S23 - Hot Job

Role, Fullstack Engineer

Salary, $150,000, $180,000

Location, New York (Hybrid)

About the Role

A well funded, fast growing B2B SaaS company is hiring a Fullstack Engineer to help build and scale its core platform used across live operational environments.

This role sits at the intersection of software, infrastructure, and real world systems. The platform integrates with multiple third party technologies, physical access systems, and operational tools, meaning reliability and clean engineering matter just as much as feature delivery.

You'll join a small, senior engineering team where engineers own problems end to end rather than being restricted to frontend or backend silos.

This is ideal for someone who enjoys solving complex integration challenges, working across the full stack, and shipping software that operates in real world environments, not just browsers.
