Software Engineer II AI - Brazil

Position: Software Engineer II AI Experiences - Brazil
Elastic, the Search AI Company, enables everyone to find the answers they need in real time, using all their data, at scale - unleashing the potential of businesses and people. The Elastic Search AI Platform, used by more than 50% of the Fortune 500, brings together the precision of search and the intelligence of AI to enable everyone to accelerate the results that matter.

By taking advantage of all structured and unstructured data - securing and protecting private information more effectively - Elastic's complete, cloud-based solutions for search, security, and observability help organizations deliver on the promise of AI.

What is

The Role

Rev Tech 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 Rev Tech's end user experiences.

* Lead the user experience of AI interactions. Partner with the principal engineer and Rev Ops 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 Open Telemetry 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 Rev Tech - or flag where Rev Tech'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.

What You Bring

We're looking for a frontend engineer with 3+ years of professional React and Type Script experience who is genuinely interested in how AI should show up in product interfaces - and has the instinct to recognize when it isn't working.

* React and Type Script. Comfortable building production-grade components and managing state in complex, data-rich interfaces.

* AI product curiosity. You use AI-powered tools, you have opinions about them, and you can articulate what makes an AI interaction useful versus noisy.

* Observability instinct.

Experience with instrumentation and frontend telemetry - Open Telemetry familiarity is a plus.

* Design collaboration. You feel confident distilling a design direction from stakeholders or a low-fidelity wireframe into front end components.

* Communication. 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.
