Job Title: OR ScientistVendor Pay Rate: $80- 95OnsiteJob Description: 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.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 the?model?and with planners/SMEs to capture and?verify rules; document?assumptions?and?limitations.Top 3 Mandatory Skills and Experience (EX: education, software skills, licenses or certifications, etc.): 1. Mixed-Integer Programming (MIP)?modeling; formulating?real-world business?rules as?decision variables, linear?constraints, and?objectives; LP/IP theory; branch-and-bound intuition. 2. Commercial solver?experience; FICO Xpress (strongly?preferred) or Gurobi/CPLEX/OR-Tools/Hexaly, including solver?tuning (gaps, threads, seeds, determinism) and?reading solver logs?/.lp files. 3. Programming to implement model & visualize?model solutions; Java (the?model?lives in?Java behind a solver?abstraction); Python (incl. Streamlit for the?dashboard); able?to code and ship changes in both programming languages.Also required: comfortable?using AI coding agents?(Claude?/?Copilot) for fast?changes; high coding?standards; a collaborative team?player (open to?ideas/feedback, no solo work);?a fast?learner. (Education:?MS/PhD in OR /?IE /?Applied Math /?CS-optimization?or equivalent.)Nice to Have Skills and Experience (preferred but not required): Java?21 / Spring?Boot familiarity; clean/hexagonal model design (ports & adapters); TDD (JUnit?5) for?optimization?models?(LP-file integration tests); scheduling/assignment/routing problem experience; heuristics/metaheuristics/CP as complements to?MIP; data?analysis & debugging;?mining datasets (incl. Azure?ADLS) and?solver logs to find?issues and derive insights;?data wrangling (CSV/Excel/SQL); Git/GitHub, MongoDB Compass, Maven,?Docker; aviation / MRO domain. Describe a great candidate that you are looking for and what skills and experience they will have: A hands-on?optimization scientist who?has shipped MIP models into?production,?not just notebooks.?They can sit?with a?maintenance?planner, extract fuzzy operational?rules, and?turn?them into correct, well-scoped linear?constraints then make?the model solve?fast enough to be useful?(gap/seed/thread tuning, reformulation,?branch-and-bound?reasoning). They write maintainable,?tested code behind a?solver-agnostic abstraction, validate feasibility?rigorously,?and?communicate?trade-offs (objective?design,?soft vs hard constraints, default-value handling)?to both engineers?and business?stakeholders.?Genuine FICO Xpress (or Gurobi/CPLEX) depth?is the?rare, critical differentiator.?They hold high standards for?their code, are a collaborative team?player (open to?ideas?and feedback, no solo work), use AI coding agents?(Claude?/?Copilot) to iterate quickly, comfortably?build/change?a Streamlit dashboard, and?are a fast?learner. Perform analysis and derive insights from data.What is the team environment and structure like?: Part of?the OR & Advanced Analytics (OR&AA)?- TechOps/Mechanics squad.?A cross-functional team of OR?scientists,?software engineers,?and TechOps planning?SMEs, working agile with strong?engineering hygiene (PR review,?Sonar/JaCoCo/PIT, TechDocs) governed by the AA AI?Constitution (Spec-Driven?+?Test-Driven?Development).?High collaboration with Maintenance?operations stakeholders.How will the resource(s) fit into your team?: They define?the variables,?constraints, and objective?behind the abstraction layer and?own solution quality?and?solver?performance, while the Java?engineer owns the surrounding?service, data integrations,?and deployment.?Together?they form?the?core "Java/Spring engineering?+ MIP?optimization" pairing?that?makes?this?a specialized?OR?product?team rather?than a standard microservice?squad. They also interface directly with Maintenance?Planners to?validate?that optimizer?output beats?the?manual baseline
