DEFEND PERISCOPE AND THE DATA OF OUR CUSTOMERS

Customers trust us with their most important data. They use Periscope to query everything from revenue metrics to the personally identifiable information of their users. You will lead the effort to constantly improve the security of Periscope's architecture, production systems, and corporate infrastructure.

You will own the overall security policies and implementation at Periscope. You'll be expected to design and deploy systems that are both highly secure and highly functional. Enabling everyone at Periscope to keep moving fast while continuously increasing the strength of our security may be your greatest challenge.

ABOUT PERISCOPE DATA:
We're a kind, curious, tight-knit bunch. We eat together, toast our shared accomplishments together, and often spend holidays and ski trips together.
We are on-boarding rapidly! The team grew from 20 to 69 in 2016, and will grow to 140 and beyond in 2017.
We believe strongly in a data-driven approach to all that we do. We're constantly measuring and optimizing everything about the business.
We have close relationships with our customers. We see customers several times a month, and email with them several times a week.
Recent Engineering Projects:
Speeding up metrics calculations by over 10,000X by implementing them as parallel bitwise operations on bitsets.
Improving chart render speed by over 100X by reimplementing on top of Canvas instead of SVG.
Auto-ETLing entire customer databases into our data cache while targeting < 1hr freshness on all customer data.
Implementing cross-database query translation and cross-database joins.
Our Interview Process:
We want to know what it's like to work together; there are never any riddles or whiteboards.
First you'll see Periscope and how customers use it. Later we'll code together online, or review your solution to an offline code challenge. And when you come on site to meet the team, you'll spend a couple hours pair programming in the Periscope codebase.
Periscope's most important feature is our phenomenal development speed. We deploy to production an average of 9.7 times per day. Much of this is cultural, and much of it is investing in anything that will reduce drag on the team, like fully automated testing, one-click test-and-deploys, and great whiskey. (Wait, what?)

We plan to double our team in the next six months. If you learn quickly and have that get-shit-done attitude, we'd love to talk to you!
