Senior Software Engineer, Agent Experience (US)

Scrunch, a venture-backed startup, is on a mission to bring brands to an AI-first future—where people increasingly rely on LLMs to discover, understand, and act on information that matters to them.

As AI search and conversational agents replace traditional web search and browsing, Scrunch helps marketing teams rethink how their products and services are discovered and surfaced on AI platforms like ChatGPT, Claude, Gemini, and more—working with AI platforms, not against them. This shift represents the biggest change to marketing since the dawn of the internet.

With $26M in backing from Mayfield Fund, Decibel, Homebrew, GTM Capital, and leading Silicon Valley founders and operators, Scrunch has scaled rapidly since commercial launch. Today, more than 500 paying brands—including Fortune 500 companies like Lenovo, category-defining brands like Skims, and breakout startups like Clerk—use the platform.

We're looking for a full-stack senior software engineer to join our Agent Experience team. This is a high-ownership role that will deliver critical features & improvements end-to-end – from DevOps & platform selection all the way to tuning UI to feel "just right". Agent Experience builds platforms and products that become business-critical infrastructure for our customers, so if you want to build software for scale at a startup pace, this is a great role for you.
This role is open to candidates located in and legally authorized to work in the US. Scrunch is a remote organization, but in-office or hybrid work is possible for candidates based in the NYC or Salt Lake City metro areas (and we love to jam in person from time to time!)

For this role, we'd like to see candidates that:

• Have experience working in a high-velocity software development organization.

• Are proficient at building software that both powers and relies on the web -- real-time browser networking, optimizing proxies, scrapers, etc.

• Can build high-quality REST APIs (We use Python for APIs, but experience building APIs in TypeScript, Go, etc. is also OK.)

• Are proficient with relational databases and application-style SQL

  • Plenty of experience using an application database stack like ActiveRecord with Rails, Python SQLAlchemy, TypeScript Drizzle, etc.

  • Ability to write SQL by hand if needed, including joins and aggregations

• Are proficient writing unit tests and designing for testability.

• Experience with designing, building and operating cloud services, including configuring and integrating with things like application load balancers, cloud storage, and message queues.

Scrunch is an equal opportunity employer. We welcome people of all backgrounds, experiences, perspectives, and identities. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
