What is a Software Engineer at Novo Nordisk?

As a Software Engineer at Novo Nordisk, your work bridges the gap between digital innovation and life-saving physical manufacturing. Unlike traditional tech companies where software exists purely in the cloud, software engineering here is deeply integrated with automation, pharmaceutical production, and complex supply chains. You are building, maintaining, and optimizing the systems that allow us to manufacture critical treatments—such as our insulin and GLP-1 products—safely and at a massive scale.

Your impact in this position is profound. Whether you are working as an API Manufacturing Specialist in Boulder, an Automation Technician in Clayton, or supporting cleaning and packaging engineering processes in West Lebanon, your code directly influences product quality and patient safety. You will develop automated workflows, integrate complex APIs for supplier management, and ensure that our manufacturing execution systems operate flawlessly under strict regulatory standards.

This role requires a unique blend of traditional software development and an understanding of industrial automation. You will face complex challenges involving real-time data processing, legacy system integration, and rigorous compliance documentation. If you are passionate about writing software that has a tangible, life-changing output in the real world, this role offers an unparalleled opportunity to drive strategic influence within a global pharmaceutical leader.

Common Interview Questions

Getting Ready for Your Interviews

Preparing for an interview at Novo Nordisk requires a strategic mindset. Your interviewers are not just looking for someone who can write clean code; they are looking for an engineer who understands how that code interacts with physical processes, quality assurance protocols, and cross-functional teams.

Focus your preparation on the following key evaluation criteria:

Technical and Domain Expertise – You will be evaluated on your core software engineering skills, as well as your familiarity with automation, system integration, and API development. Strong candidates demonstrate an ability to apply software principles to manufacturing and industrial environments.

Problem-Solving in Regulated Environments – Interviewers want to see how you approach complex technical issues while navigating strict compliance frameworks like Good Manufacturing Practice (GMP). You must show that you can innovate without compromising on safety, quality, or regulatory standards.

Cross-Functional Collaboration – Software Engineers here rarely work in silos. You will be assessed on your ability to communicate technical concepts to non-technical stakeholders, including process engineers, packaging specialists, and quality assurance teams.

Culture Fit and The Novo Nordisk Way – We are a deeply patient-centric organization. You will be evaluated on your alignment with our core values, your commitment to continuous improvement, and your ability to thrive in a highly collaborative, purpose-driven culture.

Interview Process Overview

The interview process for a Software Engineer at Novo Nordisk is thorough and highly structured. Because our software systems impact patient health, our hiring teams take the time to ensure you possess both the technical rigor and the cultural alignment required for the role. The process typically begins with an initial recruiter screen to discuss your background, location preferences, and high-level technical experience.

Following the recruiter screen, you will move to a technical interview with a hiring manager or a senior engineer. This round focuses heavily on your past projects, your understanding of API integrations, and your familiarity with automated systems. You should expect a mix of technical probing and behavioral questions designed to see how you handle real-world manufacturing software challenges.

The final stage is a comprehensive panel interview, which may be conducted virtually or onsite at one of our manufacturing hubs. This panel usually consists of cross-functional team members, including software engineers, automation specialists, and quality assurance managers. The panel will dive deeply into system design, problem-solving scenarios, and your ability to embody The Novo Nordisk Way.

This visual timeline outlines the typical progression of your interview stages, from the initial recruiter screen to the final panel rounds. Use this to pace your preparation, ensuring you are ready for both the deep technical discussions and the cross-functional behavioral assessments that occur later in the process. Keep in mind that specific stages may vary slightly depending on your location and the exact focus of your team.

Deep Dive into Evaluation Areas

Automation and Systems Integration

Because Novo Nordisk relies heavily on automated manufacturing, your ability to integrate software with physical systems is a primary focus. Interviewers will assess your understanding of how data flows between manufacturing equipment, supervisory control systems, and enterprise databases. Strong performance means you can confidently discuss bridging IT (Information Technology) and OT (Operational Technology).

Be ready to go over:

• API Development and Management – Designing and securing APIs that connect supplier management systems with internal manufacturing databases.
• SCADA and PLC Concepts – Understanding how software interacts with programmable logic controllers and supervisory systems on the factory floor.
• Data Pipelines – Moving high-volume, real-time data from packaging and cleaning systems into centralized analytics platforms.
• Advanced concepts (less common) –
  • Industrial Internet of Things (IIoT) protocols (e.g., MQTT, OPC UA).
  • Real-time operating systems (RTOS) and deterministic networking.

Example questions or scenarios:

• "Walk me through how you would design an API to pull real-time sensor data from a manufacturing line."
• "Describe a time you had to integrate a modern software application with a legacy hardware system."
• "How would you handle a scenario where a critical data feed from a packaging machine suddenly drops?"

Quality, Compliance, and GMP

In the pharmaceutical industry, software bugs can lead to product recalls or patient harm. You will be heavily evaluated on your understanding of quality assurance and compliance. Interviewers want to see that you prioritize testing, documentation, and validation just as much as feature development. Strong candidates seamlessly weave quality considerations into their technical answers.

Be ready to go over:

• Software Development Life Cycle (SDLC) – Following rigorous, documented processes from requirements gathering to deployment.
• Good Manufacturing Practice (GMP) – Understanding the regulatory standards that govern pharmaceutical production.
• Testing and Validation – Implementing automated testing, unit tests, and computer system validation (CSV) protocols.
• Advanced concepts (less common) –
  • FDA 21 CFR Part 11 compliance (electronic records and signatures).
  • GAMP 5 (Good Automated Manufacturing Practice) guidelines.

Example questions or scenarios:

• "How do you ensure your code is fully traceable from requirement to deployment?"
• "Tell me about a time you found a critical bug late in the development cycle. How did you handle the documentation and resolution?"
• "What is your approach to writing software that will be audited by regulatory bodies?"

Cross-Functional Problem Solving

As a Software Engineer, you will collaborate with cleaning support teams, packaging engineers, and API manufacturing specialists. Interviewers will test your ability to translate physical engineering problems into software solutions. A strong performance in this area demonstrates empathy for the end-user (often a factory operator or process engineer) and a structured approach to troubleshooting.

Be ready to go over:

• Requirements Gathering – Translating vague requests from non-software teams into precise technical specifications.
• Root Cause Analysis – Systematically diagnosing complex issues that span both software and physical machinery.
• Stakeholder Communication – Explaining technical limitations or architectural decisions to business leaders and operational staff.
• Advanced concepts (less common) –
  • Lean manufacturing principles and Six Sigma methodologies.
  • Designing user interfaces (UI/HMI) specifically for gloved operators in cleanrooms.

Example questions or scenarios:

• "Tell me about a time you had to explain a complex technical issue to a non-technical stakeholder."
• "An operator reports that the automated cleaning system software is freezing. Walk me through your troubleshooting steps."
• "How do you prioritize feature requests when multiple engineering teams are demanding your attention?"
