Data Engineer - AI Safety / Data API / Snowflake / ClickHouse

We're partnered with a genuinely exciting AI safety startup focused on building the safety, reliability, and optimization layer for advanced AI systems.

Their platform uses natural language policies to define model behavior, which are automatically tested and improved at scale. Backed by eleven million dollars from leading investors, the team trains proprietary LLMs that run faster and more efficiently than open source and commercial options. This is a small, focused team where you will work on challenging problems and ship quickly.

They're seeking an AI Research Engineer to join them team on a permanent basis, working on a hybrid model at their HQ in Paris.

What You’ll Do:

• Build and maintain a clean, scalable data environment, enabling teammates to access petabytes of traces, logs, and model outputs in the formats they need - without delays or manual data wrangling.
• Develop internal data APIs, SDKs, and tooling that let engineering, product, and research teams discover, query, and use data without managing infrastructure.
• Monitor and optimize data performance—from storage layouts to query execution plans—to ensure analytics and research workflows stay fast as data volumes surge.
• Own data access and governance, defining and enforcing permissions, access controls, and security policies.

What We’re Looking For:

• Experience building or scaling a modern data stack (e.g., Snowflake, ClickHouse, event streaming systems) in a startup or similarly fast-moving environment.
• Strong SQL and Python skills, with comfort working on large, noisy datasets.
• Clear communication and the ability to collaborate directly with engineers and researchers. Fluent English.
• Bonus: experience with Metabase, Tableau, or similar internal dashboarding tools.

Compensation & Benefits:

• Competitive salary + equity
• 20 days of paid vacation
• Hybrid work from Paris with relocation support
• Top-tier medical insurance
• All required hardware, tools, and services provided
• Paid subscriptions for AI agents and developer tools
• Twice-yearly team off-sites (recent destinations include the Alps and Saint-Tropez)

Visa sponsorship and visa support is on offer, so international applicants are encouraged.
