Generative & Agentic AI Engineer

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 areaccurate, explainable, and aligned with intelligence use cases.

Agentic AI & Workflow Automation

You willassistin 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.

• Assistin 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 withLLMs and/or SLMs, including prompting, inference, or fine-tuning.

• Experience building or contributing toRAG pipelines, embeddings, or retrieval systems.

• Familiarity withagent-based systemsor workflow automation (academic, professional, or open-source).

• Strong programming skills inPython; 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 tointelligence, 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, ora relatedtechnical fieldrequired.
Advanced degree is a plus but notrequired.
