Google is hiring SETs

Friday, March 12, 2010

Drop me a resume and a brief note if you're interested in joining Google as an SET. email: test.eng.hiring@gmail.com. Thanks -- Patrick Copeland
When we hire people we look for folks with a "testing DNA." These are people who are great computer scientists at their core, but also are very curious, love software, and are passionate about test engineering. People who have those characteristics tend to pursue challenges and continue to learn. Are you one of us? We have positions all over the US and the world.
What is a SET?At Google, Software Engineers in Test (SET) develop test frameworks and build robust, scalable, and effective tests. SETs spend a majority of their time coding in either C++, Java, or scripting in Python. A SET is a software engineer, a core developer, who has a passion for test engineering.
How is testing done differently at Google?

Literally within milliseconds of a code check-in, our build process will automatically select the appropriate tests to run based on dependency analysis, run those tests and report the results.
By reducing the window of opportunity for bad code to go unnoticed, overall debugging and bug isolation time is radically reduced. The net result is that the engineering teams no longer sink hours into debugging build problems and test failures.
Development teams write good tests because they care about the products, but also because they want more time to spend writing features and less on debugging.
Testing teams focus on higher abstractions, like identifying latencies, system or customer focused testing, and enabling the process with tools.
SETs avoid becoming codependents within this system and generally do not write unit tests or other activities that are best done by the developer.

More about SETs

Our SET’s spend time developing code to prevent bugs. Google has a strong cultural emphasis on developers improving quality (i.e. unit tests, code reviews, design reviews, root cause analysis). We want our engineers to spend their time innovating - not fixing bugs.
SETs enable products to launch faster. They have great influence over internal processes and how developers write code.
One of Google's less understood capabilities is our massive distributed computing environment. The testing groups exploit this infrastructure to do huge amounts of work very quickly and elegantly.
For someone who wants to learn and grow as an engineer, the uninhibited access to the entire code base is a unique opportunity.

Still Stuck in the 90s

Monday, March 01, 2010

Flashback. It's 1990. Chances are you do not own a cell phone. And if you do it weighs more than a full sized laptop does now. You certainly have no iPod. The music in your car comes from the one or two local radio stations that play songs you can tolerate and a glove box full of CDs and cassettes. Yes, I said cassettes...you know the ones next to those paper road maps. Music on the go? We carried our boom boxes on our shoulder back then.
If you are a news junkie, you get your fix from the newspaper or you wait until 6 ... or 11. Sports? Same. Oh and I hope you don't like soccer or hockey because you can't watch that stuff in this country more often than every four years. Go find a phone book if you want to call someone and complain.
I could go on, and on, and on, but you get the point. Oh wait, one more: how many of you had an email address in 1990? Be honest. And the people reading this blog are among the most likely to answer that affirmatively.
The world is different. The last 20 years has changed the human condition in ways that no other 20 year period can match. Imagine taking a 16 year old from 1990 and transplanting him or her to a 2010 high school. Culture shock indeed. Imagine transporting a soccer mom, a politician, a university professor... Pick just about any profession and the contrast would be so stark that those 1990 skills would be a debilitating liability.
Except one: that of a software tester. A circa 1990 tester would come from a mainframe/terminal world. Or if they were on the real cutting edge, a locally networked PC. They'd fit into the data center/slim client world with nary a hiccup. They'd know all about testing techniques because input partitioning, boundary cases, load and stress, etc, are still what we do today. Scripting? Yep, he'd be good there too. Syntax may have changed a bit, but that wouldn't take our time traveler long to pick up. That GEICO caveman may look funny at the disco, but he has the goods to get the job done.
Don't get me wrong, software testing has been full of innovation. We've minted patents and PhD theses. We built tools and automated the crud out of certain types of interfaces. But those interfaces change and that automation, we find to our distress, is rarely reuseable. How much real innovation have we had in this discipline that has actually stood the test of time? I argue that we've thrown most of it away. A disposable two decades. It was too tied to the application, the domain, the technology. Each project we start out basically anew, reinventing the testing wheel over and over. Each year's innovation looks much the same as the year before. 1990 quickly turns into 2010 and we remain stuck in the same old rut.
The challenge for the next twenty years will be to make a 2010 tester feel like a complete noob when transported to 2030. Indeed, I think this may be accomplished in far less than 20 years if we all work together. Imagine, for example, testing infrastructure built into the platform. Not enough for you? Imagine writing a single simple script that exercises your app, the browser and the OS at the same time and using the same language. Not enough for you? Imagine building an app and having it automatically download all applicable test suites and execute them on itself. Anyway, what are you working on?
Interested? Progress reports will be given at the following locations this year:
Swiss Testing Day, Zurich, March 17 2010
STAR East, Orlando, May 2010
GTAC, TBD, Fall 2010
Here's to an interesting future.
