* Partner with other software engineers to increase deployment confidence, operational visibility, and platform reliability.
* Implement and maintain monitoring, alerting, logging, and operational analytics to support proactive issue detection and response.
* Build and enhance tools that improve debugging, troubleshooting, and production support.
* Help define and maintain cloud infrastructure patterns, templates, and environment standards in partnership with team architects.
* Mentor team members and help cultivate a strong engineering culture centered on ownership, continuous improvement, and technical excellence.
* 5+ years of professional software engineering experience, with significant experience building and delivering modern web applications.
* Strong experience with JavaScript-based full-stack development, including technologies such as Node.js, Express, Vue, and related frameworks.
* Demonstrated expertise in software engineering fundamentals, application architecture, and sustainable development practices.
* Experience working in a modern CI/CD environment with automated build, test, and deployment workflows.
* Experience with cloud platforms, preferably Azure, with familiarity in AWS considered a plus.
* Experience improving or supporting application reliability through monitoring, alerting, observability, operational tooling, or cloud infrastructure practices.
* Working knowledge of database technologies such as SQL Server, SQLite, document, or key/value stores.
* Strong problem-solving ability and a demonstrated track record of turning product needs into practical technical solutions.
* Excellent interpersonal, collaboration, and communication skills.
* A self-driven mindset with the ability to take high-level goals and execute independently.
Preferred Qualifications
* Experience working on customer-facing digital products in a fast-moving, product-oriented environment.
