Position Summary & Responsibilities

Eulerity is a fast-growing marketing technology company transforming how franchises and small businesses approach digital advertising. Built by former leaders from Google, Facebook, and Yahoo!, our platform combines decades of experience in engineering and marketing to deliver an industry-leading, automated solution. We make it easy to plan, launch, and analyze paid campaigns across Google Search, Meta (Facebook/Instagram), Display, Video, and organic social - all from one intuitive platform. We believe breakthrough results happen when technology, strategy, and creativity come together. By combining automation with human insight, we empower brands to scale smarter, move faster, and grow stronger. Internally, we're just as committed to growth. We cultivate a culture where ambitious, curious, and driven individuals are empowered to lead, learn, and elevate those around them.

Your Role

Designing, building, and shipping developer-facing SDKs consumed by other engineers.
Owning the SDK as a product: the public API surface, TypeScript types, semantic versioning, packaging/distribution, backwards compatibility, and documentation.
Building and maintaining AI-powered automation workflows that connect our product to internal and external systems.
Developing and testing new features using AI-assisted tooling and autonomous agents, maintaining the codebase, integrating with APIs and data models, and owning the PR lifecycle (writing, reviewing, and incorporating feedback).
Collaborating across web, mobile, and backend teams to align on best practices, shared architecture, and product direction.
Partnering with Product and Design to translate designs and prototypes into shipped solutions for our users and the engineers who build on our SDK.

About You

SDK/library builder. You design clean, intuitive, hard-to-misuse APIs and think about the developer on the other side of your interface.
AI-first engineer. You've set up custom automation workflows (e.g., wiring Claude or similar LLMs into forms, APIs, or internal tools to replace manual work).
A self-starter who can take ownership of a project and work independently and collaboratively.
Rigorous about reviewing AI-generated output and taking full ownership of the code you ship.
Good attention to detail

Key Role Competencies & Evaluation Highlights

Key Role Focus:

Hyper-automation of digital marketing and agile SaaS scaling, testing your ability to simplify complex ad-tech operations for enterprise and franchise clients.

📋 Preparation Priorities (Key Areas to Clarify):

1. Relying on slow, enterprise-heavy, waterfall go-to-market strategies unsuited for a rapid ad-tech startup
2. Lack of hands-on technical understanding of digital marketing infrastructure and programmatic ad buying
3. Sounding like a traditional agency worker rather than a product-minded automation builder

✨ Recommended Role Alignment Hook:

I build automated martech infrastructure that slashes the friction of enterprise digital advertising across thousands of localized franchise locations.
