Mô tả công việc
We‘re looking for a Senior Fullstack Engineer with a strong Computer Science foundation who can own the full product lifecycle - from system architecture to end-user experience. You‘ll help build real-world web and AI-powered platforms, tackling hard problems around performance, scalability, and reliability.
WHAT YOU‘LL DO:
-
Design, build, and operate end-to-end fullstack features (frontend, backend, database, deployment).
-
Make sound architectural decisions and technical trade-offs grounded in core CS principles.
-
Uphold code quality through reviews, testing, and clear technical documentation.
-
Optimize system performance (frontend rendering, API latency, queries, caching).
-
Collaborate with product, design, and fellow engineers; mentor junior team members.
TECHNICAL REQUIREMENTS
-
5+ years of software engineering experience, including hands-on fullstack work.
-
Strong Computer Science fundamentals: data structures & algorithms, database internals, networking, concurrency, and system design.
-
Frontend: proficient in React and Next.js (SSR/SSG/ISR, App Router, state management, performance tuning).
-
Backend: strong in at least one production stack. We prefer NestJS/Node.js, Python, or Rust, but are open to any technology if your fundamentals are solid.
-
Solid experience designing RESTful/GraphQL APIs, working with SQL & NoSQL databases, and applying common architectural patterns.
-
Comfortable with Git, CI/CD, containerization (Docker), and cloud environments.
Nice to Have
-
Experience with microservices and message queues (Kafka, RabbitMQ, Redis).
-
Practical experience applying AI in real products — integrating LLMs, building RAG pipelines, or working with vector databases.
-
Proficiency using AI-assisted development tools (e.g. Claude Code, Copilot, Cursor) to boost engineering productivity.
-
Experience with 3D web (Three.js/React Three Fiber) or realtime/WebSocket systems.
-
Open-source contributions or personal projects that demonstrate technical depth.
-
Experience mentoring or leading a small team.
---------------------------------
Unique benefits:
- Social insurance coverage upon signing your employment contract.
- Generous leave policy: 12 annual leave days plus all Vietnamese public holidays.
- 13th-month salary (applicable from the probationary period).
- Company-provided equipment.
- Well-stocked pantry: tea, coffee, snacks, microwave, etc.
- Engaging company activities: Company trips, team-building events, regular internal events (including live music performances!), and access to company-sponsored badminton courts.
