Job Title: Software Development Engineer - Agentic AI
Role Overview: Join our innovative team at Trellix, where you'll lead the design and development of a cutting-edge generative AI platform powering advanced AI capabilities across the entire Trellix security portfolio. This isn't prototype work. You'll be building and operating production agentic systems deployed in federal environments, enabling autonomous SOC workflows, multi-agent orchestration, and seamless AI integration across our security products. We're looking for a highly skilled Software Development Engineer with a passion for building robust, scalable, and secure AI solutions that operate at real-world scale.
This role is hybrid in nature with the Engineer able to commute into the Frico, TX office 3-4 days/week.
About the Role:
Design and Develop: Lead the design and development of our generative AI platform, driving core functionality, agentic workflows, and platform-level features from concept through production.
End-to-End Ownership: Take full ownership of features and functions, from initial design and development through rigorous testing, automation, and ongoing operational health.
Agent Workflow Development: Build, iterate on, and harden multi-agent pipelines, including tool use, inter-agent coordination, and autonomous decision workflows for security operations.
Deliver High-Quality Solutions: Ensure solutions are delivered on time, within budget, and to the highest quality standards, meeting project goals and customer commitments.
Ensure Resilience & Security: Proactively implement best practices to ensure applications are highly resilient, secure, and performant, with particular attention to the sensitivity of security operations data.
Observability & Telemetry: Design and implement instrumentation using OpenTelemetry, contribute to operational dashboards, and surface platform health and usage insights to engineering leadership and stakeholders.
Technical Analysis & Documentation: Analyze feature requirements and produce detailed design documentation, architectural decision records, and async-friendly technical specs.
Production Reliability & Incident Response: Own production issues end-to-end, including triage, root cause analysis, post-mortems, and SLA commitments, for a platform operating in high-stakes environments.
About You:
Experience: 5+ years of professional experience in Python application software development, with demonstrated experience building and operating production AI or platform systems.

AI/ML Knowledge:
Hands-on experience with Large Language Models (LLMs) in production
Langchain experience required, including building and operating stateful multi-agent workflows
Experience with prompt orchestration and chain composition
Familiarity with Agentic AI concepts and patterns (ReACT, chain-of-thought, tool use, Deep Agents)
Experience deploying and operating vLLM for self-hosted inference
Familiarity with MCP (Model Context Protocol) for agentic tool integration
Frameworks & Technologies:
FastAPI (preferred)
Node.js / TypeScript for tooling and API integration layers (preferred)
