Impermium (<a href="https://www.impermium.com" >) - Redwood City, CA
Impermium is a leader in web security, protecting against account compromise, counterfeit registrations, and malicious activity. We generate a real-time risk profile for user activity, enabling sites to take immediate, proactive action against abuse.
On the engineering side, we are primarily a Python shop, although we use the Hadoop ecosystem extensively so there is some Java and we're playing around with Scala. We are a small company of about 15 who are easy-going and super fun to be around.
We're hiring for a couple positions right now, including:
* Senior Data Mining Research Engineer - We need someone who can go from a conversation about stochastic gradient boosting distributed decision trees to a prototype and from a prototype to a fast, scalable, and robust production model.
* Senior Software Engineer - You are an experienced, knowledgable developer who has a breadth of experience and can jump in and ship code on the first day. Experience with big data is a plus.
* UX Design Lead - You'll be leading our creative design and our user interaction from conception into production. We're particularly looking for designers who have a vision for big data visualizations.
