As a Software Engineer at Fulfil Solutions, your primary responsibility is to design, implement, and maintain the software that powers our automation platforms. You will work closely with the systems and mechatronics teams to define requirements for new features and ensure that your software integrates seamlessly with our electrical and mechanical hardware.

You will be involved in the full product lifecycle, from initial design and prototyping to validation and deployment at customer sites. A typical week may involve writing firmware or control logic, participating in design reviews for safety compliance, and troubleshooting issues during system bring-up. You are expected to be an active participant in our safety culture, ensuring that all software deployments adhere to rigorous industrial standards.

We are looking for individuals who are technically strong and comfortable operating in a fast-paced environment where software meets hardware.

• Must-have skills:
  • Strong software development fundamentals.
  • Experience in robotics, automation, or industrial control systems.
  • Ability to work with hardware-level communication protocols.
  • Excellent communication skills for cross-functional collaboration.
• Nice-to-have skills:
  • Experience with functional safety standards (ISO 13849, IEC 61508).
  • Prior experience in a startup or high-volume manufacturing environment.
  • Familiarity with Linux and Git version control.
  • Practical experience with industrial electrical systems or PLCs.

Q: How much should I prepare for the technical rounds? A: Focus on your past project experiences and your ability to explain your design decisions. Be ready to articulate how you handle technical trade-offs, especially those involving safety or hardware limitations.

Q: What is the company culture like? A: Fulfil Solutions is highly collaborative and multi-disciplinary. We value curiosity, a "can-do" attitude, and a commitment to safety. You will be expected to work across team boundaries and contribute to building a positive, efficient engineering culture.

Q: Is there much travel involved? A: Depending on the specific team and project, some roles may require travel for site deployments or commissioning. Refer to your specific job posting for details, but be prepared for a small percentage of time in the field.

Q: What differentiates successful candidates? A: Successful candidates often demonstrate a "hands-on" aptitude—they aren't afraid to get their hands dirty in the lab or troubleshoot a machine on the floor. They also show a clear understanding of the safety implications of their work.

• Emphasize Safety: Always tie your technical answers back to safety and reliability. This is a core value at Fulfil Solutions.
• Be Collaborative: Highlight your experience working with mechanical or electrical engineers. Our best work happens at these intersections.
• Show Your Work: When discussing past projects, be ready to explain the "why" behind your technical choices, not just the "what."
• Stay Curious: We are building technology that doesn't exist yet. Show that you are excited to learn and solve novel problems.

The Software Engineer role at Fulfil Solutions is a unique opportunity to shape the future of automation and sustainable food supply chains.
