Full Stack React Engineer

DescriptionActiveState enables DevOps, InfoSec, and Development teams to improve their security posture while simultaneously increasing productivity and innovation to deliver secure applications faster. We are the only solution in the market today that offers vulnerability-free open source language packages and containers and Intelligent Remediation, which identifies which vulnerabilities to prioritize, assesses the impact of updates causing breaking changes, prioritizes what to fix first, securely builds open source packages from source, and facilitates the build and deploy process to get fixes into production quickly and easily. All from the trusted partner that pioneered and continues to lead enterprise adoption and use of open source software. This position is open to full-time telecommuters anywhere in Canada or continental US. As a Full-Stack React Developer, you will be responsible for the end-to-end development of our core applications, from building highly responsive user interfaces with React to designing and implementing scalable backend services. You will be instrumental in bridging the gap between front-end design and back-end logic, ensuring seamless and secure data flow across the entire application. The ideal candidate has deep expertise in both modern JavaScript/React and modern backend development (in languages like Node.js, Python, or Go), and a commitment to ownership across the whole stack. You're focused on our customers—Developers and DevOps Engineers. You understand that your role is to help solve their problems. You're passionate about open source and want to learn more about the communities that build the software we all rely on. You're a true problem-solver, capable of tackling challenges across the entire technology stack. You're a great communicator. You can explain technical topics clearly and concisely to help others understand front-end architecture, API design, and database concerns. You have excellent judgment. You can prioritize complex full-stack tasks and understand which problems need immediate attention and which can wait. You're a collaborator. You work well with others across different teams like Research, Product, and Engineering. You're enthusiastic about our mission and want to help our platform become a global success.
