work seriously, but not ourselves. We celebrate wins, support each other through challenges, and create a space where everyone can grow and thrive together.
We never settle for “good enough.” From the quality of our campaigns to the clarity of our thinking and how we support customers and colleagues, we always strive for excellence.
Trust is the foundation of everything we do. That means being honest, owning our actions, delivering on our promises, and standing by each other—even when it’s tough.

Who we’re looking for

We are seeking a creative and detail‑oriented Junior Designer to help bring our brand and campaigns to life across marketing channels. You will support the development of high‑quality design assets, ensuring consistency with brand guidelines while contributing fresh ideas and creative thinking. Working closely with senior designers and marketing teams, you’ll turn concepts into engaging visuals that elevate our brand presence and deliver impactful experiences.

What you’ll be doing

As part of your role, your responsibilities will include:

Assisting in producing digital design assets including web banners, email creatives, social media graphics, display ads, and in‑product visuals.
Support the design and development of brand identity materials (logos, typography, colour palettes, templates, etc.).
Work closely with senior designers and marketing teams to bring creative concepts to life.
Ensure all creative output is consistent with brand guidelines and compliant with industry/regulatory standards.
Prepare assets for development and delivery (optimising files, resizing, formatting).
Contribute fresh ideas and creative input in brainstorms, workshops, and campaign planning sessions.
Maintain an organised library of assets and files to support wider business use.
Stay up to date with design trends, digital formats, and new creative tools.

This job description is not intended to be an exhaustive list of responsibilities. You may be required to complete other reasonable duties in order to achieve business objectives.

Essential skills you’ll bring to the table

0–2 years’ experience in a design role (agency, in‑house, or freelance).
Strong portfolio showcasing digital and/or brand design work.
Basic HTML/CSS skills to support email builds and digital campaign assets.
Proficiency in Adobe Creative Suite (Photoshop, Illustrator, InDesign, After Effects); knowledge of Figma or similar is a plus.
Basic understanding of design principles: layout, typography, colour theory, and responsive design.
Good attention to detail and ability to follow brand guidelines.
Strong communication skills and willingness to take feedback.
Organised, proactive, and able to manage multiple tasks in a deadline‑driven environment.

Desirable skills you’ve got up your sleeve

Experience in the i‑gaming industry.
