Senior Product Designer (Part-Time Contractor)

Overview

Kantata is building modern software for the professional services industry. We are seeking a contract Senior Product Designer for a part-time engagement to execute high-impact, project-level design tasks within specific product workstreams.

This role is highly tactical and focused on execution. You will step in to deliver polished, end-to-end design solutions for targeted feature sets, with an immediate focus on our Financial Management and emerging Agentic Platform areas.

• Role Type: Part-time Contract (approx. 15–20 hours/week)

• Duration: 3 to 6 months (with potential for extension)

• Location: Remote

The Role

• Execute Targeted Workstreams: Deliver high-fidelity, spec-ready designs for defined features from user flow to final polish.

• Partner for Execution: Work closely with PMs and Engineering to translate pre-defined project requirements into functional, scalable solutions.

• Apply Existing Design Systems: Implement and leverage our established design system patterns to ensure consistency across your assigned product areas.

What You’ll Do

Project Execution

• Deliver Complex Workflows: Design highly functional, net-new AI-driven workflows and improve targeted core product flows.

• Build Spec-Ready UI: Create clear, comprehensive interaction models, UI states, edge cases, and handoff-ready specifications.

• Apply Design System Patterns: Use, adapt, and implement our existing Figma design system components efficiently without needing to rebuild or re-architect the system.

Collaboration & Efficiency

• Engage with Product & Engineering: Collaborate closely with PMs and Engineers to rapidly resolve implementation details and edge cases.

• Operate with Autonomy: Take a hands-on, self-directed approach to completing project deliverables with minimal oversight.

• Move with Velocity: Focus on execution and delivery speed while maintaining a high standard of visual and interaction quality.

Core Capabilities & Hard Skills

Interaction Design (Critical)

• Strong command of UI states, complex multi-step workflows, and edge cases.

• Deep expertise in mapping clear user intent to precise system responses.

Information Architecture

• Ability to organize complex, data-dense features into clear, intuitive hierarchies.

• Expertise in structured navigation and mapping conceptual workflow models.

System Application (Practical Systems Thinking)

• Ability to quickly master and work within an established, highly complex product ecosystem.

• Skill in identifying and utilizing existing UI patterns to solve new design challenges.

Execution-Focused Communication

• Ability to clearly present design solutions and justify design decisions based on interaction best practices.

Experience & Tools

• Strong portfolio demonstrating execution of complex B2B SaaS, data-dense, or platform products.

• Advanced proficiency in Figma, with a strong background in utilizing established component libraries.

• Familiarity with modern frontend concepts (React, components) to ensure seamless engineering handoffs.

• Direct experience designing user interfaces for AI workflows (understanding deterministic vs. probabilistic system behavior).

• Experience working in high-velocity, contract, or agency environments where rapid onboarding and execution are required.

Compensation

• Hourly Rate: Competitive hourly rate, commensurate with senior-level contract experience.

• Flexibility: Flexible, asynchronous-friendly working hours.
