[Hiring] Optimization Engineer @ALICE Technologies

Role Description

As an Optimization Engineer, you will join the team that owns ALICE's scheduling engine—the algorithmic core that turns complex, resource-constrained construction projects into optimized schedules. You will design, implement, and productionize optimization models that solve large-scale combinatorial problems. This role is ideal for an engineer who loves hard mathematical challenges but possesses the discipline to turn research-grade ideas into fast, robust, production software.

Your Responsibilities

• Model & Design: Formulate and implement optimization models (MIP, CP, and custom heuristics) for resource-constrained scheduling problems.
• End-to-End Ownership: Take algorithms from mathematical formulation and prototyping through to benchmarking, tuning, and production delivery.
• Scale & Performance: Profile and improve the speed, scalability, and robustness of the scheduling engine on real-world customer projects.
• Cross-Functional Collaboration: Partner with product and software engineering teams to translate real-world construction workflows into precise technical requirements.
• Code Craftsmanship: Maintain high engineering standards through code reviews, rigorous testing, and continuous architectural improvement.

Qualifications

• Master’s or PhD in Operations Research, Computer Science, Applied Mathematics, or a related quantitative field.
• Strong proficiency formulating Mixed Integer Programming (MIP) and Constraint Programming (CP) models.
• Hands-on experience with solvers like Gurobi, CPLEX, OR-Tools, or Hexaly.
• Professional experience building and maintaining software used by real customers.
• Professional fluency in English.

Requirements

• Academic or industry experience specifically tackling intractable resource-constrained scheduling problems.
• Experience with JVM-based optimization libraries (e.g., OptaPlanner/Timefold, OR-Tools Java API).
• Experience building production services on the JVM (Spring Boot, Maven/Gradle, containerized deployments).
• Strong background in Agile methodologies and Test-Driven Development (TDD).
• Proficiency in modern Java.

Benefits

• High Impact: We are a lean, well-funded team where your work directly shapes the core product and company trajectory.
• Growth Opportunities: Rapid organizational growth means fast-tracked professional development and career progression.
• Category-Defining Product: Work on cutting-edge AI transforming one of the world's largest and most vital legacy industries.
• Total Rewards: Competitive salary, equity options for all employees, comprehensive health insurance, and a generous vacation policy.
• Location: Preferably Prague, Czech Republic, but remote is also possible.
