• Facilitate and model responsible adoption of agentic software engineering practices across teams, establishing patterns that improve developer velocity, testing rigor, documentation quality, and operational safety.

Minimum Qualifications

• Bachelor’s degree in Computer Science or equivalent practical experience.
• 6+ years experience building, testing, and operating complex backend or platform engineering systems in production.
• Expert-level proficiency in at least one major programming language (Python, TypeScript, Java, or equivalent) with practical knowledge of others.
• Demonstrated ability to design and operate highly available, scalable distributed systems using cloud infrastructure and Infrastructure as Code tools (Terraform preferred).
• Deep expertise in CI/CD automation, testing frameworks, and observability tooling (e.g., Datadog, Prometheus).
• Hands‑on experience managing and optimizing containerized environments (Kubernetes, Cloud Run).
• Proven record of operational excellence, including participation in on‑call rotations and debugging complex production issues across multiple services.
• Strong strategic communication skills, capable of clearly articulating technical proposals to both technical and non‑technical stakeholders.
• Hands‑on experience with AI‑assisted engineering workflows that maintain code quality, system reliability, security, and compliance requirements.

Preferred Qualifications

• Experience designing and managing internal developer platforms, tools, or frameworks used widely across multiple teams or departments.
• History of significantly influencing technical roadmaps, architectural standards, and engineering practices across teams.
• Proven ability to collaborate effectively with senior business leaders, translating technical strategy into measurable business value.
