Về vị trí này
We are hiring an AI Engineer to design and
operate production-grade AI/ML systems that directly improve
product and operational outcomes. Our current focus is building an AI
Agent Platform with a modular architecture: Gateway à Orchestrator à Agents
→ Tools → Guardrails → Feedback , enabling automation of complex workflows
with strong control, validation and continuous learning. This role is intentionally broader than AI
agents. Depending on priorities, you may also work on:
Search and
retrieval systems (keyword, semantic, hybrid)
Recommendation,
ranking and personalization systems
AI
evaluation, monitoring and reliability systems
Other
AI-powered product or operational systems with measurable business impact
We are not looking for someone who only knows
how to prompt models. We are looking for a strong engineer who can turn
ambiguous problems into reliable systems in production . What
You Will Build
AI Agent
Platform components: orchestration, agent coordination, tool usage,
guardrails and feedback loops
Search and
retrieval systems using keyword, semantic or hybrid approaches
Recommendation,
ranking and personalization systems
Backend
services and APIs that expose AI capabilities safely and reliably
Monitoring,
evaluation and human-in-the-loop workflows for continuous improvement
Responsibilities
Design and
build end-to-end AI/ML systems from problem definition to
production rollout and iteration
Develop
and evolve AI Agent workflows, including context handling, tool calling,
validation and fallback logic
Build
retrieval, search, ranking and personalization components that connect
user intent to the right data or action
Integrate
LLMs with structured and unstructured data via context construction and
tool-enabled workflows
Implement
monitoring, evaluation and guardrails to ensure quality, safety and
reliability

human-in-the-loop mechanisms for low-confidence or high-risk scenarios
Collaborate
with Product, Data and Engineering teams to translate business problems
into practical solutions
Proactively
identify opportunities and improve systems beyond initial requirements
4+ years
of experience in AI Engineering or ML Engineering
Strong
software engineering foundation with a production mindset, strong Python
skills
Experience
building backend services and APIs
Hands-on
experience building LLM-based applications in production

RAG,
embeddings, vector databases
Retrieval
and search pipelines
Experience
in at least one of the following:
AI agent
or multi-step AI workflows
Search,
retrieval or relevance systems
Recommendation,
ranking or personalization systems
Ability to
reason about trade-offs across quality, latency, cost and reliability
Ability to
work through ambiguity and independently drive solutions
Strong
communication and cross-functional collaboration skills
Nice
