About the Job
We’re a profitable company with ~$800M in revenue, growing quickly and executing a clear strategy toward $1B+. In Vietnam, we operate as a product-focused, lean team embedded with our US partners. This role is based in Ho Chi Minh City (Saigon) and works directly with the US team, focusing exclusively on the US market (not Vietnam).
Work LocationThanh My Loi (Diamond Island), Ho Chi Minh City, Vietnam
The Opportunity
We operate an engineering environment where speed is no longer limited by tooling—but by engineering judgment.Our development workflow is highly optimized, allowing engineers to ship, test, and debug significantly faster than in traditional teams. This creates a new standard: each engineer is expected to deliver more, move faster, and still maintain high-quality systems.You will be joining an experienced, fast-moving engineering team where systems are already running in production at scale. You will be contributing to and improving an existing system alongside strong engineers. This role works directly with our colleagues based in the US with the possibility for on-site training in the US.This role is designed for senior engineers (7+ years of experience) who have built and operated systems through the full development lifecycle—before modern acceleration tooling existed—and understand what “good” looks like at every layer: code, design, architecture, and production.
In this environment:

In this environment:
- You’ve seen how systems break in production—and know how to prevent it
- You’ve debugged issues the hard way—and can now resolve them faster with better tools
- You understand trade-offs—and can make decisions that scale beyond immediate requirements
- Modern tooling helps accelerate execution, but correctness, scalability, and maintainability still depend on your judgment.
We are looking for engineers who can combine:
- Strong fundamentals built over years of experience
- Deep system thinking and architectural awareness
- The ability to operate at high speed without losing control of the system
Responsibilities
This is a Principal / Senior software engineer position with high ownership, where your impact is measured directly by what you build and ship to production.
Key Responsibilities
Key Responsibilities
- Build and ship production systems at a higher pace than traditional teams, while maintaining correctness and stability
- Take ownership of systems end-to-end: from design and implementation to deployment, monitoring, and production behavior
- Make fast, high-quality engineering decisions—knowing when to move quickly and when to slow down to avoid long-term problems
- Use AI tools to accelerate development, testing, and debugging, while validating outputs and ensuring code and system behavior are correct
- Debug production issues efficiently, using available tooling to quickly narrow down root causes and ship reliable fixes
- Review code and system designs critically, and call out incorrect logic, weak abstractions, and scalability limitations early
- Design systems that go beyond immediate requirements, avoiding short-term solutions that break at scale
- Continuously improve existing systems by reducing complexity, fixing hidden issues, and making them easier to operate
- Work closely with product and other engineers to turn ideas into systems that perform reliably in production
Minimum Qualifications
- 7+ years of professional software engineering experience, with a strong track record of building and operating production systems
- Proven experience designing and maintaining scalable systems under real-world usage, not just feature development
- Strong English proficiency is required, with the ability to clearly explain complex technical solutions and collaborate effectively within the team
- Strong backend engineering skills in at least one language: Node.js, Python, Java, Go, or similar
- Solid understanding of system design, including:
- Distributed systems
- Micro-services or event-driven architectures
- API design, scalability, and performance trade-offs
- Hands-on experience working with production systems, including:
- Strong engineering judgment, able to identify incorrect logic, weak abstractions, and poor design decisions early. Understands long-term trade-offs, not just immediate solutions
- Experience with cloud infrastructure (AWS, GCP, Azure) and modern development practices
- Comfortable working in a high-velocity environment, with the ability to maintain quality while moving fast
- Experience using AI-assisted development tools (e.g., code generation, debugging support), with the ability to validate and correct outputs rather than relying on them blindly
Preferred Requirement
- Experience working on high-scale systems (e.g., e-commerce, fintech, logistics, marketplaces) with real user traffic
- Experience optimizing system performance, scalability, and reliability under production load
- Experience improving engineering velocity through better tooling, automation, or development workflows
- Familiarity with loyalty systems, promotions engines, personalization systems, or customer engagement platforms.
- Familiarity with full-stack development with the ability to contribute across the stack when needed
- Experience working with data-intensive or real-time systems
- Experience contributing to system design decisions beyond individual features (e.g., architecture evolution, service boundaries, scaling strategies)
- Familiarity with systems operating in regulated environments (e.g., payments or compliance-driven platforms)
Benefits
- Salary: Negotiable
- Competitive package
- Hybrid working model
- Macbook Pro provided for work
- Bonus: 13th month salary
- Weekly learning sessions and offsites
- Close-knit small team culture
- Work from home every Wednesday
- Fluency in English (must have)
- Product mindset, prefer to have experience and interest in AI
- Follow Vietnam work hours and include meetings with US Team
- To submit candidates, please note along with CV: summary of skills & experience, salary expectation, notice period, English audio file, confirmation if candidate is willing to work in office (in Diamond island)
- 3 rounds
