Work hard. Have fun. Make history.

We are seeking an Embedded Software Development Engineer to design, implement, and maintain secure firmware solutions for our next-generation devices. In this role, you will be responsible for developing security protocols for device authentication and content protection, implementing cryptographic algorithms and security features in resource-constrained environments, and performing security threat modeling and risk assessments.

You will work closely with customers, system architects, program managers, and hardware engineers to integrate your security firmware into our cutting-edge products like Fire tablets, Fire TV, and Amazon Echo.

To be successful in this role, you will need a Bachelors degree in Computer Science, Software Engineering, or a related field, along with 5+ years of embedded software development experience. Strong proficiency in C/C++, understanding of secure boot processes and chain of trust, and experience with cryptographic implementations are essential.

Key job responsibilities
- Design and implement secure firmware solutions for device security, including developing authentication and content protection protocols
- Implement cryptographic algorithms and security features tailored for resource-constrained embedded environments
- Debug and maintain the security firmware stack to ensure compliance with security standards
- Perform security threat modeling and risk assessments to identify and mitigate vulnerabilities
- Review code for security vulnerabilities and adherence to security best practices
- Demonstrate strong proficiency in C/C++ programming and have a deep understanding of secure boot processes and the chain of trust
