Senior Python Developer

This is us

At Avenga, we believe that human creativity empowers technology that matters. Operating globally, our 6000+ specialists provide a full spectrum of services, including business and tech advisory, enterprise solutions, CX, UX and Ul design, managed services, product development, and software development.

This is you

• 6–8 years of professional experience as a Software Engineer, with strong Python expertise.
• Proven track record of delivering production-grade data/ML services on public cloud platforms (GCP preferred, AWS/Azure also acceptable).
• Deep hands-on experience with orchestration frameworks like Airflow, Dagster, or Prefect.
• Strong knowledge of vector databases and similarity search tools, such as FAISS, Milvus, Pinecone, or ideally Google Vertex AI Vector Search.
• Solid understanding of the LLM ecosystem: model families (GPT-4o, Gemma 2, Mistral), prompt engineering, embeddings, fine-tuning with LoRA/PEFT, and RAG patterns.
• Experience integrating with LLM APIs (OpenAI, Google GenAI / Vertex AI, or Anthropic) via REST or gRPC.
• Strong grasp of software architecture patterns: event-driven design, microservices, Pub/Sub.
• Comfortable with CI/CD pipelines (GitHub Actions, Cloud Build) and infrastructure-as-code tools like Terraform.
• BS/MS in Computer Science, Electrical Engineering, or equivalent practical experience.
• English level: Upper-intermediate or above.
• Must be based in Argentina.

Nice-to-have skills:

• Experience deploying workloads on Vertex AI Vector Search, Gemini, or PaLM2 / Gemini Pro.
• Familiarity with serverless and event-driven architectures.
• Exposure to ad-tech data (bid requests, impression logs, CTV graphs).
• Experience with real-time data processing frameworks.

This is your role

• Designing and building core data services that ingest, vectorize, and retrieve large-scale first-party data signals.
• Partnering with data scientists to operationalize open-source and commercial LLMs (e.g., OpenAI, Gemini, Claude) on Google Cloud Platform.
• Implementing scalable and performant ETL/ELT pipelines, enabling downstream machine learning and analytics workloads.
• Developing intelligent systems that support RAG-based architectures, semantic search, and campaign personalization.
• Contributing to platform automation and MLOps best practices through robust CI/CD pipelines and infrastructure as code.
• Supporting a modern, cloud-native data architecture aligned with real-time business needs.
