What do we need 

We are seeking an experienced Senior Software Engineer to our M-Star team. M-Star is modern computational fluid dynamics (CFD) software that provides first-principles modeling tools for scientists and engineers, generating predictions that are functionally indistinguishable from measured data. 

As the Principal Software Engineer you will maintain and enhance our cross-platform desktop GUI applications and cloud-based infrastructure. This role combines C++ desktop development, Python API enhancement, CI/build system ownership, and AWS-based deployment and licensing system support. The engineer should have strong experience with technical software. This job involves the full software lifecycle: from user interface to backend infrastructure.
You will work in a small yet highly effective and efficient specialised team,  who deliver world class CFD software to multiple industries including Life Sciences, Chemical Material, Industrial and much more. In this role will work alongside colleagues who have the brightest minds, holding PhDs and who regularly write research papers and speak at conferences. The opportunity to learn is vast 

In this role you will get to: 

Desktop Application & API Development 

• Maintain and enhance cross-platform desktop GUI applications (Windows/Linux)
• Develop and extend a Python-based API that integrates with the core application
• Support user workflows in technically complex software environments (e.g., 3D CAD, CFD)
• Ensure performance, stability, and usability of engineering-focused GUI tools. 

Build, CI, and Licensing Systems 

• Maintain and operate the software build server and continuous integration pipelines
• Manage release processes and versioned software distribution
• Support and maintain license control systems and related backend services. 

Cloud Infrastructure & Operations 

• Maintain AWS-based software distribution and business operations systems
• Manage and configure AWS services, including:
  • EC2, RDS, S3, ECR
  • IAM, WAF, CloudFront
  • CloudTrail, Security Lake

Ensure security, scalability, and reliability of cloud infrastructure. 

• Support operational tooling across AWS and other cloud providers. 

We are looking for people who have  15+ years of professional software development experience with an education or working experience in Background in engineering, scientific computing, or simulation software. .  You will be a highly advanced software engineer typically beginning to become hyper-focused/specialised, a team member who makes important product decisions regarding direction and scope and be comfortable acting as the single point for engineering within MStar 

The key skills we are looking for 

• Strong C++ development background 
• Advanced level in developing desktop GUI applications for technical or scientific software
• Python for API development and automation
• Familiarity with CI/build systems and release engineering
• Hands-on experience managing AWS infrastructure and services
• Experience with 3D CAD or Computational Fluid Dynamics (CFD) software environments
• Comfortable working across the full stack: GUI, API, infrastructure, and operations

You may also have 

• Experience with software licensing systems 
• Familiarity with cross-platform frameworks (e.g., Qt)
• Knowledge of security best practices for cloud deployments
