II Software Engineer

Job Objective:

We're growing fast and looking for a Software Engineer who could transition to Founding Engineer to lead teams.

If you're passionate about building, consider yourself top-tier, and love launching high-quality products quickly, we want to know you.

We don't care where you're from, where you studied, or how many years of experience you have. If you believe you're in the top 1% at creating and executing code, we want you on the team.

We're looking for people who want to join a family with a clear mission. The hours are long, but so is the mission and the upside.

Responsibilities:

• Own major product decisions and technical architecture.
• Ship fast and iterate based on real customer feedback.
• Build for enterprise scale from day one.
• Design, develop, and maintain scalable, high-performance applications, frontend and backend (we move where the product needs us).
• Collaborate with the founding team to define technical architecture and establish engineering best practices.
• Build end-to-end features with high standards of quality, speed, and scalability.
• Ensure system reliability, security, and efficiency in production environments.
• Contribute to the product roadmap by proposing innovative and scalable solutions.
• Participate in code reviews, testing, and continuous improvement processes.
• Prepare the engineering team to scale, including mentoring future hires.

Requirements:

• 3 to 5 years of professional software development experience.
• Strong command of at least one full technology stack (frontend + backend) with the ability to design scalable solutions.
• Knowledge of this stack: JavaScript/TypeScript, Node, Express/Hono, React/NextJs, Tailwind/CSS
• Intermediate-Advanced English (B2+)
• Experience in startups (software-first), YC backed, or big tech.
• Proven track record of applying best practices: testing, clean code, design patterns, documentation, CI/CD.
• Experience with relational and/or non-relational databases.
• Hands-on experience deploying applications to the cloud (AWS, GCP, Azure, or others).
• Solid experience with version control (Git) in collaborative environments.
• Builder mindset: passion for building, experimenting, and shipping fast.
• Strong communication skills and ability to thrive in a high-pace startup environment.

Nice to have:

• Previous experience in startups or as part of a founding engineering team.
