Remote Technical Lead Full-Stack

Top 3 Reasons To Join Us The Job

About the Role 

We are seeking an experienced Technical Lead (Full-Stack) to join our team on a freelance contract basis.
This position is being advertised through our recruitment partner in Vietnam. The successful candidate will provide services to a Singapore-based technology company and will work closely with our regional team on project delivery and client engagements.

In this role, you will own the architecture, mentor a team of talented  engineers, and partner closely with Product and Business stakeholders to deliver high-impact products that serve millions of users. If you are passionate about building scalable systems, growing engineering talent, and shaping the technology roadmap of a fast-moving product, we would love to hear from you. 

Key Responsibilities 

• Lead, mentor, and grow a team of full-stack engineers — provide technical guidance, conduct code reviews, and foster a culture of engineering excellence and continuous learning. 
• Own the end-to-end technical architecture of products and services: design scalable, secure, and maintainable systems aligned with business goals and long-term product strategy. 
• Partner with PM and cross-functional stakeholders to translate high-level business requirements into clear technical roadmaps, milestones, and deliverables. 
• Drive technical decision-making — evaluate trade-offs, select appropriate technologies, frameworks, and tools, and define coding standards and best practices across the team. 
• Oversee the full software development lifecycle: planning, estimation, design, implementation, code review, testing, deployment, monitoring, and post-release support. 
• Conduct hands-on development on the most critical and complex components of the system, while balancing leadership responsibilities. 
• Define and enforce documentation standards for technical designs, system architecture, APIs, workflows, and operational runbooks. 
• Establish and maintain robust CI/CD pipelines, automated testing strategies (unit, integration, end-to-end), and DevOps best practices. 
• Benchmark, troubleshoot, and continuously optimize application performance, scalability, reliability, and cost-efficiency. 
• Identify, evaluate, and mitigate technical risks; lead incident response and root-cause analysis for production issues. 
• Champion the adoption of modern technologies — including AI-assisted development, AI Agents, and emerging tooling — to accelerate delivery and improve product quality. 
• Collaborate with hiring managers to interview, recruit, and onboard engineering talent; contribute to team planning and resource allocation. 
• Communicate technical concepts clearly to both technical and non-technical audiences, including senior leadership and external partners. 
• Drive a culture of accountability, ownership, and quality across the engineering team. 
• Comfortable to engage with end user clients to understand requirements and perform business analysis.

• Strong hands-on expertise in Node.js, JavaScript, TypeScript, and Golang. 
• Solid front-end experience with Angular and/or ReactJS. 
• Deep knowledge of PostgreSQL — schema design, query optimization, indexing, and scaling strategies. 
• Strong proficiency with Docker, container orchestration, and modern deployment workflows. 
• Hands-on experience with cloud platforms (AWS, GCP, or Azure), microservices architecture, and event-driven systems. 
• Strong understanding of CI/CD pipelines, infrastructure-as-code, observability, and DevOps best practices. 
• Solid grasp of modern AI concepts and ecosystems — MCP, AI Agents, Agentic workflows, and LLM-based application design. 
• Proven experience using AI-assisted coding tools such as Claude, Codex, Cursor or similar. 
• Excellent system design skills with the ability to make sound architectural trade-offs. 
• Strong leadership, mentoring, and people-development skills — able to grow engineers and build high-performing teams. 
• Excellent communication skills in English (both written and verbal) and the ability to influence stakeholders at all levels. 
• Experience performing Business Analyst-style responsibilities: requirement gathering, solution analysis, and functional clarification. 
• Comfortable working remotely with distributed teams across time zones. 
• Immediately available or with a notice period of no more than one month is preferred. 

Nice to Have 

• Experience leading product teams in infrastructure, building management, IoT or other high-traffic consumer products. 
• Experience building and deploying services using AWS Cloud Services. 
• Contributions to open-source projects or technical thought leadership (talks, blogs, papers). 
• Experience designing AI-augmented products or integrating LLMs into production systems. 
• Familiarity with security best practices, data privacy, and compliance frameworks.

Why You'll Love Working Here
