Full Stack Development Intern Jobs in Sammamish, WA

At Pipe17, our values aren’t just words on a wall. They’re how we operate every day. We are a high-performance team built around ownership , urgency , curiosity , and a strong bias for action . We set bold goals, hold ourselves accountable, and move fast to solve customer problems. Every team member owns their decisions and drives outcomes. No one waits for permission. We operate with urgency , but not recklessly. We focus on what matters most, take initiative, and course-correct quickly when needed. We value people who speak up, follow through, and take pride in their work. Curiosity is how we get better. We ask questions, challenge assumptions, and stay open to new ideas. We don’t default to “how it’s always been done.” We explore, test, and learn. That mindset helps us adapt quickly, solve harder problems, and continuously raise the bar. We also embrace AI as a force multiplier . We believe great operators don’t compete with AI - they partner with it. We use AI to move faster, think deeper, and remove friction from our work, while still applying human juådgåment, creativity, and context where it matters most. Thoughtful use of AI is part of how we scale ourselves and our impact. Finally, teamwork is at our core. We win together, support each other, and celebrate our shared victories. Collaboration across functions is a daily practice, not just something we talk about. We learn from each other, improve constantly, and rally around our mission: unify commerce after the buy button. If these values resonate with how you like to work, you’ll fit right in.

The ideal candidate: AI first - thinks how to solve problems with AI, including with agents. Takes ownership of outcomes, not just assigned work. Moves comfortably between frontend, backend, infrastructure, and AI applications. Makes thoughtful technical tradeoffs between speed, quality, and maintainability. Uses AI to accelerate design, implementation, testing, debugging, and documentation. Learns quickly and enjoys solving difficult, open-ended engineering problems. Collaborates effectively while remaining highly self-directed.

• Competitive salary
• Great healthcare + dental + vision coverage
• Retirement plan
• Pick your own equipment. We'll set you up with whatever Apple laptop + monitor combo you want plus any software you need.
• Unlimited vacation policy. Plus we require you to take at least 2 weeks off each year. We see most employees take 4 weeks off per year. This isn't a vague policy where unlimited vacation means no vacation.
