Mid-Level AI/ML Engineer

Build the Next Generation of AI Products with TensorOpsTensorOps is an applied-machine-learning studio that helps organisations across Europe and North America design, train, and deploy production-grade GenAI systems. Our team blends research depth with pragmatic engineering, and we’re looking for experienced engineers to help us build and scale our solutions.What We’re Working On:Generative AI applications: Chatbots and AgentsTraditional Machine Learning: Time Series Forecasting, AdTech, Computer Vision, etc.MLOps: Improving ML pipelines at scaleCore Stack:As we work with many clients, our stack varies, but we often use:Python APIs: FastAPIContainerization: Docker, KubernetesModel Training & Serving: LightGBM, CatBoost, PyTorch, HuggingFaceData Engineering: Pandas, PolarsLLM Frameworks: LangChain, LangGraphObservability: MLFlow, LangfuseCloud Platforms: AWS, GCPSearch: Elasticsearch, OpenSearch, SolrThe RoleAs a Mid-Level Machine Learning Engineer, you will be a key contributor to our project teams, taking ownership of core components and shipping robust AI/ML systems. This is a hands-on role from day one, working on real projects that make a tangible impact.You will:Design, build, and maintain production-grade ML systems, from data ingestion and processing to model deployment and monitoring.Develop and fine-tune generative AI models, including LLMs, for specialized tasks. You'll move beyond prototyping to build robust, scalable solutions.Architect and implement reliable data pipelines and low-latency inference services using our core stack (FastAPI, Docker, Kubeflow, AWS/GCP).Collaborate with senior engineers, researchers, and client stakeholders to translate business problems into technical solutions and deliver tangible value.Take ownership of key components of our ML platform, ensuring code quality, performance, and scalability.About You3+ years of professional experience in a software engineering or machine learning role.Strong proficiency in Python and its data science ecosystem (e.g., Pandas, NumPy, Scikit-learn).Hands-on experience building and shipping models using at least one major ML framework.Proven experience with the practical application of Large Language Models (LLMs). Familiarity with frameworks like LangChain/LangGraph and retrieval-augmented generation (RAG) is a significant plus.Solid understanding of software engineering best practices, including version control (Git), testing, CI/CD, and containerization (Docker).A BSc/MS in Computer Science, Software Engineering, or a related field, or equivalent practical experience.Why TensorOps?Fully remote (legal residence in Portugal required)Real-world projects, rapid feedback loops, and measurable impactMentorship from engineers who have shipped ML systems at scaleCompetitive compensation and growth opportunities - your growth will be based on ownership and performance rather than periodic reviews (which we still do)Compensation & Perks:Yearly salary: €48,000-60,000Travel expenses allowanceUrban Sports Club membershipFree Professional Certifications
