ROLE SUMMARY 

As an Engineer on the Generative & Agentic AI team, you will play a hands-on role in building, deploying, and operating AI capabilities that power Babel Street’s intelligence applications. You will work closely with senior AI leaders, product teams, and engineers to implement generative and agentic AI solutions that support investigative, analytical, and operational workflows across the platform. 

This is an execution-focused role for an engineer with strong foundations in machine learning and generative AI who is excited to work on real-world, mission-driven applications. You will contribute directly to LLM and SLM pipelines, retrieval and grounding systems, agent workflows, and AI-enabled features—while learning how to deliver AI that is safe, reliable, cost-efficient, and production-ready. 

This is a hybrid role to be based out of either our Reston, VA/Washington DC office or our Somerville MA office.

ROLE FOCUS 

This role spans three practical execution areas: 

Generative AI & Model Development 

You will help implement and operate LLM- and SLM-based systems, contributing to prompt development, fine-tuning, evaluation, and inference optimization. You will support retrieval-augmented generation (RAG) pipelines, embeddings, and grounding techniques to ensure AI outputs are accurate, explainable, and aligned with intelligence use cases. 

Agentic AI & Workflow Automation 

You will assist in building and integrating agent-based workflows that automate analytical tasks, connect platform services, and support intelligence applications. This includes implementing agent logic, tool-use patterns, and basic orchestration under the guidance of senior engineers. 

AI Engineering & Production Delivery 

You will help productionize AI capabilities using modern AI SDLC tools and practices, contributing to evaluation, testing, telemetry, and guardrails that reduce hallucinations and ensure safe behavior. You will work within established governance frameworks to ensure AI features are measurable, reliable, and cost-aware. 

KEY RESPONSIBILITIES 

  • Implement and maintain LLM and SLM pipelines, including prompt engineering, inference, and evaluation. 
  • Support RAG pipelines, embeddings, and retrieval systems used in intelligence applications. 
  • Assist in building agent workflows that automate analytical or operational tasks. 
  • Write clean, maintainable code (Python or others) to support AI services and integrations. 
  • Contribute to AI evaluation, testing, and hallucination-mitigation techniques. 
  • Use AI-assisted development tools (e.g., Copilot, Cursor) to improve development velocity and quality. 
  • Collaborate with Product and Engineering teams to integrate AI capabilities into user-facing workflows. 
  • Follow established AI governance, safety, and cost-optimization practices. 

 

QUALIFICATIONS 

Required 

  • 5+ years of experience in software engineering, machine learning, or applied AI roles. 
  • Hands-on experience working with LLMs and/or SLMs, including prompting, inference, or fine-tuning. 
  • Experience building or contributing to RAG pipelines, embeddings, or retrieval systems. 
  • Familiarity with agent-based systems or workflow automation (academic, professional, or open-source). 
  • Strong programming skills in Python; experience with common libraries (PyTorch, TensorFlow, etc.). 
  • Solid foundation in machine learning concepts (training, evaluation, overfitting, metrics). 
  • Experience using or contributing to modern AI/ML tooling and workflows (ML pipelines, evaluation scripts, model serving). 
  • Ability to work in a collaborative, fast-moving, mission-driven environment. 

Preferred 

  • Experience applying AI to intelligence, investigative, analytical, or risk-related applications. 
  • Familiarity with vector databases, graph databases, or knowledge graphs. 

 

EDUCATION 

Bachelor’s degree in Computer Science, Engineering, Data Science, or a related technical field required. 
Advanced degree is a plus but not required.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
