Australia's grid is the constraint. We are building past it.

Symphony develops, delivers and operates the high-voltage assets that connect renewable energy, storage and data centre projects to the grid.

Two of the largest investment waves of our generation are converging on the same physical interface. Decarbonisation puts power in. The AI build-out takes power out. Both depend on connection, and delivery capability is what decides which projects get built.

Behind us sits 11.7 GW of connections managed, 100+ high-voltage substations, 5,000 km of powerlines and 1,300+ specialists in-house nationally, backed by a $488 million Series A led by Blackstone.

The Role

Our business runs on software we build ourselves: a suite of internal applications covering project delivery, safety, asset management and commercial workflows. Our project teams, engineers, site crews and commercial staff use them every day to deliver real work.

You will be working genuinely full-stack across the whole suite. You will take ownership of an internal system, sit down with the department heads who depend on it, and design and build what they actually need. Decisions get made in the room, and there is nothing sitting between you and the outcome.

Because the software supports physical infrastructure, you will get out to site. Seeing a substation being built changes how you think about the tool the commissioning team uses to record it.

We also use AI heavily in our own development workflow. We would rather hire someone who has formed a considered view on how to do that well than someone who avoids it.

The Team

We are a small in-house engineering team inside a business of 1,300+ people, which shapes how we work. Everyone knows what everyone else is building. Requirements do not arrive as tickets from a product layer,



they come from a conversation with the person who has the problem. When something is hard, we work it out together rather than leaving whoever picked it up to sink.

Feedback runs in both directions, including on the decisions the team lead makes. Nobody here is precious about their own work.

The office is in the Melbourne CBD, close to Southern Cross and Flinders Street, with end-of-trip facilities if you ride in. Two of the better parts of the job are not on any benefits list: you will meet the people who use what you built, and you will occasionally spend a day on a site watching high-voltage infrastructure go up.

What You Will Do

- Own an internal system end to end, from requirements through to production

- Work directly with department heads to design software that fits how the business runs

- Support the people using what we build, and close the loop back into the roadmap

- Build the internal tooling that makes the development team faster

- Contribute to systems planning and architectural design across the suite

Our Stack

Go, TypeScript, PostgreSQL, MySQL, Docker and Git.

We care far more about the depth of your fundamentals than about matching this list exactly. If you have built real systems with comparable tools, you will be fine here.

What We Are Looking For

Required

- 3+ years building production software

- A up-to-date frontend framework: Angular, Vue, React or Svelte

- Relational databases such as MySQL or PostgreSQL

- REST API design

- Confident with Git





- Existing permanent working rights in Australia

Nice to Have

- Integration testing

- AI coding tools

- Linux and CI/CD

- Cloud infrastructure

How You Work with People

- Collaborative by default. You share context early, ask for a second opinion before you have burned three days, and you would rather solve it with someone than alone

- Clear communication with both engineers and people who have never opened a terminal, in writing and in the room

- You give and take code review well, and you separate the critique from the person

- Comfortable gathering requirements from people who are not sure what they want yet

- You follow through. If you own it, it gets to production and stays working

Beyond the Technical

- A good eye for UX and interface design

- Strong self-organisation

- Discretion with sensitive commercial and client information

What We Offer

- Hybrid working, with an accessible Melbourne CBD office

- 12% superannuation and salary sacrifice options

- Paid overtime with penalties, or bank the hours as time in lieu

- Minimal bureaucracy. A small team, short decision paths, real ownership

- Opportunities to get out to site and see the projects your software supports

- Training and development mapped to where you want your career to go, including conferences and certifications

- Your choice of development hardware and tooling

- A path into technical leadership as the platform team grows with the business

- Employee assistance program, and a business that takes safety and wellbeing seriously because of the work we do
