Day-to-day:

• Works?on the mathematical optimization model at?the?heart of a task assignment model adhering to some complex work rules
• Formulate and maintain?the?MIP
• Translate?real business?rules into formulation with planners
• Drive the?model?through the FICO Xpress Java API,?generate/inspect .lp files and solver?logs.
• •Tune?the solver; mip-gap, mip-abs-gap, threads,?random?seed, determinism;?reason?about branch-and-bound performance?and runtime.
• Keep?the?model solver-agnostic behind?the LinearExpression / LinearConstraint / Sense /?Sign abstraction so?it stays?testable and portable.
• Validate & benchmark solutions
• Analyze data stored in Azure?ADLS?to?debug the?model?and find?issues;?mine input/output?datasets and?solver logs to surface?data-quality?and?infeasibility problems, derive insights, diagnose?root?causes,?and resolve modeling bugs (e.g., bad defaults,?constraint conflicts).
• Build and maintain?the Streamlit dashboard?(Python) that visualizes?optimizer solutions - code and ship changes?directly.
• Work fluently with AI coding agents?(Claude?/ Copilot /?similar) to prototype and change?models, scripts,?and the?dashboard fast without lowering the bar on?correctness or?code quality.
• ?Partner closely as a team?player with the Java?engineer to productionize
• Work with OR&AA team members and IT partners to gather requirements, ask questions, and influence our product and business unit teams to deliver high value/impact features to our products.

Job Description:

• Create detailed project specifications requirements and estimates
• Research and implement new AI technologies to enhance current processes security and performance
• Work closely with data scientists and product teams to build and deploy machine learning models focusing on the technical aspects of model deployment.
• Implement and optimize Python-based ML pipelines for data preprocessing model training and deployment.
• Monitor model performance and implement strategies for bias mitigation and explainability.
• Responsible for ensuring models are scalable and efficient in production environments.
• Write and maintain code for model training and deployment collaborating with software engineers to integrate models into applications. - Partner with a diverse team of experts leveraging cutting-edge technologies to build scalable and impactful AI solutions.
• Bachelor's degree in Computer Science Computer Engineering Data Science Information Systems CIS/MIS Engineering or related technical discipline or equivalent experience/training
• 7 to 9 years of full Software Development Life Cycle SDLC experience designing developing and implementing large-scale machine learning applications in hosted production environments
• 2 years of professional design and open-source experience

Nice To Have:

• Java21 / Spring Boot familiarity clean/hexagonal model design ports adapters TDD JUnit5 foroptimization models LP-file integration tests scheduling/assignment/routing problem experience heuristics/metaheuristics/CP as complements to MIP data analysis debugging mining datasets incl.
