Job summary

Orasio in Paris is seeking a Senior Fullstack Engineer to build real-time monitoring interfaces and large-scale video investigation platforms.

You will work across React frontends and FastAPI backends, using Python, TypeScript, PostgreSQL, and vector search, in a data-sensitive on-premise hybrid setup. The role emphasizes pragmatic coding, strong testing, and collaboration with ML and platform teams.

Qualifications

• 5+ years of experience in fullstack development, with a track record of shipping production-grade web applications.
• Backend: solid experience with Python and FastAPI (or equivalent async Python frameworks).
• DB: strong experience with large PostgreSQL at scale: schema design, migrations, query performance.
• Frontend: strong expertise in React and TypeScript. Comfortable with modern tooling and writing maintainable, testable UI code.
• Good grasp of system design, REST API design, async programming, and the trade-offs of building real-time, event-driven systems.
• Pragmatic about engineering: writes the minimum code that solves the problem, prefers enhancing existing code over duplicating it, and is rigorous about types, tests, and code quality.
• Comfortable navigating a monorepo and a polyglot stack (TypeScript + Python).
• Familiar with AI tooling for the developer experience.
• Mission-driven, autonomous, and thrives in fast-paced environments.
• Fluency in French and English.

Responsibilities

• Design, develop, and maintain fullstack features across our React frontends and our FastAPI backends.
• Develop backend services that ingest, persist, and serve data flowing from our edge pipeline (PostgreSQL, vector search, MQTT).
• Build and evolve real-time interfaces for video monitoring, investigation, and alert workflows including video playback, map-based geospatial views, and live event streams.
• Integrate with third-party Video Management Systems and customer infrastructures.
• Contribute to our shared TypeScript and Python libraries used across products.
• Care about performance, reliability, and security across the stack. Our products run in constrained, air-gapped, on-premise environments.
• Participate in architecture discussions, code reviews, and product planning. Push back on complexity, advocate for clean abstractions, and help raise the bar of the codebase.
• Collaborate closely with ML engineers to surface model outputs into product experiences that operators can actually trust and act on.
