Junior Optimization Engineer – Revenue Distribution Focus

About Capalo AI At Capalo AI, we are accelerating the green energy transition by maximizing the value of large-scale energy storage systems through artificial intelligence and optimization. Our platform, Capalo Zeus VPP™, operates battery energy storage systems as a virtual power plant, helping asset owners generate higher revenues while supporting a more resilient and sustainable energy grid. The role As a Junior Optimization Engineer within our Revenue Distribution team, you’ll design and implement the mathematical framework that determines how aggregated market revenues are allocated back to individual battery assets in our fleet. This is an entry-level position, well suited to recent graduates and students in the final stages of their degree. This is a quantitative systems problem. When hundreds of batteries are optimized as one portfolio, their individual contributions are not directly observable. Yet revenues must be allocated in a way that is: Economically fair Mathematically defensible Robust to edge cases Transparent to asset owners Production-grade Your job is to formalize that logic and ship it. Key Responsibilities Design allocation methodologies Develop revenue-sharing mechanisms for heterogeneous battery portfolios Account for asset constraints, degradation, market rules, and temporal coupling Formalize contribution logic under portfolio-level optimization Build production-grade optimization logic Implement high-performance Python modules Handle large-scale time-series market data Write testable, well-documented, reviewable code Ensure numerical correctness and edge-case robustness Validate and stress-test Simulate volatile price environments Evaluate fairness metrics and sensitivity Adapt models as market rules evolve Integrate with core systems Deliver API-ready outputs used by Finance and customer-facing products Maintain documentation to ensure auditability and transparency What we're looking for Must-haves A completed or soon-to-be-completed degree in applied mathematics, physics, optimization, operations research, quantitative economics, or a similar quantitative field A strong academic track record Solid Python skills (NumPy, pandas) and familiarity with good software practices such as testing and version control, e.g. through coursework, projects or internships; exposure to SciPy, CVXPy or similar tools is a plus Ability to break down open-ended quantitative problems in a structured way, and eagerness to learn quickly Clear communication skills in English - able to explain mathematical reasoning to non-specialists Nice-to-haves Exposure to electricity markets or battery energy storage systems (BESS), e.g. through studies, a thesis or projects Coursework or projects involving revenue or cost allocation in multi-asset environments Studies in mechanism design or cooperative game theory Why this role is different You’re building core logic, not peripheral features. The allocation engine directly determines how real money is distributed. It’s close to real markets. The technology runs against live electricity markets and has real-world impact. The problem deepens over time. As we scale across markets and asset classes, allocation complexity increases.
