Senior Software Engineer (Tech Lead)

Job Title: Senior Software Engineer (Tech Lead)

Location: (including hybrid): Melbourne, Australia

Salary: $160,000 - $185,000 Superannuation

Kaluza reimagines energy to bring net-zero within everyone’s reach. The Kaluza Platform enables energy utilities to unlock the full value of a radically changing energy system and propel us to a future where renewable energy is sustainable, affordable and accessible for all. 

From automating and simplifying core operations including billing to create a lower-cost, higher-engagement experience, to optimising energy usage across smart devices in the home, we turn tough challenges into win-win-win outcomes for customers, suppliers and the energy system. 

We champion a flexible, hybrid work approach and we find that teams often benefit from coming together in the office at least 2-3 days a week to foster connection and accelerate progress. 

Outside of these collaborative opportunities, we aim to be as flexible as possible to balance work with life. As a company we come together annually for our conference and end of year celebrations! 

Our goal is to build a self-sufficient and empowered team here on the ground in Australia. We’re well on our way, but until we get there we still have some reliances on our UK team. Being comfortable working flexibly for a portion of your working week to cover time zones is required. 

What will I be doing?

You'll be joining the Kaluza Technology community. We’re a large team of both data-led and product focused Software and Production Engineers, pushing the boundaries of technology and working at an extraordinary scale. As a collective we strive for engineering greatness and by ensuring best practices across the board of the community.

You’ll be working with Kaluza’s energy optimisation and sales solutions, known as The Zoo. The Zoo is made up of SaaS technology platforms that aim to modernise the pricing and quoting process, and provide meaningful data visualisations for energy retailers globally.

About You 

We believe strongly in shared ownership of both responsibilities and successes across our team. As a Tech Lead, you’ll play a key role in shaping and delivering our work from the outset. You’ll be exposed to — and help lead on — many aspects of our diverse portfolio, contributing to everything from hands-on engineering to technical decision-making and mentoring.

Our teams build, test, deploy, and support a range of services that manage the customer lifecycle and metering data for the Kaluza platform, using a wide variety of technologies. While you don’t need to have prior experience with all of them, you’ll bring strong engineering fundamentals and a track record of quickly picking up new tools and practices. You’ll typically work with TypeScript and interact with technologies including GitHub Actions, Terraform, Kubernetes, Serverless, DynamoDB or Postgres, AWS, and DataDog.

We follow agile practices and use tools like Miro, Confluence and Jira to support collaborative working and delivery. You’ll help drive good practices, shape team ceremonies, and evolve how we work.

As a Tech Lead, you’ll be involved in the full development lifecycle: from contributing to technical discovery and architectural design, to rapid prototyping, backlog refinement, development, deployment, and operational monitoring. 

You’ll also play an important role in growing our team's capability — mentoring engineers, contributing to cross-team initiatives, and helping define the future direction of our platform.

Some of the challenges you'll help us tackle include:

• Designing abstractions that reduce complexity across multiple clients and markets
• Scaling systems to handle millions of data points efficiently and reliably
• Building extensible services that support configurability and future growth

Kaluza is in an exciting phase of international expansion, and we’re looking for experienced engineers who are excited to shape the next stage of our journey.

What will set you apart 

Ideally you’ll have/be

• Genuinely passionate about building products that make a meaningful difference — for millions of customers and the planet
• A strong collaborator who thrives in team environments and enjoys working closely with others to deliver impactful features
• Motivated by owning products end-to-end — from shaping the early technical direction through to iterating based on real-world feedback
• An advocate for test automation, continuous delivery, and modern agile practices — and keen to help others adopt them too
• Experienced in building scalable, resilient, and observable systems in production environments
• Curious and growth-oriented — always looking for opportunities to deepen your expertise or explore new areas
• An experienced hands-on engineer with solid proficiency in TypeScript, and deep experience with AWS services such as Lambda, S3, and DynamoDB 
• A contributor to a wide range of systems and technologies, bringing breadth as well as depth to your technical work
• Well-versed in modern engineering practices and principles of continuous delivery
• Experienced in building and optimising high-performance applications
• A natural mentor — someone who enjoys sharing knowledge, offering guidance in code reviews and pairing sessions, and helping others grow
