Build the Next Generation of AI Products with TensorOps

TensorOps 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 Agents
  • Traditional Machine Learning: Time Series Forecasting, AdTech, Computer Vision, etc.
  • MLOps: Improving ML pipelines at scale

Core Stack:

As we work with many clients, our stack varies, but we often use:

  • Python APIs: FastAPI
  • Containerization: Docker, Kubernetes
  • Model Training & Serving: LightGBM, CatBoost, PyTorch, HuggingFace
  • Data Engineering: Pandas, Polars
  • LLM Frameworks: LangChain, LangGraph
  • Observability: MLFlow, Langfuse
  • Cloud Platforms: AWS, GCP
  • Search: Elasticsearch, OpenSearch, Solr

The Role

As 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 You

  • 3+ 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 impact
  • Mentorship from engineers who have shipped ML systems at scale
  • Competitive 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: €48,000-60,000
  • Travel expenses allowance
  • Urban Sports Club membership
  • Free Professional Certifications
