Senior Specialist, AI Engineer

Do meaningful work with us. Every day.

At Amplify Health, we’re looking for individuals with ambition, resilience and passion for healthcare, insurance, wellness  and digital technology. As a fast-growing business with the ambition of making people and communities across Asia healthier, we have exciting career opportunities available to help us achieve our vision.

The Senior AI Engineer (Specialist) plays a pivotal role in designing, developing, and deploying GenAI/LLM, NLP and agentic AI solutions that deliver actionable insights across healthcare, insurance, and wellness domains. This individual collaborates with cross-functional teams, including data engineers, actuaries, clinicians, and product managers, to transform structured + unstructured healthcare data into LLM-enabled products (RAG copilots, summarization, extraction, triage, coding/abstraction, search, and agent workflows) with measurable reliability and safety.
The role requires a blend of hands-on technical expertise, curiosity, problem solving and business acumen. The Senior AI Engineer is responsible for end-to-end delivery for AI workstreams from scoping to deployment/ monitoring; leads feature engineering strategy; mentors juniors and performs code reviews on top of being hands on. This role emphasizes engineering excellence: API/service design, testing, observability, release governance, and cost/latency optimization for LLM systems.
The ideal candidate thrives in a fast-paced, agile environment and is passionate about leveraging data to solve real-world healthcare challenges.

Responsibilities

1) NLP/LLM Solution Architecture & Product Delivery

• Define what data is needed (first-/third-party, events, text, image, claims/transactions, IoT), data quality thresholds, and labelling strategy.
• Define north-star metrics (online and offline) and decision boundaries; craft counterfactuals and baselines (e.g., business-as-usual) to quantify impact. Connect model metrics to business outcomes.
• Own end-to-end delivery: design → build → test → deploy → monitor → iterate.
• Define system requirements including SLAs/SLOs, latency budgets, accuracy targets, cost ceilings, and safety constraints.
• Write and maintain AI System Design Specs (problem statement, users, decision loop, constraints, risk posture, evaluation plan, rollout strategy, and guardrails).

2) LLM/NLP Development (Hands-on Build)

• Build RAG pipelines: corpus ingestion, chunking strategies, embedding selection, indexing, retrieval/reranking, grounding, citations, and fallback strategies.
• Develop prompt/tool schemas and agent designs: function calling, tool routing, memory patterns, and multi-step workflows.
• Apply modern NLP methods where appropriate: token classification, sequence labeling, semantic similarity, topic modeling, and hybrid IR (BM25 + dense retrieval).
• Ensure correctness through unit/integration tests, robust error handling, and deterministic behavior where needed.
• AI/ ML Accelerators development:
  - Build and maintain reusable ML accelerators (Cookiecutter, Feature Engineering Toolkit, AutoML , Unified Evaluation Harness, Observability Blueprints, Responsible AI Pack etc) that standardize feature engineering, model training, and evaluation across tasks.

3) Evaluation, Quality, and Reliability (LLMOps)

• Build and maintain evaluation harnesses:
  - Offline test sets, golden datasets, and regression suites
  - LLM-as-judge where appropriate (with controls)
  - Human-in-the-loop review loops for high-risk workflows
• Define and track quality metrics: groundedness, faithfulness, toxicity/safety, extraction accuracy, retrieval precision/recall, and task success rates.
• Implement guardrails: policy filters, PHI/PII handling, prompt injection defenses, output constraints, and safe-completion behaviors.

4) Production Engineering, MLOps & Observability

• Productionize services using containerization and orchestration (e.g., Docker, Kubernetes) and CI/CD pipelines.
• Implement observability: structured logging, traces, prompt/version tracking, vector DB metrics, and cost monitoring.
• Monitor performance and drift signals; define retraining/re-indexing/re-prompting strategies and release governance.
• Optimize for performance and cost: caching, batching, streaming, quantization where relevant, and efficient retrieval.

5) Collaboration & Stakeholder Engagement

• Partner with cross-functional teams—including actuaries, clinicians, engineers, and product managers—to align technical solutions with strategic objectives.
• Facilitate technical workshops and presentations to ensure clarity and buy-in across diverse audiences.
• Act as a subject matter expert on analytics, data science methodologies and best practices.

6) Governance & Compliance

• Ensure adherence to data privacy regulations and implement security best practices across all data science workflows.
• Advocate for responsible AI by incorporating fairness, explainability, and bias detection into model development.
• Maintain comprehensive audit trails and documentation for regulatory compliance and internal governance.
