Senior Operations Research Scientist

Ciklum is looking for a Senior Operations Research Scientist to join our team full-time in Poland.

We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.

About the role:

As a Senior Operations Research Scientist, become a part of a cross-functional development team engineering experiences of tomorrow.

As a Senior Operations Research (OR) Scientist, you will be at the forefront of building the optimization engine that powers our global delivery network, specifically focusing on courier assignment. Your mission is to develop and deploy critical mathematical models and algorithms that match couriers to orders in the most efficient way possible, solving complex real-time logistics challenges. You will dive deep into large-scale geospatial and real-time data to unearth valuable insights and develop scalable, reliable models for optimization.

You will collaborate closely with Data Scientists and Developers to integrate these solutions into our live dispatch systems.

Responsibilities:

Technical & Analytical Excellence:

• Algorithm Development:
  Design and implement mathematical models and algorithms (e.g., heuristics, meta heuristics, exact approaches/MILP, decomposition techniques) to optimize courier assignment and system performance
• Production Integration:
  Deploy and integrate developed OR approaches into our technological infrastructure, effectively utilizing cloud systems, event stores, and other relevant tools to ensure reliability and scalability
• System Optimization:
  Design medium to large-scale systems with superior technical standards, identifying improvements through monitoring and experimentation to enhance assignment efficiency and reduce delivery friction
• Data Analysis:
  Dive deep into large-scale geospatial and real-time data to analyze complex sets and derive actionable recommendations for process optimization

Strategy, Communication & Mentorship

• Strategic Impact:
  Contribute to long‑term planning meetings and roadmap decisions, creating business cases for new initiatives and delivering on commitments made during planning
• Stakeholder Engagement:
  Translate complex technical findings and OR concepts (such as the trade‑offs between different optimization techniques) into understandable insights for non‑technical business leaders to support decision‑making
• Innovation:
  Proactively research and apply knowledge of existing and emerging OR techniques to improve business decisions, and contribute to decisions regarding the adoption of new technologies

Requirements:

• Education:
  
  A Bachelor’s or a Master’s degree in Operations Research, Mathematics,Computer Science, Statistics, or a related quantitative field. A PhD degree is a plus
• Experience:
  
  4 to 5 years of professional experience in Operations Research or a related field
• OR Expertise:
  Advanced knowledge of OR techniques, modeling languages (e.g.Google OR Tools) and solvers (e.g. Gurobi, Highs)
• Programming
  
  Skills:
  
  Experience with Java. Knowledge of Python is a plus. Experience with Github workflows, containerization and cloud environments (e.g. Google Cloud,AWS)
• Project Mastery: A holistic approach to projects, from problem identification and business case creation to managing the full model lifecycle and maintainingproduction systems
• Behavioral
  
  Competencies:
  
  Resilience in the face of challenges, a customer-focused mindset, and the ability to find simple, sustainable, and scalable solutions

What`s in it for you?

• Strong community:
  Work alongside top professionals in a friendly, open‑door environment
• Growth focus:
  Take on large‑scale projects with a global impact and expand your expertise
• Tailored learning:
  Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company‑paid certifications
• Endless opportunities:
  Explore diverse domains through internal mobility, finding the best fit to gain hands‑on experience with cutting‑edge technologies
• Flexibil…
