Role Overview We’re seeking a

Senior Data / ML / AI Engineer

to architect and build the intelligence layer of our autonomous sales platform. This role is responsible for designing, implementing, and optimizing the ML, LLM, scoring, retrieval, and agent-based systems that power live customer interactions and real business outcomes.

You will work closely with technology leadership to convert AI concepts into scalable, production-grade systems — including RAG pipelines, reinforcement-learning-based decision systems, vectorized knowledge bases, custom LLM deployments, real-time streaming inference, and multi-tenant data pipelines.

If you are a senior engineer who can bridge ML science, distributed systems, and pragmatic productionization, this role will put you at the core of a first-of-its-kind AI-native platform.

Key Responsibilities LLM, RAG & Agent Systems

Design, develop, and optimize

RAG pipelines

with high-performance vector databases (Milvus, Zilliz, Pinecone, Weaviate).

Build

scoring, ranking, and predictive models

that drive real-time decision-making for sales and customer interactions.

Develop and refine

agent-driven architectures , including tool calling, memory management, and multi-step reasoning flows.

Deploy, fine‑tune, and optimize

custom LLMs , ensuring cost efficiency and performance at scale.

Enrich internal knowledge bases and embeddings using advanced ML techniques.

Machine Learning Engineering & Data Infrastructure

Build large-scale

data ingestion, transformation, and real-time streaming

pipelines for model training and inference.

Implement

reinforcement learning systems

that improve agent behaviors over time.

Own ML model lifecycle: development, evaluation, deployment, optimization, and monitoring.

Drive

LLM cost optimization , including token efficiency, caching, and inference routing.

Production Systems & Platform Integration

Architect and maintain

microservices

exposing ML/LLM capabilities through secure APIs.

Work with real-time systems:

voice, streaming, WebSockets , and other live interaction pipelines.

Ensure multi-tenant data isolation, configuration management, and performance scaling.

Collaborate cross‑functionally to define data contracts, agent flows, and platform intelligence requirements.

Required Skills

7+ years of ML Engineering experience

in production environments.

Expert-level

Python

for ML workflows, backend services, and data pipelines.

Strong experience with

vector databases

(Milvus, Zilliz, Pinecone, Weaviate).

Experience building and deploying

reinforcement learning systems .

Deep hands‑on experience with

LLMs, RAG, prompting, scoring models, and tool calling .

Experience with

LangChain / LangGraph

and modern LLM orchestration frameworks.

Proven ability to design and optimize

large‑scale ML data pipelines .

Production experience with

real-time systems

(voice, streaming, WebSockets).

Proficiency with

SQL and NoSQL

databases.

Strong understanding of

microservices architecture , distributed systems, and event‑driven workflows.

Proficiency with

Docker & Kubernetes

for deployment and orchestration.

Experience delivering

custom LLM deployments

in production.

Ability to collaborate with engineering leadership and turn concepts into shipped capabilities.

Nice to Have

Experience with

streaming data systems

(Kafka, Kinesis, Pulsar).

Experience with

model monitoring, drift detection, and automated evaluation

Background with

AWS ML stack

(SageMaker, Bedrock, EKS, Lambda).

Experience with model compression, quantization, or accelerated inference.

Familiarity with CRM data patterns or real-time ingestion (Salesforce, HubSpot, Zoho).
