Job description

About the role

We're looking for a Senior Product Designer to join us on a 12-month fixed-term engagement, leading design across Sonder's member experience. Reporting to our CPTO, you'll take work from early discovery through to shipped, polished product, working closely with Product and Engineering day to day. The bulk of the role sits on mobile, though you'll bring range and craft across devices and platforms.

Must-haves

• 5+ years of senior or staff-level product design experience.
• A strong portfolio showing full-stack product design, from discovery through to shipped product, with particularly strong mobile interaction craft and visual polish.
• Design system experience — comfortable extending what already exists with good judgement, and helping build out new parts from the ground up.
• Genuine curiosity about AI tools and how they can sharpen your design process.
• Excellent design communication — confident presenting your thinking to a range of audiences, from engineering partners through to leadership.
• Comfortable moving between near‑term, ship‑ready work and longer‑range vision work as priorities shift.

Nice‑to‑haves

• Experience as a design lead in a fast‑moving startup environment.
• Experience building a design system from the ground up, not just extending one.
• Experience embedding AI tools directly into your day‑to‑day design process.
• Experience designing in regulated, high‑trust or health and safety‑adjacent spaces, working with clinical, safety or trust and safety stakeholders.

Why join Sonder?

• Hybrid and flexible working environment. Enjoy the perfect balance of in‑office collaboration and work from home flexibility, empowering you to optimise your productivity and work‑life balance.
• Our employees and their families get free access to the Sonder app with 24/7 support.
• Paid parental leave with an attractive return to work policy, 12 weeks for Primary Carers and 4 weeks for Secondary Carers, plus our Primary Carers return to work at 80% for the first 3 months at full pay.
• True AI Native organisation with access to Claude, Gemini and other tools to encourage you to experiment, automate and get those real efficiency gains, no matter the role.
• 2 days of study leave to invest in your professional growth.
• Salary Packaging and novated leasing.
• Access $250 annually to a fund to invest in your wellbeing, empowering you to choose the support that best fits your needs.
• Free coffee.
• Dog‑friendly office in our Sydney HQ.
• Volunteer leave. 2 days per year to participate in meaningful causes and contribute back to the community.
