CÔNG TY CỔ PHẦN SMARTOSC

We are looking for a hands-on Technical Lead who owns the technical direction of complex, large-scale systems end to end. This is not a UI-focused role and not a Solution Architect role — we need someone who can stand back and explain a system's overall architecture clearly, then drill down into any layer with real depth, while remaining strongly hands-on in backend development (Node.js) and capable across the frontend. You will lead and mentor a delivery team, be accountable for technical quality, and work directly with regional and client-side stakeholders

Key Deliverables & Responsibilities

• Own the end-to-end technical design and architecture of assigned systems — able to articulate the overall architecture (components, request/data flow, integrations, where data lives) and justify the trade-offs behind it.
• Drive hands-on development with a primary focus on backend services in Node.js, plus meaningful contribution on the frontend (React/Next.js).
• Lead, mentor, and manage a team of engineers: assign work, review code, set standards, and grow the team's technical capability.
• Translate client and business requirements into robust technical solutions, and clearly explain technical decisions to both technical and non-technical stakeholders.
• Take ownership of non-functional requirements — performance, scalability, reliability, security — and identify where a system will break first under load.
• Collaborate with cross-functional and regional teams (e.g. product, QA, and other engineering squads across markets) and with infrastructure teams on deployment.
• Uphold engineering best practices: code quality, testing, CI/CD discipline, and technical documentation.
