Join AQUABATTERY today, a pioneering climatetech startup with a mission to commercialise a affordable, safe and sustainable long duration energy storage (LDES) based on saltwater. Our innovative flow battery technology offers an LDES solution without relying on critical or toxic raw materials.

With fresh funding secured and our first commercial product on the horizon, this is an exciting time to become part of our growing team and contribute to building a cleaner, more resilient energy future.

As an Software Development Intern, you will support the development of an internal lab inventory system to improve how we track and manage key components used in our R&D processes. Working with a modern Python-based stack, you will contribute to building a practical tool that helps the team operate more efficiently and make better use of resources. This is a hands-on role where you will work with real data, contribute to an existing codebase, and see the direct impact of your work.

The internship will have a duration of 4 months with the required availability of 3-4 days per week.

• Contribute to the development of an internal lab inventory system
• Work on a Python-based backend to track key lab components such as membranes, chemicals, and spacers
• Expand and maintain a PostgreSQL database to support inventory tracking
• Develop and improve features within the existing codebase
• Write tests to ensure reliability and maintainability of the system
• Collaborate with the team to understand requirements and translate them into technical solutions

We expect from you

• Currently enrolled as a student in Software Development, Computer Science, or a related field
