Production-Ready GenAI LLM Systems Architect

TechKnowledgey Pte Ltd; Singapore; On-site; SGD 150,000 - 190,000; Full time

Job summary

TechKnowledgey Pte Ltd seeks a Deep Learning Architect with 3-4 years of experience to design and build production-grade GenAI systems. You will contribute architecture coverage across 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.

Qualifications

• 3-6 years of experience in ML engineering, LLMs, or model development roles.
• Hands-on experience with CPT, 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.
• Experience with AWS-native GenAI building blocks (e.g., Bedrock, OpenSearch, Lambda, ECS/EKS) and secure enterprise deployments.

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.
