• Foster a culture of collaboration, ownership, and trust by building strong relationships across teams, encouraging open communication, and influencing through empathy and credibility
• Mentor and support engineers across all levels, helping them grow in technical depth, architectural thinking, and leadership skills
• Continuously evaluate emerging technologies and industry trends, identifying opportunities to modernize our tech stack and improve development velocity
• Facilitate and lead architectural reviews, technical deep-dives, and collaborative design sessions to identify risks early, explore alternatives, and document key decisions
