Systems Engineer

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

BackgroundSuper 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.

• 4. System Integration Oversight
• Understand how mechanical, electrical, PLC, and electronics components fit together.
• Plan and validate the system architecture of machines such as vending equipment or automation modules.
• Contribute to high-level design decisions and evaluate tradeoffs in architecture, components, and implementation.
• Troubleshoot integration issues at a supervisory level and coordinate solutions among technicians or vendors.
• 5. Supplier, Vendor & Freelancer Coordination
• Communicate technical requirements clearly to machine shops, electrical suppliers, technical freelancers, etc.
• Review quotations, drawings, and samples for technical accuracy.
• Track deliverables, ensure specs are met, and resolve technical discrepancies.
• Support technical purchasing decisions.
• 6. Project Management
• Coordinate multiple technical stakeholders and keep timelines on track.
• Plan integration milestones and ensure all parts of the system meet project goals.
• Maintain clear project documentation and version control.
• 7. Sourcing
• Source for new components, technologies, sensors, and integration methods.
• Evaluate feasibility and propose solutions that fit the system architecture.
• Support continuous improvement of machine reliability and performance.
