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, enhancing resident experiences, and reducing carbon footprints at scale. Our core product, Iterum IQ, is pioneering data accessibility and transparency in the industry, providing unparalleled optimisation throughout the appliance lifecycle.

We've proven initial product-market fit, and are entering an exciting period of growth. We're seeking a talented and ambitious Mid-Level Full Stack Developer to join us as Senior Software Engineer, with potential to move quickly into a Head of Technology role, pending performance. The ideal candidate will be hungry to be a part of building something from the ground up, shape team culture, and prove themselves as a leader. Working closely with our Head of Product and supported by our Fractional CTO, you'll be instrumental in developing our product as we scale, with a focus on building and shipping AI/ML-driven features.

If you have proven mid/senior-level full-stack engineering experience, show leadership potential, and are eager to get your hands dirty at an early-stage company, we encourage you to apply!
