Senior Fullstack Developer

Team: Tech

Location: Ho Chi Minh City, Da Nang City, Hanoi, Bangkok

Commitment: Fulltime

Workplace Type: hybrid

The kind of person we're looking for:

• You're the kind of engineer who gets energized by new contexts, new stacks, new problems. You've been around long enough to pick things up fast, ask the right questions early, and make good calls with incomplete information. You can explain not just what you built but why, and why you chose it over the alternatives.
• You work well with clients. You communicate clearly, flag issues before they become problems, and know how to build trust with people you've never met in person. Senior engineers here don't just take requirements, they shape them.
• And you're genuinely curious about AI tools, about better ways of working, about what's happening outside your immediate lane. You share what you learn, not just apply it yourself.

In this role, you will:

• Work directly with international clients to understand what they're building and why, then help shape the technical direction, not just execute it.
• Lead delivery on complex workstreams, making architectural decisions and setting standards for the work around you.
• Think beyond the ticket in front of you: understand the business impact of your decisions, flag trade-offs early, and push back when something doesn't make sense.
• Mentor and elevate the engineers you work alongside through code reviews, shared context, and honest feedback.
• Share what you learn: a useful AI prompt, a pattern that worked, a mistake worth avoiding.

What you will bring:

• 7+ years of professional software engineering experience, with a track record of owning and delivering complex projects end-to-end.
• Experience working on international projects, ideally with European clients or teams.
• A career that shows you've worked across multiple domains and picked up different stacks along the way, not because the job required it, but because you're genuinely curious.
• Our clients tend to operate in e-commerce, travel, fintech, healthcare, and logistics. Deep experience in at least one or two of these domains enough to understand the business, not just the codebase.
• Our common stacks lean toward React or Vue on the frontend, PHP, Node.js, Go, .NET, or Java on the backend, and AWS or GCP for infrastructure. We don't expect you to know all of them, but we do expect you to have moved between a few and have strong opinions about why.
• Hands-on use of AI coding assistants (Cursor, Claude, Copilot, etc.) as part of your actual workflow, and the judgment to know when to trust them and when not to.
Nice to have
• Experience building AI-powered features or working on AI Agent systems.
