The Role
We're building the next generation of real-time conversational AI systems.
Our research team is focused on advancing the intelligence layer of our agents. What we're missing is a strong engineer to own the
execution layer
— the systems that make this intelligence work reliably, at scale, and in real time.
This role sits at the intersection of
AI, backend engineering, and infrastructure
.
You will take ownership of the engineering backbone behind our AI agents: performance, latency, reliability, and scalability.
What you'll do
- Own and evolve the backend systems powering our conversational AI platform.
- Design, build, and optimise real-time systems with a strong focus on latency and performance.
- Maintain and improve our server stack, pipelines, and production infrastructure.
- Develop scalable APIs and services using Python and FastAPI.
- Work closely with the AI research team to integrate new models, ideas, and agent capabilities into production.
- Support and optimise integrations with multiple AI providers.
- Identify bottlenecks, fix bugs, resolve tickets, and continuously improve system reliability.
Requirements
What we'are looking for
- Strong backend engineering fundamentals with a product mindset.
- Expert-level Python skills and experience building production systems.
- Strong experience with FastAPI and asynchronous programming.
- Experience building low-latency, high-throughput systems in production environments.
- Hands-on experience with MLOps tooling (Docker, Kubernetes, GPU workloads).
- Experience working with LLMs, AI agents, or deploying AI systems into production.
- Ability to work closely with research teams and translate ideas into scalable systems.
- High ownership, speed, and pragmatism.
What this role is
- This is not a research role.
- You will not be writing papers or training foundation models.
- You will be the person who makes AI actually work in production.
Benefits
What we offer
- High ownership and autonomy
- Diverse, international team across Europe
- Exposure to cutting-edge AI, voice, and enterprise deployments
- Fast-paced environment with strong learning curve
- 25 days holiday + public holidays
- Private healthcare (based on country- but for France it's 50% coverage for you, and 100% Coverage for your kids
- Swile (France only)
- Pension contribution
- ESOP/VSOP (shares)
