Software Engineer, Flex

Gridsight is a rapidly growing Grid/CleanTech startup on a mission to accelerate global electrification and decarbonisation. We are building a vertical SaaS platform for electricity utilities, enabling them to modernise grid operations and unlock transformational flexibility capabilities such as dynamic operating envelopes and flexible interconnections. Having recently raised our Series A funding from Airtree Ventures, Energy Transition Ventures and Area VC, we are poised for rapid growth and are seeking talented individuals to join us on our mission.

Flex is Gridsight's DER orchestration product: dynamic operating envelopes, emergency backstop, flexible exports, and battery orchestration. It's how utilities actively manage millions of solar systems, batteries, and EVs in near-real time, and it sits on top of the power flow and optimisation engine and services built by our grid modelling team.

We're standing up a dedicated Flex product team to turn that engine into a product utilities can run themselves. We're looking for a software engineer to cover the full stack: backend services, working with the data models that feed them, and the web-facing product surface where utilities see and operate their flexible resources.

On any given week you might be building a backend service, shaping a data model, or shipping UI. You won't be deep in the power flow maths, but you'll be the engineer who makes its outputs usable, observable, and operable in production.

What You'll Do

• Build and ship product features across the Flex stack: backend services, data models, and web UI
• Own features end-to-end, from understanding the problem through to shipping and iterating in production
• Build the product surface that lets utilities and internal teams self-serve: configuration, operational visibility, and reporting
• Work with the data models and services that feed Flex products
• Build the operational tooling and monitoring that keeps Flex deployments healthy across a growing customer base
• Collaborate with the grid modelling team to integrate power flow and optimisation outputs into product workflows
• Leverage AI-assisted development tooling to accelerate delivery and raise the bar on what a small team can ship
• Contribute to engineering culture: code quality, testing, observability, and knowledge sharing

What You'll Bring

• 3-6+ years of software engineering experience with a track record of shipping and running production systems
• Strong in at least one of backend, data, or frontend, and comfortable working across all three
• Experience shipping user-facing product features in production
• Strong engineering fundamentals: clean architecture, testing practices, code review, CI/CD - in service of shipping things that matter
• Fluency in the use of AI-assisted development tools - you're already using agentic coding tools, LLM-assisted workflows, or similar to accelerate your work
• Strong ownership and a bias to action - you take things from idea to working software without waiting to be told

What Would Set You Apart

• Experience in energy, utilities, or infrastructure technology
• Experience turning models, optimisation, or analytics outputs into production product features
• Frontend development experience with modern frameworks (React or similar)
• Data engineering fundamentals: pipelines, orchestration, warehouse internals
• Experience building LLM-integrated product features in production

What We Offer

• Competitive salary. We hold high expectations, but pay accordingly.
• Meaningful ESOP so you share in the growth of Gridsight.
• $2,500 WFH allowance, $2,500 health and wellness allowance, bi-annual in person working weeks, and lunch is on us when you're in office.
• Work how you like. Fully remote, hybrid or in office with a fresh, new head office in Sydney and satellite spaces in Melbourne, Brisbane and Hobart.
