System Architect

About Us

We are building a data and services platform in the clean energy sector, connecting IoT devices in the field with a cloud system that processes data in real time. Our product already has devices operating in production, and we are entering the platform expansion phase.

Responsibility

● IoT Core Architecture: Design and evolve the large-scale IoT data acquisition system; ensure high load tolerance, auto-scaling, and low latency in delivery to clients (Web/Mobile).

● Cloud Architecture: Design the overall solution on the Google Cloud Platform (GCP) ecosystem, optimizing operational structure, performance, and infrastructure cost across growth stages.

● Service Planning: Design real-time data pipelines and decompose the system into sub-services and satellite services around the core.

● Modular Architecture: Design the platform for modularity so that new feature groups can be activated on business demand without re-architecting the system.

● Transactional Data Architecture: Shape auditable data models for reconciliation and payment flows — every output must be traceable to its source events.

● Edge–Cloud Contract: Define the device-to-cloud contract: multi-protocol ingestion, OTA firmware fleet management, offline buffering, and backfill.

● Technical Direction: Research and select technologies, storage solutions, and data partitioning strategies; work closely with the Backend team to resolve engineering challenges.

What we are looking for

● Minimum 5+ years of experience building large backend systems, including at least 2 years as an Architect/Tech Lead designing distributed systems.

● Mastery of modern architecture patterns: Microservices, Event-driven Architecture, API Gateway design.

● Deep experience with GCP infrastructure (Pub/Sub, Kubernetes/Containerization…) and message queue solutions.

● Command of the team's stack: Node.js/Python; high-load data model design and optimization on PostgreSQL and MongoDB.

● Security and compliance mindset: multi-tenant access control and personal data protection under Vietnamese regulations.

• ● Able to write and defend Architecture Decision Records with clearly articulated trade-offs.
