Job description for Senior Fullstack Engineer at PT Karsa Omni Teknologi Adicipta
We’re looking for a Senior Fullstack Engineer to architect scalable, secure, and observable services.
You don’t just write code; you own the entire application lifecycle. You understand that a great frontend experience is useless if the backend buckles under load, and that clean APIs mean nothing if they can't be deployed reliably. If you’ve designed systems, optimized databases, and pushed code to production with confidence, this is your kind of challenge.
What You’ll Do:
✅ Design, build, and maintain fullstack applications using modern JS/TS (React/Next.js) and backend frameworks (Node.js or Python)
✅ Architect scalable, secure, and observable services with clean REST/GraphQL APIs
✅ Take ownership of deployment, monitoring, and operational health of services in production
✅ Contribute to CI/CD pipelines, infrastructure decisions, and developer experience
✅ Mentor mid/junior engineers through code reviews, pairing, and system design discussions
Who You Are:
✅ 5+ years in fullstack development with a strong grasp of both frontend and backend architecture
✅ Deep understanding of state management, testing, performance optimization, and API design
✅ Experience deploying in cloud environments (AWS/GCP/Azure)
✅ Strong preference for experience with Kubernetes (K8s), Docker, and containerized workflows
✅ Fluent in English — written and spoken
✅ Collaborative, pragmatic, and passionate about building sustainable, observable software
