About GitGuardian
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!

About Your Team And Your Mission
The Core Squad is responsible for the logical layer that all other GitGuardian teams build on top of. When a customer deploys our platform across thousands of developers, our code is what determines whether everything scales: authentication, permissions, provisioning, notifications, APIs, billing. None of this can break, and everything needs to operate at scale.

Our scope

  • Identity: SSO/SAML, MFA
  • Provisioning: SCIM, JIT
  • RBAC: Teams, roles, and access rights
  • Opening the platform: Public API, OAuth2, GitHub check runs, notifiers, and ticketing integrations (Slack, Jira, ServiceNow, Splunk, PagerDuty, MS Teams, webhooks)
  • Product trust and observability: Audit and activity logs, data source health checks, in-app analytics
  • Monetization: Billing and modular plan architecture

What you will work on

  • Complete the platformization journey. Migrate our existing customers to the platform without disrupting any alerting channels. Concretely: ensure notifier parity, redesign the notification core to reconcile synchronous and asynchronous delivery, build Slack threading and DMs, and enable customizable email templates.
  • Scale GitHub check runs. They block pull requests for most of our customers: GitHub API rate limits, database load spikes, dedicated Celery queues, and handling very large merge requests. Any incident here is immediately visible to customers.
  • Redesign our plan architecture so Product and Sales teams can assemble offers and activate modules without requiring Engineering intervention.
  • Open the platform externally: Build OAuth2, public APIs, and integrations with our customers’ ASPM ecosystems.
  • Evolve a large Django monolith: dependency inversion, typing improvements, progressive decomposition. This is a real architecture challenge, not cosmetic refactoring.
  • Rethink self-service onboarding, where a significant portion of new workspaces currently never reach their first value moment.
  • Build and improve health check systems for our integrations.

Your role day-to-day

You will code every day and own the end-to-end delivery of projects: scoping with the PM and designer, technical design, implementation, deployment, monitoring. You own what you ship, including in production.

Beyond your own delivery, you will help raise the engineering bar across the team: reviewing your peers’ code, mentoring more junior engineers, driving quality standards, and contributing to technical decisions when designs impact our broader platform.

The team currently consists of 3 senior engineers (backend, frontend, full-stack), 1 engineering manager, 1 product manager, and 1 designer.

About You
If you think you match at least 70% of these criteria, please apply!
Here's what we consider essential for success in this role:

  • 5+ years of experience in web development, with strong proficiency in Django (or another Python web framework such as FastAPI or Flask)
  • Experience building web applications, task orchestration, distributed systems, and managing large data flows
  • The ability to own a project or feature end-to-end: from scoping with Product and Design, to technical design, implementation, deployment, and monitoring
  • A dynamic and proactive mindset, always willing to support and help teammates
  • Strong written and verbal communication skills in both English and French, with the ability to move from high-level discussions to deep technical dives
  • Strong proficiency in AI-assisted development workflows

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

  • Significant experience working with a large monolithic codebase, along with knowledge of architecture best practices in this type of environment
  • An interest in refactoring and building reliable systems

The interview process

At GitGuardian, we are committed to building a diverse, equitable and inclusive workforce.
We will ask for your gender identity on the application page to help us understand the diversity of our applicant pool and to track our progress in attracting and hiring a diverse workforce. The information is optional and will not be disclosed to the hiring manager or the interview team and will not be considered in the hiring process. We appreciate your willingness to share this with us so that we can continue to improve our diversity, equity and inclusion efforts.

  • Video call with a Talent Acquisition team member

To discover your professional project and evaluate if there could be a mutual match.

  • Team interview / Interview with your future manager

To know more about yourself and your achievements, and present to you the team.

  • Technical interview

To evaluate your skills for the position and project yourself into the role.
4.1 Final interview with an Executive Manager
To detail our company’s vision and ambitions for the next couple of years.
4.2 References check
You can start thinking about two contacts who can attest to your previous or current professional experiences. These contacts should be as recent as possible, and we will call them at the end of the process.
Benefits

  • 💰 Package that includes BSPCE
  • 🍜 Lunch voucher (Swile, 9€ at 50%)
  • 👟 Sponsored Wellpass (gymlib)
