Stirling Dynamics Software Engineer interview questions & guide 2026

The following questions are representative of the patterns observed in our interview process. They are designed to test your technical depth, your ability to apply theoretical knowledge to physical systems, and your problem-solving process.

Technical Physics & Modeling

These questions assess your ability to translate physical scenarios into mathematical and computational models.

• Talk us through the general process you would use to model the physics of a submarine in a specific configuration.
• A flywheel with a speed of 30 rad/s needs to be stopped; what calculations are required and what measurements do you need?

Preparation at Stirling Dynamics requires more than just brushing up on coding syntax; it requires a mindset geared toward engineering rigor. You should be prepared to discuss your projects in technical detail, explaining not just "how" you built something, but "why" you chose a specific mathematical or algorithmic approach.

Technical Domain Knowledge – You must demonstrate a solid grasp of physics, control theory, and MATLAB or similar simulation environments. Interviewers will look for your ability to define parameters, state your assumptions clearly, and derive solutions from first principles.

Problem-Solving Approach – When faced with an open-ended scenario, do not jump straight to an answer. Structure your thoughts, identify the missing variables, and communicate your logic to the interviewer as you go. They are looking for a collaborative partner who can navigate technical ambiguity.

Engineering Communication – You will be expected to explain complex concepts clearly. Practice describing your past projects, focusing on the technical challenges you faced and the specific engineering decisions you made to overcome them.

The interview process at Stirling Dynamics is designed to evaluate both your technical competence and your fit within a highly specialized team. You can expect a rigorous assessment that moves from high-level screening to in-depth technical examination. The process typically begins with a phone screen to align on your experience and background, followed by one or more technical stages that may involve whiteboard sessions, code reviews, or physics-based case studies.

The philosophy here is "challenging but fair." You will interact with various team members, and the process is intended to simulate the collaborative, peer-reviewed nature of the actual work. Be prepared for a high-intensity environment where your reasoning is scrutinized as much as your final answer.

This timeline illustrates the progression from initial screening to technical deep dives. Use this to pace your preparation; ensure you have reviewed your core technical fundamentals before the later, more complex simulation and modeling rounds.

Physics & Mathematical Modeling

This is the cornerstone of the role. You are expected to apply physics principles to real-world scenarios. Strong performance involves identifying the correct governing equations and articulating the physical constraints of the system.

Be ready to go over:

• Rotational Dynamics – Understanding inertia, torque, and angular velocity.
• System Stability – Interpreting responses and analyzing system behavior over time.

As a Software Engineer, your daily life revolves around the lifecycle of modeling and simulation. You will spend significant time developing and refining models that predict the behavior of complex hardware. This involves writing efficient code, performing sensitivity analyses, and ensuring that your simulations accurately reflect physical reality.

You will work closely with systems engineers to integrate your software modules into larger project architectures. Collaboration is key; you will often participate in peer reviews of code and design documents. Typical initiatives include optimizing control algorithms for better performance, creating automated testing suites for simulation models, and documenting the physical assumptions underlying your software tools.

A strong candidate for this role possesses a blend of high-level academic theory and practical software engineering capability. We value candidates who can bridge the gap between abstract mathematics and functional, robust code.

• Must-have skills: Proficient in MATLAB or Simulink, strong foundation in classical control theory, and experience with physics-based modeling.
• Nice-to-have skills: Experience with version control systems (e.g., Git), familiarity with C++ or Python, and prior exposure to aerospace or marine engineering projects.
• Experience level: We look for individuals who have demonstrated their ability to own a technical problem from definition to resolution, whether through academic research, internships, or professional roles.

Q: How long does the hiring process usually take? The timeline varies, but from initial contact to a final decision, it typically spans a few weeks. The process is thorough, so expect multiple interactions with the engineering team.

Q: What is the best way to prepare for the technical interview? Focus on your fundamentals. Review your university-level physics and control theory notes, and be prepared to talk through your past projects in detail. Practice explaining your logic out loud.

Q: What differentiates successful candidates? Successful candidates are those who ask clarifying questions before diving into calculations. They show that they think like engineers—identifying assumptions, checking for edge cases, and communicating their thought process clearly.

Q: Is this role fully remote? Most roles are based in our offices (e.g., Bristol), as the work often requires close collaboration with hardware teams and access to specialized systems.

• Own your answers: If you are unsure about a specific variable or formula, explain your process for finding the answer rather than guessing.
• Prepare your stories: Use the STAR method (Situation, Task, Action, Result) to frame your behavioral responses, even for technical challenges.
• Be curious: We appreciate candidates who ask thoughtful questions about our current projects, the challenges we face, and the team's culture.
• Stay calm under pressure: The interview is meant to be challenging. If you feel stuck, take a breath, explain your current line of thinking, and ask for a hint if needed.

The Software Engineer position at Stirling Dynamics offers a unique opportunity to apply your technical skills to high-stakes engineering challenges. By focusing on your fundamental physics, control theory, and clear communication, you will be well-positioned to succeed in our rigorous evaluation process. Preparation is your greatest advantage; take the time to review your core competencies and be ready to articulate your engineering process.
