Senior Fullstack Software Engineer (Python) - AA, Remote: Colombia - Costa Rica, Fulltime

About this role

Gorilla Logic is looking for a Senior Software Engineer, Full-Stack with strong backend expertise in Python to join an established engineering team building and scaling an automated evaluation platform for agent-oriented software products.

This is a backend-heavy, hands-on engineering role focused on building production services and durable workflows that evaluate third-party applications through APIs and browser-driven interactions. You will work with significant autonomy, taking technical problems from discovery and design through implementation, testing, and production release.

You’ll collaborate directly with a US-based client team and cross-functional partners while working with technologies including Python, FastAPI, durable execution frameworks, Docker, Kubernetes, Argo CD, and AWS.

Responsibilities

• Design, build, and maintain production backend services using Python and FastAPI.
• Build and extend systems that orchestrate automated evaluations of third-party software products.
• Develop long-running background jobs and durable workflows that are resumable, reliable, and observable.
• Integrate with third-party APIs and systems, including authentication, rate limiting, retries, partial failures, and changing external contracts.
• Build and improve browser-driven automation workflows when APIs are unavailable or insufficient.
• Instrument evaluation workflows to ensure results and failures are measurable, reproducible, traceable, and easy to diagnose.
• Analyze evaluation results and continuously improve configurations, fidelity, and coverage.
• Design solutions that are scalable, maintainable, observable, and production ready.
• Build, test, and maintain containerized applications deployed through established CI/CD and Kubernetes environments.
• Use AI-assisted and agentic software engineering tools throughout planning, development, testing, and maintenance.
• Take ambiguous technical requirements and independently develop practical, defensible implemen...
