Senior ML Platform Engineer

Hapiko and the Stickerbox Story
Hapiko a new part of the Spin Master family is the creator of Stickerbox an AI sticker printer for kids. A child holds a button says a unicorn riding a slice of pizza through space and seconds later a physical sticker prints out. This is powered by a proprietary generation pipeline that turns a childs idea into safe fun printed art in just a few seconds.

What will you work on
You arent just one of a dozen ML engineers lost in a Big Tech department. You will own the architecture and performance of the machine learning pipeline that powers Stickerbox scaling this technology to support a global product launch. This role is designed for a builder who wants to learn exactly how to launch and scale a physical AI product for kids from the ground up. You will make the foundational architectural decisions and translate product requirements into reality.

This is a hybrid role 3 days per week out of our Long Island City office.

• Own end-to-end latency from a kids voiced input to a physical printed sticker and the profiling to eliminate every bottleneck
• Design and manage model deployment versioning and rollback strategies for a fleet of consumer hardware devices
• Optimize batching caching and GPU utilization across image generation speech recognition and character models to keep the experience fast and affordable
• Conduct build-vs-buy analysis for hosting and inference architecture and lead any resulting migrations
• Design and maintain serving-side enforcement of product safety kid-safe compliance and automated character-fidelity checks
• Manage the queues autoscaling observability and release engineering that supports the ML generation path

What are your skills and experience

• Experience deploying and operating diffusion or similar generative ML models in production with real latency constraints
• Experience profiling a generation path to optimize for performance and cost
• End-to-end production ownership experience including deployment capacity planning observability and on-call support
• Advanced knowledge of ML infrastructure inference systems and production software architecture
• Experience translating product requirements into scalable technical solutions and roadmaps
