What is a part time software tester?

Part time software testers are professionals who work limited hours, usually less than full-time, to evaluate and ensure the quality of software applications. They are responsible for identifying bugs, running test cases, and reporting issues to developers. This role is ideal for individuals who need flexible work arrangements or are gaining experience in the software industry. Part time software testers often collaborate with development teams to help improve the functionality and reliability of software products.

What does a part time software tester do?

As a part-time software tester, your job is to use a computer or another electronic device to test a piece of software and help troubleshoot any issues. In this role, you may discuss errors with programmers to help debug the software, document and report each issue you encounter, test recent fixes to verify whether or not they are working as intended, and occasionally provide your opinion on the overall status of the software. Part-time software testers often work from home or as part of a large team. Employers may list this job under names like QA tester or under industry-specific titles like video game tester.

What are the key skills and qualifications needed to thrive as a part time software tester, and why are they important?

To thrive as a Part Time Software Tester, you need a good understanding of software development concepts, attention to detail, and basic programming or scripting knowledge, often supported by a degree or coursework in computer science or a related field. Familiarity with test management tools (like Jira or TestRail), bug tracking systems, and automated testing frameworks is typically required. Strong analytical thinking, effective communication, and adaptability are essential soft skills to identify issues and collaborate with development teams. These skills are crucial for ensuring software quality, meeting project deadlines, and contributing to overall product reliability.

How do part time software testers typically coordinate their work with full-time development teams?

Part-time software testers often collaborate closely with full-time developers and QA teams by attending scheduled stand-ups, using project management tools, and maintaining clear communication through documentation and messaging platforms. Since their working hours may be limited, part-time testers are usually assigned specific test cases or modules and are expected to provide timely feedback on defects and usability issues. Flexibility and proactive communication are key to ensuring that their contributions align with sprint cycles and release timelines, and many organizations support this through well-defined testing processes and frequent check-ins.

Full-time, Part-time

Re-posted 25 days ago

Job description

Shield AI is a venture-backed defense-tech company with the mission of protecting service members and civilians with intelligent systems. Its products include Hivemind autonomy software, V-BAT and X-BAT aircraft, and Aechelon simulation and synthetic reality technologies. With offices and facilities across the U.S., Europe, the Middle East, and Asia-Pacific, Shield AI’s technology actively supports operations worldwide. For more information, visit www.shield.ai. Follow Shield AI on LinkedIn, X, Instagram, and YouTube. 

JOB DESCRIPTION:
The Aircraft Simulation team turns frontier autonomy into mission-ready aircraft. We own the commit-to-flight pipeline—deterministic aircraft and mission simulation, HITL/SITL integration, CI/CD, and tooling for automated flight qualification testing. Our goal is simple: make AI fly—safely, reliably, and fast.
As a Senior Modeling & Simulation Engineer, you will be dedicated to Shield AI’s next-generation aircraft program, contributing to our modeling and simulation tooling pipeline. You’ll design, build, and scale novel aircraft subsystem models, develop infrastructure that enables automated testing for our XBAT product line, and perform verification and validation of simulation pipelines. You will also conduct system performance analysis to evaluate expected and actual flight and mission performance using simulation tools and publish results for consumption by customers.
What You'll Do
  • Develop models and infrastructure for the integrated simulation pipeline in C++
  • Design deterministic, high-performance simulation tools capable of faster-than-real-time execution for development, testing, and release. 
  • Implement test scenarios and write unit, system, and regression tests. 
  • Collaborate across autonomy, embedded, GNC, and test engineering to ensure the simulation mirrors real aircraft behavior and mission scenarios. 
  • Contribute to platform-agnostic simulation tooling to accelerate future development efforts 
  • Perform verification and validation (V&V) analysis activities on model tools. 
  • Conduct system performance analysis and generate reports and visualizations. 
  • Utilize best practices in C++, simulation architecture, and performance engineering.
Required Qualifications
  • BS or MS in Computer Science, Aerospace, Robotics, or related field. 
  • 5+ years of experience in software development, with emphasis on modern C++ (C++17 or later) and performance optimization. 
  • Strong understanding of rigid-body dynamics, kinematics, and basic flight and sensor mechanics. 
  • Proven experience developing or integrating simulation systems for robotics, aerospace, or autonomous systems. 
  • Ability to debug complex build and runtime environments (CMake, CPM, package management, logging, & profiling tools). 
  • Experience with software testing tools (GTest, etc.) 
  • Experience with model V&V. 
  • Strong collaboration and communication skills across software, hardware, and systems disciplines.
  • Ability to obtain a S//SAR level security clearance desired.
Preferred Qualifications
  • Grasp of real-time and deterministic software design, including multi-threading, synchronization, and memory management. 
  • Experience with DevOps-integrated simulation workflows, including CI/CD and automated hardware testing environments.
  • Working knowledge of Python for data analysis, test automation, or simulation orchestration. 
  • Familiarity with aircraft and flight physics modeling.
