About the Role

We are looking for a Staff Engineer with deep expertise in simulation, optimization, and AI-driven forecasting to lead the development of advanced simulation frameworks and products for Home Energy Management Systems (HEMS). This role is central to our mission of enabling intelligent, cost-effective, and sustainable energy use in residential homes.

You will design and implement scalable simulation models that integrate photovoltaics (PV), battery storage, HVAC, heat pumps, EVSE, and other residential energy assets, and couple them with optimization solvers and machine learning-based forecasting algorithms to optimize energy bills of a homeowner. Your work will directly support product innovation, cost-benefit analysis, and strategic decision-making.

Key Responsibilities:

      Architect and implement simulation frameworks that can scale to millions of homes through modelling:

• PV systems, battery storage, HVAC, heat pumps, water heaters, EVSE, and grid interactions.

      Ensure scalability, modularity, and maintainability of simulation tools and its data pipeline.

      Conduct what-if analyses to evaluate the impact of different configurations (e.g., adding a second battery or changing tariff structures) on home-owner bill.

      Collaborate with product managers, data scientists, and software engineers to translate simulation insights into product features.

      Contribute to technical strategy, mentor junior engineers, and lead cross-functional initiatives.

      Documentation and recording of results

Key Qualifications:

      Bachelor’s or master’s degree in Electrical Engineering, Mechanical Engineering, Energy Systems, Computer Science, or a related field.

      7+ years of experience in energy systems modeling, simulation, or optimization.

      Strong experience with:

• Modeling of residential energy devices (PV, battery, HVAC, EVSE, etc.)
• Hands on experience of modelling simulation tools for home energy management
• Formulating and solving Mixed Integer Linear Programming (MILP) problems.

• Proficiency in Python and relevant libraries (e.g., Pyomo, Pandas, NumPy, Scikit-learn).
• Experience with simulation tools such as Energy Plus or any other open-source tools
• Proven ability to design and deliver scalable, production-grade software.
