Rewarding experience. Meaningful Outcomes.

Making a difference in people's lives through design and implementation of leading network technologies. That's what motivates us.

A distinct culture

Embrace diversity. Celebrate inclusion. Champion ideas. From across the table to around the world, our path to innovation comes from our friendly environment and outstanding people. That's the Ciena network

A distinct way to work

Innovation. It’s what we do. And it’s how we work. Free thinking, free discussion, and collaboration are the norm. More satisfying outcomes—both personal and professional—are our endgame. That’s the Ciena difference.

Pursuing a Career

We are responsible

Our Corporate Social Responsibility practices and policies are designed to help Ciena operate as a supplier of choice, an employer of choice, and a neighbor of choice around the globe.

Our commitment to corporate social responsibility is incorporated into our business through the processes and procedures we follow in our operations, the ethical policies we enforce in our workplace, and the support we provide to the communities where we operate.

Community support and outreach

At the local level, we encourage our employees to get involved in their communities by supporting schools, food banks, and emergency relief programs and by participating in events such as blood drives, food collection drives, and charity races and golf tournaments that benefit local, national, and international organizations.

Community engagement

Ciena’s commitment to the communities where we live and work can be summed up with one simple statement: Ciena Cares. We care about our neighbors, our customers, our industry, and our current and future employees. Under the umbrella of Ciena Cares, our community support and involvement activities fall into three primary areas:

  • Donations to national and international philanthropic non-profit organizations
  • Support of STEM (Science, Technology, Engineering and Mathematics) education programs
  • Participation in local community support organizations and events selected by local employees


Ciena Cares supports a variety of national and international charities at the corporate level, such as The United Way and The Prince’s Trust. We also match employees’ charitable donations from $25 up to $500 (USD, or local equivalent) to eligible non-profit organizations, and make corporate-level donations in support of fundraising programs for assistance and disaster relief campaigns.

Support for STEM education

Ciena Cares provides in-kind donations and organizes team volunteer events for STEM (Science, Technology, Engineering and Mathematics) education with local schools from primary grades through college and university, as well as foundations and non-profit organizations focused on education.

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.
