We are looking for a motivated Application Security Engineer who is looking to help build the maturity of our Application Security Team while growing their own security skill set. Our team prioritizes the full lifecycle of security triage: identifying vulnerabilities, reproducing exploits, meticulous code analysis, and crafting production-ready fixes. We are looking for an engineer with good attention to detail, the ability to learn quickly and pick up new skills independently, and a get-things-done attitude with eagerness to build something awesome! What will you do? Work with a nimble passionate security team, collaborating with development and product. Conduct vulnerability triage: handle internal and external vulnerability reports, and more importantly: go beyond investigating and write fixes yourself. Review code and help make decisions about secure coding decisions. 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. Use your detective work to get to the AH-HA! moment when you find and replicate the root cause of an issue and figure out how to fix it. 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. We work hard but we believe in maintaining a sustainable work/life balance. Really. Can I work remotely? Yes. We operate on PST and candidates in any time zone are welcome to apply. We ask employees to travel to our San Jose, CA office up to three times per year plus one company-wide offsite to collaborate in person and strengthen working relationships.
