Job Description

Opportunity

The Role
We’re looking for a Senior Data Scientist with strong skills in simulation modeling, mathematical optimization, and sensor data analysis. This is a hands-on, high-impact role where you will develop analytical solutions for real-world defense scenarios — from optimizing aircraft maintenance schedules to analyzing live sensor data from naval vessels.
You’ll be joining a cross-functional team that builds scalable, data-driven products supporting mission readiness and capability management. If you enjoy combining discrete-event simulation, CPLEX optimization, and sensor analytics to answer hard operational questions, this job will suit you well.

Your mission

Key Responsibilities:

Simulation Modeling
  • Design and develop discrete-event simulations using SimPy (or similar) to model logistics chains, maintenance workflows, and operational bottlenecks.
  • Build simulation components that reflect real-world systems, allowing for stress testing and what-if scenarios.
Optimization (CPLEX)
  • Build and solve optimization models using IBM CPLEX.
  • Translate complex operational needs — such as scheduling, resource allocation, or planning — into mathematical formulations.
  • If you’ve used Gurobi or other solvers before, that's fine — but you’ll need to work with CPLEX here.
Sensor Data Analytics
  • Analyze high-volume, high-frequency sensor data from military platforms (air, land, sea).
  • Extract signals, detect anomalies, and engineer features for predictive modeling.
  • Combine time-series analytics with simulation and optimization outputs to inform decision-making.
Engineering & Collaboration
  • Write clean, modular Python code with attention to performance and reproducibility.
  • Collaborate with data engineers, full-stack developers, and domain experts to productionize your models.
  • Share knowledge across teams and contribute to internal tooling and frameworks.

Your capabilities

What We’re Looking For/ Required Skills
  • 5+ years of experience in Data Science, Operations Research, or a similar role.
  • Strong coding skills in Python, including libraries like pandas, NumPy, matplotlib, scikit-learn.
  • Solid experience with SimPy or any other discrete-event simulation library or tool.
  • Practical experience formulating and solving optimization models with IBM CPLEX (knowledge of other solvers is welcome, but CPLEX is what we use).
  • Experience working with sensor or time-series data in an applied setting.
  • Strong problem-solving mindset — you enjoy turning ambiguous situations into concrete analytical approaches.
Bonus Experience
  • Background in logistics, maintenance planning, systems engineering, or defense operations.
  • Experience with containerized development (Docker) or distributed data tools (e.g., Apache Spark).
  • Exposure to digital twins, operational dashboards, or predictive maintenance applications.
  • Familiarity with working in secure or regulated environments (defense, aviation, etc.).

About us

In defence operations, timing and reliable information shape every decision. Many organizations still rely on fragmented systems, limiting visibility and slowing execution. ILIAS Solutions connects logistics, maintenance, and operations into one integrated platform. This creates a single source of truth and enables teams to act on real time data across strategic, operational, and tactical levels. Large volumes of operational data move continuously between systems. This data reflects maintenance cycles, logistics flows, and asset readiness. Accuracy and consistency directly impact operational outcomes.

Core Responsibilities

Develop analytical solutions for defense scenarios using discrete-event simulations and mathematical optimization to improve mission readiness. Analyze high-volume sensor data from military platforms to detect anomalies and inform operational decision-making.

Requirements

Requires 5+ years of experience in Data Science or Operations Research with strong proficiency in Python and IBM CPLEX. Must have practical experience in simulation modeling and working with sensor or time-series data.
