Meet the Team

Cisco's Webex Engineering Group is redefining the future of collaboration. We're building a world where people connect effortlessly to enjoy modern, uncompromised collaboration across every room, desk, pocket, and application.

Our technology powers industry-leading products such as Webex Meetings, Webex Calling, and Webex Contact Center. As a member of our team, your work will ensure every user gets a truly immersive experience across desktop and mobile devices, empowering the hybrid working patterns of the future.

Our engineering teams know the right things to do and are empowered to do them. This is a friendly, energetic environment with a fast pace of delivery, working closely with UX design and product management teams.

Your Impact

• Design, build, and technically lead end-user features used by millions of people worldwide across desktop and mobile applications.
• Develop high-quality, performant application software using modern C++, including shared components and capabilities integrated into native iOS and Android experiences.
• Own the breakdown of product requirements into clear technical designs and executable tasks, delivering high-quality, maintainable solutions within an existing framework.
• Make pragmatic design decisions across shared, cross-platform code and platform-specific implementations, taking account of performance, reliability, security, accessibility, battery life, and device constraints.
• Act as a technical point of reference for the team - reviewing designs and code, guiding implementation decisions, and raising the bar for engineering quality.
• Listen to the customer and elevate their experience. CSAT, NPS, app feedback, crash data, telemetry, and quality metrics are their voice - investigate issues, identify root causes, and drive meaningful improvements.
• Partner closely with engineers, product managers, and designers to deliver consistent, intuitive experiences across platforms, balancing speed, quality, and long-term sustainability.
• Improve engineering efficiency through automation, including development tooling, test automation, CI/CD workflows, diagnostics, and mobile build and release processes.
• Enable the team to focus on complex problems by using AI tools effectively and responsibly across the development lifecycle.
• Mentor and support other engineers, fostering a culture of learning, ownership, and continuous improvement.
• Bring your fun, curiosity, and personality to the team.

Minimum Qualification

• Education: Bachelor's degree in an analytical subject such as Computer Science, Electronic Engineering, or Software Engineering, or equivalent practical experience.
• Experience: 5+ years of professional software development experience or equivalent, with a strong track record of delivering production-quality software at scale.
• Programming: Strong proficiency in modern C++ or another relevant language, such as Swift, Kotlin, Java, C#, Rust, or Objective-C, along with the ability and willingness to work in and develop proficiency with modern C++.
• Application development: Experience developing customer-facing applications for at least one major platform, such as iOS, Android, Windows, macOS, Linux, or Web, and the ability to apply that expertise in a cross-platform environment.
