Job Description
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior AI Systems Architect based in Brazil.
This role sits at the forefront of AI-driven software engineering transformation, shaping how modern systems are designed, built, and evolved through agentic AI workflows. You will lead the definition of AI-first architectures that reimagine traditional SDLC practices into autonomous, intelligent systems powered by specialized agents. The scope spans across engineering, DevOps, QA, product, and operations, requiring a strong systems-thinking mindset and deep architectural expertise. You will design scalable ecosystems where AI agents collaborate, execute tasks, and continuously improve software delivery processes. This is a highly strategic and hands-on role, combining platform architecture, AI engineering, and innovation leadership. You will operate in a complex enterprise environment, influencing both technical direction and engineering culture.
- Design and orchestrate end-to-end AI-driven workflows across the software development lifecycle, from requirements definition to deployment, operations, and continuous improvement.
- Architect agent-based systems that enable autonomous execution of engineering tasks, promoting an AI-first approach to software delivery.
- Build and evolve specialized AI agents for development, QA, DevOps, product management, and operational support functions.
- Define strategies for context management, prompt engineering, and token optimization to ensure efficient and reliable LLM performance.
- Structure and maintain knowledge bases, architectural decision records (ADRs), and technical documentation to ensure consistency and reuse across AI systems.
- Develop evaluation frameworks (Evals) to monitor agent quality, accuracy, and behavior, driving continuous improvement and reducing hallucinations.
- Ensure compliance with internal standards, security policies, and architectural governance across all AI-driven systems.
- Act as a technical reference for the evolution of AI platforms and multi-agent ecosystems applied to software engineering.
- Strong background in Software Architecture, Platform Engineering, or Senior Software Engineering roles with enterprise-scale systems experience.
- Proven experience designing distributed systems, APIs, and microservices-based architectures.
- Hands-on experience with Agentic AI workflows, AI engineering, or applying LLMs within the software development lifecycle.
- Strong expertise in prompt engineering, context management, and optimization of LLM interactions.
- Ability to translate business logic and technical knowledge into structured workflows and agent-based heuristics.
- Solid understanding of observability, monitoring, and system behavior analysis in production environments.
- Experience with scalable system design and engineering best practices, including reliability and performance considerations.
- Strong analytical thinking, problem-solving ability, and strategic architectural vision.
- Advanced English proficiency for technical communication and documentation.
Differentials:
- Experience with Python development.
- Knowledge of RAG (Retrieval-Augmented Generation) architectures.
- Exposure to MCP (Model Context Protocol) and tool-augmented AI systems.
- Experience with multi-agent systems and autonomous workflow design.
- Familiarity with ML concepts such as fine-tuning and model evaluation.
- Experience with observability tools such as Datadog.
- Background in telecom, billing, or payments systems.
- Exposure to AI platform engineering, Harness engineering, or AI-driven SDLC frameworks.
