ABOUT DESCRIAL

Descrial is an AI work-execution platform purpose-built for alternative investment firms and their portfolio companies and securely orchestrates proprietary data, external sources, and workflows. Descrial is an important pillar of Enterprise Intelligence Orchestration (EIO) and enables it by structuring and standardizing data while embedding domain expertise, thereby enabling faster and contextual analysis, broader coverage, and more intelligent decision-making. It is backed by TresVista's 1,800+ employees and deep domain expertise across investment diligence, research, valuation, fund administration, accounting, and data analytics. The team is small, senior, high-ownership, and in-office, with direct access to the Executive Committee.

OVERVIEW

As a Front-End Engineer on the UK core team, you will build the interfaces investment professionals live in: data-dense dashboards, document-centric workflows, and AI-assisted experiences where trust and verifiability are part of the design. The stack is React and React Native with TypeScript, a shared component system themable across tenants, and the performance discipline that data-heavy enterprise UI demands.

ROLES AND RESPONSIBILITIES

Product engineering

• Build complex product surfaces in React / React Native with TypeScript: advanced forms, analytics dashboards, real-time updates, and rich document views
• Build data-dense experiences properly: grid components (AG Grid / MUI DataGrid class), virtualisation, CSS Grid/Flexbox layouts that hold at scale
• Implement AI-experience patterns: streaming responses, citation and verification affordances, and graceful failure states for model-backed features
• Design the interface for agentic workflows: approval and hand-off steps, visibility of what a tool call is doing, partial-progress states, and letting a user interrupt or correct an agent mid-run
• Make model-backed interactions feel responsive: perceived-performance work for calls that take seconds rather than milliseconds

Platform and quality

• Contribute to the shared component library and multi-tenant theming system; keep per-tenant branding, permissions, and configuration clean
• Integrate securely with backend APIs: auth, role-based access, tenant context, and client-side error handling
• Write and maintain unit, integration, and E2E tests (Jest, React Testing Library, Cypress/Playwright); meet accessibility standards (WCAG 2.1)
• Profile and optimise: code splitting, lazy loading, memoisation, bundle discipline through Jenkins + SonarQube pipelines to AWS

WHO YOU ARE

Prerequisites

• 5+ years of front-end engineering with deep React and TypeScript; React Native experience valued
• Proven work on data-dense, enterprise-grade UI — grids, dashboards, complex state
• Strong grasp of state management patterns, front-end security (XSS, CSRF, CSP), and testing discipline
• SaaS/multi-tenant product experience; Git, CI/CD, and cloud deployment familiarity
• You build with AI coding tools daily (Cursor, Claude Code or comparable) and have a considered view of where they help and where they do not

• Design-system contribution or ownership
