Senior Product Designer

Synthflow AI
Full-time

๐Ÿ“ Job Overview

Job Title: Senior Product Designer

Company: Synthflow AI

Location: Berlin, Germany

Job Type: FULL_TIME

Category: Product Design / UX/UI Operations

Date Posted: 2025-09-23

Experience Level: Senior (5+ years)

Remote Status: On-site (with potential for remote flexibility in Germany)

๐Ÿš€ Role Summary

This Senior Product Designer role at Synthflow AI focuses on the end-to-end design of their no-code platform for deploying voice AI agents. The position requires a strong blend of UX, UI, and product thinking, with a particular emphasis on translating complex technical concepts into intuitive interfaces for both end-users and developers. The designer will be instrumental in shaping the user experience of workflows, developer tooling, and AI agent interactions, working closely with founders and engineering teams in a fast-paced startup environment. Success in this role hinges on a proactive, action-oriented approach, leveraging lean user research, and contributing to the evolution of the company's design system and product identity.

๐Ÿ“ Enhancement Note: While the job is listed as "On-site" in Berlin, the company operates in a startup environment and the description emphasizes a "bias towards action" and "scrappy execution." This suggests potential flexibility for the right candidate, especially if they are based in Germany and can demonstrate strong remote work capabilities and a commitment to collaborative, in-person sprints or key meetings. The "location_requirements_raw" specifying "Germany" further supports this potential flexibility for candidates within the country.

๐Ÿ“ˆ Primary Responsibilities

  • End-to-End Product Design Ownership: Lead the complete design lifecycle for key platform areas, including user workflows, developer tools, and the interfaces for AI agent interactions, ensuring a cohesive and intuitive user experience.

  • Complex Concept Translation: Deconstruct and translate intricate technical concepts such as prompt engineering, API integrations, evaluation metrics, and workflow automation into user-friendly and visually appealing interfaces that cater to both technical and non-technical users.

  • Cross-functional Collaboration: Work collaboratively and directly with founders, product managers, and engineers to rapidly iterate on designs, ensuring alignment with business objectives and technical feasibility.

  • Customer-Centric Design: Conduct lean user research, usability testing, and gather direct customer feedback to validate design decisions, ensuring the product meets market needs and user expectations.

  • Design System Development: Contribute to and evolve the company's design system, ensuring consistency, scalability, and efficiency across all product touchpoints, and helping to define the overall product identity.

  • Rapid Prototyping & Iteration: Champion a "bias towards action" by quickly prototyping and iterating on designs based on user feedback and market opportunities, focusing on tangible outcomes rather than theoretical approaches.

๐Ÿ“ Enhancement Note: The responsibilities highlight a strong focus on "developer-facing tools" and "AI agent experiences," which implies a need for the designer to deeply understand the technical user's journey and pain points. This requires not just UI/UX skills but also a degree of technical fluency to design effective solutions for complex technical workflows.

๐ŸŽ“ Skills & Qualifications

Education: A Bachelor's degree in Design, Human-Computer Interaction (HCI), Computer Science, or a related field is typically expected, though equivalent practical experience is highly valued in startup environments.

Experience: A minimum of 5 years of dedicated product design experience, with a proven track record of owning and successfully shipping products from initial concept through to production. Experience as an early or founding Product Designer in a startup environment, particularly during Seed to Series A+ growth phases, is strongly preferred.

Required Skills:

  • Product Design Expertise: Demonstrable end-to-end product design experience, including user research, wireframing, prototyping, and high-fidelity UI design.

  • User Experience (UX) & User Interface (UI) Craft: Strong command of UX principles and UI design best practices, with a portfolio showcasing a balance of both strategic thinking and visual execution.

  • Technical Fluency: Comfort and proficiency in understanding and designing for technical users, including familiarity with concepts like JSON, APIs, traces, logs, and developer workflows.

  • Design System Development: Experience in creating, maintaining, or contributing to design systems to ensure product consistency and scalability.

  • Entrepreneurial Mindset: A proactive, self-starter attitude with comfort in ambiguous environments, a scrappy approach to execution, and a willingness to wear multiple hats.

  • Collaboration & Communication: Excellent communication and interpersonal skills, with the ability to work effectively alongside founders, engineers, and product leaders.

Preferred Skills:

  • Developer Tooling Design: Specific experience designing interfaces for developer-facing tools, platforms, or workflows.

  • Automation & AI Product Design: Experience designing products within the automation or AI agent space, understanding the unique challenges and opportunities in these domains.

  • No-Code Platform Design: Familiarity or experience designing for no-code or low-code platforms.

  • Rapid Prototyping Tools: Proficiency with tools like Figma, Sketch, Adobe Creative Suite, InVision, or similar for rapid prototyping and high-fidelity design.

  • Agile Methodologies: Experience working within agile development frameworks.

๐Ÿ“ Enhancement Note: The requirement for "technical fluency" and designing for "developer-facing tools" suggests that candidates with a background in designing for SaaS platforms, developer tools, or complex backend systems will have a significant advantage. The portfolio should explicitly showcase projects demonstrating an understanding of technical user needs and workflows.

๐Ÿ“Š Process & Systems Portfolio Requirements

Portfolio Essentials:

  • End-to-End Case Studies: Showcase at least 2-3 comprehensive case studies detailing your involvement in shipping products from conception to launch, highlighting your role in problem definition, user research, ideation, design execution, and iteration.
