AI Engineer / Senior Engineer

About Doceree

Doceree is the world's only AI-powered Operating System for healthcare marketing. We aim to be a catalyst for change, improving healthcare by enabling more meaningful interactions with HCPs. Our patented AI brings deeper context to every HCP touchpoint-understanding who HCPs are, what they're exploring, how they engage, and when they make decisions, all in a privacy-compliant way. With this enriched context, every message becomes clearer, more relevant, and more likely to drive better healthcare outcomes. In our journey of 5 years, we have earned four patents for innovation and even won a Silver award at the Cannes Lions, one of the world's top advertising honors. Over the years, we've also had the opportunity to work with 115+ pharma companies and collaborate with 30+ media publications, 150+ EHR platforms, 2,000+ publisher networks, and 35+ hospitals and health systems. Our ecosystem connects us with more than 6 million verified doctors worldwide. Today, Doceree operates across 25+ countries, with teams based in New Jersey, London, and India.

Technology can connect the fragmented healthcare ecosystem to deliver information when it is most needed to improve patients' outcomes. We are expanding our footprints across the globe and enhancing our services, offering, and developing new products and solutions to address the unmet needs of industry.

Purpose of the Job

Doceree is building the first proactive intelligence layer for pharma brand teams - an agentic AI system that turns clinical intent signals, campaign data, and market context into a daily brief that drives a decision in under five minutes. We are hiring AI Engineers to build the systems behind that surface.

You will design and ship production AI systems - LLM-powered pipelines, agentic workflows, retrieval over heterogeneous healthcare data, evaluation harnesses, and the orchestration layer that sits between our signal foundation and the brand manager's morning brief. You'll work closely with data scientists, product, and platform engineering to take prototypes from a notebook to something a brand team relies on everyday.

You'll thrive here if you enjoy living at the seam between LLMs, traditional ML, and well-engineered backend systems - and if you care about making AI useful, reliable, and measurably better in a regulated, real-world domain.

Key Responsibilities

Design, build, and ship production-grade LLM and agentic AI systems powering anomaly detection, contextual synthesis, next-best-action recommendations, and one-click activation across the Daily Command product surface
Build robust retrieval-augmented generation (RAG) pipelines over Doceree's clinical intent signals, campaign data, market data, and partner data - including chunking, embedding, indexing, hybrid retrieval, reranking, and grounding strategies
Implement agent orchestration patterns (tool use, planning, multi-step reasoning, structured outputs, guardrails) using modern frameworks (e.g., LangGraph, LlamaIndex, custom orchestration) and own the latency, cost, and reliability of those agents end-to-end
Build evaluation and observability for AI features - offline eval sets, golden datasets, LLM-as-judge harnesses, regression tests, online metrics, prompt/version tracking, and trace inspection
Engineer prompts, system instructions, and tool interfaces as first-class artifacts - versioned, tested, and tied to measurable business outcomes (lift, NBRx correlation, decision time, action acceptance rate)
Integrate and benchmark multiple model providers (OpenAI, Anthropic, Google, open-source via vLLM/TGI), and make pragmatic build-vs-buy and model-routing decisions based on quality, latency, and unit economics
Partner with data scientists to productionize ML models (classification, ranking, recommendation, embedding, forecasting) - wrapping them in services, pipelines, and APIs that downstream agents and product surfaces can consume
Own scalable, cloud-native deployment of AI services on AWS, with strong MLOps/LLMOps hygiene: CI/CD for models and prompts, feature/vector stores, monitoring, drift detection, cost guardrails, and safe rollout
Implement safety, privacy, and compliance controls appropriate for healthcare/HCP data - PII/PHI handling, prompt injection defenses, output validation, auditability, and human-in-the-loop where it matters
Collaborate with product and design to translate fuzzy user problems into well-scoped AI subsystems, then prototype quickly, evaluate honestly, and harden the winner
Stay current with advances in LLMs, agents, retrieval, evaluation, and inference infrastructure, and bring back what's genuinely useful

Qualifications - Experience, Skills & Education

B.Tech / M.Tech / Ph.D. in Computer Science, Information Technology, Statistics, or related quantitative discipline from a Tier 1/2 institution
2-8 years of experience building and shipping AI/ML systems in production, with at least 2+ years focused on LLM-based or agentic AI applications (RAG, tool-using agents, copilots, structured generation, evaluation)
Strong programming fundamentals in Python, with solid software engineering practices (typing, testing, code review, modular design, performance awareness). Comfortable in SQL and working with cloud-native data systems
Hands-on experience with one or more LLM/agent frameworks (LangChain/LangGraph, LlamaIndex, Haystack, Semantic Kernel, or well-reasoned custom stacks) and vector databases (pgvector, Pinecone, Weaviate, OpenSearch, FAISS, etc.)
Practical experience with prompt engineering, structured outputs (JSON schemas / function calling), tool use, and evaluation - including building your own eval harnesses rather than relying solely on vendor dashboards
Working knowledge of classical ML/DL libraries (scikit-learn, PyTorch, TensorFlow, Hugging Face Transformers, SpaCy, NumPy, Pandas) and when not to reach for an LLM
Experience deploying services on AWS (Lambda, ECS/EKS, SageMaker, Bedrock) and familiarity with MLOps/LLMOps tooling (MLflow, Weights & Biases, LangSmith, Langfuse, Arize, or equivalents)
Demonstrated ability to operate on noisy, incomplete, and sensitive real-world data, and to design systems that fail safely, observably, and recoverably
Strong product instincts - you can push back on a half-formed requirement, scope an MVP, and know when "good enough to ship and learn" beats "perfect on a benchmark"
Excellent written and verbal communication; able to explain agent behavior, eval results, and trade-offs to non-technical stakeholders, and to write design docs the rest of the team will actually read

Preferred Qualifications

Experience building multi-agent or workflow-based AI systems (planner/executor patterns, critic/verifier loops, long-running agents with state)
Familiarity with inference optimization - quantization, batching, KV cache reuse, speculative decoding, serving with vLLM/TGI/Triton, or building latency/cost-aware model routers
Solid grounding in the math behind ML and LLMs - linear algebra, probability, statistics, and a working understanding of how transformers and embeddings actually behave
Experience with healthcare, life sciences, or programmatic advertising data - claims, Rx, EHR-derived signals, HCP identity, campaign telemetry, attribution. Awareness of HIPAA / GDPR / DPDP considerations is a plus
Familiarity with containerization and orchestration (Docker, Kubernetes), event/streaming systems (Kafka, Kinesis), and big-data tooling (Spark, Aerospike, DuckDB)
Open-source contributions, public technical writing, or a portfolio of shipped AI features you can walk us through end-to-end
