At Norrin, you can grow in the direction that matters to you and build solutions that make a real difference.

Norrin has strong roots in Finland, but we are operating internationally across the Nordics, the United States and APAC.

We’re looking for a Data Scientist to join our Applied AI team. In this role you’ll get to design and implement solutions that apply mathematical optimization methods and modern technologies. You’ll be solving complex challenges such as logistics and production optimization and bringing solutions into production together with our team. In addition to optimization, you’ll have the opportunity to work on a variety of AI projects, from time series analysis and computer vision to LLMs/GenAI and agentic systems, shaped by your interests and our clients’ needs.

Responsibilities

• Design and implement solutions using mathematical optimization methods (linear, nonlinear, dynamic, stochastic, etc.)
• Conduct traditional ML modelling, MLOps and data analysis
• Program in Python and work with modern libraries and tools
• Collaborate closely with colleagues and clients while taking ownership of project outcomes

Why Norrin?

People‑first culture: A workplace where you can be yourself. Our culture is built on openness, equality, and mutual respect.

Flexible working model: Our hybrid model offers the best of both worlds, flexibility in everyday work and in‑person collaboration when it helps move things forward.

Well‑being benefits: Comprehensive well‑being benefits, including extensive occupational healthcare and dental care, insurance coverage, regular massages, and culture and sports benefits.

Fair compensation: Total compensation includes a base salary and a bonus tied to targets and results. You’ll also have the opportunity to participate in an employee fund.

Grow with us: You’ll have the opportunity to develop your skills and grow in a direction that matters to you. We offer a wide range of training and certification opportunities, as well as guild communities where knowledge is shared and built together.

What we value

• 3+ years of relevant experience in data science, applied mathematics, operations research, or a related field
• Hands‑on experience in designing and implementing solutions using mathematical optimization methods (linear, nonlinear, dynamic, stochastic, etc.)
• Strong programming skills in Python and solid understanding of linear algebra and statistical analysis
• Ability to translate complex real‑world problems into clear mathematical formulations and implement them in practice
• Ability to read, research and thoroughly understand academic papers and apply algorithms from them in our client solutions
• Good knowledge of version control (e.g. Git) and modern development practices
• Strong problem‑solving skills with a structured and systematic approach, combined with excellent teamwork and collaboration
• Ability to take ownership, deliver results and communicate effectively in English (both written and spoken)
• Advanced degree (Master’s or PhD) in operations research, applied mathematics, computer science, industrial engineering, or related disciplines

What’s a plus

• Familiarity with optimization frameworks
• Broader experience in machine learning / AI, such as time series analysis, computer vision, LLMs/GenAI, reinforcement learning or agentic systems
• Experience with PyTorch, deep learning or neural networks
• Understanding of data platforms and architectures (e.g. Databricks, Microsoft Fabric)
• Experience with MLOps and modern deployment practices (e.g. Docker, IaC)
• Consulting or client‑facing experience, and ability to guide teams as a technical lead
• Previous work in industrial sectors (e.g. heavy machinery, power generation, manufacturing), or in e‑commerce & b2c services
• Finnish skills are a strong advantage
