Junior AI Engineer developing agentic systems for AI fintech solutions in healthcare. Collaborating in agile team to create impactful and innovative AI applications.
About the role
- AI Engineer specializing in training audio and multimodal models for AI safety. Work at White Circle, focusing on production-ready solutions for AI systems.
Responsibilities
- Train and fine-tune large-scale audio and multimodal models from scratch and from pretrained checkpoints
- Design and run experiments: architecture changes, data mixes, training recipes
- Build and maintain audio data pipelines — from raw recordings to training-ready datasets
- Optimize models for production: quantization, distillation, streaming inference
- Deploy models end-to-end: from research checkpoint to low-latency serving
- Collaborate with research to turn experimental ideas into shippable features
- Define evaluation metrics and benchmarks that actually matter for the product
Requirements
- 3+ years of experience training large-scale deep learning models in audio, speech, or acoustic domains
- Strong hands-on experience with PyTorch, distributed training (DeepSpeed, FSDP, or similar)
- Familiarity with audio/speech architectures (Audio Qwen, Whisper, HuBERT, Conformer, or similar)
- Experience with vision-language and multimodal architectures (Audio Flamingo, Omni Qwen, or similar)
- Track record of shipping models to production: you've hit latency targets, not just accuracy benchmarks
- Comfortable working with large-scale audio data pipelines: preprocessing, augmentation, dataset curation
- Understanding of audio signal processing fundamentals: spectrograms, mel features, noise reduction
- Experience with SFT, DPO, GRPO or other alignment techniques — ideally in multimodal setting
- Strong engineering fundamentals: clean code, version control, testing, documentation
Benefits
- 20 days of paid vacation
- Work from Paris (hybrid) + relocation package
- Best medical insurance in France
- All the hardware, tools, and services you need
- Covered subscriptions for AI agents and IDEs
- Team off-sites twice a year: we’ve recently been to the Alps and to Saint-Tropez
