The interview process for this role is designed to rigorously assess both your technical systems knowledge and your readiness for an on-site manufacturing environment. You will typically begin with a comprehensive recruiter screen that focuses on your background in capital projects and your willingness to work hands-on at the Richmond plant. This is followed by a technical deep-dive with engineering leadership, where you will discuss process modeling, automation, and stage gate project management.

Because this role is deeply integrated into our physical operations, the final stage is an intensive on-site loop at the Richmond facility. During this stage, you will meet with cross-functional stakeholders, including plant managers, operations leads, and safety officers. You should expect a plant tour as part of the evaluation, where interviewers will gauge your situational awareness, safety mindset, and comfort level in an active, industrial setting.

The visual timeline above outlines the typical progression from initial screening to the final on-site panel. Use this to pace your preparation, ensuring you are ready to discuss high-level project management early on, while reserving your deepest technical and safety-oriented examples for the on-site rounds. Note that the on-site loop is intensive and requires physical walkthroughs, so managing your energy and arriving prepared for a manufacturing environment is critical.

To succeed in our interviews, you need to understand exactly how we evaluate your technical and operational competencies. Below are the primary areas of focus.

Process Modeling and Automation Systems

This area is critical because it represents the core technical deliverable of the role. We evaluate your ability to diagnose process deficiencies and translate physical manufacturing needs into precise automation functional descriptions and process datasheets. Strong performance means you can comfortably discuss how you use data to model improvements and update technical documentation.

Be ready to go over:

• Material Balances and P&IDs – How you read, update, and maintain these critical documents to reflect new automation logic.

As a Software Engineer (Project Engineer) at AAK, your day-to-day work is a dynamic mix of desk-based engineering and hands-on plant floor engagement. You will spend a significant portion of your time executing capital projects, which involves developing clear project premises, establishing budgets, and strictly managing schedules. You are the central figure ensuring that the vision for new and existing equipment modifications is carried out from concept to start-up.

Collaboration is at the heart of this role. You will constantly interact with operations to evaluate process schemes from live operating data, diagnosing deficiencies and creating design improvements. When a new facility or equipment line is being planned, you will prepare the process datasheets, update P&IDs, and write the automation functional descriptions that contractors will use to build the systems.

You will also act as the primary technical consultant during plant commissioning. This means you will leave the office environment, put on your hardhat and safety gear, and step onto the manufacturing floor to provide real-time oversight. You will present your process modeling studies and energy efficiency findings to senior management, ensuring that every capital investment aligns with our overarching goal of Making Better Happen™.

To be highly competitive for this position, candidates must possess a unique blend of systems engineering, project management, and physical chemical engineering knowledge.

• Must-have skills – A Bachelor’s degree in engineering (Chemical Engineering is strongly preferred). You must have a minimum of 10 years of experience in project-based engineering with a heavy focus on capital project execution. An excellent, practical understanding of heat transfer, fluid transport, and reaction chemistry is non-negotiable.
• Must-have operational readiness – You must be comfortable working on-site in an active manufacturing plant environment, which includes exposure to loud noises, dust, and wearing required protective safety clothing (hardhat, goggles, appropriate shoes).
• Soft skills – Exceptional written and oral communication skills are required to present studies to management and oversee contractors. You must have a proven track record of successfully meeting strict schedule deadlines.
• Nice-to-have skills – Advanced proficiency in specific process modeling software and deep experience with modern automation protocols will set you apart.

Q: Is there any flexibility for remote work in this role? This is a strictly on-site role located at the Richmond, California manufacturing plant. Because you will be diagnosing physical process deficiencies, overseeing contractors, and participating in plant commissioning, your physical presence on the manufacturing floor is essential.

Q: How deeply will I be tested on chemical engineering principles if my background is in software/systems? You will be tested rigorously. Because our automation systems directly control the filtration, deodorization, and bleaching of plant-based oils, you must demonstrate a strong applied understanding of heat transfer, fluid transport, and reaction chemistry.

Q: What differentiates a successful candidate from an average one? A successful candidate seamlessly bridges the gap between high-level capital strategy and ground-level execution. They can comfortably present a financial forecast to senior management in the morning and troubleshoot a P&ID discrepancy with a contractor on the plant floor in the afternoon.

Q: How long does the interview process typically take? The process from the initial recruiter screen to a final offer typically takes 3 to 5 weeks, depending on the availability of the cross-functional interview panel and scheduling the on-site plant tour.

• Speak the Language of Capital and ROI: Whenever you discuss a technical improvement or a new automation system, tie it directly back to capital strategy. Highlight how your engineering choices improved manufacturing efficiency, saved energy, or reduced schedule deviation.
• Emphasize Safety Above All: You will be working in an environment with heavy machinery, loud noises, and strict PPE requirements. Proactively weave your commitment to industrial safety and compliance into your behavioral answers.
• Master the Stage Gate Framework: If you are not intimately familiar with stage gate methodology for capital investments, review it thoroughly. Interviewers want to see that you respect structured, phased project approvals.
