Senior Software Engineer Jobs in Rancho Cucamonga, CA

Swiftly is on a mission to help cities move more efficiently. We are the leading transit data platform for agencies to share real-time passenger information, manage day-to-day operations, and improve service performance. Today, over 200 transit agencies in 12 countries – including LA Metro, MARTA, SEPTA, and MBTA – rely on Swiftly to improve on‑time performance by up to 40% and increase passenger information accuracy by up to 50%. The result is better service reliability, increased ridership, and more efficient transit operations.

Even though Swiftly’s HQ office is located in San Francisco, CA, we are open to candidates in most locations across the U.S. as well as Ontario and British Columbia, Canada. At this time we are unable to provide Visa sponsorship.

Engineering at Swiftly is not only about writing code – we believe in creating empowered product teams that work together to conceptualize new features and bring them to life. Each team aims to strike a balance between delivering incremental improvements, creating prototypes to test new ideas and mitigate risks, and building scalable software using industry best practices. We’re guided by a mission to positively impact transit riders, and we embrace humility and intentionality in how we make technical decisions so that we best meet our customers’ needs.

Swiftly is looking for a Senior Software Engineer with experience building scalable cloud‑based services.

Our backend environment includes Java, Node.js, and Python; our MV* framework of choice is Vue.js, but we welcome applicants who are excited to work across languages and have strong experience with any major MV* framework.

We encourage you to apply if the above is exciting to you and if you meet half or more of the below requirements. Above all else, we value candidates who angle toward growth, leveraging a positive attitude and the aptitude to relentlessly seek and solve problems to deliver impact. We know the tech landscape is ever‑changing and strongly support individual growth. If this is exciting to you, then we’d love to talk!

• Apply modern software engineering practices to deliver robust, maintainable, and extensible systems
• Uplevel teammates through code reviews, pairing, and strong collaboration
• Take ownership of your code and product domain, engaging in retrospectives and continuously improving how the team works

• Experience with cloud‑native architectures and services (AWS preferred)

• Continuous learner who embraces emerging technologies and helps others grow
• Collaborative team player who contributes wherever needed to support team goals
