J Conlin
Staff Engineer at Mozilla
San Jose, California, United States
Summary
🤩
RockstarJ Conlin is a Staff Engineer in San Jose with 14 years of hands-on experience building and operating back-end systems, tooling, and security-sensitive services. He prefers being a versatile "swiss army knife," moving fluidly between customer support, architecture, and low-level implementation across languages like Rust, Go, Python, PHP, and JS. At Mozilla he contributes to core pieces of application services and sync storage, and his open-source work includes cryptography and performance-focused improvements (e.g., adding DynamoDB caching to a high-profile Heartbleed checker and extending actix-web testing). Comfortable with CI/CD, containerized builds, and security auditing, he brings pragmatic engineering judgment to both prototype features and production hardening. Expect a curious problem-solver who uses technology in unexpected ways to simplify real-world workflows.
