About Belle.ai
Headquarters: Belle Torus (Belle.ai) is a global corporation specializing in artificial intelligence, focusing on image recognition and processing solutions based on artificial intelligence. Belle is present in 4 countries: the USA, France, Vietnam, and Indonesia.
Vietnam Branch: Belle Asia is a wholly owned division of the Belle Torus Corporation, serving as the primary hub for all Vietnam-based operations, managing the workforce that includes our AI, Product and Engineering divisions, our Asia Sales team as well as a customer support center for all markets.
Location: Hanoi, Vietnam (Global Collaboration: US, France, Vietnam)
Employer: Belle Asia Ltd .,
Employment Type: Full-time
Position: Technical Team Lead
Belle.ai is looking for a Technical Team Lead who acts as a true "Product Founder" on the engineering side, focusing on the application of AI in medicine. You will serve as the technical backbone for our entire product ecosystem, not just a single application.
This role is ideal for someone who is product-driven, ambitious, curious, and not afraid to step outside pure engineering to learn medical knowledge.
You will lead the engineering execution across two critical evolutionary stages of the company:
Search for Product-Market-Fit (PMF): Rapid experimentation and "build fast, learn fast."
Growth \& Scale: Transforming successful MVPs into robust, scalable enterprise-grade systems.
Mindset (very important)
Curious and eager to learn — even as an engineer, you’re excited to learn medical concepts
Product-oriented: you want to build things that ship and make impact
Ambitious and driven: you aim high, take initiative, and are not afraid of challenges
Creative and innovative: always looking for better ways to solve problems
Growth mindset: motivated to improve, level up, and move forward
Fearless attitude: comfortable with uncertainty, experimentation, and change
Key Responsibilities
1. Holistic Technical Ownership (All Products Scope)
You are responsible for the technical integrity of the entire platform, covering both Consumer (C) and Business/Provider (B) sides:
Consumer Ecosystem: Build high-engagement mobile apps (React Native/Flutter) for users to scan skin, track progress, and receive AI advice.
Provider \& Internal Ecosystem: Architect and develop complex Web Portals for Dermatologists, Clinics, and internal Admin tools to manage data and interactions securely.
AI \& Core Integration: seamless integration of AI models, LLM APIs, and RAG pipelines across all products (Consumer App \& Doctor Dashboard).
2. Dual-Mode Engineering Execution
Stage 1: The "Speed Lab" (Pre- Product-Market-Fit (PMF) / Feature Discovery)
Build Fast, Learn Fast: Lead the squad to ship MVPs and experimental features in record time. Your goal here is validating market hypotheses, not writing perfect code.
Vibe Coding / AI-Augmented Speed: Actively utilize AI coding assistants (Cursor, Copilot, etc.) to accelerate development. You embrace the "10x Engineer" mindset to bypass boilerplate and focus on shipping value.
Rapid Prototyping: Be comfortable with throwing away code if a feature doesn't stick. Prioritize speed-to-market and user feedback loops.
Stage 2: The "Scale Engine" (Post-PMF / Growth)
Robust Architecture: Once a product/feature hits PMF, shift gears to a long-term mindset. Lead the refactoring of "hacky" MVP code into a stable, secure, and scalable architecture.
Scalability \& Performance: Ensure the system handles high concurrency and data loads as our user base and provider network grow globally.
System Reliability: Establish rigorous standards for security (HIPAA/GDPR compliance mindset), testing, and uptime for our critical Provider Portals and Consumer Apps.
3. Technical Leadership \& DevOps
Lead the Squad: Mentor a nimble team of developers. Conduct code reviews that adapt to the context: lenient on structure during prototyping, strict on quality during scaling.
Communication: Communicate clearly with managers and give helpful, professional feedback to team members to build a positive and effective working environment.
Incident Management:
Primary technical point of contact during critical system failures or high-priority incidents, leading the investigation and rapid recovery to minimize business disruption.
Provide clear, timely, and non-technical updates to stakeholders (PO, Management) regarding incident status, impact, and estimated time of recovery (ETR).
Lead post-incident reviews to identify underlying technical or process gaps; ensure the team implements permanent fixes rather than temporary workarounds.
Efficiently organize and delegate tasks among team members during emergencies, ensuring balanced effort and preventing burnout while maintaining 24/7 service stability.
DevOps Autonomy: Manage CI/CD pipelines and cloud resources (AWS/GCP/Firebase) to ensure the product team is self-sufficient and unblocked.
Data-Driven Iteration: Implement analytics (Mixpanel, Amplitude) deeply into both Consumer and Provider products to drive product decisions.
Requirements Must-Haves
Experience:
10+ years of Fullstack engineering experience. Must have a portfolio demonstrating ability to build complex ecosystems (Consumer Apps + Admin/Provider Dashboards).
Have experience leading cross-functional teams, setting clear goals, taking responsibility for the team’s work, and supporting members to improve their skills and performance.
Dual Mindset: Demonstrated ability to switch between "Hacker Mode" (getting things done fast) and "Architect Mode" (building for scale and stability).
True Fullstack: Fluent in shifting context between Mobile UI (React Native/Flutter), Backend Logic (Python/Node.js), and Admin Web Apps (React/Next.js).
The "Vibe Coding" Senior: You are an expert at prompting AI to generate code blocks, refactors, and debugs to maximize velocity.
Startup DNA: You thrive in ambiguity. You are willing to "wear many hats"—from fixing a server config to tweaking a CSS animation for better UX.
English: Fluent English is mandatory for global collaboration.
Nice-to-Haves
Experience with Generative AI products (wrapping LLMs, image generation).
Previous experience in HealthTech, Telemedicine, or Booking platforms.
Experience transitioning a product specifically from MVP to Series A/B scale.
The Culture Fit: "Builder over Architect"
We prefer working software over comprehensive documentation.
We prefer rapid iteration over perfect architecture, but we must track Technical Debt and have a plan to refactor as soon as the feature is validated.
We value user empathy over technical purity.
Why Join Belle.ai ?
Direct Impact: You play a pivotal role in product realization. Your work directly shapes the entire user and provider experience.
Global Exposure: Work with top-tier AI researchers in France and Business leaders in the US.
Ownership: You own the technical roadmap for the entire product suite.
Compensation: Competitive salary + Stock Options (ESOP).
Job Type: Full-time
