About the Company
OnebyZero is a next-generation Data and AI consulting company, headquartered in Singapore and driving impact across APAC. As an AWS-exclusive partner, we help enterprises modernize data, transform with AI, and apply Generative AI in ways that deliver real business results. Our vision is to make AI adoption both impactful and human-centered. We collaborate with leading enterprises in banking, telecommunications, retail, and other industries to unlock tangible value from data and AI initiatives—going beyond pilots to achieve lasting, scaled impact.
About the Role
We are seeking a Deep Learning Architect with 3–4 years of experience to help design and build production-grade GenAI systems. In this role, you will contribute architecture coverage across the team—reviewing system designs, identifying gaps, and guiding technical decisions at the solution level. You will work on end-to-end LLM system design, Retrieval-Augmented Generation (RAG) pipelines, and multi-agent architectures, with a strong focus on production readiness. Strong coding depth is non-negotiable.
Responsibilities
- Design and contribute to end-to-end LLM system architecture for real-world enterprise use cases (from requirements to production).
- Pre-train, fine-tune LLMs and domain-specific models using techniques such as CPT, SFT, LoRA, and QLoRA for client-specific use cases.
- Design and run model evaluation pipelines to benchmark performance, accuracy, and cost across different fine-tuning approaches.
- Optimise models for latency, throughput, token efficiency, and inference cost in production environments.
- Work alongside agent orchestration and architecture teams to integrate fine-tuned models into multi-agent pipelines.
- Implement prompt versioning, rollback strategies, and model monitoring to ensure reliability post-deployment.
- Translate business requirements from client engagements into model adaptation strategies with clear success criteria.
- Contribute to internal knowledge sharing on fine-tuning best practices, tooling, and emerging techniques.
- Define enterprise integration patterns for GenAI systems (identity/access controls, auditability, data boundaries, governance, and compliance alignment).
- Improve production reliability: latency/throughput optimization, token efficiency, cost control, and robust failure handling.
- Collaborate with cross-functional stakeholders (engineering, data, product, client teams) to deliver high-impact solutions on tight timelines.
- Contribute hands-on code, perform code reviews, and raise the engineering bar through strong software fundamentals.
Qualifications
- 3–6 years of experience in ML engineering, LLMs, or model development roles.
- Hands-on experience with Continual Pre-training (CPT), Supervised Fine-tuning (SFT), LoRA, or QLoRA on LLMs.
- Strong Python programming skills—ability to write clean, testable, production-ready code.
- Experience running model evaluation and benchmarking pipelines in a structured way.
- Solid understanding of transformer architectures and how fine-tuning affects model behaviour.
- Experience deploying fine-tuned and pre-trained models to cloud environments with attention to cost and latency.
- Strong problem-solving skills with the ability to work independently on client-facing projects.
- Solid software engineering fundamentals: APIs, data structures, testing, debugging, and performance optimization.
- Ability to review designs, communicate trade-offs clearly, and collaborate effectively in a fast-paced environment.
Required Skills
- Experience with AWS-native GenAI building blocks (e.g., Bedrock, OpenSearch, Lambda, ECS/EKS) and secure enterprise deployments.
- Experience with vector databases/search engines (OpenSearch, Pinecone, Weaviate, Milvus, FAISS) and retrieval optimization.
- Experience with containerization and orchestration (Docker, Kubernetes).
- Experience building evaluation/observability pipelines for LLM systems and implementing safety/guardrail patterns.
- Consulting or client-facing delivery experience.
