Entry Level Simulation Software Engineer information

What does an Entry Level Simulation Software Engineer do?

An Entry Level Simulation Software Engineer develops and tests software that models real-world systems, such as physical processes, engineering designs, or virtual environments. They typically work under the guidance of senior engineers to write code, run simulations, analyze results, and troubleshoot issues. Their work helps organizations predict system behavior, optimize designs, and reduce the need for costly physical prototypes. This role often involves programming, understanding mathematical models, and collaborating with other engineering teams.

What are some common challenges faced by entry level simulation software engineers, and how can they be overcome?

Entry level simulation software engineers often encounter challenges such as understanding complex simulation models, learning industry-specific tools, and collaborating with multidisciplinary teams. To overcome these hurdles, it's helpful to actively seek mentorship from senior engineers, participate in team meetings to gain context, and dedicate time to hands-on practice with simulation tools. Regular communication with team members and taking advantage of available documentation can also accelerate learning and integration into the workflow.

What are the key skills and qualifications needed to thrive as an Entry Level Simulation Software Engineer, and why are they important?

To thrive as an Entry Level Simulation Software Engineer, you need a solid background in computer science, mathematics, and programming languages such as C++, Python, or Java, typically supported by a relevant degree. Familiarity with simulation frameworks, modeling tools (like MATLAB or Simulink), and version control systems (such as Git) is often required. Strong problem-solving skills, attention to detail, and effective teamwork are essential soft skills for this role. These abilities enable engineers to develop accurate, efficient simulations and collaborate effectively in multidisciplinary teams, ensuring successful project outcomes.

Job description

STR is hiring an Associate Software Engineer to join our multidisciplinary team of researchers and engineers developing cutting-edge technologies with significant and immediate impact on our national security. In this role, you will work at the intersection of computer systems and real-world physical systems, building the tools and models that emulate complex cyber-physical platforms to enable analysis, reverse engineering, and experimentation.

We believe every employee brings a unique set of skills, experiences, and perspectives that are essential to providing innovative solutions for our customers. You do not need to have experience with every technology listed to be successful in this role. Strong fundamentals, curiosity, and the ability to learn new tools and domains are highly valued.

What you will do:

  • Work as part of a small, focused team to architect, develop, implement, and test modular software applications and tools for emulating cyber-physical systems.
  • Extend and customize existing emulation frameworks (e.g., QEMU) in C/C++ and Python to support new targets, peripherals, and capabilities.
  • Rehost unknown or sparsely documented firmware by analyzing binaries, identifying hardware dependencies, and adapting these to run correctly in emulated environments.
  • Develop emulator tooling and virtual device models to support reverse engineering and analysis of embedded systems across diverse architectures (e.g., ARM, PPC).
  • Develop digital models using virtualization tools (e.g., QEMU) and network them together to create integrated, end-to-end system simulations that closely approximate real hardware behavior.
  • Ensure model quality and correctness through unit-level and system-level testing, and by validating behavior against first principles, measured data, documentation, and hardware/software artifacts.
  • Communicate technical foundations of models and algorithms through reports and briefings

Who you are:

  • This position requires an Active Secret security clearance with eligibility for Top Secret (TS) clearance, for which U.S. citizenship is needed by U.S. Government.
  • Proficiency in C/C++ for systems-level or embedded software development
  • Proficiency in Python for tool development, automation, and integration
  • Familiarity with emulation and virtualization tools (e.g., QEMU or similar frameworks)
  • Strong understanding of computer architecture, emulation principles, and software engineering best practices (e.g., modular design, testing, code review)
  • Experience using collaborative source code management (e.g., Git)

Education:

  • BS in Computer Engineering, Computers Science, Electrical Engineering or related field

Nice to have:

  • Active Top Secret (TS) Security Clearance
  • Familiarity with network architecture and protocols, and experience integrating networked simulations
  • Experience with low-level software modifications (e.g., implants, firmware changes, binary patch development)
  • Experience at the software/hardware interface, including device drivers or real-time/embedded operating systems
  • Experience with reverse engineering and firmware rehosting for embedded systems, including analysis of instruction set architectures (e.g., ARM, PPC) and use of tools such as Ghidra, IDA Pro, or Binary Ninja
  • Experience implementing component models (e.g., sensors, actuators, dynamics, environmental factors) in Python and/or C/C++, and integrate them into system-level simulations and software processing chains
  • Experience working with hardware components and interfaces
  • Masters or PhD in related field

Pay Information
Full-Time Salary Range: $92,000 - $128,000

The salary range listed is based on external market data. Offers are based on factors, such as but not limited to, the candidate's experience, education, training, key skills/critical skills, security clearances, and prevailing market and business conditions.
