We manage the performance test infrastructure and our in-house load generation tool, enabling teams to run performance tests, benchmark services, and proactively identify potential performance bottlenecks. Partnering with SRE, we stress-test infrastructure, providing actionable recommendations to improve reliability and uptime.
Our team thrives on fostering a culture of continuous improvement, and we are passionate about helping each other grow. Join us and be part of a team that thrives on collaboration and a passion for innovation!
Your Impact
As a Tech Lead on our team, you will be responsible for maintaining and extending our existing in-house load generation tool, identifying performance bottlenecks, and consulting with engineering teams on optimization efforts. These optimizations could involve the data layer, infrastructure, or other areas where performance can be improved. You will also play a key role in reviewing service architecture and recommending performance testing strategies to ensure we can effectively benchmark and load test services before they are released to our customers. Additionally, as a leader, you’ll help drive innovation and expand our practices to ensure reliability, including exploring new approaches like chaos testing. Your leadership will be crucial in making our services more scalable, and resilient.
Key Responsibilities:
#WeAreCisco where every individual brings their unique skills and perspectives together to pursue our purpose of powering an inclusive future for all.
Our passion is connection—we celebrate our employees’ diverse set of backgrounds and focus on unlocking potential. Cisconians often experience one company, many careers where learning and development are encouraged and supported at every stage. Our technology, tools, and culture pioneered hybrid work trends, allowing all to not only give their best, but be their best.
We understand our outstanding opportunity to bring communities together and at the heart of that is our people. One-third of Cisconians collaborate in our 30 employee resource organizations, called Inclusive Communities, to connect, foster belonging, learn to be informed allies, and make a difference. Dedicated paid time off to volunteer—80 hours each year—allows us to give back to causes we are passionate about, and nearly 86% do!
Our purpose, driven by our people, is what makes us the worldwide leader in technology that powers the internet. Helping our customers reimagine their applications, secure their enterprise, transform their infrastructure, and meet their sustainability goals is what we do best. We ensure that every step we take is a step towards a more inclusive future for all. Take your next step and be you, with us!
