The Position
We're looking to hire a Principal Agentic Engineer to join our team. This is a high-impact, client-facing role designed for a "plus-plus" version of a developer, someone who doesn't just build, but defines the architecture of how global enterprises adopt agentic workflows.

  • Successful completion of a four-year college degree is required.
  • Proven experience as a Solution Architect or Principal Engineer, with the ability to assess current engineering states and define roadmaps for implementing agentic solutions.
  • Deep fluency in Agentic Tooling like Claude Code, Cursor, Codex, or GitHub Copilot, specifically within agentic workflows that coordinate implementation across large, multi-file systems.
  • Ability to engage with engineering leadership (CTOs, VPs of Engineering) to defend architectural decisions, consult on industry best practices, and measure ROI/Developer Productivity (Cycle Time, Lead Time).
  • Experience designing development processes where AI systems generate the majority of implementation code, while maintaining rigorous human-in-the-loop validation.
  • Strong skills in structuring codebases and specifications to produce reliable, context-efficient AI output.
  • Exceptional soft skills; ability to walk clients through complex proposals and represent the FullStack team with confidence.
  • Forensic attention to detail.
  • A positive mindset and a can-do attitude.
  • Experience working on Agile / Scrum teams.
  • Meaningful experience working on large, complex systems.
  • Ability to take extreme ownership of your work. Every day is a challenge to ensure you are performing to the expectations you and your team have agreed upon.
  • Ability to identify with the goals of FullStack's clients, and dedicate yourself to delivering on the commitments you and your team make to them.
  • Ability to consistently work 40 hours per week.

What We Offer
  • Competitive Salary.
  • Paid Time Off (vacation, sick leave. parental leave, and holidays).
  • 100% remote work.
  • The ability to work with leading startups and Fortune 500 companies.
  • Health, dental, and vision insurance.
  • 401(k) w/ 4% match.
  • Ample opportunity for career advancement.
  • Continuing education opportunities.
