Scope of Work:

• Design and build backend services with Golang and TypeScript that are secure, scalable, and maintainable.

• Develop REST/gRPC APIs and asynchronous processing with queues/streams (Kafka/RabbitMQ/NATS).

• Work with PostgreSQL and Redis, including schema design and query performance tuning.

• Establish CI/CD, automated testing, and observability (logging/metrics/tracing) for production systems.

• Design and develop frontend applications with React (Next.js) that are responsive, accessible, and maintainable.

• Integrate frontend applications with backend APIs, manage state using Redux Toolkit or React Query, and ensure smooth data flow across the stack.

• Collaborate with designers to implement pixel-perfect, user-friendly interfaces and ensure consistent UX across web platforms.
• Co-design architectures (Clean/Hexagonal/DDD) with Product, QA, Infra, and Security teams.
• (Optional) Integrate internal Web3/blockchain services where applicable.

Job Description:

• Implement microservices using Go (Gin/Echo/Fiber) and TypeScript (NestJS/Express), plus background workers/schedulers.

• Develop and maintain frontend applications with React (Next.js), implementing responsive, accessible, and reusable UI components.

• Integrate frontend applications with REST/gRPC APIs, handle authentication flows, and manage state with Redux Toolkit.

• Optimize frontend performance, bundle size, and rendering speed, ensuring smooth user experience and adherence to web vitals metrics.

• Define API contracts, manage Protobuf/OpenAPI specs, and maintain API versioning.

• Author robust tests (unit/integration/contract) with go test/testify, Jest, etc.

• Build and maintain Docker/Kubernetes pipelines on AWS/GCP with GitHub Actions/GitLab CI.

• Operate monitoring/alerting (Prometheus/Grafana, OpenTelemetry) and do performance profiling (pprof).

• Enforce application security (authn/authz, OWASP) and conduct regular code reviews.

• Write technical docs, pair program, support agile ceremonies, and participate in on-call rotations.

• Collaborate closely with Product, Design, QA, and Infrastructure teams to deliver high-quality, reliable, and user-focused features.

• Bonus: Build Flutter (Dart) for mobile development, integrating APIs/sockets with proper state management (Bloc/Riverpod) and release pipelines.

Qualification & Requirement:

Must-have

• Bachelor’s in CS/CE or equivalent experience; we prioritize impact and depth over tenure.

• Proficiency in Golang and/or TypeScript/Node.js (including Go concurrency patterns).

• Strong foundation in data structures/algorithms and system design (scalability/reliability).

• Hands-on with PostgreSQL and Redis.

• Knowledge of REST/gRPC, API versioning, and secure API practices (JWT/OAuth2/Key management).

• Practical experience with Git/CI/CD, Docker, basic Kubernetes, and production observability.

• Clear communication, cross-functional collaboration, and strong ownership.
• Thai/English for technical work (read/write).

Nice-to-have / Bonus

• Flutter (Dart) for mobile (Bloc/Riverpod, Clean Architecture, Fastlane/Firebase) ★ Bonus

• Kafka/RabbitMQ/NATS; event-driven architectures
• GraphQL, WebSocket, real-time systems
• OpenTelemetry, ELK/OpenSearch, SLO/Error budget, chaos/load testing
• Web3/blockchain familiarity (optional)
• Practical security (secret management, least privilege, SAST/DAST)
• Container Technology such as docker
