Key Skills for This Role
Full Job Posting
At Momentic, we’re building the future of quality.
We’re building the all-in-one quality platform powered by state of the art agents to help our customers ensure quality at every stage of the SDLC.
Top engineering teams at companies like Notion, Retool and Webflow use Momentic to ship high quality product. Millions of Momentic tests are executed every single day.
Our product has a very large problem space so there’s a ton of stuff to build and take ownership of - we’d be excited to get your help as we're hiring several extremely talented software engineers across the stack.
The product
The AI-native automated testing platform
Incredibly sticky. Our customers run us on every pull request and merge and before each deploy as quality gates
Leagues ahead of the status quo today (think Selenium/Cypress/Playwright)
Check out the demo video on our website .
About us
We’re a lean team of 17 (ex Robinhood, Retool, WeWork, Qualtrics, Assembled)
Located in-person San Francisco (650 5th St.)
Recent Series A raise of $15M led by Standard Capital, with participation from existing investors - Y Combinator, FCVC, and Transpose Platform.
You’re perfect for this role if…
You enjoy solving hard problems that have both product and technical ambiguity
You have strong engineering fundamentals, code efficiently, and you know what you're great at and what you're less great at
You dislike meetings and would much rather focus your time on building, being productive, and shipping code
You thrive when you have autonomy, own as many of the details as possible, and project manage your own work
You're in SF or you're willing to relocate, you love working in-person, and you're serious about joining us to build a culture we'll all love
