About the role

Lead architecting and building next-generation real-time communication technologies (voice, video, and AI-powered experiences) across Windows, iOS, Android, web, and virtual desktop environments; provide technical leadership, define architectures, and drive AI-assisted engineering initiatives.

Responsibilities

  • Lead the architecture, design, development, and delivery of complex software systems and client platform capabilities supporting real-time communications across mobile, desktop, web, and virtual desktop environments.
  • Design and build secure, reliable, diagnosable, maintainable, and reusable native client libraries and SDK capabilities across Windows, iOS, and Android ecosystems.
  • Define and drive technical solutions across multiple components and teams, identifying dependencies, evaluating architectural tradeoffs, and building alignment with engineering and partner organizations.
  • Develop and improve AI-assisted and agentic engineering capabilities that support software development activities such as investigation, testing, validation, code review, reliability, and incident response.
  • Improve engineering infrastructure, documentation, build and test automation, validation mechanisms, and development workflows to enable reliable and efficient AI-assisted engineering.
  • Develop reusable engineering patterns, tools, and capabilities that can be adopted across teams while balancing common platform requirements with domain-specific needs.
  • Establish engineering practices and validation mechanisms to evaluate the quality, reliability, security, and effectiveness of AI-assisted or automated engineering workflows, including appropriate human review.
  • Collaborate with engineers, product managers, and partner teams to understand requirements, document technical designs, implement features, develop testing strategies, manage feature rollouts, and establish monitoring and telemetry.
  • Use telemetry, diagnostics, experimentation, and production data to understand system behavior, evaluate engineering tradeoffs, and identify opportunities to improve performance, reliability, security, and customer experiences.
  • Participate in design and code reviews and provide technical leadership and mentoring to engineers across the organization.
  • Participate in on-call and site reliability activities, including investigating and responding to live-site issues and identifying engineering improvements that increase reliability and supportability.
  • Collaborate across Microsoft with engineering, security, privacy, compliance, and product teams to deliver solutions that meet technical and business requirements.
  • Make data-informed technical tradeoffs across competing requirements, balancing short-term needs with longer-term architecture, maintainability, and engineering quality.
  • Embody our culture and values.

Qualifications

  • Bachelor's Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.
