Senior Data Scientist (Linear Optimization)

We are a team of nerds dedicated to collect other nerds that happen to be the best in their respective fields in the broadly understood IT service and analytics. And with them we go out of our way to create IT and Analytical Hubs which bring together best experts from the IT world to help our partners to become real data driven entities.

Currently we are looking for a Senior Data Scientist as we are supporting our partner in developing Global Analytics unit which is a global, centralized team with the ambition to strengthen data-driven decision-making and the development of smart data products for day-to-day operations. The team is meant to be a nucleus radiating data-driven entrepreneurial culture by acting as incubator to realize ideas by simply doing it: creating smart data products in all areas of business, be it sales, marketing, purchasing, logistics or any other part of the company.

The team has a lot of freedom to shape this, especially in the use of tools and technology, but also by introducing new concepts, solutions and ways of working.

We are searching for a skilled Senior Data Scientist specialized in linear optimization to join existing team of top-class data science specialists responsible for the application of their expertise in machine learning, data mining and information retrieval to design, implement prototypes and build next-generation analytics engines and services.

As a Senior Data Scientist you will be responsible for developing, implementing and optimizing mathematical models to efficiently address business challenges, therefore you should possess strong mathematical and programming skills, along with practical experience applying linear optimization techniques.

If you want to:

• take part in the development and implementation of a complex system of smart data solutions
• have opportunity to work on bleeding-edge projects
• have a chance to see how your visions come true
• work with the world’s top IT professionals
• carry out projects which address real business challenges
• work in a global and diverse team with global reach

• working in modern office in the centre of Warsaw with good transport links or working remotely as much as you want
• a relaxed atmosphere at work where your passions and commitment are appreciated
• vast opportunities for self-development (e.g. online courses and library, experience exchange with colleagues around the world, partial grant of certification),

it’s certainly a good match!

If you join us, your responsibilities will include:

• understanding business problems and designing smart data products
• cooperating well with business to unpack ambiguous projects into clear requirements
• formulate business problems into mathematical optimization models
• creating linear and/or mixed-integer programming (MIP) models to address various business problems using Python and relevant libraries
• optimizing model performance and testing their effectiveness
• deploying solutions in collaboration with Data Engineers and MLOps team

We expect:

• strong background in linear algebra, calculus and mathematical optimization
• understanding of linear programming (LP) and mixed-integer programming (MIP) concepts and experience in applying these techniques
• university degree in Computer Science / Statistics / Mathematics / Artificial Intelligence / Physics or related technical discipline
• knowledge of machine learning, statistics, simulation or related fields
• fluency in applying Data Science methods (including ML) while solving business optimization problems
• at least 3 years of experience in similar role
• proficiency in Python programming (some experience with Pyomo would be a plus)
• familiarity with optimization libraries and frameworks such as PuLP, CVXpy or Gurobi
• experience with data manipulation tools and libraries, like pandas
• strong skills in translating real-world problems into mathematical models
• ability to formulate linear optimization problems and understand their constraints
• proficiency in optimization of algorithms and code for efficiency, especially when dealing with large-scale linear programming problems
• knowledge of parallel computing and distributed computing concepts
• strong software engineering skills (including unit testing, OOP)
• experience with versioning systems (e.g. Git)
• knowledge of basic DevOps tools and methods such as Docker, Kubernetes, CI/CD pipelines
• experience in deploying to production and ability to plan a product including broader technical landscape (ability to design and deliver product following modular approach)
• experience working in organizations with the agile culture
• team player
• ability to work autonomously to deliver complex projects
• fluent English as you will communicate in English almost all the time
• experience with Azure stack would be a plus
