About The Position

You will own everything the user sees and touches in Peach Pilot. This is the most important engineering surface in the company. Our users are CEOs, operations leaders, and business professionals. They have never used a terminal, don’t know what an API is, and are skeptical about AI. Your job is to make them trust it. We call this the “Waymo Moment.” The experience of getting into an autonomous vehicle, being nervous, and five minutes later feeling completely at ease because everything just works. That is what you are building. Every interaction, every screen, every transition needs to earn trust and feel effortless. If the interface creates even a moment of doubt, the AI behind it doesn’t matter. This is a senior, full-stack role with heavy emphasis on the front-end and user experience layer. You will also integrate third-party tools and libraries to deliver rich document visualization, interactive dashboards, mini-app generation, and seamless file handling, all behind a conversational interface that hides the complexity. You are the front-end team, the UX thinker, and the integration engineer, all in one. You obsess over the details that non-technical users notice: loading speed, button placement, copy, transitions, micro-interactions. You know that trust is built in the small things. You have built products that your parents could use. You understand that “easy to use” is the hardest thing to engineer. And you think about how the AI should communicate, not just what it says, but how it appears, how it loads, how it handles uncertainty. You are building the AI’s body language. This is a ground-floor opportunity. You will be one of the first engineers on the team, and your fingerprints will be on everything users touch.

Requirements

7+ years of software engineering experience with significant full-stack work and deep expertise on the front-end.
Expert-level front-end development. React (or Next.js/Vue), TypeScript, modern CSS/Tailwind. You build polished, consumer-grade interfaces, not developer tools.
Deep experience building for non-technical users. You have shipped products where trust, clarity, and ease of use were the primary engineering challenges. You know that progressive disclosure, graceful error handling, loading states, and accessibility are not nice-to-haves.
Track record integrating third-party libraries and tools into cohesive product experiences. You know when to build vs. buy and how to stitch components into something seamless.
Experience with real-time UI. WebSockets, Server-Sent Events, optimistic rendering. You have built interfaces that update live as data flows in.
Experience working with AI/LLM APIs. You have built interfaces that present AI output elegantly, handle streaming responses, and manage the UX of uncertainty and latency.
Backend proficiency. Python and/or Node.js/TypeScript for API development. You can build the endpoints your front-end needs, not just consume them.
Cloud infrastructure experience. Azure preferred, AWS acceptable.

Nice To Haves

Experience building AI-powered products where trust and transparency are core to the UX.
Experience with document processing and rendering in the browser (PDF, Office formats, charting).
Deep experience with data visualization libraries (D3, Plotly, Chart.js, Recharts).
Experience with document generation pipelines (creating Word, PDF, PowerPoint programmatically).
Experience with design systems and component libraries at scale.
Background in human-computer interaction (HCI) principles or behavioral design.
Familiarity with enterprise software requirements (SSO, RBAC, audit logging, multi-tenancy).
Experience with graph databases (Neo4j) and knowledge graph visualization.
Familiarity with the Microsoft Azure ecosystem (Azure AD, Cosmos DB, Azure Functions).
Experience at an early-stage startup, comfortable with ambiguity and owning large surface areas.

Responsibilities

Build the Trust Layer (The User-Facing Platform Experience)
Own the entire user-facing interface: chat, document viewer, dashboards, onboarding flows. Build the side-by-side layout with conversational AI on the left and rich document/report preview on the right.
Design and implement progressive disclosure. The system reveals capability gradually, never overwhelming the user. The first five minutes of a new user’s journey must be guided, conversational, and zero friction. Start simple, prove value, expand capability.
Build proactive trust signals into every interaction. Confidence scores, validation badges, “show your work” panels that build trust through transparency. Error handling that maintains trust: when something goes wrong, the UI communicates clearly and recovers gracefully.
Create the adaptive onboarding experience. Personalized based on the user’s role, industry, and comfort level. Channel setup integration across Teams, Telegram, Slack, and email.
Document Visualization & Editing
Build rich in-browser rendering for Word, Excel, PowerPoint, PDF, images, and diagrams. Integrate third-party document processing and rendering libraries (PDF.js, SheetJS, Reveal.js, Mermaid, or similar) into a cohesive experience.
Implement chat-driven editing: user describes changes in conversation, preview updates in real time. Version history with visual diffs. One-click export pipeline generating .docx, .pdf, .xlsx, .pptx from platform content.
Interactive Dashboards & Data Visualization
Integrate professional charting libraries (Plotly, Chart.js, D3, Recharts, or similar) with interactive features: hover, filter, drill-down, all generated from natural language requests.
Build data validation UI: inline confidence indicators, flagged discrepancies, approval workflows. Saved dashboards with scheduled delivery.
Mini-App Generation & Templates
Build the framework for generating lightweight interactive applications from conversational prompts: CRM trackers, event RSVP forms, data entry tools, status dashboards. Plug-in architecture for third-party components and widgets.
Build the template management system for legal docs, reports, and business documents. Company branding engine that automatically applies client colors, logos, and fonts to all generated output. Template versioning and admin management.
File & Data Handling
Own the file pipeline end to end. Drag-and-drop ingestion of Excel, CSV, PDF, and images. File format detection and intelligent routing to appropriate processing and rendering engines. Cloud storage integration with OneDrive, Google Drive, and SharePoint. Secure file handling with encryption, access control, and audit trails on every interaction.
