Résumé du poste

Darwoft in LATAM is seeking a Senior/Staff Software Engineer to join a remote, AI-native software platform for M&A SaaS. You will navigate a large codebase, design features, and balance speed with reliability while using AI coding agents to accelerate delivery.

The role emphasizes production software, architecture, and modern cloud practices; you will own critical components and collaborate with product leadership to deliver scalable solutions.

Qualifications

• Strong professional experience building and operating production software systems.
• Excellent software engineering fundamentals, including architecture, system design, debugging, testing, and maintainability.
• Experience working with large or complex existing codebases.
• Strong backend or full‑stack engineering experience using modern programming languages and frameworks.
• Experience building modern web applications and SaaS products.
• Strong understanding of APIs, application architecture, integrations, data modeling, and distributed systems.
• Experience with relational databases and production data environments.
• Strong understanding of automated testing and modern software development practices.
• Familiarity with cloud environments, CI/CD pipelines, deployments, and production operations.
• Ability to reason through technical trade‑offs and make pragmatic architectural decisions.
• Strong ownership and ability to work independently in an evolving product environment.
• Product mindset: you understand not only how to build something, but also why it should be built.

Responsabilités

• Navigate, understand, 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 continues to scale.
• Identify technical debt, architectural risks, reliability issues, and opportunities for improvement.
• Use Claude Code, Codex, Cursor, Copilot, or similar AI coding agents extensively throughout the software development lifecycle.
• Leverage AI agents to explore codebases, design implementations, generate and refactor code, debug issues, write tests, and accelerate delivery.
• Build and evolve backend services, APIs, integrations, data models, and application workflows.
• Contribute across the application stack when needed.
• Strengthen automated testing, maintainability, observability, reliability, and production readiness.
• Improve development workflows, tooling, automation, and engineering practices.
• Troubleshoot complex issues across application, data, and infrastructure layers.
• Balance development speed with software quality and long‑term maintainability.
• Work closely with product leadership to translate business problems into effective technical solutions.
• Help a small engineering team achieve significantly greater development leverage through AI‑assisted engineering.
