Red Balloon Security | Security Researchers, Software Engineers | NYC, Northern Virginia | ONSITE, HYBRID | Full-time, Interns (paid) | US Citizenship Required | https://redballoonsecurity.com We are a team of expert researchers and engineers focused on securing embedded devices. We work with partners across critical industries, and on government-funded research programs (think DARPA). "Full-stack" for us doesn't just stop at back end code; it means being comfortable with operating systems, firmware, and signals going over the wire. You'll succeed here if you are a quick learner who loves working independently on tough, technical problems nobody has ever solved before. Day-to-day tasks might include: * Tearing apart a device in our lab, reverse engineering its firmware, and finding security vulnerabilities * Developing an automated, robotic platform for hardware reverse engineering (custom hardware, vision models, user interfaces, etc.) * Hooking and patching RTOS kernel functions to execute defensive device integrity validation code, without violating real-time requirements * Building scalable servers for processing millions of device telemetry messages across thousands of concurrent connections * Maintaining open-source reverse engineering tools (like OFRAK https://ofrak.com) and cooking up fun demos for hacker conferences (like this web game we built for DEF CON in 2023 https://ofrak.com/tetris/) Our main office is in Manhattan, but we are building out a new office in Northern Virginia. US citizenship required. Bonus points if you have an active security clearance, or are willing to get one. https://www.linkedin.com/jobs/view/4367488549
