At OptiGrid, we’re building the tech to significantly improve the economics of grid-connected batteries and accelerate the clean energy transition. Through years of research and development, we’ve built a proprietary market forecasting and battery optimisation platform that substantially outperforms the status quo in the National Electricity Market (NEM).
Backed by prominent deep-tech and clean-tech investors, our team combining software engineering with deep NEM, forecasting, and energy market expertise is growing - and we’re looking for a (Mid-Level to Senior) Software Engineer to help us scale the platform.
This is an incredible opportunity to become an early and foundational team member at a climate-tech company that is at a growth inflection point, addressing a critical problem in one of the most important and fastest-growing markets.
What you’ll do
Collaborate closely with software engineers, data scientists, and energy market experts to deliver new product features and improvements.
Productionise forecasting and optimisation models in Python, ensuring they are robust, scalable, and production-ready.
Develop and maintain the data pipelines powering our forecasting, optimisation, and bidding workflows.
Set standards and establish best practices for our production codebase on AWS infrastructure using modern DevOps practices.
What you’ll bring
5+ years of Python experience, including strong fluency with Python’s numerical ecosystem (e.g. Pandas, Polars, NumPy).
3+ years of working in technical teams, building data pipelines, delivering productionised code, and building or maintaining live applications.
Experience with AWS microservices, containerisation (Docker), CI/CD automation (e.g. GitHub Actions), and Python-based API development (e.g. FastAPI).
Knowledge of infrastructure-as-code tools (e.g. Terraform).
A collaborative, curious mindset and a willingness to work across disciplines.
Experience working with power systems, energy markets, or NEM/AEMO data.
Exposure to mathematical optimisation libraries.
Experience building ML pipelines or working with time series data.
What you’ll love about working at OptiGrid
Competitive salary and generous Employee Share Options Plan.
Flexible work hours with hybrid or remote work arrangements.
Fast-paced, mission-driven environment where your code has direct real-world impact.
Work alongside a curious, ambitious, and tight-knit team solving hard problems together.
