The Role
Why Mintlify?

We're on a mission to empower builders.

  • Massive reach: Our docs platform serves 100 million+ developers every year and powers documentation for 10,000+ companies, including Anthropic, Cursor, PayPal, Coinbase, X, and over 20% of the last YC batch.

  • Small team, huge impact: We’re only 32 people today, backed by $22 million in funding, each new hire shapes the company’s trajectory.

  • Culture of slope over y-intercept: We value learning velocity, grit, and unapologetically unique personalities.

We grew in value faster than headcount and we’re looking to align the two quickly.

What you'll work on here
  • Backend software engineering & infrastructure engineering to support the AI and agentic flows

  • Owning and operating LLM-backed products in production at scale

  • RAG/data ingestion pipelines

  • Prompt engineering

  • Model performance and evals

What you bring to the table
  • You have 4+ years of software development experience

  • You possess deep customer empathy, and have the desire to speak with customers and make product decisions

  • You have a strong ability to learn new technologies and be productive in unfamiliar domains

  • You're passionate about tasteful user experience

  • Bonus points: You previously founded a startup. Extra bonus for a dev-tools startup

Why you should join our engineering team

Engineers at Mintlify appreciate a high degree of ownership, are passionate about a tasteful user experience, and come to work ready to contribute to a small-but-mighty team.

You’ll have plenty of heads down builder time. We believe in the power of strong teams to drive change - and have created an environment where the best ideas win and we can acknowledge when we’re wrong.

We’re all about finding the intersection between what excites you and business priorities. You’ll jump into new territory and learn something new. You’ll own projects and features. You’ll ship.
