How to apply for Full-Stack Developer

About Le Centre pour la Sécurité de l'IA

Le Centre pour la Sécurité de l'IA (CeSIA) is a nonprofit based in Paris that works on responsible AI development through advocacy, R&D, and ecosystem support. The role is remote, so you would contribute to that work without being in Paris. The organization serves policymakers, researchers, and the public.

About the role

You would maintain and improve multilingual websites used by policymakers, researchers, and the public. The work covers Wagtail and Laravel sites, PostgreSQL migrations, Docker and Git deployments, multilingual content, and the Laravel Nova admin dashboard. You would also handle site health tasks like redirects, accessibility fixes, SEO, and DNS/email deliverability.

A typical day

A typical day might involve fixing a bug in a Wagtail or Laravel site, writing a PostgreSQL migration, and deploying code via Docker and Git. You could also update multilingual content, resolve a translation issue, or adjust the Laravel Nova admin dashboard. Site health tasks like redirects, accessibility fixes, SEO, and DNS/email deliverability would be part of the regular workload.

Who Le Centre pour la Sécurité de l'IA is looking for

• Has hands-on experience maintaining both Wagtail and Laravel applications, including bug fixes, feature work, and content model changes.
• Can debug backend issues and write PostgreSQL migrations without close supervision.
• Is comfortable deploying code with Docker and Git, and managing multilingual content and translation issues.
• Has worked with Laravel Nova or similar admin dashboards, and can handle redirect management, accessibility fixes, SEO, and DNS/email deliverability.

Tips for this application

• Name specific Wagtail and Laravel projects you have maintained, including the content models you changed and the bugs you fixed.
• Describe your PostgreSQL migration experience: what you migrated, how you tested it, and how you deployed it with Docker and Git.
• Give an example of resolving a multilingual content or translation issue on a live site.
• Mention any work with Laravel Nova admin dashboards, even if it was limited to configuration or small fixes.
• Show that you understand site health tasks beyond code: redirects, accessibility, SEO, and DNS/email deliverability.

What to cover in your cover letter

['Your direct experience with Wagtail and Laravel, with concrete examples of maintenance and feature work.', 'Your ability to handle PostgreSQL migrations and Docker/Git deployments in a production environment.', 'Your approach to multilingual content and translation issues, including how you resolve them.', 'Your familiarity with site health tasks like redirect management, accessibility fixes, SEO, and DNS/email deliverability.']

Research before applying

• Read the CeSIA website at securite-ia.fr/en to understand their advocacy, R&D, and ecosystem support work.
• Look at the multilingual sites CeSIA runs and note the languages, content types, and public-facing features.
• Check if CeSIA publishes any technical blog posts or open-source repositories related to Wagtail, Laravel, or AI safety.
• Find out how CeSIA's remote work is structured and whether the team is distributed or based in Paris.

Likely interview topics

Based on the job description, expect questions about:

• How you have maintained a Wagtail site: content model updates, bug fixes, and feature development.
• Your process for writing and deploying a PostgreSQL migration safely.
• How you manage multilingual content and resolve translation issues in a CMS.
• Your experience with Laravel Nova or similar admin dashboards.
• How you handle redirect management, accessibility fixes, SEO, and DNS/email deliverability.

Common mistakes to avoid

• Listing Wagtail and Laravel as skills without showing specific maintenance or feature work on live sites.
• Ignoring the non-code parts of the role: multilingual content, redirects, accessibility, SEO, and DNS/email deliverability.
• Applying without checking what CeSIA does and who its websites serve.
