Senior 3D & Motion Designer

About the role
SmartAC is a physical product that does invisible work. The challenge is making that work visible — showing homeowners and contractors what our sensors actually do, how they sit inside a home to provide this continuously visible data set, and why the intelligence behind them matters. That’s a 3D and motion problem, not just a graphic design problem.

We’re looking for a contracted 3D & Motion Designer to create product visuals, animated explainers, and marketing motion assets that bring our hardware and platform to life. You’ll work under the creative direction of our CMO and Head of Hardware Design and alongside our front-end engineering team, who will implement your work into scroll-based web experiences and interactive product pages.

What you’ll do
- Work with existing SmartAC hardware CAD models and design assets to create high-fidelity product renders, scenes, and animations with accurate materials, lighting, and real-world context. (mounted on HVAC equipment, inside a home environment).
- Ability to generate, modify or optimize 3D CAD geometry is a plus.
- Create animated product sequences: exploded views, sensor placement reveals, data-flow visualizations, and “how it works” loops for web, social, and sales materials.
- Produce marketing motion assets for hero sections, landing pages, social campaigns, and sales decks — delivering files optimized for web playback and handoff to engineering.
- Collaborate directly with front-end engineers to prepare assets for scroll-based web experiences and interactive product pages, including design handoffs in Figma and exported motion assets ready for implementation.
- Contribute to the evolution of SmartAC’s visual identity and brand system as it applies to 3D and motion — ensuring consistency across hardware renders, animations, and marketing materials.

What we’re looking for
- 4+ years of professional experience in motion design, rendering and product visualization for physical or hardware products (consumer electronics, IoT, wearables, jewelry, or similar).
- Professional proficiency in one or more industry-standard 3D and motion design platforms such as Cinema 4D, Blender, Maya, or similar.
- Experience with rendering tools including Redshift, Octane, V-ray, Arnold or Keyshot is a plus. We care more about the quality of motion, rendering, and storytelling than specific software.
- Strong working knowledge of Adobe Creative Suite (After Effects, Photoshop, Illustrator) for compositing, post-production, and asset delivery.
- Comfortable in Figma for design collaboration and engineering handoff — you’ll be working closely with a front-end team that builds from your designs.
- Demonstrated motion graphics ability: you understand timing, easing, and storytelling through movement — not just making things spin.
- Experience working cross-functionally with engineering, product, and leadership teams through iterative creative processes.
- Art direction sensibility — you can take creative direction well, but you also bring your own point of view to a brief.

Nice to have
- Experience with UX motion design — UI animations, micro-interactions, and product interface motion — is a strong plus.
- Experience adapting engineering or industrial design CAD assets into marketing-ready visualizations and animation workflows
- Sound design skills for animated explainers and marketing videos.
- Experience with real-time 3D or web-native formats (Three.js, Spline, Lottie) for interactive web experiences and familiarity with scroll-triggered animation frameworks or the ability to spec motion for engineers implementing them.
- Experience creating product prototypes to communicate product concepts to stakeholders or leadership.
- A portfolio that includes hardware or physical product visualization in real-world environments.
