Senior Applied Scientist (Scheduling and Optimization)

TL;DR

Senior Applied Scientist (Scheduling and Optimization): Developing a constraint-solving engine for an AI-powered Scheduling Agent with an accent on CP-SAT and Python optimization. Focus on modeling complex real-world scheduling constraints and integrating the solver with GenAI agent workflows.

Location: Remote (Canada)

Company

hirify.global is an AI-powered maintenance and asset management platform serving over 13,000 customers worldwide.

What you will do

• Own and evolve the Python optimization service using CP-SAT to power the Scheduling Agent.
• Design sophisticated scheduling capabilities, including trade/crew constraints, downtime windows, and multi-site considerations.
• Build and maintain API routes to expose the solver to GenAI agent workflows via tool calling and structured I/O.
• Partner with PM and design to translate real-world scheduling problems into solver constraints.
• Iterate the solver based on feedback from human schedulers and pilot deployments.
• Ensure the performance, observability, and reliability of the optimization runtime.

Requirements

• 5+ years of professional software engineering experience in optimization, constraint programming, or operations research.
• Strong fluency with CP-SAT and at least one other optimization paradigm (e.g., MILP via Gurobi, CPLEX, or HiGHS).
• Solid Python service engineering skills, including APIs, async, testing, and profiling.
• Academic foundation in Operations Research, Industrial Engineering, Computer Science, or a related quantitative field.
• Proven track record of iterating optimization systems based on real-world user feedback.
• Must be based in Canada.

Nice to have

• Experience shipping optimization or scheduling products at scale in a reputable product company.
• Exposure to learning-augmented optimization using historical execution data.
• Domain experience in workforce management, field service, manufacturing, or logistics.
• Tech-lead experience or interest in growing into a leadership role.

Culture & Benefits

• Competitive salary and meaningful equity opportunities.
• Comprehensive healthcare, dental, and vision coverage.
• 401(k) / RRSP enrollment program.
• Flexible "take what you need" PTO policy.
• Meritocratic culture based on the values of being Smart Humble Optimists.
