Seattle, WA - ExtraHop Networks - Software Engineers, Testing Engineers, Support Engineers, Sales Engineers, and more.
ExtraHop is a ~4 year old, fast growing startup building network appliances for application analysis.  Think HTTP/DB/memcache/NAS/etc processing times for all the servers in a datacenter, all by passively watching the network.
I'm a software engineer at ExtraHop and here's why I love my job:
1. The team is amazing and everyone makes a difference. The two founders, Jesse and Raja, designed and built BigIP v9 when they were at F5 Networks before founding ExtraHop, and are still very much involved in engineering. It's a great working environment and we have a lot of fun.
2. Hard problems at all levels.  We parse a bunch of different protocols at 10Gbps by writing high-performance multithreaded C and our own linux kernel drivers.  Our datastore handles 200,000 inserts a second with 10MB/s of data.  Our UI has a ton of charts and tables, with data going through django and tornado.  We use python, C, javascript, flex (slowly moving to a new UI with html5 + javascript), and a modified yacc+bison for some of our protocol parsers. You can hack anything from C to the front-end design and anywhere in between.
3. Our customers love it.  It's awesome to see problems diagnosed and solved with our box.
