Senior Full Stack Engineer (Java) — Cebu, Philippines

8x8 is looking for a talented Senior Full Stack Engineer with deep, recent Java expertise to join our growing team in Cebu. You'll play a pivotal role in building a new SaaS product from the ground up, collaborating with colleagues across Singapore, Europe, and North America in a fast-moving, agile environment.

What You'll Do

• Design and build robust, scalable Java-based backend systems using Spring Framework, with clean RESTful APIs as the backbone of our platform.

• Apply strong knowledge of Java concurrency, multithreading, and asynchronous APIs to deliver high-performance, reliable services.

• Implement security best practices including JWT, OAuth, and web security standards.

• Develop modern, responsive front-end interfaces using React and Redux based on designs and wireframes.

• Optimize components for performance across diverse devices and browsers.

• Conduct code reviews and uphold code quality standards across the team.

• Participate actively in agile ceremonies — standups, sprint planning, reviews, and retrospectives.

• Take ownership of continuous improvement and drive innovation in how we build.

What We're Looking For

• 7+ years of Full Stack experience, with Java as your primary and most recent language — you should be writing Java day-to-day right now, or very recently.

• Strong, hands-on experience with Spring Framework (Spring Boot, Spring MVC, Spring Security).

• Solid understanding of Java concurrency, multithreading, and async patterns — this is non-negotiable.

• Proven experience building and consuming Java-based RESTful web services.

• Significant front-end experience with ReactJS and Redux; AngularJS or VueJS experience is a plus.

• Proficiency in HTML5 and CSS.

• Familiarity with JWT, OAuth, and web security practices.

• Experience with test automation at the unit and integration level.

• Familiarity with cloud infrastructure (AWS, GCP, or Azure), CI/CD pipelines (Jenkins or GitHub Actions), and SaaS development.

• Track record of designing and delivering large-scale, production-grade applications.

• Strong analytical mindset and genuine passion for high-quality software.

• Fluent in written and spoken English.

Work Arrangement:

• Hybrid — onsite Wednesday, Thursday, and Friday (Cebu City).

What We Offer

• The chance to shape a product serving global markets at a publicly listed company (NASDAQ: EGHT).

• Exposure to cutting-edge technologies and modern engineering practices.

• Access to AI-driven productivity tools (Copilot, Gemini, and more).

• A modern Cebu City office with snacks, drinks, and great colleagues.
