This role is posted on behalf of Super Tomato, a startup supported by SGInnovate.

Background

Super Tomato began as an automation company focused on helping B2B clients build custom automation machinery. Over the years, we expanded our capabilities by launching Monster Builder, a division dedicated to design and fabrication services. This allowed us to support a wider range of engineering needs across industries. Today, we have evolved into a product-driven organisation, developing our own in-house hardware brands—each with its own identity, technology stack, and market focus. Our goal is to scale these products internationally while maintaining the strong engineering foundations that have driven our success from the beginning.
