What is a Software Engineer at Unilever?

At Unilever, the role of a Software Engineer—often titled internally as an IT Engineer or Digital Engineer depending on the specific team—is fundamentally different from a pure software development role at a tech-native firm. Here, you are a critical driver of Digital Transformation and Operational Excellence. You are not just writing code; you are integrating complex digital infrastructures that power the manufacturing and distribution of brands used by 3.4 billion people every day, such as Dove, Hellmann’s, and Ben & Jerry’s.

This position sits at the intersection of Information Technology (IT) and Operational Technology (OT). You will likely be responsible for designing, deploying, and maintaining the digital backbone of our manufacturing sites and business units. This involves working with cloud platforms (Azure/AWS), data visualization tools (Power BI), networking infrastructure, and industrial control systems. Your work directly impacts our ability to innovate, maintain safety standards, and deliver on our massive sustainability goals.

Candidates should expect a role that requires high adaptability. You might spend your morning scripting automation in Python or PowerShell to optimize a server update, and your afternoon collaborating with Quality Engineers to digitize a food safety workflow using SAP and IoT devices. If you are passionate about applying technology to solve tangible, real-world supply chain and manufacturing challenges, this role offers immense strategic influence.

Getting Ready for Your Interviews

Preparation for Unilever requires a shift in mindset. While technical competency is non-negotiable, we place equal weight on your ability to apply that technology to business problems and your alignment with our core values. You should approach your preparation holistically, focusing on how your technical skills drive efficiency and sustainability.

You will be evaluated on the following key criteria:

Digital & Operational Fluency We assess your ability to bridge the gap between software and hardware. You need to demonstrate not just coding or system administration skills, but an understanding of how these systems function in a 24/7 manufacturing environment where downtime is costly.

Unilever Standards of Leadership This is our internal behavioral framework. We evaluate how you demonstrate a Growth Mindset, Consumer Focus, and a Bias for Action. We look for candidates who take ownership of problems and drive solutions without waiting for permission.

Problem Solving & Analytical Thinking Beyond algorithms, we test your ability to troubleshoot complex system issues. You must show how you use data to diagnose root causes—whether it is a network bottleneck, a server failure, or a gap in a quality assurance process—and implement long-term fixes.

Stakeholder Communication You will work with non-technical partners, from plant managers to marketing leads. We evaluate your ability to translate complex technical concepts (like cybersecurity protocols or cloud architecture) into clear, actionable business language.

Interview Process Overview

The interview process for engineering roles at Unilever is designed to be thorough yet practical. It typically moves at a steady pace, often taking 3 to 5 weeks from initial contact to offer. The process generally begins with a digital assessment or a recruiter screen, followed by a series of interviews that test both your technical capabilities and your cultural fit.

Unilever is unique in its heavy reliance on behavioral consistency. We use structured interviewing techniques to ensure every candidate is judged fairly against the same competencies. You should expect a mix of traditional one-on-one interviews and panel discussions. For technical roles, you may encounter a "Digital Interview" stage early on, utilizing platforms like HireVue, where you record answers to pre-set questions regarding your experience and situational judgment.

Following the initial screens, the process culminates in a "Discovery Center" day or a final round panel. In these sessions, you will likely face deep-dive technical questions regarding infrastructure, scripting, and system design, alongside rigorous behavioral questions based on the STAR method (Situation, Task, Action, Result). Unlike tech startups that may focus on abstract coding puzzles, our questions are contextual—expect scenarios involving factory downtime, data integration challenges, or cybersecurity threats.

This timeline illustrates the typical progression for a candidate. Note that the "Technical & Behavioral Screen" is often the most critical filter; this is where we determine if you have the practical skills to handle the operational reality of our sites. Use this visual to plan your preparation, ensuring you have your behavioral stories polished before the final rounds.
