ОписаниеLabhouse is a Barcelona-based startup studio building AI-powered mobile apps used by hundreds of thousands of people worldwide. Our products — including Invoice Fly and Summary AI — are designed to make everyday tasks faster, smarter, and simpler through a subscription model that puts the user first. At Labhouse, AI is not a feature — it's the core of what we build. As our AI Engineer, you will own the development, fine-tuning, and productionization of the models that make our apps work at a high level of accuracy and performance.Задачи Research, design, and train models suited to the specific needs of our productsFine-tune existing open-source and foundation models to maximize accuracy and performanceOwn the full model lifecycle: data curation, experimentation, evaluation, and production deploymentCollaborate with mobile and backend engineers to integrate models directly into our appsDefine and track the metrics that drive quality — and continuously push them in the right direction ТребованияWe're looking for candidates with a degree in Computer Science, Electrical Engineering, Mathematics, Physics, or a related technical field. Hands-on experience training or fine-tuning deep learning models that are used in production. Strong Python skills and experience with ML frameworks (Py Torch or JAX preferred) Comfort with the full model development cycle: data pipelines, experiment tracking, evaluation, deployment and scaling.



Solid understanding of modern model architectures and when to apply them Ability to work autonomously, make decisions under uncertainty, and ship without waiting for perfect conditions You actively use AI tools in your own workflow — not as a novelty, but as a genuine productivity multiplier. You stay current with the state of the art and know how to apply the latest research to real product problems. You communicate clearly and directly. You can explain technical decisions to non-technical stakeholders, flag blockers early, and collaborate effectively in a small, fast-moving team.Будет плюсом A Master's or Ph D in machine learning or a related area is a strong plus — but not a requirement if you can demonstrate equivalent depth through your work; A strong Git Hub and/or Hugging Face profile is a significant advantage; Experience with the Hugging Face ecosystem (Transformers, Datasets, Hub) is a strong plus; Experience across multiple model domains (vision, audio, NLP, multimodal); Familiarity with on-device or edge inference optimization (quantization, distillation, ONNX); Experience integrating ML models into mobile or production environments; Published research or open-source contributions in ML Условия Attractive compensation, above market averageHybrid work model based in BarcelonaHigh ownership from day one — you define the direction, not just execute on itWork directly with the founders and a senior, low-ego teamA real product with real users — your work will have immediate, measurable impact #J-18808-Ljbffr
