Connexity - Camarillo/Los Angeles, CA
We're building a sophisticated advertising platform to help brands and retailers sell efficiently through loads of shopping intent data.
1) We need a Rails dev to own our campaign management interface.  While we have a growing set of systems doing automated optimization and altering, you'll help humans effectively manage hundreds of campaigns for well-known brands and retailers.  We serve 50+ million ads every day and process 3.5 billion transactions, and you'll be right in the thick of it.  You'll work directly with Postgres, Redis, HBase and Hadoop.  You'll also likely play a key role in developing a new API for several key partners.
2) We need someone with fierce tenacity to run QA and technical ad operations.  When an account manager sees that we recorded no clicks for a certain campaign in Firefox browsers, you'll get to hunt down the resolution.  You'd bring a meticulous eye for detail to bear with browser and Javascript chops.  Done well, you'll be a daily hero.  (As it turns out, the folks writing "system code" perform best when they can stay in the zone, head down as much as possible.)  Count on becoming well acquainted with Hive.
3) Finally, we're looking for a strong DevOps team member.  You know networking and Linux very well.  You'll help improve our Hadoop clusters.  You'll tune monitoring and alerting thresholds.  Most importantly, you'll eagerly seek to expand your usefulness as you work with the rest of the dev team.  We're not driven by dogma, and you'll find yourself in good company if your sole priority is fixing the problem at hand.
I'm one of the lead devs, and you can reach me at REDACTED_EMAIL.  I'm happy to speak informally about our situation, and can hook you up with the HR folk at the appropriate time.
