- Lead critical technical escalations and complex system incidents, driving effective recovery and long-term reliability improvements.
- Shape AI adoption strategies across engineering teams, including AI-assisted development, automated incident response, and production safeguards.
- Partner with engineering leaders, Product, and business stakeholders to translate ambiguous business problems into technical strategies that support organizational goals.
- Establish engineering best practices, mentor technical leads, and raise engineering standards through influence and collaboration.

Who You Are:

- 10 to 12+ years of experience building, architecting, and scaling complex production software systems.
- Deep expertise in at least one mainstream programming language (JavaScript/TypeScript, Python, Java, Go, Ruby, PHP, C#, etc.), with the ability to work across different technology stacks.
- Excellent computer science fundamentals, problem-solving skills, and architectural design capabilities.
- Proven experience owning complex systems and driving technical architecture and initiatives across multiple engineering teams.
- Strong understanding of distributed systems, system scalability, security, performance, and architectural trade-offs.
- Demonstrated ability to lead high-impact engineering projects, manage critical technical escalations, and make sound decisions under pressure.
- Strong strategic thinking and communication skills, with the ability to influence engineering direction and align technical decisions with business objectives.
- Proven ability to mentor senior engineers and technical leads while building ownership and technical capabilities across teams.
- Experience driving engineering improvements, technical standards, and organizational adoption of new technologies.
- Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience.

Nice to Have:
