About Us

JC Computing VN is a technology startup based in Ho Chi Minh City, Vietnam. We are building a next-generation EdTech SaaS ecosystem to modernize how schools and educational institutions manage their operations.

Overview

We are looking for a highly skilled fullstack (Bakend focus) Engineer with deep expertise in designing, building, and operating scalable, secure, and high-performance backend systems. The ideal candidate has strong hands-on experience with modern backend frameworks, distributed system design, cloud infrastructure, and production deployment strategies.This role requires not only strong coding ability, but also system-level thinking — understanding how services interact, how data flows, how systems scale, and how reliability, security, and performance are ensured in real-world environments. You will work closely with frontend engineers, product owners, DevOps/platform teams, and stakeholders to deliver robust backend services that power mission-critical features across our platform.

Key ResponsibilitiesBackend Engineering

• Design, develop, and maintain scalable backend services using Nestjs
• Build clean, well-structured APIs (REST and/or GraphQL) with clear data contracts, validation, and error handling.
• Implement complex business logic, workflows, and domain models with strong separation of concerns.
• Ensure backend code is maintainable, testable, and production-ready, following best practices and coding standards.
• Optimize backend performance (query optimization, async processing, background jobs, batching, caching).

System Design & Architecture

• Make architectural decisions around service boundaries, data ownership, and communication patterns.
• Collaborate on system-wide design topics such as:
• API versioning and backward compatibility
• Data consistency and transactional boundaries
• Caching strategies (in-memory, Redis, HTTP caching)
• Event-driven vs request-driven workflows
• Participate actively in technical planning, design reviews, and architecture discussions.

Infrastructure & Deployment

• Collaborate on CI/CD pipelines to ensure safe, automated, and repeatable deployments.
• Understand and apply deployment strategies such as Rolling updates
• Monitor, debug, and improve system reliability using logs, metrics, and tracing.

Collaboration & Leadership

• Mentor junior and mid-level backend engineers and support team knowledge-sharing.
• Work closely with frontend engineers to align API design with client needs.
• Communicate effectively with DevOps, security, and infrastructure teams.
• Take ownership of backend components from concept to production and long-term maintenance.
• Identify technical risks early and propose pragmatic, scalable solutions.

QualificationsRequired Skills

• 3+ years of professional experience in backend development with Node.js
• Strong experience designing and maintaining RESTful and GraphQL APIs.
• Proficiency with relational and NoSQL databases.
• Strong understanding of authentication, authorization, and backend security fundamentals.

Backend Knowledge (Required)

• Hands-on experience and conceptual understanding of at least one backend framework NestJS.
• Ability to design API contracts, understand service architecture, and collaborate effectively with backend teams.

Cloud & DevOps Knowledge (Required)

• Hands-on experience with Docker and containerized applications.
• Experience with CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, etc.).

Good to Have

• Experience with microservices or modular monolith architectures.
• Experience operating production systems (monitoring, logging, incident response).
• Experience with performance testing and load testing.
• Familiarity with compliance, data privacy, and security best practices.
• Experience working in multi-tenant SaaS systems.

What We Offer

• Opportunity to lead and influence backend and platform architecture decisions.
• Challenging problems involving scale, reliability, and real-world constraints.
• Collaborative, engineering-driven culture with strong technical ownership.
• Modern cloud-native stack and production-grade systems.
• Impactful work across large-scale, mission-critical platforms.
