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](https://momentic.ai/). ## 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 Must-have qualifications - Experience with LLM performance tuning, including prompt engineering and context management strategies - Experience with LLM evaluations and observability - Experience integrating LLMs into real-world applications using a modern tech stack (Python, TypeScript, etc.) - Familiarity and experience with supervised fine-tuning (SFT) and/or reinforcement learning fine tuning (RLFT) on platforms such as fireworks, Together AI, or Baseten - Familiarity with evaluation dataset engineering, prompt engineering, LLM as a judge verifiers, and RL environments - 3+ years of experience ## Nice to have - Experience with supervised or reinforced fine-tuning - Experience with classical machine learning techniques such as template matching, bounding box detection, and OCR - Experience running statistical experiments ## Our stack React, TypeScript, Next.js, Node.js, PostgreSQL, Google Cloud, Kubernetes ## Benefits - Competitive Medical, Vision, Dental insurance - 401K - Unlimited PTO - Offsites and events (Lake Tahoe this year!) - Fully stocked kitchen Sponsorship We can't sponsor/transfer H1B Visas or Green Cards (I-140) at this time. ## About Momentic ## Company Overview - **One-liner**: Momentic is an AI-native testing platform that enables engineering teams to write, run, and maintain end-to-end tests for web and mobile in plain English, using AI agents to automatically triage failures and heal tests as products evolve. - **Entity Type**: Private (Series A) - **Headquarters**: San Francisco, California, USA - **Founded**: 2023 - **Founders**: Wei-Wei Wu (Co-founder & CEO), Jeff An (Co-founder) ## Core Business - **Primary industry/industries**: Software Testing & QA, Developer Tools, AI-Powered Automation - **Target customers**: B2B, primarily aimed at engineering teams building web and mobile applications (ranges from startups to large enterprises) - **Mission or purpose statement**: To build the definitive verification layer for software, eliminating the QA bottleneck and catching real bugs before they ship ## Products & Services - **Momentic Platform (AI-Native End-to-End Testing)**: A SaaS platform where tests are authored in human-readable YAML (plain English). The platform uses AI agents to auto-heal tests as UI changes, triage failures with root cause analysis, map user flows to find coverage gaps, and generate tests from pull requests and diffs. Supports web, mobile (iOS/Android), and runs in CI/CD pipelines. - **Momentic for Mobile**: Extends the platform to native iOS and Android with failure recovery and dedicated mobile editing. - **Enterprise Features**: SOC 2 Type 2 compliance, 99.99% uptime SLA, SSO (SAML), RBAC, dedicated Customer Success Manager, 24/7 support. - **Self-Healing Specs**: Automatically adapts tests to UI changes, flagging only genuine regressions. ## Market Standing - **Valuation/Market Cap**: Not disclosed - **Key Metrics**: Total funding of **$19.2M** with **$15M** raised in a Series A round led by Standard Capital on November 24, 2025. The company reports over **70 million test runs executed**, over **8.9 million auto-heals**, and **117,010 bugs caught** before production. Has a **96% signal-to-noise ratio**. - **Notable Investors/Partners**: Standard Capital (Lead, Series A), Dropbox Ventures, Y Combinator (Batch W24), FCVC, Transpose Platform, Karman Ventures. - **Growth Signals**: Post-Series A funding to accelerate product and mission; used by 100+ teams including Notion, Bilt, Quora, Xero, and Webflow; rapid adoption driven by the AI coding boom (GitHub Copilot, Cursor) which creates testing bottlenecks. ## Competitive Advantages - **AI-First Design**: Unlike traditional testing frameworks (Selenium, Cypress, Playwright), Momentic is built from scratch around LLMs and agents to autonomously write, run, and maintain tests without manual scripting or XPath/CSS maintenance. - **Auto-Healing at Scale**: With millions of auto-heals performed, the platform actively learns the product's UI, terminology, and user flows from codebases, docs, and tickets to reduce flaky tests. - **Agentic Triage**: Provides root cause analysis, session replays, and reproducible steps for failures, connecting failures to codebase context. This reduces debugging time for engineering teams. - **Low Maintenance Overhead**: Tests are self-maintaining and adapt to changes, freeing QA and engineering teams from babysitting test suites. ## Strategic Focus - **Scale the Verification Layer**: Momentic is focused on becoming the essential quality infrastructure for the age of AI-generated code. As coding velocity increases, the company aims to prevent a quality collapse by providing an automated, intelligent testing layer. - **Deepening AI Integration**: The platform continues to expand its AI agents to learn from more tools (Jira, Linear, Figma) and close coverage gaps automatically. - **Enterprise Adoption**: With strong compliance (SOC 2, SLA) and dedicated support, Momentic is targeting larger enterprise accounts that need reliability and control. ## Why Work Here - **Culture Highlights**: Momentic is a Y Combinator-backed startup (W24) with a mission to solve a high-impact problem that is becoming critical in the AI era. The team is small (approximately 15 people) and focused on deep technical work. - **Remote/Hybrid/Office Policy**: HQ is in San Francisco (177 Townsend Street, Unit 930). The specific remote policy is not detailed publicly, but the operational setup (in-office for HQ, but tooling supports CI/CD globally) suggests a hybrid or flexible environment is likely. - **Notable Perks or Engineering Culture**: High-autonomy engineering environment (“Agents are shipping software faster than QA can keep up”). The company offers competitive compensation for a Series A startup (e.g., salary ranges from $150K - $220K listed on YC jobs), and equity. The work involves cutting-edge AI and LLM applications in a real-world product that tens of thousands of developers use. ## Sources 1. [momentic.ai](https://momentic.ai/) 2.
