Accessing CAD data and material specifications from the PLM system, manually uploading final reports and key results.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Simulation Methodology (e.g., solver choice, element type) No independent decision. Execute based on senior engineer's instruction. Escalate if instructions are unclear or seem inappropriate. Propose and justify choices for routine problems. Consult senior engineer for non-standard cases. Make and own technical decisions within project scope. Seek input from Lead/Principal for cross-project impact.
CAD Model De-featuring Strategy Follow established guidelines and senior engineer's specific instructions. Escalate if unsure what to remove. Independently decide on de-featuring for standard components. Consult senior engineer for complex assemblies. Define de-featuring guidelines and best practices for the team. Review junior engineer's strategies.
Mesh Quality & Refinement Aim to meet defined quality metrics. Escalate if struggling to achieve quality or if a specific area needs refinement. Independently decide on meshing strategy for component-level models. Justify refinement choices. Set mesh quality standards and develop advanced meshing techniques. Troubleshoot complex meshing failures.
Interpretation of Unexpected Results Flag immediately to senior engineer. Do not proceed without guidance. Provide all relevant input/output files. Investigate potential causes (e.g., boundary conditions, material properties). Propose hypotheses and solutions to senior engineer. Diagnose root cause and propose corrective actions. Validate findings and communicate implications to design team.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Model Setup Time (Standard Tasks)
The time it takes from receiving a CAD model to successfully launching a pre-defined simulation run.
Target · Reduce setup time by 20% over 6 months for routine tasks.

If a basic thermal analysis usually takes 4 hours, you should be able to complete it in around 3 hours after 6 months of practice.

Accuracy on Benchmark Problems
How close your simulation results are to known analytical solutions or simple test cases.
Target · Achieve less than 10% deviation from analytical solutions on 80% of benchmark problems.

When simulating a simple cantilever beam, your calculated deflection should be within 5% of the theoretical value.

Task Throughput & Completion Rate
The number of assigned simulation preparation or post-processing tasks you complete within agreed deadlines.
Target · Successfully complete 5-8 standard analysis support requests per sprint (usually two weeks).

In a two-week sprint, you might prepare 6 CAD models for meshing, run 2 post-processing scripts, and document 3 simulation setups.

Adherence to Best Practices & Procedures
How well you follow our established simulation workflows, naming conventions, and quality checks.
  • Your simulation files are always organised correctly, your input decks follow the template, and you consistently use the right material properties. Your Senior Engineer rarely needs to correct fundamental procedural errors.
Quality of Documentation & Reporting Support
The clarity and completeness of the notes, screenshots, and data you provide to support simulation reports.
  • The data you prepare for reports is easy to understand, well-labelled, and requires minimal editing from your Senior Engineer. You proactively add context where needed, even if not explicitly asked.
Proactive Learning & Asking Good Questions
Your initiative in seeking to understand the 'why' behind tasks and asking insightful questions that help you learn faster.
  • You're not just following instructions
  • you're asking 'why do we do it this way?' or 'what would happen if I changed this parameter?'. You bring up challenges you've faced and suggest ways to improve your own process, rather than just waiting to be told what to do next.
Responsiveness & Communication
How quickly and clearly you communicate updates, roadblocks, or questions to your Senior Engineer and team.
  • You respond to messages promptly, give clear updates on task progress, and flag issues early rather than letting them become bigger problems. You don't leave people guessing about where you're at.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Complex Puzzles

You'll spend a good chunk of your day trying to figure out why a mesh isn't clean, or why a simulation won't converge. It's like a daily logic puzzle, but with real-world engineering implications.

Spending an afternoon tracking down a tiny geometric error in a CAD model that was causing meshing failures, and feeling a real sense of satisfaction when you finally fix it.

Continuous Learning & Skill Development

This role is a learning marathon. You'll be constantly picking up new software features, understanding different physics theories, and refining your approach to problem-solving. Every day is a school day, but a practical one.

Successfully applying a new meshing technique you learned from a tutorial to a tricky part, and seeing it improve your simulation's stability.

Contributing to Tangible Products

You'll be working on simulations that directly feed into the design of our actual products. You'll see the CAD models you clean up eventually become physical parts, and know your work helped make them better.

Seeing a product launched that you helped simulate, knowing your input contributed to its performance and reliability.

What frustrates people
  • The CAD Cleanup Black Hole: You'll get CAD models from design engineers that are far too detailed or 'dirty', requiring hours of manual de-featuring before you can even think about meshing. It's tedious, but necessary.
  • The 'Wait and Crash' Cycle: You'll set up a simulation, let it run for hours, only for it to crash near the end due to a subtle instability. Then you have to figure out why and start again.
  • The 'Magic Button' Misconception: People outside the team often think simulation is just a magic button that gives perfect answers. You'll hear requests for 'quick simulations' that actually take days, and you'll have to explain the limitations.
  • Explaining Meshes to Management: Trying to justify why a project is delayed because of 'poor mesh quality' or 'convergence issues' to someone who just wants to see the final pretty picture can be frustrating.
  • Repetitive Learning Tasks: Sometimes you'll do the same basic setup or post-processing task several times as you learn, which can feel a bit monotonous before you master it.
What this role does not give you
  • Immediate decision-making authority: You'll be executing, not deciding the overall simulation strategy or project direction.
  • High-level strategic influence: Your focus is on the technical details and learning, not shaping the long-term vision of the department.
  • A perfectly clean, predictable workflow: Expect messy data, unexpected software crashes, and iterative problem-solving.
  • Constant external client interaction: Most of your work will be internal, supporting your team and other engineering departments.

8Who you work with

Your main impact will be ensuring the foundational data and models for our simulations are correct. Think of it like building the strong base for a house—if you do your bit well, the whole structure is more stable and reliable. You'll help us speed up design cycles and make sure our product decisions are based on solid virtual testing, ultimately saving the company time and money.

Inside the business
  • Your Senior Simulation Engineer (for guidance and task allocation)
  • Other Simulation Engineers (for learning and collaboration)
  • Product Design team (you'll get models from them, they'll use your results)
  • Test & Validation team (you'll help compare simulation results to their real-world tests)
Outside the business
  • Software vendors (you might interact with support if you hit a bug)
  • Academic partners (occasionally, if we're working on research projects)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • A degree (or equivalent experience) in Mechanical Engineering, Aeronautical Engineering, Civil Engineering, or a related scientific discipline.
  • Demonstrable experience (e.g., through university projects, internships, or personal projects) with at least one commercial FEA or CFD software package.
  • A foundational understanding of engineering mechanics, materials science, and numerical methods.
  • Basic proficiency in a programming language, preferably Python, for scripting and data manipulation.
  • A genuine curiosity about how things work and a desire to use simulation to understand and improve them.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Meshing Techniques

As models become more complex and accuracy demands increase, you'll need to move beyond basic meshing. Knowing how to create high-quality, efficient meshes for challenging geometries is a bottleneck for many teams.

Hex-Meshing · Boundary Layer Meshing · Mesh Morphing

  • This quarter: Take an online course or tutorial specifically on advanced meshing techniques in your primary software.
  • Next quarter: Identify one complex component in a current project and try to apply an advanced meshing technique, comparing its performance to standard methods.
  • Month 6: Present your findings on the benefits and challenges of advanced meshing to your team.
  • Ongoing: Seek out opportunities to work on projects that involve challenging geometries and meshing requirements.

Quick win: Ask your Senior Engineer for a 'difficult' CAD model to practice de-featuring and meshing on in your spare time. The more practice, the better.

Understanding Numerical Methods (Foundational)

To truly troubleshoot complex convergence issues or interpret solver warnings, you need to understand what's happening 'under the hood'. This knowledge will make you a much more effective and independent engineer.

Finite Volume / Finite Difference Methods · Explicit vs. Implicit Time Integration · Convergence Criteria

  • This quarter: Read introductory chapters on numerical methods in a relevant textbook (your Senior Engineer can recommend one).
  • Next quarter: When a simulation fails, try to link the error message back to a specific numerical method concept you've learned.
  • Month 6: Discuss with your Senior Engineer how different solver settings relate to numerical stability and accuracy.
  • Ongoing: Attend webinars or workshops on the underlying theory of your simulation software.

Quick win: When you encounter a 'convergence issue', don't just restart. Look up the specific error message and try to understand the numerical reason behind it before asking for help.

11Staying current once you are in

What people here do to keep up
  • Attend webinars and online tutorials offered by simulation software vendors (e.g., ANSYS, Abaqus). They often have great free content for beginners.
  • Join relevant engineering communities or forums (e.g., LinkedIn groups, Reddit communities for CAE) to learn from others and ask questions.
  • Read technical blogs and articles on simulation best practices and new developments. Staying current is key.
  • Take advantage of any internal training programmes or mentorship opportunities we offer. We're invested in your growth.
  • Work on personal simulation projects outside of work to explore new software features or physics problems that interest you.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, a lot of simulation work can be a bit repetitive and time-consuming. But what if you could offload some of that grunt work to AI? We're not talking about replacing you, far from it. We're talking about giving you superpowers to get more done, learn faster, and focus on the really interesting engineering challenges.

Our team is actively exploring and integrating AI tools into our daily simulation workflows. As an Associate Simulation Engineer, you'll be at the forefront of learning how to use these smart assistants to make your life easier. Think of it as having a super-efficient intern who handles the tedious bits, freeing you up to understand the physics and the engineering. Here's a peek at how AI can actually help you day-to-day:

Automated Geometry Cleanup

Imagine taking a complex CAD model with hundreds of tiny, irrelevant features (like small fillets or logos) and letting an AI tool automatically 'de-feature' it for you. This saves you hours of tedious manual work, getting you to the meshing stage much faster. You'll still review it, of course, but the heavy lifting is done.

Surrogate Model Prediction Support

While you won't be building these yet, you'll learn how to use AI-trained 'surrogate models' to get near-instant predictions for minor design changes. Instead of waiting hours for a full simulation, you can quickly check a design iteration, helping you understand trends and inform your next full simulation setup.

Intelligent Literature Review

When you're trying to understand a new turbulence model or numerical method, AI research assistants can scan thousands of academic papers. They'll give you concise summaries and point you to the most relevant studies, helping you learn faster and get up to speed on complex topics without drowning in research.

Executive Summary Generation Support

After you've done all your post-processing, you can feed your key plots and data into an AI writer. It can help you draft a clear, concise summary of your findings, tailored for a non-technical audience. This means less time struggling with words and more time focusing on the engineering insights.
