Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Software Engineering SMTS - **Company:** Salesforce.com, Inc. - **Location:** Bellevue, WA, United States - **Salary:** $148,500.0 - $223,900.0 - **Contract:** Permanent contract - **Skills:** JavaScript (Programming Language), Artificial Intelligence, Code Review, Software Debugging, Software Engineering, TypeScript, Large Language Models, Backend, Playwright, Front End Software Development - **Published:** September 12, 2026 - **Apply:** https://diversityjobs.com/main/sendform/8/8/28176/1/18255580?backUrl=%2Fcareer%2F18255580%2FSoftware-Engineering-Smts-Washington-Bellevue ## About the Role * You have experience building browser automation with Playwright or comparable tools. * You can trace difficult failures across browser behavior, frontend state, and backend services. * You can design tests that distinguish reliable behavior from something that happened to work once. * You want to work directly with customers, investigate unfamiliar applications, and turn what you learn into product improvements. * You use AI development tools thoughtfully and take responsibility for the correctness, security, and maintainability of what you ship. Helpful Experience * Browser extensions, accessibility trees, resilient element targeting, or recording and replay systems. * LLM-powered applications or computer-use agents. * Building an early-stage product or working in a customer-facing engineering role. ## Description You'll join a team that builds directly with customers. Your browser expertise will shape what this product can accomplish, and you'll own capabilities from initial design through production use. What You'll Actually Be Doing Drive Browser Automation & Architecture * Build browser-extension capabilities that capture user interactions and the context needed to reproduce workflows reliably. * Develop automation for complex applications, including dynamic pages, nested frames, custom controls, and asynchronous state changes. * Improve how agents understand page structure, identify controls, execute actions, and recover when interfaces change. * Create debugging and replay tools that make automation failures easier to understand and resolve. * Extend the product experience so customers can record workflows, monitor execution, and inspect results. Build Directly With Customers * Observe how customers use their applications and identify the interactions and state changes automation needs to capture. * Investigate failures in customer environments, tracing problems through browser behavior, application state, and execution services. * Turn application-specific discoveries into reusable recording, targeting, and recovery capabilities. * Help customers record and troubleshoot workflows independently, using their experience to improve the product. Shape Technical Direction & Grow the Team * Own architectural decisions for browser recording and execution, including recording fidelity, element targeting, and browser state. * Partner with AI engineers to define the observations and actions agents need to operate applications reliably. * Mentor peers through design discussions and code reviews, and participate in hiring. You're Our Person If... * You've independently owned a significant web capability or system through design, deployment, production failures, and subsequent improvements. * You have strong JavaScript or TypeScript skills and a deep understanding of the DOM, browser events, network behavior, and asynchronous execution. ## Related Videos - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Do TypeScript without TypeScript](https://www.wearedevelopers.com/videos/327-do-typescript-without-typescript) - [But, you're not Facebook](https://www.wearedevelopers.com/videos/378-but-you-re-not-facebook) - [Are Classical Automation Frameworks Dead?
