We are currently looking to hire AI Engineer.
This is an exciting opportunity to expand your skill set, achieve job satisfaction and work-life balance. More details as below.
Job Description
This role sits within organization AI Central's (AIC) Forward Deployed Engineering (FDE) model — the combined capability that takes AI solutions from proof-of-concept through to hardened production systems. As AI Engineer, you design and run rapid experiments on Gen AI models, prompts, and retrieval strategies to give the squad fast, evidence-based answers on model performance — operating primarily within fast-moving FDE engagements (POC/POV, pilot deployments).
What will you do:
1. Experimentation & Evaluation - Understand the business problem, POC objectives, and evaluation metrics. - Design experiments to test different model configurations, prompts, or retrieval strategies. - Analyse Gen AI outputs for quality, accuracy, and alignment with requirements; identify common failure modes (hallucination, bias, irrelevant answers, factual errors). - Support SMEs in defining ground truth benchmarks for evaluation.
2. Data Preparation & Pipelines - Profile and clean sample datasets for experimentation (lightweight data prep). - Build and test simple pipelines for data ingestion, prompt construction, and output evaluation.
3. Gen AI & Agentic Techniques - Work with foundation models via AWS Bedrock, Google Vertex AI, or Azure AI Foundry depending on engagement cloud posture. - Apply working knowledge of China-origin models (DeepSeek, Qwen, GLM) as increasingly relevant, cost-effective alternatives. - Apply agentic orchestration frameworks such as AWS Strands, LangGraph, or equivalent, for designing and testing multi-step agent workflows. - Apply prompt strategies, prompt engineering patterns, and RAG design (chunking, embeddings, retrieval evaluation); support ingesting/vectorising content to knowledge bases. - Provide insights and recommendations to improve model performance in quick iterations, including fine-tuning approaches where applicable.
4. FDE & Development/Maintenance Coverage - During FDE engagements: rapidly test candidate models, prompts, and retrieval strategies, giving the team fast, evidence-based go/no-go signals. - During system development & maintenance engagements: support ongoing model/prompt tuning and monitoring as applications move toward production.
5. Collaboration - Collaborate with developers on integrating models into the POC workflow, and work closely with PM, devs, and SMEs to refine data and prompts. - Partner with the Data Scientist on evaluation methodology where classical statistical baselines are in play, and with the AI/LLM Specialist when an engagement moves toward production-grade evaluation. - Document experiments briefly but clearly (hypothesis → result → conclusion). Role Levels We Are Hiring For We are hiring at two levels for this role. All responsibilities above apply to both; the distinction is in scope of ownership, years of experience, and seniority of judgement expected. Senior AI Engineer - 6+ years of hands-on experience, including prior ownership of experimentation strategy for complex or ambiguous problem statements. Sets the experimentation approach across multiple engagements and mentors junior AI Engineers. - Advises PMs and stakeholders directly on feasibility and experimentation trade-offs; represents technical experimentation findings in client conversations.
Qualifications
The ideal candidate should possess: - 4+ years hands-on experience in AI/ML or Gen AI engineering (see Role Levels for the split between AI Engineer and Senior AI Engineer). - Understanding of Gen AI concepts (tokenization, embeddings, RAG, prompting, evaluation). - Familiar with at least one major cloud AI service (AWS Bedrock, Google Vertex AI, or Azure AI Foundry); working knowledge of others a plus. - Working knowledge of the China AI model landscape (DeepSeek, Qwen, GLM) a strong plus. - Familiarity with agentic orchestration frameworks (AWS Strands, LangGraph, or equivalent), for designing and testing multi-step agent workflows. - Ability to do rapid experimentation rather than perfect models. - Basic proficiency in Python and Gen AI tools (e.g., model SDKs, vector DBs). - Analytical mindset: can quantify subjective output (accuracy, relevance, readability). - Good data wrangling skills to prepare small datasets quickly. Preferred Qualifications - Generative AI Leader or Machine Learning Engineer certification, or equivalent. - Exposure to LLMOps practices (model monitoring, versioning) for production transition. - Familiarity with model fine-tuning techniques. - Exposure to regulated government cloud environments. Tech Stack (Illustrative) - Languages: Python - LLM Runtime: AWS Bedrock, Google Vertex AI, Azure AI Foundry; DeepSeek/Qwen/GLM (China stack) - Agentic Frameworks: AWS Strands, LangGraph - Data & Eval: Model SDKs, vector DBs, pandas/Jupyter-style tooling for experimentation
