Staff Software Engineer (AI-Native Full-Stack)

About the role

At South Geeks, we engage top-performing Software Engineers, Security Experts, and Data Analysts from Latin America to join our clients' teams worldwide. For over 8 years, we've been helping future-shaping companies scale faster by curating world-class tech talent and building long-lasting, strategic partnerships. We pride ourselves on a people-centered culture that powers innovation, collaboration, and excellence. About the Client Our client is a fast-growing US-based edtech company whose platform powers school-family communication for over 22 million students across the country. Their engineering team is navigating an exciting architectural transition, while continuing to ship fast. This is a high-visibility role with regular interaction with the CEO and co-founders. We are looking for a Staff Software Engineer who operates with urgency and a "multiplier" mindset. This is an AI-native role: you should have fundamentally evolved your development workflow using LLMs and AI agents. The ideal candidate uses AI to bypass manual boilerplate, accelerate debugging, and ship clean, simple functionality at a pace traditional methods can't match. You'll be one level below Principal, but the expectations for technical leadership and architectural influence are high.

Responsibilities

• Partner with product, exec leadership, design, sales, and marketing to build the right things, as simply as possible
• Champion AI development practices and mentor the engineering org on using AI to increase sprint velocity and code quality
• Build and run systems that operate robustly at scale with the highest level of security
• Work with leadership to build a unified technical direction and a culture of excellence and speed
• Review PRs and design the future architecture of systems, including the evolution of legacy monolithic architecture toward a modern stack
• What You Need to Succeed in This Role
• Mastery of large-scale services using Ruby, Python, JavaScript/TypeScript and PHP
• Deep knowledge of distributed systems, relational databases (MySQL/Postgres), and AWS infrastructure (Aurora, RDS, SQS)
• AI-native workflow: you treat AI (Cursor, Claude Code, etc.) as your primary partner in the development lifecycle - using it to bypass boilerplate and focus on deep architectural work
• Ability to represent the engineering team in high-stakes discussions with non-technical stakeholders
• Bachelor's degree or higher in Computer Science or a related field
• Our Team
• We strive to create an inspiring and growth-oriented environment where everyone feels valued, heard, and empowered. We promote both personal and professional development, with individualized support for your needs and concerns. We aim to build a space where everyone can thrive.
