Hire LLM Engineers in Vietnam

What LLM Engineers Earn in Vietnam Working for International Clients

Indonesia's open top runs $2,480 above Vietnam's, yet only Indonesia starts higher. We publish no LLM engineer card, so the table uses our AI engineer rate cards, the closest match. The figures are what engineers in each market earn working directly for foreign companies, before any employer or platform costs.

Monthly ranges from the Remote (Working for International Clients) figures on our rate cards for Vietnam, the Philippines, Malaysia and Indonesia, converted at ExchangeRate-API mid-market rates for 14 September 2026.

The Vietnam card quotes ₫100,000,000 to ₫200,000,000+ a month, converted at ₫25,873 to the dollar. For a hire whose job is training models rather than building products on them, our Vietnam machine learning engineer card quotes $2,500 to $7,000.

Compute sits on top of pay for this role. GPU hours for fine-tuning and token bills for hosted models belong in the brief next to salary.

Through Second Talent you pay one monthly fee that bundles salary, payroll taxes, statutory contributions and our service fee, quoted per role and market. Our pricing page explains the subscription, and our LLM developer cost-to-hire page lists US freelance rates for contract work.

US Pay Benchmark for LLM Engineers

No federal occupation carries the LLM engineer title. An engineer who wires retrieval, prompts and fine-tuned models into a product is writing production software, so the role maps to Software Developers (SOC 15-1252).

Monthly figures are the annual wages on the OEWS profile for 15-1252 divided by 12, rounded to the nearest $10.

A hire who will run pretraining or post-training research sits closer to another occupation. Computer and Information Research Scientists (15-1221) had a national median of $140,300 a year on its OEWS profile.

Salary is only part of the US cost. In the BLS Employer Costs for Employee Compensation release for June 2026, wages and salaries made up 68.5% of employer compensation costs for full-time private industry workers, and benefits the other 31.5%.

Time Zone Overlap: Ho Chi Minh City Against ET, CT and PT

A 5 am to 2 pm shift in Ho Chi Minh City gives a San Francisco team three live hours once US daylight time ends. Only its first hour falls in Vietnam's night-work window. Vietnam keeps UTC+7 all year with no daylight saving, and US clocks stay on daylight time from 8 March to 1 November 2026, per NIST.

The arithmetic for the West Coast: 9:00 am PDT (UTC-7) is 16:00 UTC, which is 11:00 pm in Ho Chi Minh City. Under PST (UTC-8) it is midnight, and a 5:00 pm PST close is 8:00 am the next morning. New York's 9:00 am lands at 8:00 pm under EDT.

Each shift is nine clock hours, including a meal break, counted against a 9 am to 5 pm US day.

LLM work splits well across that gap. Your team files failing traces and eval requests before logging off, and the engineer runs sweeps and fine-tuning jobs in the Vietnamese daytime. The 5 pm to 2 am row then adds live hours with New York for prompt changes that touch production.

Vietnam's Labor Code 2019 counts 22:00 to 06:00 as night work (Article 106) and pays employees at least 30% extra for it (Article 98). Overtime worked at night earns a further 20% on top of the overtime and night rates.

We fix the shift before the offer, which is how our placements get 4-6 hours of daily overlap with US hours.

LLM Engineer Skills to Screen For

Vietnam appears on the supported-country lists for Anthropic and the OpenAI API, so an engineer there can call frontier models without a workaround. The screen below covers open models, evaluation, two Vietnamese rules and the cost of serving.

Vietnamese in open-weight models

AI Singapore's Qwen-SEA-LION-v4.5-27B-IT is fine-tuned on Vietnamese and six other languages from the region, carries an MIT licence and has a 262k context length. Its model card warns that the model has no safety alignment, and tells developers to do their own safety fine-tuning.

The SeaLLMs technical report took another route: continued pretraining of Llama-2 with an extended vocabulary for regional languages. Ask the candidate to tokenize one Vietnamese support ticket under two tokenizers, then explain what the difference does to your monthly bill.

Evaluation in Vietnamese

SEA-HELM scores models on five pillars: NLP classics, LLM-specific tasks, Southeast Asian linguistics, Southeast Asian culture and safety. Vietnamese is one of the five languages it supports.

Give the candidate a model and 50 customer questions in Vietnamese and English, including some typed without diacritics. Ask for an eval that reports a score per language, since an average can hide a failure in one of them.

Disclosure and incidents under the AI Law

Article 11 of the AI Law also covers deployers. They must add a clear notice when AI-generated text given to the public could mislead readers about real events or characters.

Article 12 makes developers, providers, deployers and users responsible for detecting and fixing incidents. After a serious one, the developer and provider must fix, suspend or recall the system and notify the competent agency at the same time.

Under Article 35, systems already running before 1 March 2026 have 18 months to meet the law in healthcare, education and finance. Everywhere else they have 12 months. Ask the candidate how their chatbot would log, flag and roll back a harmful answer.

Personal data in prompts and outputs

Article 10 of Decree 356/2025/ND-CP lets organisations use personal data to research and develop AI systems, as long as they follow the data protection rules. Data derived from inference results must get personal data protection whenever it can identify a person.

The same article requires controllers to tell data subjects about automated processing, explain how the algorithm works and offer an opt-out. Ask the candidate where, in a retrieval assistant built on support tickets, a generated answer could identify a customer, and what they would strip before indexing.

Fine-tuning and serving cost

LoRA reduced trainable parameters 10,000 times and GPU memory three times against full fine-tuning of GPT-3 175B. The vLLM paper raised throughput two to four times at the same latency by paging the key-value cache.

Hand the candidate a labelled Vietnamese dataset and a baseline prompt. Ask whether an adapter, retrieval or a better prompt moves the score most per dollar, and how many GPUs your peak traffic would need.

Contractor or Employer of Record in Vietnam

Software is not one of the nine categories of commissioned work that can be "work made for hire" under 17 U.S.C. § 101, and a copyright transfer must be in writing and signed under § 204(a). List code, prompts, eval sets, adapters and fine-tuned weights in the assignment.

Vietnam's Law on Intellectual Property gives the economic rights in a commissioned work to the party that contracted the author, unless otherwise agreed (Article 39). The author keeps moral rights other than publication (Article 45), and an assignment contract must be in writing (Article 46).

The 2025 amending law, in force since 1 April 2026, added a clause to Article 7. It lets organisations and individuals use lawfully published, publicly accessible documents and data to research, test and train AI systems, if the use does not unreasonably affect authors and rights holders.

Copyrighted material used under that clause must follow Government regulations, so record where each training set came from.

IRS Publication 515 says the place where services are performed determines the source of the income, so an engineer working from Hanoi earns foreign-source income. A foreign individual gives the payer Form W-8BEN to certify foreign status.

Article 13 of the Labor Code looks past the name on an agreement. If it covers a paid job, wages and one party's management and supervision, it is a labor contract. An engineer who owns your eval pipeline full time, on your GPUs and your schedule, fits that description.

Our Employer of Record service employs that engineer in Vietnam, and our Vietnam EOR page covers the details. This is a summary, not legal advice.

English Level and Working Norms in Vietnam

Vietnam's R&D job-function score on the EF English Proficiency Index 2025 is 516, 16 points above the IT score of 500. The national score is also 500, 64th of 123 countries and regions, against a global average of 488, per EF's Vietnam page.

LLM engineers write for models as well as colleagues: system prompts, grading rubrics, model cards. Ask finalists to write a rubric for one of your prompts in English, then grade three model answers against it.

Article 113 of the Labor Code gives employees 12 working days of paid annual leave after a full year. Article 112 adds five paid days for Lunar New Year. Schedule model releases and retraining runs that need a human on call outside the Tet week.

Thanksgiving on 26 November 2026 is a working day in Vietnam, so an engineer there can run an evaluation cycle while your US team is off.

LLM Engineer Hiring Process in Vietnam

Second Talent's vetting covers stages 2 to 5 before you see a profile.

Stage 1: Define what the hire owns You state whether the engineer calls hosted models, fine-tunes open-weight models or serves them on your GPUs. Name the languages your users write in, the compute budget and whether any product reaches users in Vietnam.

Stage 2: Application review We look for a model in production with a written evaluation. That can be a support assistant with before-and-after scores, a fine-tune with a held-out test set, or a serving stack under real traffic. A demo with no numbers does not pass.

Stage 3: Skills assessment The candidate improves a baseline on a small labelled dataset in Vietnamese and English with retrieval, a LoRA adapter or a better prompt. They report scores per language, token cost and the licence of the model they chose.

Stage 4: Live technical interview with a senior engineer A senior engineer reviews the report in English, then runs an incident drill: a chatbot gives a harmful answer to a Vietnamese user. The serving question covers GPU memory for your peak traffic.

Stage 5: Background and reference checks We ask former managers how the candidate's models held up after release, how they handled training data access and how they reported failures. You then choose the contractor or EOR route above.
