Transform Visual Models into Real-World Applications
We’re building AI systems for a global audience. We are living in an era of AI transition - this new project team will be focusing on building applications to enable more real world impact and highest usage for the world.
This role is a global role with remote working arrangement. You’ll work closely with regional teams across product, engineering, operations, infrastructure and data to build and scale impactful AI solutions.
Why This Role Matters
You’ll fine-tune state-of-the-art models, design evaluation frameworks, and bring AI features into production. Your work ensures our models are not only intelligent, but also safe, trustworthy, and impactful at scale.
What You’ll Do
Fine-tune & Adapt – Train and customize diffusion models (SDXL, Flux, Stable Diffusion variants) using LoRA, DreamBooth, and other parameter-efficient methods.
Curate Datasets – Build, clean, and annotate large-scale image datasets with captioning, tagging, and NSFW filtering for safe and aligned generation.
Evaluate & Align – Develop pipelines to measure fidelity, diversity, style adherence, and safety across generated outputs.
Optimize Performance – Apply GPU memory optimization, latent diffusion tricks, and distributed training for efficient scaling.
Deploy & Monitor – Ship diffusion-powered features into production with monitoring for drift, latency, and quality.
Collaborate & Deliver – Work with product and design to integrate generative vision capabilities into user experiences.
What Is It Like
Likes ownership and independence
Believe clarity comes from action - prototype, test, and iterate without waiting for perfect plans.
Stay calm and effective in startup chaos - shifting priorities and building from zero doesn’t faze you.
Bias for speed - you believe it’s better to deliver something valuable now than a perfect version much later.
See feedback and failure as part of growth - you’re here to level up.
Possess humility, hunger, and hustle, and lift others up as you go.
Requirements
Strong experience with diffusion models and generative vision (Stable Diffusion, SDXL, Flux, etc.).
Hands-on skills with DreamBooth, LoRA/QLoRA, and fine-tuning methods.
Proficiency with PyTorch (preferred).
Experience in dataset preparation (captioning, tagging, filtering, augmentation).
Knowledge of GPU optimization, latent diffusion, and efficient training techniques.
Strong foundations in software engineering, algorithms, and clean code practices.
Nice to Have
Prior work in style transfer, personalization, or multimodal generation.
Experience with safety alignment in generative vision (NSFW detection, adversarial testing).
Open-source contributions in diffusion or generative vision projects.
What You’ll Get
Flat structure & real ownership
Full involvement in direction and consensus decision making
Flexibility in work arrangement
High-impact role with visibility across product, data, and engineering
Top-of-market compensation and performance-based bonuses
Global exposure to product development
Lots of perks - housing rental subsidies, a quality company cafeteria, and overtime meals
Health, dental & vision insurance
Global travel insurance (for you & your dependents)
Unlimited, flexible time off
