Lead AI Data Scientist

Job Description

Role: Lead AI Data Scientist

Company: Arch Systems

Client: Federal

Engineering Agentic Intelligence Across Federal Missions

Location: Remote / Hybrid

Type: Full-time Contract W2 or 1099

Level: Senior / Principal

About the Role

Arch Systems is seeking a Lead AI Data Scientist to serve as both a technical architect and delivery leader across its growing portfolio of AI/ML-driven federal digital modernization projects. This role is ideal for a technologist who thrives at the frontier of Agentic AI, cognitive architectures, and Model Context Protocols (MCPs)—not in theory, but in mission-aligned production systems that drive real-world impact for agencies such as HHS, DHS, and NIH.

You’ll lead the delivery of agent-based solutions, develop instruction-fidelity frameworks, deploy secure AI pipelines, and shape model governance across multiple contracts—bringing together science, systems, and scale.

Key Responsibilities

Lead the design, development, and deployment of Agentic AI solutions and LLM-based agents for data orchestration, workflow automation, and mission-critical analysis

Build and implement Model Context Protocols (MCPs) that govern instruction flow, semantic memory, task chaining, and real-time signal processing across federated environments

Deliver federal project solutions aligned with security, compliance, and auditability (FedRAMP, FISMA, HIPAA, NIST 800-53)

Translate requirements into AI/ML pipelines optimized for cloud-native delivery (AWS, Azure, containerized environments)

Apply advanced machine learning techniques including prompt engineering, fine-tuning, retrieval-augmented generation (RAG), and RLHF

Lead and mentor a cross-functional delivery team (data scientists, MLOps engineers, solution architects) across concurrent federal AI projects

Partner with program managers and clients to align deliverables, define roadmaps, and contribute to proposals and innovation white papers

Tech Stack & Methodologies

LLMs & Agent Frameworks: GPT-4, Claude, Mistral, LLaMA, T5, LangChain, CrewAI, AutoGen, ReAct, BabyAGI

MCP Engineering: Instruction protocols, memory embeddings, semantic task managers, autonomous agent flows

Cloud & Deployment: AWS Sagemaker, Azure ML, Docker, Kubernetes, Terraform, GitHub Actions

Data Pipeline Stack: Python, Spark, Snowflake, Delta Lake, dbt, Airflow

MLOps & Model Lifecycle: MLflow, Weights & Biases, Kubeflow, Model Registry, Feature Stores

Security Compliance: FedRAMP Moderate, FISMA, HIPAA, Section 508, CUI

Delivery Context: Agile delivery teams, DevSecOps pipelines, multi-vendor government engagements

Key Qualifications

Ph.D. or Master’s in Computer Science, Data Science, AI, or related field

6–10+ years of experience in machine learning, data science, or AI R&D

Proven track record with:

Transformers & LLMs: HuggingFace, LangChain, OpenAI, T5, BERT, GPT, Mistral

Deep Learning: PyTorch, TensorFlow, Keras

MLOps tools: MLflow, Kubeflow, Weights & Biases

Cloud Platforms: AWS Sagemaker, Azure ML, GCP Vertex AI

Modern Data Stack: Spark, Snowflake, Delta Lake, Airflow, dbt, etc.

Proficient in Python, SQL, Docker, Kubernetes, and RESTful APIs

Knowledge of FedRAMP, FISMA, NIST 800-53, and HIPAA compliance preferred

Excellent communication skills with the ability to influence, mentor, and align cross-functional teams
