Diagnose, troubleshoot, and resolve software defects or system integration issues, including support for deployed operational systems
Collaborate with customers and cross‑functional engineering teams to clarify requirements, support operations, and identify technical improvements
Produce and maintain technical documentation, participate in design/code reviews, and contribute to continuous improvement of engineering processes
Provide coaching and mentorship to junior engineers, supporting a culture of learning and growth
Travel up to 20%
Qualifications:
