What they’re looking for
- Proven experience in backend development, with a track record of delivering high-quality and performant projects.
- Background in cybersecurity, such as penetration testing, vulnerability assessment, or security code reviews.
- Demonstrated success in identifying and resolving software bugs and system bottlenecks.
- Experience with codebase refactoring and implementing complex features in large-scale applications.
- Strong understanding of algorithms, data structures, and foundational computer science concepts.
