About The Position
GenPeach AI is a product-driven research lab building vertical multimodal foundation models for hyper-realistic human generation in image and video – designed for emotionally resonant, human-centered AI experiences. Our goal is to create tools that supercharge human creativity rather than replace it. We train models from scratch using proprietary datasets at massive scale, novel architectures and training recipes, large GPU clusters, and tight product integration so research ships to users quickly. We are a deeply technical team of around 10 people. We’re advised by Directors from Google DeepMind and backed by leading AI-focused funds and angels from OpenAI, Meta AI, Microsoft AI, Project Prometheus, and Fal. Collectively, our team, advisors, and angels have contributed to models including Meta’s Imagine/MovieGen and foundation-model work behind OpenAI’s Sora, plus Google’s Veo and Gemini. You’ll join the research team working across image/video generation and multimodal understanding. You’ll work closely with other Research Engineers and Scientists, as well as Founders and help turn research into scalable training runs, strong evaluations, and production-ready systems. We’re hiring an AI Research Engineer to help build and scale GenPeach’s foundation models end-to-end – from implementing new model ideas and training recipes, to owning the parts of the training stack that determine quality and speed, to pushing models through production constraints. This is a hands-on, high-ownership role. You’ll write research-grade code that becomes production-critical.
Requirements
- Strong Python and PyTorch skills (4+ years of experience)
- Experience implementing and training deep learning models (generative models, VLMs, LLMs, vision/video, or adjacent)
- Solid understanding of training dynamics, optimization, and practical debugging
- Ability to drive projects end-to-end with minimal supervision
Nice To Haves
- Hands-on experience with diffusion/flow-based image or video generation, or large-scale generative modeling in adjacent domains
- Experience with distributed training at scale (multi-node) and performance tuning (throughput/memory)
- Experience building evaluation frameworks (offline metrics + human eval + regression tracking)
- Strong intuition for data quality and dataset/labeling tradeoffs for training and captioning
- Publications are a plus, but shipped impact and strong technical evidence matter more
Responsibilities
- Implement and iterate on image/video generative model ideas (architecture, losses, conditioning, sampling, pre-training, distillation, post-training)
- Own training performance end-to-end (distributed training, throughput, memory, stability, debugging scaling failure modes)
- Build the experimentation loop (evals, ablations, reproducibility tooling, reporting, decision hygiene)
- Build and improve VLMs for image/video captioning (data recipes, training strategies, model variants, evaluation)
- Run high-iteration research: read papers when useful, implement ideas, validate empirically
- Create captioning pipelines that improve generation training and product quality
- Partner with inference/product to ship under real constraints (latency, cost, reliability, rollout safety)
- Build demos and prototypes to showcase capabilities and accelerate iteration
Benefits
- competitive salary + meaningful equity (level-dependent)
- Visa sponsorship (where applicable); we’ll make a strong effort to relocate you to Switzerland or Poland if desired
- Remote-friendly: work fully remote, hybrid, or on-site from our hubs
- Regular offsites and in-person events to collaborate and connect
- Flexible PTO
