Software Engineer

Responsibilities

• Upsun is the software factory for AI-human workflows. We build the tools that let engineering teams work with confidence, with AI agents and humans working together from the first idea all the way to production. Developers, DevOps engineers, and platform teams use Upsun to move faster without losing control.
• Upsun Cloud: where that software runs. Upsun Cloud handles building, deploying, and scaling what your team ships, with:
• The name says it all. "Up" means uptime, reliability, and acceleration. "Sun" reflects our follow-the-sun-support, a 24x7, globally distributed support team keeping the lights on while you rest. Our core belief is that software should power brighter solutions and greater innovation.
• What's our commonality, our cultural fabric? A curious spirit and a thirst for knowledge; an eagerness for innovative ideas and cultures. We believe we can build anything together in an environment that frees you to do your best work.
• At Upsun, we build tools that shape how developers create, deploy, and run software. That can mean making an entire application environment available for testing or bringing AI agents and developers together in structured workflows. These challenges require thoughtful engineering: making powerful capabilities easy to use while giving teams control over how their software is built and operated.
• Our engineering work connects new possibilities with the demands of established systems. It takes curiosity to investigate beyond the obvious answer, technical judgment to weigh different approaches, and the drive to turn ideas into working software. Across technical backgrounds and time zones, we share expertise, question assumptions, and learn from one another to make decisions and move forward. There’s room for different strengths and perspectives to shape what we build next.
• End-to-end ownership: Design, build, and maintain software within your team’s area, working with teammates from implementation through release and production support.
• Technical decisions: Bring your reasoning to design discussions, consider alternative approaches, and help the team move forward with sound trade-offs between delivery, maintainability, and risk.
• Cross-functional collaboration: Work through interfaces, APIs, and user experience with Engineering, Product, Design, and Support, drawing on the expertise each team brings.
• AI-assisted engineering: Use AI tools to support development and share approaches that improve how the team works.
