About Evertune AI

Evertune is building the first AI discovery platform for modern marketers. As large language models (LLMs) become the go-to source for recommendations – we help brands understand exactly what AI is saying about them, where they stand against competitors, and how to show up more often in AI-powered answers. Our platform turns black-box AI behavior into actionable insights, so marketing teams can make faster, smarter decisions that drive growth.

Founded by leaders who helped scale The Trade Desk into the world’s leading ad tech platform, we bring deep expertise in digital advertising, data, and high-growth environments. Now, we’re pioneering a new category at the intersection of AI, SEO, and brand strategy.

We raised a $15M Series A led by Felicis Ventures, with support from Eniac, NextView, Roger Ehrenberg, and leaders from OpenAI, Google, Meta, Uber, and more. This gives us the momentum to move faster and build the first enterprise-grade AI marketing suite.

Backed by top-tier VC investors and trusted by forward-thinking brands, we have the resources to scale – but what really defines us is our culture. We move fast, think boldly, and believe the best ideas win regardless of title. If you're excited about shaping the future of how brands grow in the age of AI, you’ll thrive here.

Your Team

You’ll join Evertune’s engineering team at a pivotal moment in the company’s growth. We’re a tight-knit, ambitious group building quickly at the frontier of AI and search, with teammates primarily based in New York and Seattle. We care deeply about craft, but we know great products are built through iteration – we value momentum, clear thinking, and people who turn ambiguity into product.

As an early member of the team, you’ll have a meaningful influence on what we build, how we build it, and how the engineering organization evolves as we scale. You’ll also play an important role in helping shape our engineering presence in New York - serving as a key on-the-ground leader for the team in our NYC office as we grow.

You must be based in the NYC area and available to work in-office with the team 3x/week at our Flatiron location.

Your Role

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 person will serve as a key engineering lead in NYC - helping create energy around the office, attract strong local talent, and partner closely on hiring as we build out the team

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.
