About the role

In this role, you will work at the lowest levels of the software stack, enabling predictable execution across complex multicore processors and supporting safety‑critical certification activities.
This opportunity may be performed in a hybrid/onsite capacity in Endicott, NY.
This is where problem-solvers, innovators, and visionary thinkers come together to shape the future.

Develop and maintain low‑level embedded software using C, C++, and assembly, with a focus on processor‑level control and deterministic execution.
Design, implement, and analyze multicore synchronization strategies including cache management, interference mitigation, and timing‑aware resource coordination.
Perform complex analytical evaluations such as Worst‑Case Execution Time (WCET) assessments and DCCC (Deterministic Cache and Core Contention) analyses.
Integrate and validate interfaces with FPGA/ASIC components, ensuring reliable, timing‑critical embedded communication.
Participate in architecture discussions, design reviews, verification planning, and continuous improvement of real‑time multicore development processes.

U.S. citizenship is required.
Demonstrated expertise in low‑level embedded software development in C, C++, and assembly.
Hands‑on experience with multicore synchronization, S32 Processor family, cache behavior, interference channels, and deterministic execution strategies.
Familiarity with DO‑178C certification practices, especially Level A verification environments and associated test infrastructures.
Proven experience in avionics, safety‑critical, or other deterministic real‑time domains.
Experience with FPGA/ASIC interfaces and timing‑critical embedded communication protocols.
Proficiency with ARM DS IDE, DSTREAM, and Python for tooling, automation, and analysis.

Prior experience with multicore processor architectures in avionics, aerospace, defense, or other safety-critical embedded systems.
Hands-on experience with deterministic execution analysis, timing closure, interference analysis, or resource contention mitigation.
Familiarity with the S32 processor family or similar ARM-based multicore platforms.
Experience working closely with FPGA, ASIC, hardware, systems, or verification teams in an integrated engineering environment.
Experience participating in software architecture reviews, certification reviews, or technical customer discussions.
Active security clearance or ability to obtain a clearance.
