Design, build, and maintain a scalable internal LLM agent framework and backend services in Python. Ensure observability and reliability via metrics, tracing, and monitoring. Collaborate with ML/NLP teams to adapt the framework for customers, build automated LLM evaluation pipelines, and support integrations and parallel processing for production systems.
Description
We are now expanding our team and are looking for a skilled, goal-oriented backend developer to help us grow. You'll work on services, APIs, databases, and integrations with external systems, collaborating closely with a small, hands-on, technically strong team that moves fast and makes decisions without unnecessary bureaucracy.
Requirements- 6+ years of production experience with Python
- At least 2 years of hands-on experience with async Python (FastAPI, aiohttp, or similar frameworks) in production
- Ability to debug issues across service boundaries
- Strong product mindset, understanding the "why" behind requests and making technical decisions that align with product and business goals.
- Able to navigate ambiguity, adapt quickly to changing priorities, and deliver results despite evolving requirements and limited upfront specifications.
- Open to using AI tools in daily development and troubleshooting
Nice to have:
- Experience with AI Tracing Tools like LangSmith
- Develop and maintain the internal LLM agent framework with focus on scalability, processing, and parallelism
- Ensure system observability and reliability using metrics, tracing and monitoring tools
- Adapt the framework for specific customer use cases and collaborate closely with ML/NLP teams
- Build and support automated LLM evaluation pipelines
- Design backend services using Python () and modern cloud-native architecture.
- The team has built award-winning AI products for tech corporations: devices, voice assistants, products that are actually in the world
- Cutting-edge tech stack: Speech Technologies, NLP, Generative AI (LLMs, diffusion models), voice-first agentic architecture with privacy-first and on-premises deployment
- High engineering bar and real ownership: the team cares about what actually works in production, not what looks good in a demo, and you'll see the impact of your work directly
- Fast career progression: a senior-heavy team and a high volume of real problems means you grow faster than you would anywhere else
- Startup pace with enterprise stability: real clients, real revenue, no bureaucracy
- Fully remote across Europe
- 21 vacation days + public holidays + 5 sick days
- Private English lessons via Preply
- Company-paid subscriptions to top AI tools (ChatGPT, Claude, Cursor, and others)
