Linux Systems Engineer - Security
New York, New York, United States
The mission of Two Sigma is to find value in the world's data. At our core we are a technology business. We use vast data sets from over a thousand diverse sources, advanced machine learning techniques, and scientific approaches to find critical connections that help drive the world's economy, safeguard the retirement savings of millions of people, and fund groundbreaking research.
At Two Sigma we fully embrace our "Nice Geeks" culture. Our facilities are designed to encourage people to come together and share ideas. Our personnel are rewarded for cross group collaboration and driving innovation. We also embrace fun and encourage play because we know giving our brains activity outside of our core jobs helps us be more creative and gain new insights that are relevant to our daily tasks.
Because we are looking for radical, novel, unique, inspiring, and innovative solutions, we place a high premium on diversity. We need people who see the world from angles we don't, so we can ensure that our solutions are the best possible, for the greatest number of people possible. We also know that embracing diversity of all kinds leads to inspiration, which leads to innovation, which allows us to change the world. If you are passionate, and interested in joining us on this adventure, we would love to meet you.
The Two Sigma Security team is focused on pushing the boundaries of what is possible when we reevaluate traditional assumptions and embrace modern technology. Whether we are unlocking the potential of quantitative analysis, pushing the limits of zero trust, driving cloud infrastructure to new heights, or developing our own solutions to common authentication and authorization challenges, we embody a culture of proactive and transparent innovation.
