As a Software Engineer at American Plastics (MO), your primary responsibility is to develop and maintain the digital infrastructure that supports our manufacturing lines. You will work closely with other engineering teams to automate reporting, streamline data collection, and improve the overall efficiency of our production processes.

Expect to spend your time writing code, performing system integrations, and troubleshooting issues that arise on the factory floor. You will act as a bridge between the digital and physical worlds, often collaborating with mechanical and process engineers to ensure that our software solutions are perfectly aligned with the hardware they monitor. This role is highly hands-on and requires a proactive mindset to identify opportunities for process improvement.

A strong candidate for this role will have a solid foundation in software development and a keen interest in applying those skills to manufacturing.

• Must-have skills – Proficiency in at least one major programming language, experience with database management, and a strong understanding of version control systems.
• Nice-to-have skills – Prior experience in a manufacturing or industrial environment, knowledge of IoT/sensor integration, and familiarity with data visualization tools.
• Experience level – We welcome candidates who are early in their careers and eager to learn, provided they demonstrate strong foundational knowledge and a drive for continuous improvement.

Q: How much preparation time is recommended? A: We recommend setting aside at least one to two weeks to review your technical fundamentals and research our company’s manufacturing focus. Consistent, focused practice is more effective than last-minute cramming.

Q: What differentiates a successful candidate? A: Successful candidates are those who can demonstrate both technical competence and a genuine interest in how their code impacts our production output. Showing that you understand the "why" behind your technical decisions is key.

Q: Is there a specific coding language required? A: While we use various tools, the ability to demonstrate strong computer science fundamentals is more important than mastery of a specific language. We prioritize candidates who can show they can adapt to our stack.

Q: What is the work environment like? A: Our environment is collaborative, fast-paced, and centered on continuous improvement. You will work in an office environment but will frequently interact with the production floor to understand the systems you are developing.

• Understand the Business: Take time to learn about the plastics manufacturing process. Understanding the constraints of the floor will make your software solutions much more relevant.
• Be Concise: When answering behavioral questions, use the STAR method (Situation, Task, Action, Result) to keep your responses structured and impactful.
• Ask Questions: We encourage you to ask about our development processes, team structure, and current challenges. It shows you are engaged and thinking critically about the role.
