AI/ML and Workflow Engineer – Generative AI (Founding Team)

I'm the founder of HeartStamp, a seed-stage funded startup. We're building a generative AI platform for personalized digital expression by combining cutting-edge models, LoRA customization, and a marketplace to turn creative intent into beautifully rendered digital content and high-fidelity, print-ready media. We are launching in the USA, Canada, and UK in Q1 2026, with plans for rapid worldwide expansion soon after.

We're hiring for a foundational *Freelance AI Workflow Engineer* to help us launch our MVP. You'll work closely with our Tech Lead to design and optimize our production pipelines using ComfyUI, Stable Diffusion (SD3.5/SDXL), LoRA, and TensorRT. A key part of the role will also be helping us define requirements for, interview, and onboard our initial prompt engineering team. This isn't just a freelance gig; it's a foundational, co-founding opportunity. As our first external engineer, you'll work directly with the founding team and have a clear path to a full-time, co-founder role with a significant equity stake.

Given your expertise, I thought it could be a great fit. If you're open to new projects, I'd love to chat and share more details. You can reach me here, on Telegram at *@phoenixonego*, or via email at *admin@heartstamp.com*.
