Job summary

Lingaro Group Philippines is seeking a Senior Fullstack Data Scientist to lead GenAI projects, architect LLM-based solutions, and mentor teams. You will design end-to-end GenAI systems, including data ingestion, retrieval layers, and governance controls.

You should bring 6+ years in data science/AI, 4+ years in production-ready Python AI code, and 2+ years with LLM/RAG development, plus strong English communication and collaboration skills.

Qualifications

6+ years of experience in Data Science/AI engineering.
At least 4+ years of experience in production-ready Python AI-related code development.
At least 2+ years of experience in production-ready LLM-related code development, preferably based on the Retrieval-Augmented Generation (RAG) concept.
Strong analytical and problem-solving skills with the ability to optimize AI solutions for diverse applications.
Strong knowledge and experience in Generative AI, including LLMs, chatbots, AI agents, and RAG mechanisms.

Responsibilities

Lead discovery and solution design for GenAI use cases and translate business problems into architectures (LLM decision, RAGs, fine-tuning, agents, guardrails).
Build end-to-end GenAI applications: data ingestion, retrieval layer, orchestration, API/backend, and simple UI where needed.
Design and implement RAG pipelines with vector databases, hybrid search, rerankers, and evaluation frameworks for relevance and robustness.
Perform model selection, prompting strategies, and fine-tuning for text, code, and multimodal models, including evaluation and A/B testing.
Implement safety, compliance, and governance controls (PII handling, audit logs, human-in-the-loop).
Collaborate with data engineers, product owners, and full-stack developers on scalable architectures and SLAs.

Job description

Growth through diversity, equity, and inclusion. As an ethical business, we do what is right — including ensuring equal opportunities and fostering a safe, respectful workplace for each of us. We believe diversity fuels both personal and business growth. We're committed to building an inclusive community where all our people thrive regardless of their backgrounds, identities, or other personal characteristics.

We are looking for a skilled and experienced Fullstack Data Scientist with solid expertise in Generative AI (GenAI) to lead projects focused on building and implementing advanced systems based on Large Language Models (LLMs), chatbots, AI agents, and Retrieval-Augmented Generation (RAG) mechanisms. As a Senior Data Scientist, you will be responsible for designing, implementing, and optimizing GenAI solutions, as well as mentoring teams. Your knowledge and experience will be crucial in making architectural decisions, selecting technologies, and implementing best practices in AI-driven development.

Tasks:

Lead discovery and solution design for GenAI use cases, translating business problems into concrete architectures (LLM decision, RAGs, fine-tuning, agents, guardrails).
Build end-to-end GenAI applications: data ingestion, retrieval layer, orchestration (e.g. LangChain/LlamaIndex/LangGraph), API/backend, and simple UI where needed.
Design and implement RAG pipelines with vector databases, hybrid search, rerankers, query transformation, and evaluation frameworks for relevance and robustness.
Perform model selection, prompting strategies, and fine-tuning (LoRA/QLoRA/SFT) for text, code, and multimodal models, including evaluation and A/B testing.
Implement safety, compliance, and governance controls (input/output filters, PII handling, audit logs, human-in-the-loop review where required).
Collaborate with data engineers, product owners, and full-stack developers on scalable architectures, SLAs, and integration with existing enterprise systems.
Gather technical requirements and estimate planned work.
Mentor other data scientists/engineers in GenAI patterns, code quality, and best practices; contribute to internal libraries, templates, and reusable components.
Stay current with GenAI landscape (new open and hosted models, agentic frameworks, evaluation techniques) and perform targeted PoCs to validate them.

What We're Looking For:

6+ years of experience in Data Science/AI engineering.
At least 4+ years of experience in production-ready Python AI-related code development.
At least 2+ years of experience in production-ready LLM-related code development, preferably based on the Retrieval-Augmented Generation (RAG) concept.
Strong analytical and problem-solving skills with the ability to optimize AI solutions for diverse applications.
Strong knowledge and experience in Generative AI, including LLMs, chatbots, AI agents, and RAG mechanisms.
Deep understanding of LLM evaluators, validators, and guardrails.
Hands-on experience with one or more GenAI frameworks: LangChain, LlamaIndex, LangGraph, or similar orchestration stacks.
Hands-on experience designing or operating MCP servers/clients for LLM agents
Strong Python skills, including production-grade code, packaging, and testing for data/ML services
Solid understanding of ML/AI concepts: types of algorithms, machine learning frameworks, model efficiency metrics, model lifecycle, AI architectures.
Proven ability to collaborate effectively across technical and non-technical teams.
Familiarity with cloud environments such as Azure (preferred), GCP, or AWS, including AI-related managed services.
Familiarity with CI/CD, testing, and containerized deployments.
Excellent communication skills in English, with the ability to convey complex technical concepts to various audiences.

What Will Set You Apart:

Experience in designing and programming ML algorithms and data processing pipelines using Python.
Good understanding of CI/CD and DevOps concepts, with experience working with selected tools (preferably GitHub Actions, GitLab, or Azure DevOps).
Experience in productizing ML solutions using technologies like Spark/Databricks or Docker/Kubernetes.
Experience with agentic AI development frameworks (e.g., BMAD, multi-agent orchestration, spec-driven AI workflows).

Missing one or two of these qualifications? We still want to hear from you! If you bring a positive mindset, we'll provide an environment where you feel valued and empowered to learn and grow.
