Anyone want a project/program manager?

Kash (YC S14) - San Francisco, CA or Kitchener/Waterloo, Canada - http://withkash.com

Kash is hiring engineers to kill the evil credit card giants. They have a stranglehold on in-person paperless payment. We want to provide an alternative.

Did you know that the credit card industry often makes way more money from retail stores than the store owners themselves? One of our store owners makes $60K a year while credit cards charged the store $72K.

At Kash, we're on a mission to end the credit card monopoly and replace it with an option that helps retailers and that consumers love.

Right now our system works similar to the Starbucks app, but we're always evaluating technology that can make the experience better.

Come chat with us if you think this is a worthy cause. After all, you don't take down giants by doing things half-heartedly.

For more details and to apply, please visit https://jobs.lever.co/kash. Please mention that you saw us on HN.

Just want to get in touch? Please email me at danny@withkash.com

Matasano Security - Chicago. New York City. Sunnyvale. Job Title: Application Security Consultant

Have you ever seen the 1992 film Sneakers? Near the start, we see Martin Bishop (Robert Redford) close out a bank account, and take the proceeds to the managers. He pretty tersely says something like:

"Gentlemen, your communication lines are vulnerable. Fire exits need to be monitored. Your rent-a-cops are a tad undertrained. Outside of that, everything seems to be fine. You'll get our full report in a few days. But first, who's got my check?""

Cut to a bank secretary, writing Martin a check.

"So, people hire you to break into their places... ...to make sure no one can break into their places?"

Whenever I'm asked to explain what we do at Matasano, this scene comes to mind. Our work is the digital equivalent; breaking applications so they can be made stronger and more resilient to attack, inoculating the world's software like a binary flu shot.

Modern applications are a lot like the bank in the movie. Authentication protects the front door, much like the bank's cameras and guards. Encryption often protects sensitive data, similar to how steel lined walls protect a bank vault. Communication protocols convey information in and out, like armored cars ferrying cash to and fro. Finding the application's 'communication lines', 'fire exits', and 'rent-a-cops' is our goal. As Application Security Consultants we seek the overlooked, the neglected, the unexpected flaws in an application's code. Like Martin, we show how these weaknesses can lead to overall failure of the application, and we do this so it can be improved.

Later in the movie, Cosmo (Ben Kingsley), a villainous ex-con says: "The world isn't run by weapons anymore, or energy, or money. It's run by little ones and zeroes, little bits of data. It's all just electrons." In 1992, that might've been hyperbolic but it's becoming more true every day.

If being part of ensuring the systems we all rely on continue to function safely and reliably, we should talk. If working with smart people on the cutting edge of technology excites you, we should talk. If diving deeply into a wide variety of technologies and facing new challenges daily appeals to you, we should talk. If tearing apart application code and making it do things that its creators didn't intend is fun for you, we should talk.

You can get a taste for the sorts of things we do at www.microcorruption.com and www.cryptopals.com.
