Tech Lead (Full-stack)

• Own the technical architecture, design, and quality of scalable, secure, high-performance full-stack systems, ensuring they meet product and business requirements. 

• Lead technical design and architecture reviews, setting technical direction and selecting the technologies, frameworks, and implementation approaches the team will use. 

• Mentor, coach, and grow a team of engineers through code reviews, technical guidance, and hands-on pairing, raising the overall engineering bar. 

• Drive diagnosis and resolution of complex system issues across application, infrastructure, network, and service layers, and put in place practices that prevent recurrence. 

• Partner closely with Product Owners, Business Analysts, and key stakeholders to shape technical strategy, translate business requirements into robust and maintainable solutions, and inform product roadmap decisions. 

• Stay hands-on — remain an active contributor who ships production code alongside the team, not only architecture and oversight. 

• Establish and enforce engineering best practices: code quality standards, CI/CD processes, technical documentation, and system reliability. 

• Take full ownership and accountability for the team's technical deliverables, operating effectively in a fast-paced, high-impact startup environment. 

Technical Skills 

• 7+ years of professional software engineering experience, including experience leading technical design or mentoring engineers in a senior/lead capacity. Experience with AI products is a strong advantage. 

• Proven ability to both architect systems and ship production code — this role requires hands-on coding, not just design and oversight. 

• Strong hands-on experience across the full stack, with deep expertise in: 

• Frontend: Modern JavaScript frameworks (e.g., React, Next.js) 

• Backend: Python/TypeScript (experience with Go or Rust is a strong plus) 

• Experience working with both SQL and NoSQL databases, and designing data architecture for scalable systems. 

• Solid understanding of CI/CD pipelines, deployment processes, environment configuration, and system observability/monitoring. 

• Demonstrated experience mentoring or leading engineers, conducting code/design reviews, and driving technical decision-making within a team. 

• Strong communication skills in Vietnamese and English, including the ability to communicate technical concepts to non-technical stakeholders; Japanese proficiency is an advantage. 

Professional Attributes 

• Balance technical excellence with pragmatic delivery of features and products, making sound tradeoffs under time and resource constraints. 

• Comfortable making technical decisions and setting direction under uncertainty and evolving requirements. 

• Able to lead and influence cross-functional teams while working independently on complex technical problems. 

• Strong sense of ownership, accountability, and product mindset, extending beyond individual tasks to the team's overall technical outcomes. 

• Coaching mindset — genuinely invested in growing the skills and careers of the engineers around them.

• Competitive salary, negotiable based on experience and skill level. 

• Performance-based bonuses and potential stock options. 

• Flexible work (remote/hybrid options) within a young, tech-driven culture. 

• Rapid career growth: further leadership growth (e.g., Engineering Manager, Head of Engineering) and international exposure (e.g., Japan, USA). 

• Premium insurance (health, social, unemployment) in accordance with FPT standards. 

• Engaging company culture with team-building activities, sports, and retreats. 

• Equipment provided based on work requirements up to USD 2,500.
