Job Description

Iterum is a seed-stage startup revolutionising appliance management for scaled residential properties. We're addressing a critical but overlooked challenge in property management: the inefficient handling of home appliances and consequential lack of actionable data. These things together lead to significant costs, wasted time, and increased carbon emissions. Our mission is to streamline appliance procurement and management, delivering substantial cost savings for property operators and investors, enhancing resident experiences, and reducing carbon footprints at scale. Our platform, Iterum IQ, is pioneering data accessibility and transparency in the industry, providing unparalleled control and optimisation throughout the appliance lifecycle.

This role offers the opportunity to guide architectural decisions, shape development best practices, and contribute to the culture of our growing development team.

If you have proven mid/senior-level full-stack engineering experience and the desire to build something from the ground up, we encourage you to apply!
