Job summary

Darwoft is seeking a Senior/Staff Software Engineer to join an AI-native engineering approach on a modern SaaS platform. This 100% remote, LATAM-friendly role focuses on production software, architecture, and reliability, rather than ML model work.

You will navigate a large codebase, drive architectural decisions, and leverage AI coding agents to accelerate delivery while maintaining quality.

Qualifications

Experience building and operating production software systems.
Strong fundamentals: architecture, system design, debugging, testing, and maintainability.
Experience with large or complex existing codebases.
Backend or full-stack with modern languages and frameworks.
Experience building SaaS products and web applications.
Knowledge of APIs, architectures, data modeling, and distributed systems.

Responsibilities

Navigate and evolve a large existing production codebase.
Design and implement new product capabilities across a complex SaaS platform.
Make pragmatic architectural and system design decisions as the product scales.
Identify technical debt and reliability issues for improvement.
Use Claude Code, Codex, Cursor, Copilot, or similar AI agents extensively.
Leverage AI agents to explore codebases, generate/refactor code, and test.
Build and evolve backend services, APIs, data models, and workflows.
Strengthen automated testing, observability, and production readiness.
Improve development workflows, tooling, and engineering practices.
Collaborate with product leadership to translate business problems into tech solutions.
