About the role
At Shakers we're partnering with a leading global technology consultancy on a new project for a major North American retailer. They're building an AI-driven engineering platform that changes how software gets made, from requirements and design to testing and production. We're looking for a Senior AI Platform Engineer based in Portugal to join as a freelancer, full time.
Responsibilities
•Design and build agentic development workflows, tools and automation across the SDLC
•Develop and integrate AI agents: orchestration, tool use, MCP servers and context engineering
•Implement evaluation frameworks, guardrails and quality checks so agent outputs are reliable
•Build and optimize CI/CD pipelines, infrastructure automation and developer tooling
•Connect AI workflows with enterprise systems such as Jira, source control and CI platforms
•Improve engineering efficiency, reliability and developer experience
Requirements
•8+ years in software engineering, with senior or lead responsibilities
•Proven experience building and deploying AI agents in production (orchestration, MCP, evals). PoCs alone won't be enough
•Strong background in Platform Engineering, DevOps and CI/CD
•Python and TypeScript
•Cloud infrastructure (GCP or equivalent) and Infrastructure as Code (Terraform or similar)
•Experience building internal developer platforms, CLIs or workflow engines
•Daily hands-on use of agentic coding tools

Nice to have
•Cursor, Claude Code or similar AI development tools
•Knowledge graphs, static analysis or code intelligence tooling
•BDD/Cucumber, contract testing or mobile test automation (Maestro)
•Kotlin, Go or Rust
Conditions
•You'll work on one of the most interesting problems in software right now: making AI agents genuinely useful for engineering teams at enterprise scale
•Hybrid with just 1 day a week on-site, in Lisbon, Braga or Coimbra
•Freelance, full time, with a high-autonomy role where you own the technical decisions
•Start ASAP
