• Continuously explore and implement new technologies, tools, and frameworks to optimize development processes and product performance.
• Share knowledge with teammates through pairing, contributing to documentation, and offering constructive feedback to maintain high-quality standards and build a culture of learning on the team.

• Experienced Leader: You have a proven track record of designing and implementing scalable software solutions, with 4+ years of hands-on experience in software development and a history of mentoring team members.
• Adaptable Innovator: You stay ahead of industry trends, have integrated AI tools like Claude Code into your daily workflow, and have informed opinions about where they help and where they don’t.
• Problem-Solver: You excel at identifying technical challenges and developing innovative, effective solutions. You feel comfortable designing and building systems to solve complex problems.
• Pragmatic: You balance quality with speed, and you know when it's the right time to invest in future-proofing your work. When it matters, you are meticulous about making your code reliable, performant, and forward-looking.
• Driven by Impact: You are motivated by the opportunity to contribute to a mission-driven company and to build technology that makes a difference.
