Job description

Hey, we're BRAINR.

Our mission is to build the intelligent brain for every food factory, with the only AI powered factory operating system for the food industry, bringing together machines, sensors, software, and people.

Profitable from day one, we've recently secured a record breaking €12.5M Seed Round, the largest in Portugal's history, to take our mission global. And we're getting there, because today over 30% of all meat production in Portugal is already managed by BRAINR.

Along the way, we've been recognized as the Best Factory Digitization Solution at Food 4 Future in Spain, selected for EUROPA's 100 most promising startups, and named a Top Cloud Based MES Solution by Manufacturing Tech Insights.

What sets us apart isn't just the tech. It's the people. Our leadership team combines deep industry know how with world class tech expertise, giving you the chance to learn and grow faster than anywhere else.

The mission is massive. The ambition is real. And we need talent like you to bring our vision to every food factory on earth.

The Challenge

We're looking for a UX/UI Designer to shape intuitive, effective experiences across BRAINR's AI-powered factory operating system. You'll turn complex industrial workflows and user needs into clear, accessible interfaces that help people across food factories make confident, informed decisions.

This is a hands‑on product design role at the intersection of user research, interaction design, visual design, and technology. You'll work closely with Product, Engineering, and Customer Success, learning from factory teams and translating real‑world challenges into thoughtful digital experiences.

You'll take ownership of well‑defined features, with guidance from our Design Leader on more complex design challenges. As you deepen your understanding of our product and users, you'll have opportunities to grow your skills and take on broader responsibilities.

This role is based at our headquarters in Leiria, Portugal.

What You'll Own

• Design well‑defined features from understanding requirements through to delivery, exploring solutions and refining them with Product, Engineering, and the Design Lead.
• Create user flows, wireframes, interactive prototypes, and high‑fidelity UI designs in Figma for responsive web and mobile experiences.
• Help translate industrial workflows into clear, intuitive interfaces, working with the team to understand factory operations and user needs.
• Participate in user research, usability testing, and feedback sessions, applying findings to improve your designs.
• Work closely with developers to understand technical constraints, communicate design intent, and review implementation quality.
• Use and contribute to BRAINR's design system and reusable components, helping keep product experiences consistent.
• Participate in design reviews, explain your design decisions, and give and incorporate constructive feedback.
• Keep developing your craft through feedback, team learning sessions, and exploration of relevant design practices and tools.

What Success Looks Like

• The features you work on help factory teams complete their tasks more clearly and efficiently.
• Your designs are thoughtful, consistent with the design system, and ready for implementation.
• You use user feedback and design reviews to improve your work and explain the reasoning behind your decisions.
• You collaborate effectively with Product and Engineering, following your designs through implementation.
• You build confidence and autonomy as you learn more about our product, users, and industrial workflows.

Minimum Requirements

You may be a great fit if you have:

• 4+ years of experience in UX/UI, product design, or interaction design for digital products.
• A portfolio showing your design process, thoughtful UX decisions, clear UI, and examples of responsive design, with your contribution to each project explained.
• Proficiency with Figma, including user flows, wireframes, interactive prototypes, and high‑fidelity UI designs ready for implementation.
• A solid foundation in user‑centered design, interaction and visual design, usability, and accessibility.
• Hands‑on experience with user research or usability testing, and the ability to apply findings to design decisions.
• Experience using design systems and reusable components.
• An understanding of technical constraints and how design decisions affect development.
• The ability to structure information clearly and a curiosity for understanding complex workflows and data‑rich interfaces.
• Collaborative communication skills, openness to feedback, and the ability to explain your design decisions.
• A curious mindset and motivation to keep learning and improving your craft.
• Fluency in English, spoken and written.

Bonus Points

• Experience designing B2B SaaS products, enterprise software, or operational tools.
• Familiarity with food manufacturing or other complex industrial environments.
• Experience with data visualization, dashboards, mobile experiences, or AI‑powered products.
• Knowledge of front‑end development concepts such as HTML and CSS.
