We’re looking for talented, experienced professional hackers to help us secure some of the world’s most complex software and sophisticated technologies. You’ll be working alongside our US and internationally-based teams supporting clients across multiple industries.

Responsibilities

You’re a penetration tester with experience assessing the security of electronic devices as well as software. You've used Ghidra or similar tooling to look for vulnerabilities in device firmware and know how to trace circuits to figure out which unpopulated pads are a JTAG interface or UART. Maybe you've even found a way to bypass a device's security controls using fault injection. You have a passion for hacking and information security.

With Bishop Fox, your responsibilities would include testing web applications, hacking networks, and reversing software. As a consultant, you’ll work on a variety of projects which include short-term engagements and extended program work with well-established clients. You'll solve challenging technical problems and build creative solutions. As a trusted advisor, you’ll provide your expert opinion to help our clients navigate difficult business decisions.

• Experience with OT network, industrial control systems (ICS), and SCADA security
• Familiarity with protocols like MQTT, CANbus, modbus, BACnet, etc.
• Understanding of hardware security on multiple platforms such as ARM, MIPS, etc.
• Experience with common hardware attacks such as dumping memory, attacking bootloaders, manipulating UART/JTAG/I2C/SPI interfaces
• Experience with pen testing automobiles/vehicles is a plus
• Vulnerability assessments including manual testing to further evaluate the security of applications
• Penetration testing and code review (including DAST and SAST; experience with low level languages, C/C++)
• Understanding security fundamentals and common vulnerabilities (e.g., OWASP Top Ten) in addition to more modern web app and enterprise app vulnerabilities

• Superior communication skills (i.e., written and verbal) - including the ability to work as a mentor on engagements
