Technical Support Engineer — Vietnamese

○ On the radar · talent pool onlyRemoteFULL_TIME / CONTRACTORFocus region: Anywhere

About the role

DogeSMS serves customers in 60+ countries; first-line technical support runs as a follow-the-sun rotation across language regions. This radar role is the Vietnamese-speaking seat in that rotation, focused on Vietnam — one of Southeast Asia's fastest-growing fintech markets, anchored by Momo, ZaloPay, VNPay, and Techcombank. Vietnam's mobile market is dominated by Viettel, VNPT, and MobiFone, with A2P SMS sender ID registration under MIC oversight. Vietnamese fintech support requires familiarity with the country's unique financial product taxonomy (e.g. ví điện tử for e-wallet, mã OTP, mã xác thực) and conversational Vietnamese that handles banking edge cases without sounding mechanically translated. The role is intentionally different from a typical SaaS support seat. Roughly 60% of weekly hours go to working alongside our customer-facing AI agent: reviewing transcripts in Vietnamese, labelling edge cases for retraining, and partnering with the AI Agent Platform team on evaluation datasets that capture region-specific phrasing ('mã OTP', 'mã xác thực', 'ví điện tử', 'tin nhắn xác minh'). The other 40% is direct human support for tickets the agent escalates — integration debugging with customer engineers, payment reconciliation questions, carrier-side delivery investigations. UTC+7 coverage shared with Jakarta seat; covers Vietnamese fintech evening transaction peaks.

What you'll do

  • Own first- and second-line technical support for Vietnamese-speaking customers — primarily async (Intercom / email), with scheduled video sessions for enterprise accounts. Tickets routinely span carrier delivery, API integration, and payment reconciliation.
  • Serve as the language-specific training data partner for our customer-facing AI agent: review Vietnamese agent transcripts weekly, label correctness, build evaluation datasets that cover regional phrasing nuances ('mã OTP', 'mã xác thực', 'ví điện tử', 'tin nhắn xác minh').
  • Translate region-specific technical context for English-language internal hand-offs — when a Vietnamese customer reports a carrier-side delivery issue, the engineer on the other end of the escalation needs the technical detail in English without losing nuance.
  • Maintain Vietnamese versions of customer-facing documentation, status page messaging, and incident post-mortems where customer impact warrants region-specific communication.

What we expect

  • Native or near-native Vietnamese (written and spoken) with technical English at C1+ level — the AI agent training work and internal escalations require fluent English documentation.
  • 2+ years in technical support or technical account management at a developer-facing SaaS, ideally in payments, telecom, or identity / authentication tooling. Experience reading API responses and explaining HTTP error codes to customer engineers.
  • Direct prior experience working alongside AI agents in a support context — you have audited LLM responses, built eval cases, or partnered with an ML team on improving customer-facing agent quality. This is not a "willingness to learn" requirement; it is the primary differentiator for this role.
  • Comfort with the on-call rhythm of distributed-team support: timezone-overlapping with neighboring language seats, English hand-offs at shift change, no expectation of office attendance.
