Software Engineer II AI Experiences
ElasticSelf-described as the leading platform for search-powered solutions, Elastic helps organizations, their customers, and their employees find what they need faster while protecting a
Role Description RevTech Engineering builds the tools Elastic's Field teams depend on every day — the conversational experiences, single-pane-of-glass portals, and AI-powered workflows that help sellers, solutions architects, customer success managers, and support teams do their best work. The AI Experiences squad is where those AI capabilities take shape in the UI. We're looking for a Software Engineer II who is as curious about how AI behaves in a product as they are about how to build it. This role isn't about training models or writing pipelines — it's about making AI interactions legible, useful, and trustworthy for the people using them. You'll work closely with a principal software engineer who brings both design and engineering depth, which means you'll have real mentorship and a high bar to grow toward. You'll also be connected to what's happening across Elastic's broader AI and design system work, contributing to consistent surfaces and bringing back patterns that raise the quality of what we ship. What You Will Be Doing - Build AI components for Field-facing experiences. - Develop and iterate on the front end components that surface AI capabilities — tool calling, reasoning traces, generative responses, suggestions — across RevTech's end user experiences. - Lead the user experience of AI interactions. - Partner with the principal engineer and RevOps team members to evaluate whether AI components are working — is the right information surfaced, is the response legible, is tool-calling output helping or overloading the user? - Instrument what you build. - Use OpenTelemetry to instrument AI components so the team has a signal on what's working. Track interaction patterns, identify friction points, and use that data to drive iteration. - Contribute to AI UI consistency. - Stay ahead of how Elastic UI and the broader Elastic AI product surface handle AI components, and apply those patterns in RevTech — or flag where RevTech's needs require something new. - Support the Salesforce LWC surface. - Contribute occasionally to AI component work in Elastic's Salesforce Lightning Web Component environment for AE/SDR workflows. Qualifications - 3+ years of professional React and TypeScript experience. - Genuine interest in how AI should show up in product interfaces. - Instinct to recognize when AI interactions aren't working. Requirements - Comfortable building production-grade components and managing state in complex, data-rich interfaces. - Experience with instrumentation and frontend telemetry — OpenTelemetry familiarity is a plus. - Confidence in distilling a design direction from stakeholders or a low-fidelity wireframe into front end components. - Comfortable working directly with field stakeholders to understand how AI components land in real workflows. Bonus Points - Familiarity with Elastic UI (EUI) or experience working within a mature design system. - Figma or other design tool experience. - Experience building or iterating on AI-specific UI patterns — streaming responses, confidence indicators, tool-calling displays, citation surfaces. Benefits - Competitive pay based on the work you do here and not your previous salary. - Health coverage for you and your family in many locations. - Ability to craft your calendar with flexible locations and schedules for many roles. - Generous number of vacation days each year. - We match up to $2000 (or local currency equivalent) for financial donations and service. - Up to 40 hours each year to use toward volunteer projects you love. - Minimum of 16 weeks of parental leave.

We expect all team members to actively engage with AI tools relevant to their role and grow their fluency as the technology evolves. AI experience requirements vary by role and will be assessed during the interview process. About the Role: As a Staff Engineer on the Developer Productivity - AI Developer Tools team, you will be the architectural anchor shaping the AI platform that accelerates engineering across Gusto. You will redefine how our entire engineering organization builds, tests, and ships software by architecting a highly secure, context-aware, "AI-native" development lifecycle. Your mission is to eliminate developer friction through AI tools, multi-agent systems, and intelligent automation. Whether you are building bespoke internal coding assistants, automating sprawling codebase refactors, or deploying AI to self-heal CI/CD pipelines, your work will directly multiply the velocity of hundreds of builders. Help us drive developer productivity by building the next generation of AI tools. About the Team: The AI Developer Tools team is a specialized team within Developer Productivity. We believe AI is the next great leap in software craftsmanship. Our goal is to provide every builder at Gusto with a suite of "superpowers" tools that deeply understand our codebase and absorb operational toil so engineers can focus on creative problem-solving. We treat our fellow engineers as our primary customers, prioritizing developer experiences that are not just powerful, but absolutely delightful to use. Here’s what you’ll do day-to-day: - Architect AI Core Infrastructure: Design, scale, and maintain the internal platform and APIs that integrate LLMs into the developer workflow, with a heavy focus on autonomous agents, custom retrieval-augmented generation (RAG), and smart context-delivery systems. - Drive Technical Leadership & Vision: Establish engineering best practices for building with AI at Gusto, including robust evaluation frameworks (evals), guardrails for code safety, and strategies for optimizing model latency and token spend. - Collaborate & Evangelize: Partner closely with product engineering teams to uncover systemic friction points, and collaborate with core Infrastructure and Security teams to ensure all AI tooling is scalable, compliant, and secure. - Optimize Feedback Loops: Identify and eliminate critical bottlenecks in the local-to-production lifecycle at scale across Gusto. - Maintain Enterprise Reliability: Treat AI infrastructure with production-grade rigor. Monitor system health, diagnose complex integration or networking issues, and mitigate model drift or downtime. Here’s what we're looking for: - 8+ Years of Systems Expertise: You are a seasoned engineer who is highly comfortable navigating massive, complex codebases and delivering production-grade, distributed software. - Production AI Experience: You have a proven track record of moving AI beyond prototypes. You possess a deep understanding of prompt engineering, fine-tuning, RAG architectures, and orchestrating multi-agent workflows. - Developer-First Mindset: You are passionate about Developer Experience and Productivity. You intuitively understand what makes an internal tool frictionless, fast, and empowering for other engineers. - Strategic Execution: You don't just build wrappers; you think deeply about data privacy, security, cost management, and systemic reliability when deploying AI solutions. - Exceptional Communication: You can seamlessly translate bleeding-edge AI capabilities into clear, actionable infrastructure strategies, mentoring junior engineers and aligning cross-functional stakeholders along the way. - Working as a Team: You work across team boundaries and bring other teams and groups along with you towards our strategic vision. Our cash compensation amount for this role is targeted at $180,000/yr to $200,000/yr in Denver & most remote locations, $220,000/yr to $245,000/yr for San Francisco, New York & Seattle. Stock equity is additional. Final offer amounts are determined by multiple factors including candidate experience and expertise and may vary from the amounts listed above. Gusto has physical office spaces in Denver, San Francisco, and New York City. Employees who are based in those locations will be expected to work from the office on designated days approximately 2-3 days per week (or more depending on role). The same office expectations apply to all Symmetry roles, Gusto's subsidiary, whose physical office is in Scottsdale. Note: The San Francisco office expectations encompass both the San Francisco and San Jose metro areas.
