Senior Software Engineer - AI at Beyond – Buenos Aires | Jobyssey

As our hiring team is international, we kindly ask that you submit your CV in English to ensure it can be reviewed by all stakeholders.

Work where work matters.

We are a global technology group built for what's next, offering high calibre professionals the platform for high stakes work, the kind of work that defines an entire career. When you join us, you're not just taking on projects, you're solving problems that don't even have answers yet.

You will join an exclusive roster of talent that global leaders, including Google, Snap, Diageo, PayPal, and Jaguar Land Rover call when deadlines seem impossible, when others have already tried and failed, and when the solution absolutely has to work.  

Forget routine consultancy. You will operate where technology, design, and human behaviour meet to deliver tangible outcomes, fast. This is work that leaves a mark, work you’ll be proud to tell your friends about.

We are looking for a Senior AI Engineer with deep expertise in Vertex AI, Python, and Large Language Models to join our Americas team. In this role, you will be responsible for architecting and deploying the production-grade AI solutions that power next-generation intelligent applications for our enterprise clients in North America. Based in Argentina, you will act as a core technical pillar for the region, bridging the gap between client requirements and high-performance delivery. You will focus on engineering excellence, specifically in the realms of generative AI, RAG architectures, and agentic systems, while collaborating with our global engineering teams in Europe.

We look for people who embody:

Innovation to solve the hardest problems.

‍Accountability for every result.

‍Integrity always.

About The Role

Architect AI Solutions: Build and deploy production-grade AI features, including RAG (Retrieval-Augmented Generation) pipelines, LLM orchestrations, and Agentic workflows using Vertex AI.
Develop Core Logic: Write clean, maintainable, and highly efficient code in Python to support AI model integration and data-intensive applications.
Optimize Model Performance: Fine-tune models for specific business logic and optimize LLM prompts to ensure accuracy, relevance, and safety for enterprise use cases.
Engineer Data Sources: Optimize and manage data sources and vector databases to ensure high-quality retrieval for context-aware AI systems.
Collaborate Globally: Work closely with US-based product owners and European delivery teams, requiring a proactive communication style and flexibility for early-morning syncs.
Ensure Quality: Champion best practices in AI observability, evaluation frameworks, and automated testing to ensure the reliability of enterprise-level deployments.
Consult with Clients: Partner with clients to develop new AI concepts and enhancements, translating business goals into technical AI roadmaps.

This role is designed for impact, and we believe our best work happens when we connect. While we operate a flexible model, we expect you to spend regular quality time on site (at our offices or a client location) for collaboration sessions, customer meetings, and internal workshops.

What Success Looks Like

Engineering Experience: Extensive professional experience in software engineering, with a significant focus on AI/ML implementation.
AI/ML Integration: Mastery of the Vertex AI ecosystem and proven experience integrating LLMs into production-grade applications.
Python Expertise: Mastery of the Python ecosystem, specifically libraries used for AI development and data manipulation.
GCP Proficiency: Hands-on experience with Google Cloud Platform services, specifically Vertex AI, BigQuery, and Cloud Functions.
DevOps Skills: Proficiency with Docker and CI/CD pipelines as they apply to MLOps workflows.
Communication: Fluent English skills with the ability to discuss technical trade-offs clearly with both peers and stakeholders.

Nice to Have

AI Frameworks: Deep experience with LangChain or LlamaIndex.
Data Engineering: Understanding of data pipelines and ETL processes to support AI model training and retrieval.
Advanced RAG: Experience with sophisticated retrieval techniques and vector search optimization.
Certifications: GCP Professional Machine Learning Engineer.
