Job Description:
Job Description Job Description JOB DESCRIPTION: The Software
Integration & Operations (SIO) group turns frontier autonomy into
mission-ready aircraft. We own the commit-to-flight
pipeline—deterministic simulation at cluster scale, HIL/VIL
integration, CI/CD, automated testing, and release engineering. Our
goal is simple: make AI fly—safely, repeatably, and fast. As a
Staff Simulation Engineer, you will be dedicated to Shield AI’s
next-generation aircraft program, adopting our existing
infrastructure to advance new capabilities. You’ll design, build,
and scale C++-based simulation tools that test and validate the
full aircraft software stack—from autonomy to avionics—before it
ever flies. Your simulation infrastructure will enable developers
to test faster, system engineers to evaluate performance earlier,
and release engineers to ship with confidence. WHAT YOU'LL DO:
Build and scale simulation frameworks for integrated testing of
autonomy, GNC, and embedded systems in C++. Design deterministic,
high-performance simulation tools capable of faster-than-real-time
execution for development, testing, and release. Integrate core
physics, dynamics, and system models (aerodynamics, propulsion,
controls) into a unified simulation environment. Collaborate across
autonomy, embedded, GNC, and test engineering to ensure the
simulation mirrors real aircraft behavior and mission scenarios.
Develop infrastructure for CI integration, parallel simulation
execution, and automated regression testing. Profile, optimize, and
validate C++ codebases for performance, determinism, and fidelity.
Contribute to architecture decisions that define the next
generation of aircraft simulation tools within Shield AI. Mentor
engineers and guide best practices in C++, simulation architecture,
and performance engineering. REQUIRED QUALIFICATIONS: BS or MS in
Computer Science, Aerospace, Robotics, or related field. 8 years of
experience in software development, with emphasis on modern C++
(C++17 or later) and performance optimization. Proven experience
developing or integrating simulation systems for robotics,
aerospace, or autonomous systems. Strong grasp of real-time and
deterministic software design, including multi-threading,
synchronization, and memory management. Understanding of rigid-body
dynamics, kinematics, and basic flight mechanics. Familiarity with
DevOps-integrated simulation workflows, including CI/CD and
containerized environments. Ability to debug complex build and
runtime environments (CMake, dependency management, logging,
profiling tools). Strong collaboration and communication skills
across software, hardware, and systems disciplines. PREFERRED
QUALIFICATIONS: Experience with distributed or cloud-based
simulation (e.g., cluster orchestration, Kubernetes). Working
knowledge of Python for data analysis, test automation, or
simulation orchestration. Familiarity with sensor and actuator
modeling, and integrating avionics or autonomy software within
simulation. LI-SM1 We may use artificial intelligence (AI) tools to
support parts of the hiring process, such as reviewing
applications, analyzing resumes, or assessing responses. These
tools assist our recruitment team but do not replace human
judgment. Final hiring decisions are ultimately made by humans. If
