structures, algorithms, and systems design. Exceptional
communication (written and verbal) and documentation skills, with a
proven ability to articulate complex architectural decisions to
diverse audiences. A highly collaborative, team-oriented, and
positive attitude, with a knack for mentoring and elevating the
entire team. Preferred Qualifications 8 years of professional
experience in software development. Professional experience with
C++ and Python. Experience designing scalable and modular
solutions, including multi-threaded applications and stateless
services. Experience developing with networking protocols (e.g.,
TCP/IP, UDP) and building distributed systems. Familiarity with
CI/CD, test automation, simulation, or hardware-in-the-loop (HITL)
testing. Experience with modern monitoring, data analysis, and
visualization tools. Experience with Linux-based development
environments. A creative and analytical approach to solving
ambiguous and complex technical problems. Proven ability to thrive
and provide technical leadership in a fast-paced, dynamic
environment. A passion for tackling complex problems and taking
