????️ What you’ll do as a Backend Developer

You won’t just write code. You’ll architect solutions, shape features, mentor junior devs, and co-create in an Agile environment that’s fast-paced, supportive, and full of opportunity.

Here’s what your day-to-day could include:

• Collaborating with fellow devs and PMs on high-impact, technically challenging projects

• Designing, building and refining backend features using Node.js and TypeScript

• Creating secure, scalable APIs and SDKs for public use

• Improving performance, refactoring legacy systems, and moving us toward a microservices architecture

• Pioneering the smart use of AI in everything that we do

• Mentoring peers and reviewing code (pull/merge requests)

• Partnering with clients and integrating with their systems to become a key part of their data value chain

• Pushing code that meets our high bar for security, performance, and maintainability
