Amber is an entirely new way of thinking about buying, banking and selling energy where home energy technology works to put money back in customers’ pockets and accelerate the renewable energy transition. We’re an Australian headquartered company, where we are both an energy technology company and a utility providing energy directly to households and small businesses. In Australia (the world leader on rooftop solar and a 2-way energy grid), we’ve proven that the cheapest, fastest and most rewarding way to reach 100% renewables is to automate the growing wave of home batteries, EVs, and other smart energy devices. Customers get direct access to the real-time electricity prices and the technology to shift energy usage to the times when cheaper renewables are available in the grid and export to the grid at times when the price they can be paid for it is highest. We are a clear market leader in energy automation in Australia, and are now partnering with utilities across Europe to bring our technology to European markets and consumers. We’re at a critical moment in taking the business to scale in Europe. You’ll be joining a rapidly growing regional team of 15, and be part of a global team of over 220, with expertise across energy, technology, marketing, and operations. We’re committed to building a diverse and inclusive workplace and a great culture of people who love coming to work to build a better world. We’re backed by leading VCs in Australia and Europe, as well as impact-focused investors and world-leading energy companies. At Amber, we believe that enabling a culture where everyone is set up to do the best work of their lives, and feels connected and supported, is one of the most important things we can do to ensure our long-term success. Want to help improve the environment by shifting the world’s energy usage towards renewables? We are currently hiring for a Full Stack Software Engineer. Amber provides a great opportunity to apply your skills as an Engineer to help enable the uptake of renewable energy. Our technology optimises thousands of batteries and other devices in the customers' homes, enabling them to time their usage to consume power at times of high renewable penetration (and cheap prices), and then export power back to the grid at critical times - letting them outbid energy generators and earn potentially >£50 in an afternoon. The Amber Electric product team develops and supports: • Home automation integrations (to batteries, hot water systems and pool pumps, with EVs coming soon) that control electricity usage in response to pricing and renewable availability, • Mobile & Web apps for customers to monitor and manage their energy usage, • A pricing and billing engine for real time energy pricing The tech stack is React Native mobile app, some React web frontends, and a Serverless Lambda backend on AWS. We’re using Typescript top to bottom, and Apollo GraphQL sits in the middle. We keep our data in DynamoDB, Postgres, and Snowflake, using one or the other as best suits a particular workload. You can learn more about our tech stack at _ While we’re looking for talented and driven individuals our desire is to build a champion team, not a team of champions.
