How to Apply for Software Engineer - Full-stack

at Swiftly, Inc

🏢 About Swiftly, Inc

Swiftly is at the forefront of urban mobility, using real-time data and AI to make public transit more efficient and sustainable. Working here means directly contributing to reducing urban emissions and improving daily commutes for millions. The company's mission-driven culture and remote-first approach attract top talent passionate about climate tech.

About This Role

As a Full-stack Software Engineer, you'll own end-to-end development of features that enhance transit operations—from real-time tracking to passenger information systems. Your work will directly impact transit agencies' ability to serve riders reliably, making cities greener and more accessible. You'll collaborate closely with product and design to rapidly prototype and deliver solutions that solve real-world transit challenges.

💡 A Day in the Life

Your day might start with a standup with your cross-functional team to discuss progress on a new feature for real-time arrival predictions. You'll spend time coding both backend services (e.g., optimizing data pipelines in Python) and frontend components (e.g., building a Vue.js widget for transit agencies). After lunch, you might pair with a product manager to review user feedback from a prototype and then document architectural decisions for a new API.
