Job summary

GetVocal AI Ltd. in Paris seeks a Senior AI Software Engineer to design, build, and operate production-grade backend systems powering real-time conversational AI. You will own low-latency services and event-driven pipelines, integrating LLM APIs and AI tooling at scale.

You will work across AI, backend, and infra teams, shaping modular architectures and high-quality tests, with Docker/Kubernetes and cloud platforms in scope. Fluency in English and strong coding standards are required.

Qualifications

• Expert-level Python skills and strong experience building production backend systems.
• Advanced knowledge of Python asynchronous programming, including asyncio, concurrency, and multiprocessing.
• Strong experience with FastAPI and API architecture.
• Experience building low-latency, high-throughput, or real-time systems in production.
• Strong understanding of distributed and event-driven system design.
• Hands-on experience with technologies such as WebSockets, streaming systems, message queues, Redis and caching.

Responsibilities

• Design, build, and operate production-grade backend systems powering our conversational AI platform.
• Build low-latency, high-throughput services using Python, FastAPI, and asynchronous programming.
• Develop real-time, event-driven systems using WebSockets, streaming technologies, queues, and parallel processing.
• Design distributed architectures that remain reliable and responsive under significant production traffic.
• Build and improve AI agent orchestration systems and LLM-powered applications.
• Integrate LLM APIs, AI frameworks, communication infrastructure, and external AI providers into the platform.
• Use technologies such as Redis and caching layers to improve latency, throughput, and system efficiency.
• Profile production systems, identify performance bottlenecks, and optimise critical execution paths.
• Improve system resilience, fault tolerance, observability, and production debugging capabilities.
• Write comprehensive unit, integration, and load tests.
• Design clean, modular, and maintainable architectures that can evolve as the product scales.
• Work closely with AI, product, and engineering teams to translate agent capabilities into reliable production systems.
• Use AI coding tools to accelerate development, debugging, testing, refactoring, and technical exploration.
• Review and validate AI-generated code for architectural flaws, hallucinations, security issues, and maintainability risks.
• Write a significant amount of production code while improving the overall engineering quality of the platform.
