About the Company

Our client is an edtech company serving Latin America with a strong engineering culture. Their product teams work cross-functionally using agile methodologies and build systems that scale across the region.

About the Role

You join a 13-person engineering team leading a year-long platform migration. You migrate features from a TypeScript monolith (AdonisJS) to a service-oriented architecture on AWS, working in sprints alongside the team. This is an execution role: you design, build, and solve concrete problems while maintaining code quality. This role fits someone who wants hands‑on ownership of backend systems and enjoys the challenge of modernizing production platforms.

Key Responsibilities

• Migrate features from the monolithic platform to a service-oriented architecture on AWS.
• Design and build APIs and microservices using event-driven patterns (SNS, SQS, EventBridge).
• Deliver solutions sprint by sprint as the team prioritizes them.
• Participate in daily standups and weekly planning with the engineering team.
• Identify and resolve complex problems while maintaining code quality standards.
• Apply Domain Driven Design principles to build secure, reusable APIs.

Who You Are

• You have at least 2 years of backend development experience with TypeScript and Go.
• You have solid experience with AWS, microservices architectures, and event-driven systems (SNS, SQS, EventBridge).
• You design and build REST APIs securely, applying DDD principles, ideally with TypeScript frameworks like AdonisJS.
• You are comfortable with relational databases, unit testing, and test-driven development.
• You work well in agile environments (Scrum, Sprints) and communicate in functional English.
• You live in Buenos Aires or nearby and can attend the office 2 days per week.

Bonus Points

• Portuguese language skills (part of the team works in Portuguese).
• Experience migrating or modernizing production platforms.
• Experience with non-relational databases.
• Familiarity with other backend frameworks or languages.
• Formal education or degree in systems engineering or related field.

What Success Looks Like

First 90 Days

• You participate actively in sprints and contribute to technical decisions.

Ongoing

• You are a reliable backend contributor who unblocks the team and maintains code quality.
• You help the migration advance on schedule with minimal rework.
• You mentor newer team members and share knowledge about the platform architecture.
