Date Posted: August 30, 2026

Experience Level: Mid-Level (2-5 years)

Remote Status: Remote OK (with office options in Leiria and Braga)

🚀 Role Summary

• Design intuitive and visually appealing user experiences for Leadzai's product, focusing on optimizing the user journey and enhancing user satisfaction.

• Conduct comprehensive user research, leveraging both quantitative data analysis and qualitative methods like surveys, interviews, and usability testing to identify and solve user pain points.

• Develop wireframes, prototypes, and user interfaces (UI) that are visually engaging, align with brand identity, and meet business objectives while ensuring technical feasibility.

📝 Enhancement Note: This role is positioned within a "scale-up" environment, implying a need for adaptability, a strong work ethic, and the ability to contribute to a rapidly evolving product and team. The emphasis on "hard work," "long hours," and "going the extra mile" suggests a demanding but potentially rewarding culture for high-achievers. The "Work From Where You Want" policy, with office options, offers flexibility but requires candidates to have adequate remote working conditions.

📈 Primary Responsibilities

• Own and execute all qualitative data gathering processes, ensuring accurate problem definition and the development of effective solutions.

• Collaborate with Product Managers and engineers to define critical success metrics and product KPIs, and continuously monitor initiative progress against these benchmarks to ensure strategic alignment.

• Create detailed wireframes and interactive prototypes to visualize and communicate complex user flows and design concepts effectively to cross-functional teams.

• Design visually appealing, intuitive, and on-brand user interfaces (UI) that enhance usability and user engagement across all product touchpoints.

• Develop sophisticated interaction designs, including animations and transitions, to create a seamless and engaging user experience, ensuring consistency across the product.

• Partner with Product Managers, engineers, and other stakeholders to ensure design decisions are aligned with overarching product goals, business objectives, and technical constraints.

• Actively solicit, interpret, and incorporate feedback from team members, stakeholders, and end-users throughout the entire design lifecycle to drive continuous improvement.

• Contribute to the evolution of the product's design system and ensure adherence to established UI/UX patterns and brand guidelines.

📝 Enhancement Note: The responsibilities highlight a holistic product design approach, encompassing research, ideation, prototyping, UI design, and collaboration. The specific mention of "defining success metrics" and "shaping our product's KPIs" points to a data-informed design process crucial for a product-led growth company. The need to "solve the right problem in the right way" emphasizes strategic thinking beyond just aesthetics.

🎓 Skills & Qualifications

Education:

• While no specific degree is mandated, a Bachelor's degree in Design, Human-Computer Interaction (HCI), Computer Science, or a related field is often preferred for roles requiring in-depth user research and interaction design principles.

• Proficiency in user research methodologies, including quantitative data analysis and qualitative techniques (surveys, interviews, usability testing).

• Expertise in wireframing and prototyping tools (e.g., Figma, Sketch, Adobe XD) to create high-fidelity mockups and interactive prototypes.

• Strong User Interface (UI) design skills, with a keen eye for visual aesthetics, layout, typography, and color theory, ensuring brand consistency.

• Skilled in Interaction Design, capable of defining user flows, microinteractions, and transitions that enhance usability and engagement.

• Understanding of front-end development principles (HTML, CSS, JavaScript) to facilitate better collaboration with engineers.

• Experience in SaaS product design.

📝 Enhancement Note: The requirement for "3 years of experience in a web product design team" is clear, but the emphasis on "soft skills" like a strong work ethic, willingness to go the extra mile, and autonomy suggests that cultural fit and drive are as critical as technical proficiency for this scale-up environment. The "Knowledge of the Digital Marketing Business" is a key differentiator, implying that understanding the context of Leadzai's product is essential.

📊 Process & Systems Portfolio Requirements

Portfolio Essentials:

• A curated portfolio showcasing a minimum of 3 distinct web product design projects, demonstrating a clear progression from problem identification through to final design solution.
