Senior Software/Data Engineer (AWS, Python)

About Us

Gridcog helps a broad variety of organisations assess potential investments in electrical energy systems, usually grid-connected.  We do this by allowing customers to build a model of their existing sites and energy assets, and run many alternative scenario simulations incorporating streams of time series data from live markets, forecasts, and real world meter data, leveraging a library of specifications of assets, pricing structures and financial schedules.  Our software is powerful, flexible and complex. 

Our very smart users aim to save time and money by not needing to build their own large Excel models and Python simulations. Our success lies in being extensively configurable.  We need people who are smart, curious, love to learn, and are driven; who relish the challenge to do hard things right.

Our software is used by customers around the world, with a current focus on Australia, the UK and Europe.   Customers include all participants in the energy system: suppliers, project developers, large energy users, and a growing ecosystem of technology providers and consultants.

We’re a small, talented and adaptable team.  Our people have a diversity of skills and backgrounds, and we strive to use and develop our different capabilities over a variety of projects.  We presently have around a dozen people in Engineering, around two dozen in the company – and we’re growing. We have clusters in London, Perth, and Melbourne, and few fully remote.  For this role, our preference is a candidate based in Melbourne or Perth, but open to exceptional candidates elsewhere.

Role Summary

We’re looking for a talented Senior Software & Data Engineer to join our data team.   Our platform is composed of a number of different subsystems built in Python and TypeScript, deployed to AWS, and accessed via GraphQL and a modern React app.  The focus of this role will be the components involved in data processing and visualization, but an ability to work across these different languages and technologies will be advantageous.

A key component of the Gridcog platform is ingestion and processing of a wide variety of data sources related to energy generation, usage and prices.  From energy regulators, energy suppliers, and customer assets such as solar and wind farms, and large scale batteries.  You will help evolve and maintain our Python codebases focused on data processing and presentation, to help customers design and deliver the most efficient and effective energy transition outcomes.
