Job Description

Senior AI Systems Architect

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.

Accountabilities:
  • 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.
Requirements:
  • 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.
Benefits:
  • Health and dental insurance coverage
  • Meal and food allowance
  • Childcare assistance program
  • Extended parental leave
  • Wellness programs and gym partnerships (Wellhub / TotalPass)
  • Profit sharing (PLR)
  • Life insurance coverage
  • Continuous learning platform with technical courses and certifications
  • Discounts and employee perks platform
  • Mental, physical, and well-being support resources
  • Parenting and gestation support programs
  • Language learning and online education platforms.
