This position is based in Mexico City.

Summary of Role:

As a Software Development Engineer III at Palmetto, you will play a key role in designing, building, and scaling critical platform services using the MERN stack (MongoDB, Express, React.js, Node.js). You’ll work hands-on across the stack, with a stronger emphasis on server-side architecture and API development, while collaborating closely with product, design, and engineering teammates.

This role is ideal for a passionate, growth-minded engineer who thrives in an Agile environment, brings ideas to the table, and has the technical depth to contribute to platform evolution and system scalability.

You’ll work alongside, not for, other team members – contributing your ideas, code, and energy to shape solutions that drive business outcomes and customer satisfaction.

Key Responsibilities:

Strategic & Tactical 

• Design and implement scalable client- and server-side solutions, with an emphasis on APIs, backend services, and database integration.
• Write high-quality, testable, and maintainable code across the full stack.
• Develop and maintain comprehensive unit, integration, and end-to-end tests.
• Diagnose and troubleshoot production issues and propose robust solutions.
• Participate in Agile ceremonies (planning, grooming, retrospectives) and contribute to meaningful story estimations.
• Engage in architectural discussions, technical design reviews, and contribute to Palmetto's engineering standards.
• Identify and advocate for opportunities to improve system performance, reliability, and developer productivity.
• Partner cross-functionally with product managers, designers, and QA to deliver well-rounded user-centric solutions.

Team & Culture

• Actively participate in peer code reviews with a focus on knowledge sharing, mentorship, and maintaining high-quality code standards.
• Collaborate openly with others to help cultivate a culture of learning, innovation, and continuous improvement.
• Demonstrate an ownership mindset by anticipating future needs and contributing to long-term technical roadmap discussions.

Minimum Qualifications 

• 5+ years of professional software engineering experience.
• Strong proficiency in JavaScript (ES6+) and understanding of the JavaScript object model.
• Proficiency with Node.js, Express, and experience designing/consuming RESTful APIs.
• Experience building and maintaining Single Page Applications (SPAs) with React.js.
• Hands-on experience working with NoSQL/document-based databases (e.g., MongoDB).
• Solid understanding of core web fundamentals (HTML, CSS, security, performance).
• Strong unit and integration testing discipline; TDD experience a plus.
• Familiarity with CI/CD pipelines, code versioning (Git), and modern development workflows.
• Excellent written and verbal communication skills.
• Strong problem-solving skills, a continuous learner mentality, and a commitment to team success.

Preferred Qualifications 

• Experience with Fastify, NestJS or other Node.js frameworks beyond Express.
• Familiarity with server-side rendering concepts and isomorphic React applications.
• Knowledge of authentication and authorization patterns (e.g., OAuth, JWT).
• Experience with front-end build tools (Webpack, Vite, Babel, etc.).
• Exposure to containerization (Docker) and cloud platforms (AWS, GCP, Azure).
• Interest or experience in microservice architecture and event-driven systems.
• Practical knowledge of Agile methodologies, pair programming, and code review practices.
• Enthusiasm for building clean, scalable, and maintainable code.
