AI Engineer - Decision & Optimization Systems

About the Role

We’re looking for an AI Engineer - Decision & Optimization Systems to own the feasibility, authority, and constraint layers that sit between AI reasoning and real-world execution.

In this role, you will build the systems that decide what plans are allowed to exist before any optimizer, agent, or human can act on them. Your work ensures that AI-generated logistics plans respect command hierarchy, policy, safety, and operational reality-so when we execute, we execute correctly.

You'll partner closely with routing, packing, optimization, and AI-agent teams to turn intent, authority, and uncertainty into decision systems that are auditable, enforceable, and explainable.

What You’ll Do

Build & Own Feasibility and Authority Models

• Design and implement models that encode command hierarchy, authority limits, and policy rules into formal feasibility checks.
• Convert outputs from AI agents (LLMs, planners, probabilistic models) into deterministic, enforceable constraints before execution.
• Ensure authority and policy interpretations are traceable, inspectable, and safe.

Constraint & Feasibility Frameworks

• Build and maintain a centralized constraint framework used across plaaning and optimization systems.
• Encode:
• Authority rules
• Timing Windows
• Compatibility constraints
• Asset availability and readiness
• Surface clear diagnostics for infeasible plans and constraint violations so both humans and machines can understand what failed and why.

Data Ownership & Validation

• Own the data inputs needed for feasibility and constraint enforcement.
• Define and enforce data contracts, normalization, and validation pipelines.
• Build robustness against incomplete, delayed, or noisy operational data.

Production Integration

• Integrate feasibility checks into real-time and batch planning pipelines.
• Partner with optimization and execution teams to gate every action on valid, policy-compliant inputs.
• Validate system behavior through scenario testing, simulations, and operational feedback from real users.

What We’re Looking for

Strong Engineering & Modeling Skills

• Proficiency in at least one of: Python, Java, Go, or C++
• Experience building constraint-based or rule-based systems in production.
• Experience integrating AI or agent-based reasoning into downstream decision or execution pipelines.

Optimization & Decision Science Background

• Degree or equivalent experience in Operations Research, Applied Math, Industrial Engineering, Computer Science, or related field.
• Strong understanding of: Linear programming, Mixed-integer programming, Constraint satisfaction systems.
• Experience using tools such as Gurobi, CPLEX, OR-Tools, Pyomo, AMPL, or equivalent.

Systems Thinking

• Ability to reason about feasibility vs optimality tradeoffs.
• Comfort integrating probabilistic or AI-derived outputs into deterministic systems.
• Strong instincts for debugging, failure analysis, and explainability in high-stakes environments.

Bonus Points

• Experience with logistics, supply chain, or routing systems.
• Experience working alongside optimization or planning teams.
• Exposure to defense, government, or mission-critical operations.
• Prior work integrating AI agents into decision or execution pipelines.

Mission and Identity

We are building the system that enables faster, smarter logistics decisions in contested environments, and we're doing it with a team of seasoned entrepreneurs, operators, and technologists who have built and scaled solutions in this space before. We hold ourselves to an extremely high standard. We value clear thinking, direct communication, and the kind of ownership that doesn't stop until something actually works.

• Our mission is to create decision advantage when the stakes are the highest.
• If we succeed, the system doesn't just run; it gets smarter.
• We're not building AI for its own sake.
• We're building it because faster, smarter decisions in the most demanding environments on earth can't wait.
• If you want to work somewhere the stakes are real and the mission is urgent - you'll fit in here.

Compensation
