Founding Frontend Engineer

## About this role We are hiring our Founding Frontend Engineer on a four-month contract from Month 2 through end of Month 5. You will take the architect's UX specifications and the Backend Engineer's OpenAPI 3.0 specifications and build the customer-facing Acrivault dashboard — the V0.1 product that design partners will use from Month 6 onward. This is a contract role for the V0.1 build. Conversion to full-time is possible but not guaranteed at the end of the contract; it depends on the Frontend Engineer's performance, the company's hiring sequence, and the funding state at that point. Strong contractors will be the first candidates considered for the full-time Frontend Lead role planned for Month 7-9. ## What you'll build You will build the five module dashboards aligned to the v2 AI-Native architecture (the five engineering pillars), the authentication flow, and the responsive layouts that work on laptops and tablets. The stack is React 18 with TypeScript, Tailwind CSS, React Query, Recharts, and Storybook. - Module 1 — Discover: the NHI inventory table (sortable, filterable, paginated), the risk-score badge, the per-NHI drill-down (attributes, relationships, recent activity). - Module 2 — Govern: the policy authoring UI (rule builder, approval workflows, policy bundle versioning), the privilege-drift dashboard. - Module 3 — Monitor: the real-time behavioral scoring view, the alert feed (LLM-summarized), the per-tenant SLO dashboard. - Module 4 — Rotate: rotation job queues, rotation schedule configuration, rotation history with audit trail, one-click emergency rotate-all. - Module 5 — AI Intelligence (new in v2): the agent session replay viewer (timeline of prompts, tool calls, credentials used, model responses, tool outputs), the AI Bill of Materials browser (LLMs, versions, fine-tuning lineage, training data sources, MCP servers, prompt templates graphed against the NHIs that consume them), the prompt-injection alert feed, similar-incident search powered by the vector store. Read-only in V0.1 — this is the 3 am incident-response replay demo that wins customers. - Authentication flow: login, SSO, MFA, per-tenant SSO configuration wizard for design partners. - The Storybook component library that becomes Acrivault's frontend design system. ## Required qualifications - 5+ years of production frontend engineering, with deep fluency in React 18+, TypeScript (strict mode), Tailwind CSS, and React Query (TanStack Query). - Direct experience building data-dense SaaS dashboards: sortable/filterable/paginated tables at 10,000+ row scale, real-time data streaming, time-series visualizations with Recharts or D3. - Production experience with OpenAPI 3.0 contracts (generating clients from specs, handling streaming endpoints, working with backend engineers on contract design). - Strong product sensibility. You can read a Figma spec and tell the designer where the interaction model breaks at scale. You push back on UX that would not work for an enterprise security
