You will lead the design of large‑scale distributed systems and drive cross‑team initiatives, translating abstract, long‑horizon goals into executable engineering plans that ensure high‑impact delivery across the organization.

• Lead the architecture, design, and evolution of core product microservices, ensuring they are secure, scalable, decoupled, and highly available.
• Design and deliver large‑scale, resilient distributed systems that support mission‑critical product features with strong performance and reliability guarantees.
• Drive cross‑organizational technical strategy to improve the agility, modularity, and operational excellence of the microservices ecosystem.
• Identify, define, and drive solutions for complex, ambiguous product and domain challenges that span multiple services and business units.
• Establish and champion best practices for domain‑driven design, strict API contract management, and observability.
• Accelerate product velocity and feature delivery through automation, standardization, and repeatable microservice design patterns.
• Improve end‑to‑end observability, reliability, and automated recovery for platform services, including proactive detection, self‑healing, and robust incident response.
• Advocate for the team by securing alignment on technical debt reduction, architectural modernizations, and adoption of cutting‑edge development tools.
• Champion the integration of AI‑assisted engineering tools and modern coding techniques, empowering the team to write higher‑quality code faster and safer.
• Provide technical leadership and mentorship to senior and staff engineers, raising the overall technical bar and fostering a culture of continuous learning and engineering excellence.
• Lead cloud infrastructure efficiency and cost optimization initiatives, particularly across large‑scale AWS & GCP deployments, ensuring architectural decisions balance high performance with financial scalability.

• Bachelor’s or Master’s degree in Computer Science, Engineering, or equivalent practical experience.
• 12+ years of software engineering experience, with a proven track record of designing, building, and maintaining large‑scale distributed systems and production‑grade microservice architectures.
• 12+ years of hands‑on experience with object‑oriented or functional programming languages, specifically Java or Scala.
• Solid experience delivering and scaling large distributed production services to a global enterprise customer base.
• 5+ years of experience building, operating, and driving cost‑optimization for products within large‑scale cloud environments, with deep expertise in AWS and/or GCP (including S3, Lambda, EC2).
• 5+ years of hands‑on experience with containerization and orchestration technologies, specifically Docker and Kubernetes.
• Hands‑on AI integration: proven ability to integrate AI capabilities directly into scalable software solutions while adhering to Responsible AI practices.
• Proficiency with AI‑assisted development tools (e.g., Cursor, Claude Code, Git Hub Copilot) and ability to review and validate AI‑generated code.
• Expert‑level programming proficiency in Java, Scala, and/or Go, with deep understanding of advanced design patterns and clean code practices.
• Deep experience with modern CI/CD pipelines, advanced IDE integrations, and robust automated end‑to‑end testing strategies.
• Experience managing and scaling cloud footprints across AWS and GCP, with a track record of cost‑aware architectural patterns.
• Strong track record of partnering closely with Product Management and cross‑functional stakeholders to define, refine, and break down complex technical and product requirements.
• Excellent verbal and written communication skills, with demonstrated ability to articulate complex technical concepts and influence business partners.
• Experience delivering high‑impact initiatives within fast‑paced, matrixed, and agile enterprise environments.
