Job summary

Black Duck Software, Inc. is seeking a Principal Software Engineer for Agentic Integrations in Calgary. The role focuses on architecting production-grade, multi-agent workflows that connect SAST, SCA, and DAST into developers' toolchains, from IDEs to CI/CD and PRs.

You will lead technical direction and design, not just coding. You will drive MCP-based integrations, prototype new capabilities, and mentor peers while collaborating with Product and AI teams on a broader agentic strategy.

Qualifications

• Hands-on experience building agentic AI systems and multi-agent orchestration.
• Experience with MCP servers or plugin architectures in AI/IDE/CI workflows.
• 2+ years applying LLMs in production with real examples.
• Strong API and systems design skills for integrations and SDKs.
• Experience with CI/CD, Git workflows, and modern developer tooling.
• Initiative-driven, able to own projects end-to-end with minimal oversight.
• Excellent cross-functional communication across product, AI, and platform teams.

Responsibilities

• Own the big-picture architecture for agentic integrations across IDEs, CI/CD, and PR workflows.
• Identify opportunities and prototype new capabilities for agentic developer workflows.
• Design and implement agentic workflows, MCP tooling, and APIs for SAST/SCA/DAST products.
• Advance the Black Duck MCP Gateway and expand its surface area to AI agents and IDEs.
• Evolve agentic capabilities like AI fix recommendations and remediation guidance.
• Mentor engineers on system design and modern integration patterns.

Principal Software Engineer, Agentic Integrations

Location: Calgary, Alberta

Black Duck Software, Inc. helps organizations build secure, high-quality software, minimizing risks while maximizing speed and productivity. Black Duck, a recognized pioneer in application security, provides SAST, SCA, and DAST solutions that enable teams to quickly find and fix vulnerabilities and defects in proprietary code, open source components, and application behavior. With a combination of industry‑leading tools, services, and expertise, only Black Duck helps organizations maximize security and quality in DevSecOps and throughout the software development life cycle.

Role Overview

The Integrations team is looking for a Principal Software Engineer who can architect — not just implement — the agentic workflows that connect Black Duck's application security products (SAST, SCA, and DAST) directly into the developer's agentic workflow. This role is less about general programming depth and more about the hands‑on experience needed to design and harden production‑grade AI agent systems — multi‑agent orchestration, tool use, and MCP‑based integrations — that AI coding agents, IDEs, and orchestration frameworks can consume natively, extending work already underway on projects like the Black Duck MCP Gateway and SAST AI Fix Recommendation.

This is a hands‑on, senior technical role built for someone who takes initiative. We're looking for an engineer who doesn’t wait to be told what to build — who spots gaps in how our products show up in the agentic developer workflow, proposes a direction, and drives it to production. You'll be setting the architecture and technical direction — not just executing against a spec — for how Black Duck shows up inside the tools developers already use — from IDEs to CI/CD to PR workflows — while partnering closely with Product and Applied AI teams shaping the company's broader agentic strategy.

Key Responsibilities

• Own the "big picture" solution architecture for the integrations team — designing and hardening how agentic workflows, MCP surfaces, and multi‑agent orchestration patterns (task decomposition, tool use, agent hand‑off, frameworks such as Pydantic AI, LangChain, and LangGraph) fit together as a coherent system across IDEs, CI/CD, and pull request workflows. This is the core capability the role exists to fill, more so than general programming depth on its own.
• Identify new opportunities to bring Black Duck's capabilities into agentic developer and CI workflows, and take the initiative to prototype, pitch, and build them — this role is as much about proposing what we should build next as executing on what's already defined.
• Design, build, and implement agentic workflows and integrations — spanning agents, skills, MCP‑based tooling, and APIs — that bring Black Duck's AppSec products (SAST, SCA, DAST) into developer tooling, with strong attention to governance, permissions, and auditability.
• Own the technical direction and continued development of the Black Duck MCP Gateway, expanding the surface area of tools and capabilities it exposes to AI agents and IDEs.
• Contribute and evolve existing agentic capabilities such as SAST AI Fix Recommendation, improving remediation guidance and automated fix generation for developers.
• Mentor engineers on agentic system design and modern integration patterns.

Required Qualifications

• Hands‑on experience building agentic AI systems — multi‑agent orchestration, tool use, task decomposition (e.g., LangChain, PydanticAI, LangGraph, or equivalent).
• Experience building or integrating Model Context Protocol (MCP) servers, or comparable plugin/tool architectures in AI assistants, IDEs, and CI/CD workflows.
• 2+ years hands‑on experience applying LLMs into production workflows — prompt engineering, RAG pipelines, API‑based model integration, agent eval frameworks — with real examples, not just prototypes.
• Strong API and systems design skills — experience shipping integrations, SDKs, reusable connectors, or canonical models consumed across systems of record and by external developers.
• Experience with CI/CD, Git workflows, and modern developer tooling.
• A demonstrated track record of taking initiative and owning technical projects end‑to‑end — identifying opportunities, proposing solutions, and driving delivery from design through production with minimal oversight.
• Strong cross‑functional communication skills — comfortable working across Product, Applied AI, and platform engineering.
• Broad, well‑rounded software engineering background (8+ years) — Python, TypeScript/JavaScript, Go, APIs, distributed systems, and modern SCMs (GitLab, GitHub, Bitbucket, Azure).

Preferred (Nice to Have)

• Experience in Application Security (SAST, SCA, DAST, ASPM) or DevSecOps tooling.
• Experience with AI‑assisted development tools (GitHub Copilot, Claude Code, Cursor, or similar).
• Deep technical depth in LLM integration — vector databases/retrieval pipelines (Pinecone, Weaviate, ChromaDB, Qdrant, pgvector), function calling/tool use, and structured output parsing.
• Experience publishing and maintaining developer‑facing packages (npm, PyPI, etc.).
