Ensure applications are performant, stable, and responsive.
Uphold high code quality standards through reviews, testing, and automation.
Own the full software development process, from design to deployment.
Plan projects, including roadmaps, deadlines, and task allocation.
Collaborate with stakeholders across Engineering, Product, and Design.
Support team growth through hiring, onboarding, and mentorship.

What We're Looking For

Proficiency in Python and at least one web framework (FastAPI, Django, Flask).
Proficiency in C#, Golang, TypeScript and at least one web framework.
Experience with large-scale distributed systems.
Experience building and leading engineering teams.
Experience working with cross-functional teams, such as Product, Design, and Business.
Knowledge of databases, caching mechanisms, and messaging systems.
Strong problem-solving abilities and attention to detail.
