Machine Learning Engineer - Energy Optimization

Residential heating is one of Europe’s largest sources of CO₂ emissions, while energy prices remain unpredictable for many

households. At Aira, we’re on a mission to change that. Founded in 2022 and now employing more than 800 people, we develop and

install clean energy solutions—including heat pumps, solar panels, and battery systems—powered by intelligent technology that

helps homes operate more efficiently.

With headquarters in Stockholm, Sweden, a state-of-the-art manufacturing facility in Poland, and hubs across the UK, Germany, and

Italy, Aira is rapidly scaling to bring clean energy technology to 5 million homes by 2034.

About the role

In the Energy Optimization team, we build optimization and machine learning systems that help control when heat pumps run, when

batteries charge or discharge, and when it makes sense to export energy to the grid. We are also building new flexibility

capabilities by coordinating fleets of homes to support the grid when it matters most.

We’re looking for a Machine Learning Engineer to join this product team. You’ll work on models and systems that turn messy

real-world signals into reliable decisions for customers’ homes. This includes building and improving forecasting and optimization

models, productionising them, monitoring their performance, and iterating based on real-world outcomes.

You’ll work closely with Product, Engineering, Design, and other teams to ship customer-facing intelligence that is reliable,

understandable, and valuable. We value clear communication, thoughtful collaboration, curiosity, and a pragmatic approach to

problem-solving.

• Work on time-series forecasting, scheduling, and decision models for heat pumps, batteries, solar, tariffs, weather, and

customer behaviour.

• Productionise and own models end-to-end, including deployment, monitoring, reliability, and iteration based on real-world

outcomes.

• Communicate clearly with technical and non-technical audiences, explaining trade-offs, uncertainty, model behaviour, and what

is good enough to ship.

• Gain hands-on experience in a fast-growing scale-up, with a supportive and inclusive culture, and career advancement

opportunities.

• Thrive in a dynamic, solution-oriented culture, tackling challenges and driving meaningful solutions that make a positive

impact on the world.

• Enjoy our brand-new office at Norra Stationsgatan 93 in Stockholm. Conveniently located near public transport, with Sankt

Eriksplan and Odenplan stations just a few minutes walk away.

At Aira, we champion next-generation energy as well as diversity and inclusion. We firmly believe that a diverse workforce fosters

innovation and creativity, enhancing our ability to serve customers and communities effectively. We welcome individuals from all

backgrounds, cultures and perspectives to join our team. Our commitment is to uphold equality and inclusivity, fostering a

collaborative environment where everyone can thrive and contribute to a better future for our people and the planet.
