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.\nOur goal is simple: to help households reduce both their carbon footprint and their energy costs.\nWith 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.\nAbout the role\nIn 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.\nWe’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.\nYou’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.\nIf you enjoy turning ML models into production systems that create measurable customer impact, we would like to hear from you.\nWhat you’ll be doing\nBuild and improve ML and optimization models that power customer-facing energy optimization features.\n\nWork on time-series forecasting, scheduling, and decision models for heat pumps, batteries, solar, tariffs, weather, and customer behaviour.\n\nProductionise and own models end-to-end, including deployment, monitoring, reliability, and iteration based on real-world outcomes.\n\nRun experiments on real customer systems, evaluate impact, and turn results into product decisions.\n\nContribute to initiatives from discovery to production impact, helping define success metrics and align with stakeholders.\n\nCommunicate clearly with technical and non-technical audiences, explaining trade-offs, uncertainty, model behaviour, and what is good enough to ship.\n\nWhat you’ll bring to the role\nExperience building ML, data, or optimization systems that are used in real-world products.\n\nGood programming skills in Python and software engineering fundamentals.\n\nExperience taking models beyond notebooks, including evaluation, testing, deployment, or monitoring.\n\nExperience with cloud platforms such as AWS, GCP, or Azure.\n\nComfort working with real-world data, including ambiguity, imperfect signals, and changing requirements.\n\nA pragmatic, product-oriented mindset: you care about measurable customer impact, not model complexity for its own sake.\n\nClear communication skills and the ability to collaborate well in cross-functional teams.\n\nBonus points if you have\nExperience with energy systems, electricity markets, demand response, or flexibility.\n\nExperience with constrained optimization, control systems, or physical systems modelling.\n\nWhat is in it for you?\nGain hands-on experience in a fast-growing scale-up, with a supportive and inclusive culture, and career advancement opportunities.\n\nCollaborate with diverse teams across international markets and launch products globally.\n\nDevelop and grow personally and professionally in an entrepreneurial-minded environment.\n\nThrive in a dynamic, solution-oriented culture, tackling challenges and driving meaningful solutions that make a positive impact on the world.\n\nInfluence the company's success, with a visible impact on product development and market growth.\n\nEnjoy 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.\n\nAt 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.","description_format":"text","description_chars":4759,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Manufacturing","HVAC & Refrigeration"],"lifecycle":[{"event":"open","at":"2026-09-28T20:36:20Z"}],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.388,"p_room":0.28,"age_days":82,"expected_fill_days":28,"reasons":["conf:8","win:tail","crowd:"],"computed_at":"2026-10-01T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/aira-machine-learning-engineer-energy-optimization","json_url":"https://alion.io/job/aira-machine-learning-engineer-energy-optimization.json","meta":{"generated_at":"2026-10-01T21:36:09Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":4239,"day_limit":5000,"remaining_today":761,"minute_limit":60,"resets_at":"2026-10-02T00:00:00Z"}}}
