Who You Are

We're not looking for specific tech stacks — we're looking for passionate problem solvers who are excited to make an impact. You might be a great fit if you:

• Have backend development experience and are comfortable with Java, MySQL, AWS, DropWizard, Kafka, Kubernetes, or similar technologies (expertise in specific tools isn’t a deal-breaker)
• Are deeply user-focused and empathetic, understanding the challenges our customers face and how they move through our product
• Enjoy tackling both technical challenges and business problems, and thrive when you're close to go-to-market strategies
• Collaborate well with others, take ownership of your work, and are eager to “figure things out” in a supportive, innovative environment
• Have demonstrated the ability to solve complex technical problems while weighing tradeoffs, with a deep understanding of developer experience and business needs
