Job Description
Role Overview
We build AI-powered applications and demo products spanning conversational agents, retrieval-augmented generation (RAG), computer vision, real-time data pipelines, and applied ML - deployed as containerized services on cloud infrastructure with automated CI/CD.
Our systems work at the prototype/demo level. We're hiring two Senior/Lead AI Engineers to take them to production-grade: reliable, observable, secure, well-tested, and cost-efficient enough to run as real client-facing products, not just demonstrations.
This is a hands-on senior IC role with technical leadership scope - you'll set standards, make architectural calls, and mentor other engineers.
Key Deliverables & Responsibilities
The kinds of problems you'll solve
- Taking LLM-based systems (RAG pipelines, multi-agent workflows, conversational assistants) from "works in a demo" to reliable under real-world, messy, adversarial, or incomplete input.
- Building the evaluation and quality layers most AI teams lack: regression testing for prompts/agents, hallucination and safety checks, retrieval quality measurement, latency/cost/quality tradeoffs.
- Adding the operational maturity that's usually missing from AI prototypes: observability, alerting, retries/fallbacks, security review, and incident-readiness.
- Improving cloud infrastructure and deployment pipelines so services scale, restart cleanly, and cost less to run.
- Deciding, system by system, what "production-ready" actually requires - and pushing back when a shortcut isn't safe to ship.
- Mentoring other engineers and raising the bar on testing, code quality, and documentation across the team.
Tech stack you'll work in
- AI/LLM engineering: LLM application development, RAG, agentic/tool-using systems, prompt engineering, evaluation and guardrails.
- Backend: Python (modern tooling - package managers like uv, linters like Ruff), with some Node/TypeScript.
- Frontend: React-based frameworks ([protected info]), with internationalization considerations.
- Cloud & infrastructure: AWS (containers, serverless functions, CDN/static hosting), infrastructure-as-code, Docker.
- Quality & delivery: End-to-end testing (Playwright or similar), backend test suites, CI/CD pipelines.
Requirements
- 6+ years in software engineering, including 2+ years shipping LLM/AI-powered applications to production - not just prototypes or notebooks.
- Strong, practical experience with RAG and/or agentic AI systems and their real failure modes (bad retrieval, hallucination, tool-call errors, context limits).
- Solid Python; comfortable reading/writing in a JS/TS frontend codebase.
- Experience owning services on a major cloud provider with infrastructure-as-code and containerized deployments.
- Demonstrated ability to make AI systems reliable and measurable - testing, evaluation, monitoring, and cost/performance tuning.
- Good product judgment - able to scope "production-ready" pragmatically rather than gold-plating or cutting corners.
- Good English communication
Nice to have
- Experience with computer vision, structured-data/SQL generation, or real-time data pipelines.
- LLMOps tooling (evaluation frameworks, tracing/observability platforms).
- Security or compliance-sensitive project experience (finance, government, or regulated industries).
- Experience with multilingual or RTL-language products.
Benefits
At SmartOSC, we offer the best to your values:
- You'll take real AI systems the last, hardest mile to production - with the autonomy of a senior engineer and real influence over how the team builds AI going forward.
- Attractive salary package
- Salary review twice a year
- Flexible working hours (between 7:30am - 7:30pm on staff's preference)
- Premium health care
- Working in one of the largest digital transformation agencies in Asia - Professional English environment
- Firm's Certified Qualifications Sponsorship For Career Development
- Annual company trip inside or outside Vietnam
- Other fun activities: happy hour, quarterly team building, football club, yoga club, swimming club, charity activities, etc.
- Free entertainment parties: Birthday party, Anniversary party, Sum-up Party, Year-End Party, etc
