About HappyCo

HappyCo is a values-driven company where people can grow their careers and work with like-minded people, with no egos or politics. We offer a flexible, supportive culture.

Design Ownership & Impact

• Own a defined product area end-to-end, from problem framing and discovery through to delivery, measurement, and iteration
• Work backwards from real customer problems, developing a deep understanding of user workflows, constraints, and decision-making contexts
• Identify and prioritize high-leverage problems, articulating why they matter for customers, the business, and long-term product quality
• Translate complex, ambiguous problem spaces into clear hypotheses, design principles, and scalable solutions
• Design, test, and ship high-quality web experiences, including flows, information architecture, interaction models, and polished UI
• Apply strong systems thinking across workflows, roles, permissions, and data models to ensure solutions scale and remain coherent
• Make deliberate trade-offs between usability, speed, quality, and technical constraints, and clearly communicate those decisions
• Call out when technically impressive or elegant solutions are misaligned with customer value, usability, or business outcomes
• Measure the impact of your work using qualitative and quantitative signals, validate outcomes with customers where possible, and iterate based on what you learn

Customer Obsession & Insight

• Run timely, pragmatic research including interviews, usability testing, and lightweight validation loops as part of everyday product work
• Bring real customer context – quotes, workflows, edge cases, and observed behaviours – into product and design discussions
• Synthesize customer insights into clear patterns and themes, not just isolated findings
• Act as an evidence-backed voice for the customer in cross-functional conversations
• Create lightweight, repeatable ways for teams to stay close to customers, even when direct access is limited

AI & Emerging Interaction Design

• Design AI-assisted experiences that help users proactively explore data, surface insights, and make better decisions
• Shape agentic workflows, conversational interfaces, and voice-enabled interactions where they meaningfully improve outcomes
• Translate complex AI capabilities into understandable, controllable, and trustworthy user experiences
• Define appropriate guardrails, affordances, and fallbacks so AI-powered features remain usable and reliable

Collaboration & Craft

• Partner closely with Product Managers and Engineering Leads to shape problem definitions, scope work, and sequence delivery
• Collaborate with Engineers to ensure designs are feasible, performant, and thoughtfully implemented
• Work with Design Leadership to align on quality, product experience principles, and design standards
• Adhere to, uphold, and actively champion HappyCo's design system
