Employee Testimonials:

1)  Aaron Ackerman: "There is a lot to learn, and I am still learning new things every day. And, my coworkers are amazing. Ciena has challenged me, but it is equally rewarding. And I see myself staying with Ciena for a very long time"

Network providers worldwide are adopting Software-Defined Networking (SDN) and virtualized services. They’re embracing agile development and operational processes. They’re doing what it takes to avoid disruption from more nimble competitors—and that includes opening up, in a way they never have before, to open-source.

Open-source software is driving much of the technology innovation network providers need to achieve their overall digital transformation. It harnesses the power of a community—and the collaboration that happens within it—to break through many of the traditional constraints associated with development. With open-source, technology improvements happen faster—which is why we’ve been using open-source innovations to create value for our customers for years.

Openness and collaboration are core to who we are at Ciena, and they’re key pieces of our Adaptive Network vision. We actively contribute to numerous open-source initiatives and projects, and incorporate multiple open-source components into our Blue Planet Intelligent Automation Platform. Blue Planet’s microservices-based architecture enables the platform to integrate best-in-class open-source software elements with our own innovations to provide a more flexible and extensible solution to meet our customers’ evolving requirements.

 Gender Diversity at Ciena

 As part of our commitment to Ciena’s Corporate Social Responsibility we want to foster an inclusive environment that values and respects all individual’s strengths, perspectives, ideas, and ability to meet the needs of our customers globally. Women@Ciena is the overarching initiative that encourages gender diversity. It does this by encouraging women to take the steps necessary to make the most of their careers; from onboarding new talent, coaching and mentoring to career planning, development and progression, as well as helping women reach the executive level.

Mission statement for Women@Ciena 

To establish a Ciena culture that cultivates, inspires, and rewards the contribution of every individual no matter what sex, race, religion or otherwise. Through active awareness, we are creating an environment that attracts, develops, and retains more women in our workforce. Ultimately, our goal is to create an understanding about the value of each individual, to break down barriers that exist, and empower the voice and talents of women in our workforce.

Global Women’s Council

As part of Women@Ciena we have a Global Women’s Council which is comprised of women and men from across the organization – all levels, regions and disciplines – to ensure a genuine cross-section of talent and insights. The council’s aim is to grow the company’s diversity program globally, with local action in each of the regions in which we operate. It involves the creation of smaller, regional groups to meet once a quarter as a ‘diversity team’ to share activities and develop new best practices as a grassroots program. The Global Women’s Council leaders initiate a local projects or initiatives every quarter as well as connect, communicate and participate with the other regional councils as a wider, global team.  

Women@Ciena Communications and Research 

Hosted on Ciena’s Intranet are resources for everyone to learn more about the aims of Women@Ciena and read news updates about gender diversity, recent successes and opportunities within the organization. Ciena also recently completed a Career Navigation Survey in partnership with YSC to gain a deep understanding of the drivers and barriers to success in Ciena for women (and men) which will provide relevant, practical, robust and systematic recommendations to address the successes, opportunities and risks to improve our gender balance.

    Best flexible hours as well as management for improvement and promotions.


    People are so great so to get promoted amongst the best is definitely a serious challenge but the quality of the management and colleagues is such that you still want to stick around...

    Advice to Management

    Have more senior management having periodic jobs for opportunities to grow further.
