Full Stack Developer – Node.js / React

Spoiler: This is where your next big move begins.

What this Journey Looks Like

At Pearster, we’re looking for an experienced Senior Full Stack Developer with strong Node.js expertise to join an international project with an important Canadian fintech client.

We’re looking for a proactive developer with strong English communication skills and experience migrating applications.

This is a remote opportunity for professionals based in LATAM, working in EST hours.

You’ll join an international project focused on application migration, collaborating with a Canadian fintech client and distributed teams.

The initial focus of the project will be migrating applications from an older version of Node.js that is approaching end of support to a newer, supported version.

After the migration is completed, you’ll continue working with the team, providing ongoing support and maintenance for the applications running on the new Node.js version.

The main technology stack is Node.js for the backend, MongoDB for storage, and React for the frontend.

This opportunity is ideal for a senior developer who can bring strong Node.js expertise, proactively identify potential issues, and take ownership of technical challenges throughout the migration and post-migration phases.

What You'll Lead and Build

• Contribute to the migration and modernization of existing applications.

• Upgrade applications from an older Node.js version to a newer, supported version.

• Identify and resolve compatibility issues, dependencies, and technical challenges related to the Node.js upgrade.

• Provide ongoing support and maintenance after the migration, working with the applications in the new Node.js environment.

• Develop and maintain backend solutions using Node.js.

• Work with MongoDB for data storage.

• Develop and maintain frontend applications using React.

• Collaborate with technical and cross-functional teams throughout the migration and post-migration phases.

• Proactively identify challenges and contribute to technical solutions.

What You Bring to the Table

• Senior-level professional experience with Node.js and backend development.

• Strong, hands-on Node.js expertise, with the ability to independently troubleshoot and solve complex backend issues.

• Experience upgrading Node.js versions and/or migrating applications between different runtime or framework versions.

• Strong understanding of Node.js dependencies, compatibility issues, and application maintenance.

• Experience developing and maintaining production applications with Node.js.

• Experience with MongoDB.

• Experience with React.

• Ability to take technical ownership and work independently when solving migration and application issues.

• Proactive mindset and strong communication skills.

• Advanced English to communicate confidently with an international client and team.
