Senior Product Designer (d/f/m)

📍 Job Overview

Job Title: Senior Product Designer (d/f/m)

Company: Taxfix

Location: United Kingdom

Job Type: FULL_TIME

Category: Product Design / GTM Operations

Date Posted: 2026-06-25

Experience Level: 5+ Years

Remote Status: Fully Remote

🚀 Role Summary

• Full Loop Ownership: Drive product features from initial user problem identification through to shipped interface, minimizing handoffs and maximizing autonomy within a mission team. This aligns with modern GTM operational efficiency by streamlining the product development lifecycle.

• AI-Augmented Design: Leverage AI tools, including Claude Code, to accelerate exploration, prototyping, and development, while applying critical design taste and editorial judgment to ensure quality and user trust. This emphasizes the integration of AI in operational workflows.

• Outcome-Oriented Impact: Focus on measurable outcomes and key performance indicators (KPIs) that directly influence user experience and business goals, rather than solely on design deliverables. This is a core tenet of revenue and sales operations.

• Cross-Functional Stretch: Operate beyond traditional design boundaries, contributing to product strategy, engineering implementation (via AI coding tools), and user research to ensure a cohesive and efficient end-to-end product development process. This reflects a GTM operations mindset of breaking down silos.

📝 Enhancement Note: While the role is titled "Senior Product Designer," the description heavily emphasizes a "Builder" archetype that spans product, design, and engineering. This indicates a strong GTM operations focus on cross-functional efficiency and end-to-end ownership, moving beyond a siloed design function. The emphasis on AI and rapid experimentation also points to a need for operational agility and data-driven decision-making.

📈 Primary Responsibilities

• End-to-End Product Development: Take ownership of the full product lifecycle for the UK market, from defining user problems and writing briefs to designing flows, prototyping, and shipping interfaces with minimal external dependencies.

• Mission Team Integration: Plan and execute design activities within a dedicated mission team, ensuring alignment with quarterly OKRs and business objectives, and translating complex requirements into actionable design solutions.

• AI Tool Integration & Acceleration: Utilize AI tools, including Claude Code, to explore design concepts, build prototypes, and accelerate the development process, acting as the final editorial layer for AI-generated outputs.

• Rapid Experimentation & Deployment: Deploy experience-driven experiments directly into production to validate customer demand and justify engineering resource allocation, embracing a fast-paced, iterative approach.

• Design System Stewardship: Extend and contribute to the company's design system by identifying new patterns and use cases, ensuring consistency and scalability across the product suite.

• Detail-Oriented Craftsmanship: Focus on the critical final 10% of design work to ensure the product feels trustworthy and reliable, especially given the sensitive nature of tax-related services.

• Metric-Driven Performance: Measure personal and team success based on quantifiable impact on user metrics and business outcomes, rather than the volume of design assets produced.

• Proactive Communication & Feedback: Provide direct, candid feedback to all team members, regardless of seniority, and openly communicate blockers and challenges to ensure team velocity.

• Cross-Disciplinary Contribution: Actively engage in aspects of product management and engineering, such as reading API specifications and using AI coding tools to implement designs when more efficient than Figma.

📝 Enhancement Note: The responsibilities highlight a "Builder" role that is intrinsically linked to GTM operations by emphasizing speed, autonomy, and outcome-driven execution. The expectation to "stretch beyond design" and engage with engineering and product management implies a need for strong operational understanding of the entire go-to-market process, from ideation to customer acquisition and retention.

🎓 Skills & Qualifications

Education: While no specific degree is mandated, a strong portfolio demonstrating practical application of design principles and problem-solving is essential. Practical experience and demonstrable skills will be prioritized over formal education.

Experience: Minimum of 5+ years in a product design role, ideally within a product-centric organization, with a proven track record of shipping impactful user interfaces and driving measurable improvements in key metrics.

Required Skills:

• Product Design Craft: Deep expertise in visual design, interaction design, and user experience principles, with a strong portfolio showcasing shipped products and quantifiable results.
