About Upsun

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 brings this together through two products: one that shapes the work, and one that runs it.

• Upsun Dispatch™: where your team and AI agents work together. Upsun Dispatch keeps the right humans in the loop at the right moments, with human approval built in, full visibility into what’s happening, and no surprises on the bill. Agents do the volume and your team holds the line.
• Upsun Cloud: where that software runs. Upsun Cloud handles building, deploying, and scaling what your team ships, with:
  • Predictable performance, even at scale
  • Secure, compliant environments by default
  • Real-time observability and cost transparency
  • Cloning, configuration, and provisioning in seconds

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.

Our values:

🌿 We make a positive impact.

✨ We aim for the stars.

💚 We care for each other.

Impact of an Engineering Intern

As an Engineering Intern on our Site Reliability Engineering (SRE) team, you will help keep the platform that runs our customers’ applications reliable, efficient and cost-effective. You will work on clear, high-visibility projects with measurable impact. You will use AI tools every day to learn faster, explore our systems and get work done, with direct guidance and mentorship from a senior SRE.

This internship is based on-site in our Paris office, France. The duration is 6 months.

What to expect

• Improve our infrastructure: Contribute to projects that make our platform cheaper, faster or more reliable. Start with well-scoped tasks and grow from there.

• Work efficiently: Use AI assistants, such as Claude or Codex, to explore unfamiliar code, draft and review changes, write scripts and documentation, and troubleshoot problems. Help the team find new ways to use AI in SRE work.

• Test first: Try each change in a safe test environment before it reaches production. Every step is reviewed and can be rolled back.

• Measure the impact: Compare cost, performance and reliability before and after each change. Your findings will shape the team’s next steps.

• Learn with your mentor: Grow your Computer Science knowledge through regular one-to-ones, pair programming and shadowing. You prepare and test each change, and your mentor reviews every production change with you.

• What comes next: After your first project, you may explore other areas of SRE work, based on your interests and the team’s needs.

What you bring

• Relevant studies: Current studies or recent graduation in computer science, engineering or a related field.

• Technical Curiosity: A good understanding of how computers and software behave, and a wish to learn how large systems run behind the scenes. You don’t need experience with any specific tool or technology.

• Hands-on with AI: You already use AI assistants, such as Claude, ChatGPT or Codex, to learn, build or solve problems. You check their output carefully instead of trusting it as-is.

• Problem-solving mindset: You break problems into smaller steps, look for the cause when something does not work, and try new ideas.

• Ownership and persistence: A habit of taking a task from start to finish, and asking for help at the right time.

Bonus

• A personal, school or open-source project where you wrote code or scripts, in any language.

• First experience with a cloud platform, Linux or the command line.
