About The Position

As a Lead Full Stack Engineer at Evertune, you’ll help shape the future of how marketers interact with AI. This is a hands-on player/coach role for someone who thrives at the intersection of product, engineering, and execution - someone who can build across the stack, lead by example, and help raise the bar for a growing team. You’ll contribute directly to core product development while helping provide technical leadership for engineers around you, especially more junior team members in New York. We’re looking for someone who brings strong ownership, sound judgment, and mentorship instincts – someone who has led, influenced technical direction, and helped others grow. This role is ideal for an engineer who wants to remain deeply hands-on while also helping create structure, clarity, and momentum across a fast-moving product and engineering organization. You should be excited by AI-native product experiences, energized by ambiguity, and already heavily using AI tools and LLMs in your own workflow to operate with greater leverage.

Must be AI-forward and actively using AI tools / LLMs to increase leverage and engineering efficiency
Excellent communication and collaboration skills, especially in cross-functional settings with design, product, and business stakeholders
