Review new product features to ensure they are designed with security in mind Collaborate with other developers and teams for long term security success. Code solutions for preventative measures and generating alerts.

You will care and be involved in our product, mission, and success - way beyond checking off tasks. What will you NOT do? You will NOT worry about "runway", "cash left", or "how much time we have until the next round". We have the startup DNA but we're fully backed and funded, all the way to success. You will NOT be confined to your "job". You will get involved in product, marketing, business strategy, and almost everything we do. You will NOT be bogged down by office politics, ego, or bad attitude. Only positive, pleasure-to-work-with people are allowed here! You will NOT get yourself burned out.
