Most Python software runs in the cloud and moves data around.
This role is different. Your code runs inside someone’s home, talks to their solar and battery inverter and EV charger in real time, and decides when to buy and sell electricity on the National Electricity Market. Every line you write has a direct physical consequence.
Reposit Power deploys a proprietary Linux controller to thousands of Australian homes. It’s the distributed brain of a virtual power plant — coordinating solar panels, batteries, EV chargers and smart appliances to trade energy on behalf of customers. We’re now doing early work on vehicle-to-grid (V2G) technology — using parked electric vehicles as grid‑scale batteries that can buy and sell electricity while sitting in the driveway. We’re a small, experienced team looking for engineers who want deep technical ownership and are excited to learn the hardware and electricity systems side of the problem.
WHAT YOU’LL WORK ON
Python-based electricity trading software running on ARM Debian Linux in the field
Real-time control logic that drives solar inverters, battery systems, EV chargers, hot water and AC units via Modbus — we’ll teach you the protocol
Early-stage vehicle-to-grid (V2G) development — bidirectional charging that turns parked EVs into dispatchable grid assets
System-level Linux work: networking (IPv4/IPv6), state management with Salt, connection management via connman
Hardware communication via UARTs, I2C and similar interfaces — closer to the metal than most Python roles
Software that has to work reliably in the field, unsupervised, at scale
WHAT WE’RE LOOKING FOR
Strong Python and Linux — the hardware and energy knowledge we can teach
Solid Python engineering: you care about correctness, performance and maintainability
Comfortable on Linux at the system level — processes, networking, services, filesystems
Experience with deployed software that runs without supervision in production environments
Curiosity about how things work at the hardware level — you don’t need embedded experience, but you shouldn’t be put off by it
Any exposure to IoT, industrial systems, home automation or energy is a genuine bonus
WHAT WE OFFER
High ownership on a small team — your engineering decisions shape the product
The chance to build genuine expertise in electricity systems, grid markets and energy hardware — skills that are becoming increasingly valuable
Technically unusual problems that don’t come up in typical backend or DevOps roles
Canberra base with genuine hybrid flexibility
Competitive salary commensurate with experience
