- agent systems, into impactful
- world solutions.
In this role, you’ll collaborate closely with engineering, product, and client teams to design and deliver
- grade AI features. This includes crafting effective prompt strategies and sophisticated agent flows, implementing Retrieval-Augmented Generation (RAG) pipelines for robust knowledge access, and applying AI to data analysis workflows. You will focus on applying the right tools to the right problems, ensuring our solutions are valuable, reliable, maintainable, predictable, and adhere to strict compliance and security standards through rigorous evaluation and observability practices.
Key Responsibilities
- Integrate and deploy LLM APIs and Models (e. g. , Open
AI, Claude, Mistral, Hugging Face) into applications, internal tools, and backend workflows. - Design and iterate on prompt strategies and agent flows for use cases like customer support, developer tools, data validation, and operational automation.
- Build and maintain AI workflows using orchestration libraries and frameworks (e. g. , Open
AI Agents SDK, Lang
Chain, Lang
Graph, Lite
LLM, RAG pipelines). - Contribute to the development and optimisation of infrastructure for embedding generation, vector search, and metadata enrichment (e. g. , Pinecone, pgvector, Chroma, Cloudflare Vectorize, or Qdrant)
- Ensure AI-powered systems are testable, observable, performant, and aligned with compliance and security standards. (e. g. designing and implementing evals, Open
Telemetry standard) - Stay
-
- date with developments in Gen
AI, ML engineering, and MLOps, and actively assess new tools and techniques. - Contribute to a culture of experimentation, continuous improvement, and
- focused engineering.
- 2+ years of
- on experience in backend software engineering or ML engineering, preferably with a focus on AI applications and agent development - Proficient in Python or Node. js, with experience in building robust and maintainable systems.
- Hands-on experience integrating LLM APIs and/or building ML pipelines in
- world production applications. - Solid understanding of prompt engineering, agentic design patterns, and
- augmented generation. - Familiarity with AI/ML libraries or platforms such as Lang
Chain, Transformers,
- learn, or equivalent. - Experience with CI/CD workflows, Docker, and cloud services (preferably AWS or Azure).
- Strong
- solving skills and a pragmatic,
- oriented mindset. - Fluent in English with strong communication and collaboration skills.
- Exposure to agentic architectures or orchestration tools (e. g. , Lang
Graph, Airflow, Temporal). - Familiarity with vector databases (e. g. , Pinecone, Qdrant, Weaviate, pgvector) or semantic search tools.
- Experience working on data science projects or building ML models beyond LLM use cases.
- Strong understanding and practical application of evaluation strategies and observability for AI systems
One of the perks of being a part of the synvert Group is that you’ll join a global team of over 500 experts from Germany to the UK, Croatia and even the UAE.
