- Translate product vision into technical reality, collaborating closely with the Product team.
- 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.
- Ownership mindset and ability to ship products end-to-end.
- Excellent communication skills and a low-ego, team-first attitude.

## What We Offer

We offer a comprehensive benefits package designed to support your well-being, growth, and work-life balance.
