Technical Depth and Hardware Integration

This area evaluates your ability to build software that interacts with the physical world. Strong candidates show a clear understanding of how software signals translate into mechanical actions.

• C/C++ and Linux – Proficiency in these is non-negotiable for system-level work.
• Hardware Communication – Understanding protocols and interfaces for measurement hardware.
• Troubleshooting – Your systematic approach to resolving performance bottlenecks.

Architectural Design and Best Practices

You are expected to design for maintainability. This means writing code that is not just functional, but also documentable and scalable.

• Documentation – Using tools like Confluence to keep the team aligned.
• Version Control – Mastery of Git and modern deployment workflows.
• Code Quality – Adhering to standards that ensure system reliability over long periods.

As a Software Engineer, your primary objective is the maintenance and evolution of the Data Acquisition and Control System (DACS). You will be expected to spend significant time ensuring that this system remains the industry standard for aerospace testing. This involves not only writing new features but also rigorously testing how they integrate with existing hardware.

Collaboration is a core pillar of your responsibilities. You will frequently interface with hardware engineers to ensure that the software is capturing the necessary data with high precision. Furthermore, you will be expected to maintain comprehensive system documentation, ensuring that the team can scale effectively. You should expect to participate in code reviews and architectural discussions that emphasize long-term system stability over quick fixes.

A competitive candidate for this position will possess a mix of academic training and practical, hands-on experience in industrial or aerospace environments.

• Must-have skills:
  • 7+ years of experience in computer programming or equivalent.
  • Deep experience with C, C++, or Python.
  • Solid development background for the Linux operating system.
  • Ability to interpret wiring diagrams and mechanical drawings.
• Nice-to-have skills:
  • Prior experience in jet engine testing or similar high-stakes data acquisition fields.
  • Familiarity with Labview or similar instrumentation software.
  • Experience with Atlassian tools (Jira/Confluence) for project management.

Q: How difficult are the technical interviews? A: Candidates generally find the technical portion to be average in difficulty, focusing more on your actual experience and problem-solving methodology than on "gotcha" algorithm questions. Be prepared to explain the "why" behind your technical decisions.

Q: Is there a take-home assignment? A: Some processes include a take-home portion followed by a presentation. Treat this as a showcase of your best work and your ability to communicate technical requirements clearly to stakeholders.

Q: What is the "Be Calspan" culture like? A: It is a culture that emphasizes accountability and innovation. You will be expected to take ownership of your tasks and contribute to a supportive, highly professional team environment.

Q: How long does the process usually take? A: The process can be quite efficient, with some candidates receiving an offer within 3 to 4 weeks, though this can vary based on internal scheduling.

• Prepare for the "Why": Don't just list what you did; explain why you chose a specific architecture or language for a project.
• Highlight Mentorship: If you are applying for a senior role, be ready with specific stories about how you helped other engineers grow.
• Align with Values: Research the "Be Calspan" values and have personal anecdotes ready that demonstrate how you have been "Inclusive," "Accountable," and "Innovative."
• Manage Expectations: Be prepared to discuss your preferred work environment, as some roles may involve different shifts or specific on-site requirements.
