Key Responsibilities
Microservices design & development: design and build micro services-based with [protected info] (NestJS/TypeScript), Go, or Python following Domain-Driven Design principles; own services end-to-end from API contract through to production deployment.
API engineering: build and optimize RESTful APIs and gRPC services serving millions of requests per hour; define and maintain API contracts in collaboration with Mobile and Frontend teams.
BFF & integration layer: build Backend-for-Frontend services connecting the OneVN platform with VNeID, eKYC providers, payment gateways (VNPay, MoMo, ZaloPay), and government service endpoints.
Event-driven architecture: implement and operate event-driven systems with Apache Kafka and NATS - pub/sub, event streaming, and message queuing for asynchronous business flows.
Data layer: design schemas and optimize PostgreSQL for high-volume data: indexing, partitioning, query optimization, and execution plan analysis.
Resilience engineering: ensure high availability across services: circuit breaker, retry logic, rate limiting, timeout, and graceful degradation patterns applied consistently.
Kubernetes operations: deploy and maintain services on Kubernetes: write Helm charts, configure HPA, manage resource quotas, and troubleshoot workload issues in production.
Authentication & identity: implement OAuth 2.0, JWT, and OpenID Connect flows - with specific experience or strong willingness to integrate VNeID authentication at the platform level.
Testing & code quality: write unit and integration tests with high coverage; participate actively in code review; contribute to and uphold team engineering standards.
Cross-functional collaboration: work closely with Mobile, Frontend, and DevSecOps teams to define API contracts, unblock integrations, and deliver features end-to-end.

Proficiency with Docker and CI/CD pipelines (GitLab CI / GitHub Actions) for containerized services.
Clear understanding and implementation experience with OAuth 2.0 and JWT authentication in distributed environments.
Solid grasp of resilience patterns: circuit breaker, retry, timeout, and bulkhead - and when to apply each.

Salary range: 40,000,000 - 65,000,000 VND/month, negotiable based on experience and technical depth.
13th-month salary.
Work on a national-scale platform serving millions of users - real distributed systems challenges, not CRUD microservices.
Collaborative and technically driven team; regular tech sharing sessions and code review culture.
Opportunities for career growth into Tech Lead or Platform Architect roles.
Company benefits in accordance with labor law (insurance, annual leave, etc.).
