I'm the founder of a stealth-stage, seed-funded startup (👀 HeartStamp is the codename). We're building a generative AI platform for personalized digital and tactile expression using an architecture that combines:

• Flux Kontext via FAL.ai for image generation
• Runway (Gen‑4) for motion & video
• Modular fallback via Stable Diffusion / ComfyUI
• A growing creator community for styling, moderation, and prompt intelligence

We're launching an MVP targeting the U.S., Canada, and UK by Q2 2026 and are now hiring for a foundational AI Workflow Engineer to help lead our infrastructure and pipeline buildout.

This is a contract-to-hire position (3–6 months), with a clear, immediate path to a full-time founding team role + equity stake (0.5–2%).

🔧 You’ll work on:

• Orchestrating API-based image/video generation using FAL.ai + Runway
• Designing prompt-personalized pipelines using dynamic input parameters and fallback logic
• Building Docker-based routing systems for modular, multi-model workflows
• Collaborating with our Prompt Engineering & Moderation team (which you’ll help build)
• Shipping a production-ready backend that balances latency, fidelity, and creative control

✅ You might be a fit if you have:

• 3+ years building AI workflows or composable model pipelines
• Experience integrating endpoints like FAL.ai, Runway, Replicate, etc.
• Strong Python + JSON fluency for backend workflow logic
• Docker experience; familiarity with container-based routing, queues, webhooks
• Comfort balancing prompt structure, creative intent, and infrastructure performance
• Bonus: exposure to ComfyUI, sampling/schedulers (DPM++, Karras), LoRA triggers, or image → PDF
• Great async communication skills — this is a small, distributed, trust-driven team

🛠 Tech Stack (for now):

• Flux via FAL.ai endpoints
• Runway Gen‑4 API
• Python, Docker, JSON-based prompt routing
• (Optional) fallback SDXL + ComfyUI
• Prompt meta-layer for credit-based personalization + moderation

🧩 What You’ll Influence:

• Our entire generative pipeline
• Our creator-facing workflow systems
• Our Prompt Engineering & Moderation pod
• And potentially, the future of how people visually express emotion at scale

📍 Logistics

• Remote (U.S. time zones preferred)
• Contract-to-hire (3–6 months → full-time)
• Compensation: $80–$120/hr → $170–210K full-time + equity
• Timeline: Start ASAP, MVP by Q2 2026
• Not a "freelance gig" — this is an early-team founder-tier opportunity
