Senior Frontend Engineer - Toulouse (M/F)

The Challenge: Building the “Gold Standard” for Private Equity

Private Equity is the last frontier of finance still running on Excel and fragmented processes. At Roundtable, we are building the infrastructure that allows thousands of investors to co-invest with surgical precision.

You’ll join a 10-engineer senior full-stack team organized in 2 squads, and you’ll be part of opening a third one. You’ll work closely with 2 product managers and be directly supported by our CTO and CPO, both founders.

Your Mission

You won’t be one frontend engineer among many. You’ll be the frontend expert,the person who sets the standard, owns the architecture, and shapes how we build.

• Design System Ownership: Own and evolve our token-based design system: components, accessibility, theming, documentation. You set the direction and raise the bar for the whole team.

• React & Next.js Engineering: Define the right patterns for RSC, caching, state management, and performance. Opinionated, pragmatic, and built to last.

• Performance & Real-Time Interfaces: You’re the guardian of frontend performance, Web Vitals, bundle size, rendering strategies. You’ll build high-performance investor dashboards with real-time data, and make sure speed is never an afterthought.

• Product Thinking: You don’t just implement specs, you engage with the product logic behind them. You ask why, spot inconsistencies early, and help shape what gets built, not just how.

• Integration Automation: Explore and experiment with LLM-assisted workflows to eliminate repetitive integration work, and redirect that effort toward higher-value engineering.

• Design Collaboration: Work directly with our freelance designers. Translate Figma into pixel-perfect components, and push back when something won’t scale.

• End-to-End Initiative: At Roundtable, we encourage engineers to follow problems wherever they lead. If you spot something worth improving in the backend, logic, API layers, data flow, you’re welcome to dig in. Ownership matters more than boundaries.

Core Stack

• Core: Next.js (App Router) with React Server Components, 100% TypeScript (strict mode, no any).

• Styling: Tailwind CSS with custom design tokens, Shadcn/Radix/Base UI for accessible, composable components.

• API & Communication: Migrating from GraphQL (Apollo Client) to tRPC with Zod for end-to-end type safety.

• Quality: Vitest, Playwright, Storybook, Zod

• Observability: Datadog (browser + server), PostHog.
