Job description

We are Berlin Bytes. As a creative software development and consulting agency, we help businesses navigate the complexities of the digital landscape and unlock lasting value. Together with our clients we design, build, and scale innovative digital solutions and enterprise applications that deliver tangible results.

The Opportunity

We’re building our freelance designer pool and are looking for an experienced Product Designer for web and mobile projects. This role is for someone with strong UX/UI skills who also brings product thinking, someone who can shape user experiences while considering business goals, product priorities, and technical feasibility.

This is not a full-time role and not tied to an immediate project. We are building a trusted pool of freelance collaborators for future project-based work. If timing and fit align, this can lead to repeated or longer-term collaboration.

Your Mission as a Product Designer

As a freelance Product Designer, you will help define and design digital products from early ideas through to implementation-ready designs. You will combine user-centred design with product thinking to create clear, useful, and well-crafted experiences.

What You Will Be Doing

• Help define problem spaces, user needs, value propositions, and product opportunities for digital products and services
• Design end-to-end user experiences for web and mobile applications, from early concepts and wireframes to polished interfaces
• Contribute to product discovery, user flows, product strategy, prototypes, and final UI
• Support feature definition and prioritisation with a product mindset
• Collaborate with stakeholders, product teams, and developers
• Create clear, implementation-ready designs and handoff materials
• Work within or contribute to design systems where needed

• Strong spoken and written English

Nice-to-Haves

• Experience in agency, consulting, or client-facing environments
• Experience with SaaS, enterprise, mobile, or AI-related products
• Workshop or discovery facilitation experience
