## About the Role

* 8+ years of software engineering experience, with a track record of shipping and operating full-stack production systems;
 * Deep hands-on expertise in React with TypeScript (Next.js or a similar framework) and Node.js/TypeScript or Python back ends, including API design, authentication (OAuth/OIDC) and containerized deployment on Kubernetes
 * Strong data modeling and database skills, especially PostgreSQL: schema design for versioned and hierarchical metadata, indexing and query optimization, partitioning, caching, and knowing when to use document, graph or vector store
 * Shipped at least one production feature built on LLMs or AI agents (not only used AI coding assistants), and uses agentic development tools as a core part of daily engineering work
 * Thrives in a startup-style environment: comfortable with ambiguity, ships MVPs quickly, iterates on feedback and owns outcomes end to end

Desirable Requirements

 * Bachelor's degree in Computer Science, Engineering or equivalent experience
 * Experience building developer platforms, SDLC/DevOps tooling or governance and audit systems, including GitHub/GitHub Enterprise API integrations, Redis, pgvector, event sourcing or knowledge graphs (e.g. Neo4j)
 * Experience with LLM evaluation and agent frameworks (e.g. LangGraph, OpenAI Agents SDK), MCP, Playwright end-to-end testing, Red Hat OpenShift, or contributions to open-source AI projects

## Description

The Agentic Development Lifecycle (ADLC) Portal is the central platform our engineering organization uses to deliver software with AI agents as first-class team members. Engineers, architects and product managers use it to author and approve specifications, launch and monitor agent-driven implementation pipelines, enforce quality and governance gates, and trace every change from requirement to production with a full audit trail and delivery metrics. We are a small, AI-native team operating like a startup inside Dell: high autonomy, weekly shipping, and humans and AI agents sharing the delivery work every day. We don't just use AI tools; we build the platform that governs how AI builds software.

Join us to do the best work of your career and make a profound impact as a Software Principal Engineer on our AI Governance Engineering team in Hopkinton, Massachusetts. This is an onsite role.

What you'll achieve

As the senior hands-on engineer on the ADLC Portal, you will design and ship major subsystems end to end: front end, back-end services, and the data layer that stores specifications, artifacts, agent runs and their lineage. You will spend most of your time building (70%+), working alongside AI agents as part of your daily workflow, and setting the technical bar for the team.

Responsibilities

You will:

 * Build and own major portal capabilities across the full stack, including React/TypeScript user experiences on Next.js and Node.js/TypeScript (or Python) services and APIs, from design through production operations
 * Design the data layer for versioned specifications, agent-run records, lineage and audit trails, choosing the right mix of relational (PostgreSQL), document, graph and vector storage and keeping queries fast and cost-efficient as data grows
 * Integrate AI agents and LLMs into the product: tool calling, agent orchestration, streaming agent output, retrieval (RAG) and MCP integrations, with evaluations and guardrails that make agent output trustworthy
 * Work AI-native every day: write specs that agents implement, review and correct agent-generated code and tests, and continuously improve how the team delivers with agents
 * Raise the engineering bar through code and design reviews, test-driven development, observability, CI/CD on Kubernetes, and mentoring engineers on the team, * Front end: React 19 and TypeScript on Next.js 16 (App Router, Server Components, Server Actions), Tailwind CSS, Chart.js.
 * Back end: Node.js / TypeScript services and APIs with Zod schema validation, server-sent events for streaming agent output; Python (e.g. FastAPI) services
 * Data: PostgreSQL, plus caching and file-backed state stores, with a roadmap toward Redis, vector search (e.g. pgvector) and graph-based lineage
 * AI and agents: OpenAI-compatible LLM gateway, agent loops with tool calling, AI coding agents (e.g. Claude Code, Devin, Copilot) and MCP integrations
 * Integrations and identity: GitHub Enterprise REST and GraphQL APIs (Octokit, GitHub Apps), OAuth/OIDC single sign-on (NextAuth, Okta)
 * Quality and delivery: Vitest, React Testing Library, Playwright with accessibility checks, ESLint, test-driven development, GitHub Actions CI/CD, Docker, Kubernetes / Red Hat OpenShift with autoscaling
