At AAK, the Software Engineer role operates in a highly specialized manufacturing context, often functioning internally under the title of Project Engineer. Our story goes back more than 150 years to the southern coast of Scandinavia, and today we are the world’s leading specialist producer of plant-based oils. In this role, you are not just writing code; you are designing and implementing the automation functional descriptions, process modeling, and flow control systems that keep our manufacturing facilities running at peak efficiency.

Your impact in this position is tangible and global. The systems and processes you optimize directly influence the quality of products consumers love—from making chocolate extra-creamy to putting the crunch into croissants. Operating out of our Richmond, California manufacturing plant, you will bridge the gap between software-driven automation and physical chemical engineering processes like filtration, deodorization, and bleaching. Everything we do is about Making Better Happen™, and your technical leadership ensures our production remains healthier, higher quality, and better for the planet.

This is a senior, heavily cross-functional role requiring a deep understanding of capital project execution. You will guide engineering and construction contractors, oversee plant commissioning, and manage the technical scope of multi-million-dollar facility upgrades. Expect a dynamic, hands-on environment where your software and systems engineering expertise directly translates into physical manufacturing success.

The questions below represent the patterns and themes you will encounter during your interviews. They are designed to test the intersection of your systems knowledge, project management skills, and engineering fundamentals. Do not memorize answers; instead, use these to practice structuring your experiences into clear, quantifiable narratives.

Process Engineering & Automation

These questions test your ability to translate physical manufacturing needs into technical documentation and automated systems.

• Walk me through how you develop an automation functional description for a new piece of processing equipment.
• How do you verify that your material balances and P&IDs are completely synchronized before a project moves to the execution phase?

Preparing for an interview at AAK requires a strategic approach. We evaluate candidates not just on their technical acumen, but on their ability to apply that knowledge within a complex, physical manufacturing environment.

Here are the key evaluation criteria you should focus on:

• Process Modeling & Automation Expertise – We assess your ability to design improved processes, update Piping and Instrumentation Diagrams (P&IDs), and write robust automation functional descriptions. You can demonstrate strength here by sharing specific examples of how your systems improved manufacturing or energy efficiency.
• Capital Project Execution – This role involves managing significant financial investments. Interviewers will look for your track record in controlling scope, managing schedule deviations, and utilizing stage gate methodologies to bring capital investments to completion.
• Engineering Fundamentals – Because our software and automation systems control physical chemical processes, you will be evaluated on your understanding of heat transfer, fluid transport, and reaction chemistry. Strong candidates seamlessly bridge software logic with these physical realities.
• Cross-Functional Leadership – You must successfully guide external contractors and internal stakeholders. We evaluate your communication skills and your ability to present highly technical process studies to senior management in a clear, actionable way.

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.
• Process Flow Control – Your approach to designing systems for filtration, deodorization, and bleaching.
• Data-Driven Diagnostics – How you evaluate process schemes using live operating data to identify bottlenecks.
• Advanced concepts (less common) – Integrating legacy machinery with modern automation protocols, or predictive modeling for energy efficiency.

Example questions or scenarios:

• "Walk me through a time you identified a process deficiency using operating data and designed an automation improvement to solve it."
• "How do you ensure your automation functional descriptions align perfectly with the updated P&IDs for a new facility start-up?"

Capital Project Management

As a key driver of capital strategy, your ability to manage project finances and schedules is heavily scrutinized. We evaluate your familiarity with stage gate methodologies and your strict control over scope creep. A strong candidate demonstrates a history of bringing complex, multi-million-dollar projects to completion on time and within budget.

Be ready to go over:

• Stage Gate Methodology – Your experience navigating projects through structured approval phases.
• Scope and Schedule Control – Techniques you use to prevent schedule deviation and manage contractor deliverables.
• Stakeholder Reporting – How you forecast current activities and present capital project reports to senior management.

Example questions or scenarios:

• "Describe a capital project where the scope began to expand beyond the initial budget. How did you manage the stakeholders and contractors to reel it back in?"
• "Explain your process for developing clear project premises, budgets, and detailed schedules with cross-functional teams."

Engineering Fundamentals

Because our automation controls plant-based oil production, a pure software background is not enough. We evaluate your foundational engineering knowledge. You must demonstrate an excellent understanding of the physical laws governing our manufacturing floor.
