Staff Engineer, AI Developer Experience

GitGuardian is a global cybersecurity scale-up. The company is based in Paris, New-York City, Boston.

Among our early investors who saw our market value proposition, are the co-founder of GitHub, Scott Chacon, along with Solomon Hykes, Docker's co-founder. American and European top-tier VC firms have also invested in GitGuardian who raised its series C early 2026.

GitGuardian helps enterprises close credential-based breach paths. It finds secrets wherever they live, prioritizes remediation based on rich context, and prevents new exposure across code, systems, and AI. The GitGuardian platform is already used by more than 600K developers worldwide and by 50 of the fortune 500!

We are building the AI operating model that empower 70+ engineers to ship faster without losing control of quality.

You will join our Developer Efficiency team and take ownership of one of the most ambitious projects we have in the company: moving our engineering processes and product development toward dark factory maturity, where AI handles the routine and humans focus on what requires judgment.

The objective is to design AI agents that code our products, build the specs-to-production pipeline that reduces lead time from idea to merge-ready code, and co-own the AI toolchain roadmap alongside our other Staff Engineers and CTO.

You will have a pragmatic view – based on your product-oriented mindset – on how this should be built. You will have the liberty and authority to define the approach and drive it forward. The tools you ship will be used every day by 70 engineers. You will spend your first weeks as part of feature teams to understand their actual constraints, then design and ship systems that make their daily work meaningfully better.

Your main responsibilities will be:

Design and ship AI agent workflows

• Get an overview of our ongoing initiatives, challenge and improve them

• Design and deploy background AI agents that autonomously handle specific engineering work: bug triage, diagnostics, patch suggestions, and code review

• Define prescriptive agent workflows and skills that teams can adopt and extend

• Improve our AI review pipeline

Own the specs-to-production pipeline

• Implement automated workflows from design/spec to merge-ready code

• Build faster feedback loops through better test generation and AI-assisted validation

• Consolidate individual and team-level AI practices into a pragmatic, enforced approach: move from an artisanal one (Cursor + Claude Code per engineer) to a systematic one

Co-own the AI toolchain roadmap

• Work directly with our Staff Engineers and CTO to define what gets built, in what order, and why

• Join feature teams on a regular basis to keep the roadmap grounded in real constraints

If you think you match at least 70% of these criteria, please apply!

Here's what we consider essential for success in this role:

• Founder or early-stage operator background: you have built and shipped an AI product, talked directly to users, and dealt with real constraints. You know what it's like to ship fast, with no safety net. If you founded a company (failed or not) and spent time in a startup accelerator, that background makes you stand out here.

• Product mindset with technical depth: before shipping a feature, you ask who uses this and why. You treat internal engineers as customers and design solutions for their actual workflows.

• Hands-on AI/LLM experience: you have developed with AI agents, LLM APIs (Claude, OpenAI, etc.), or agentic frameworks in production.

• 5+ years of technical experience, Python environments (our stack is Python + Django, TypeScript, Rust).

• Influence without authority: you move people through ideas, prototypes, and clear thinking. You manage to build your solutions with a great balance between the vision of the Company and the needs of the teams.

• Structured, autonomous execution: you can research a problem space, propose an opinionated solution, document it clearly, and drive it to completion with minimal oversight.

• Fluency in English, written and spoken.

The following skills would strengthen your application but aren't required:

• Background in platform engineering or developer tooling

• Familiarity with CI/CD optimization

• Basic knowledge of DORA metrics or DX Framework

• Fluency in French
