Senior Product Designer

Synthflow AI is a no-code platform for deploying voice AI agents that automate phone calls across contact center operations and business process outsourcing (BPO) at scale. We help mid-market and enterprise companies manage routine calls to save teams time and resources.

Our agents have already delivered measurable impact:

• Over 5 million hours of contact center operations saved
• 35% more calls answered compared to non-AI operators
• 45 million calls handled with a 99.9% uptime

Backed by Accel, Atlantic Labs, and Singular and trusted by over 1,000 customers, our growth leads an industry shift toward sophisticated and accessible conversational AI.

What You’Ll Do

• Own end-to-end product design for workflows, dev tooling, and AI agent experiences.
• Translate complex technical concepts (Prompting, APIs, Evals, workflows) into intuitive and delightful interfaces.
• Work side-by-side with founders, engineers, and product leaders to rapidly ship and iterate.
• Push projects forward with a bias towards action — no theory.
• Conduct lean user research, testing, and feedback loops with customers to validate design decisions.
• Shape and evolve our design system and product identity as we scale.
• 5+ years of product design experience, with ownership of shipped products from idea to production.

What We’Re Looking For

• Background in startups — ideally as an early or founding Product Designer (Seed → Series A+ growth journey).
• Technical fluency — you don’t shy away from JSON, APIs, traces, logs, and know how to design for technical users.
• Proven experience designing developer-facing tools, workflows, or automation or AI Agent products.
• Entrepreneurial mindset: comfortable with ambiguity, scrappy execution, and wearing multiple hats.
• Strong balance of UX, UI, and product thinking; portfolio that shows both craft and speed.

What We Offer:

• Autonomy at speed: High-ownership roles in a fast-moving startup.
• Cutting-edge technology: Work on what interests you most.
• Career growth: Scale your impact as the company grows.
• Rewarding package: Competitive pay, equity options, and comprehensive benefits that reflect your skills and experience.
