What you will be doing

We've built our internal data and R&D platform, and now we want to do far more with it — integrating AI and modern data science to turn the battery data we collect every day into faster insight and better products.
That's where you come in. We're looking for a versatile software engineer who's happy ranging across the stack — building data pipelines and APIs, automating workflows, working with databases and cloud infrastructure, and applying AI to extract more value from our data. You'll join our Platform & AI team and play a central role in a platform that underpins all of our R&D, product development, and service delivery.
You'll have genuine ownership here and you'll help shape how our data platform grows and how it connects to the rest of Breathe's systems.

Your day to day

  • Design and develop data pipelines that continuously collect and process time-series and metadata from battery test hardware, securely transferring and storing it in a central database

  • Build solutions that give our battery, solutions, and modelling teams easy access to data for analysis and customer projects

  • Automate data analysis, applying AI to increase the insight we generate

  • Design solutions that detect data errors early — whether human or system — so issues get flagged and resolved quickly

  • Help own the development of our database solution, keeping it reliable, maintainable, secure, and robust

  • Take projects from planning through implementation, testing, and verification across the software stack

  • Write high-quality, testable code, including unit and integration tests

  • Help plan how we scale the data platform and integrate it with other Breathe systems

  • Collaborate across teams to define requirements, solve problems, and establish best practices

Your background

  • Strong software engineering fundamentals and a generalist mindset — comfortable working across pipelines, APIs, databases, and infrastructure

  • Solid experience with Python, and with API frameworks such as FastAPI, Flask, or Django

• Experience using and architecting databases (e.g. PostgreSQL, MySQL)

• Experience with DevOps / platform engineering and CI/CD (e.g. GitLab CI)

• Experience with cloud and on-prem infrastructure (networking and resources in Azure, on-prem networking)

• Experience building data analysis pipelines handling time-series and metadata

• Familiarity with Databricks or other modern data platforms

• A proactive approach to identifying and solving technical and process challenges

• Ability to work cross-functionally in a Kind and Conscientious manner

• Adaptability in an innovative and rapidly scaling environment

We want to add the best talent to our incredible team, and we want to find you tomorrow. We will do our best to process your application as quickly as possible and come back to you within 2 weeks as we appreciate communication is key. But we aren’t perfect so do reach out to us for an update.

At Breathe, we believe that having diverse perspectives within our team is an essential part of innovating quickly, thinking from first principles, and expanding our expertise. Ultimately, enabling us to deliver better products to our customers.

We aim to attract, nurture, and retain diverse individuals. Because that’s how we do our best work. And because that’s the kind of world we want to live in. 

We welcome and encourage applications from all qualified candidates and are happy to provide the accommodations you need within our recruitment process to enable you to demonstrate your skills. Just let us know what you need.

So, what are you waiting for? Come join us!
