Technical Troubleshooting

This area is the cornerstone of the Software Engineer role. We evaluate your ability to identify the root cause of issues, whether they stem from software bugs or hardware misalignments. Strong performance involves demonstrating a systematic approach to diagnostics.

• System Diagnostics – Understanding how to isolate software errors from hardware faults.
• Documentation Standards – Maintaining clear, accessible logs for future maintenance.
• Tool Proficiency – Experience with the specific software suites used in our facilities.

As a Software Engineer at A&J Australia, your primary responsibility is to ensure the seamless operation of our engineering systems. You will spend your day-to-day analyzing technical requirements, writing and refining code for automated systems, and collaborating with the mechanical team to troubleshoot equipment.

You will often act as the link between the design team and the shop floor. This involves:

• Developing and testing software solutions that control mechanical processes.
• Performing regular system audits to ensure performance metrics are being met.
• Collaborating with cross-functional teams to implement process improvements.
• Providing technical support to ensure that all machinery is operating at peak efficiency.

We are looking for candidates who possess a solid technical foundation and a proactive approach to engineering challenges. While experience levels can vary, the following qualifications are essential for success in this position.

• Must-have skills: Proficient in relevant programming languages, strong diagnostic skills, and prior experience in an industrial or mechanical engineering environment.
• Nice-to-have skills: Familiarity with PLC programming, experience in high-volume manufacturing environments, and relevant certifications in software or systems engineering.
• Experience: A track record of delivering technical projects on time and a demonstrated ability to work in a team-oriented setting.

Q: How long does the hiring process typically take? A: We aim for a streamlined process, usually spanning a few weeks from the initial screen to a final decision, depending on team availability.

Q: What is the most important trait you look for? A: We prioritize a combination of technical curiosity and a "safety-first" mindset. We want engineers who are not only skilled but who also care deeply about the reliability and safety of the systems they manage.

Q: Is there a specific focus on remote work? A: This role is site-based, as it requires direct interaction with the mechanical systems and collaboration with the on-site production teams in locations like Laverton North or Wetherill Park.

• Prepare for "What-If" scenarios: Because this role is highly practical, expect interviewers to present you with a hypothetical system failure and ask how you would troubleshoot it step-by-step.
• Showcase your documentation: Bring examples or talk about how you keep your work organized; clear documentation is highly valued here.
• Align with our scale: Emphasize your ability to work on systems that are mission-critical to our operations.
• Be clear and concise: At A&J Australia, we appreciate direct communication. When answering questions, state your conclusion first, then provide the supporting details.
