- Contribute to design reviews, technical discussions, and architecture decisions with clear thinking and sound judgment
- Mentor less-experienced engineers through code review, technical guidance, and example-setting
- Help strengthen engineering culture by sharing knowledge, improving standards, and contributing to a collaborative, high-accountability environment
- Leverage AI tools thoughtfully across development, debugging, documentation, and workflow acceleration while maintaining strong engineering judgment

- Strong software engineering fundamentals with experience building product features across frontend and backend systems
- Experience building reliable APIs, services, and user-facing applications in a modern production environment
- Strong software design instincts, including how to decompose complex business problems into maintainable technical solutions
- Solid understanding of databases, data modeling, and tradeoffs across relational databases
- Experience working with modern web application patterns and building polished customer-facing product experiences
- Experience owning projects with meaningful ambiguity and making good technical decisions with incomplete information
- Demonstrated ability to work cross-functionally and drive alignment with stakeholders beyond your immediate team
- Strong debugging and problem-solving skills, including the ability to identify root causes and simplify systems over time
- Clear written and verbal communication skills, especially in design docs, technical tradeoff discussions, and stakeholder updates
- A track record of mentoring teammates and helping raise the quality bar on engineering teams
- A strong sense of ownership, urgency, and accountability for both shipping and operating software successfully
- Comfort working in a fast-paced startup environment where priorities evolve and strong judgment matters
- Practical experience using AI-assisted development tools to improve engineering throughput, learning speed, and quality of execution
- B.S., M.S., or Ph.D. in Computer Science, Engineering, or a related technical field from a top university
- Ability to work a hybrid schedule with work from home on Monday and Friday and in-office collaboration Tuesday through Thursday
