react for AI agent platforms

Acclaim AI develops AI products for technology corporations, including devices and voice assistants. Its technology stack covers speech technologies, NLP, generative AI, voice-first agentic architecture, privacy-first solutions, and on-premises deployment.

• Build and evolve React interfaces for an AI agent platform, including conversation and prompt engineering tools, graph-based collaborative flow builders, agent configuration and testing interfaces, and call analytics dashboards based on Figma designs;
• Own and develop the BFF layer on NestJS, aggregating REST microservices through typed clients generated from OpenAPI;
• Handle authentication, pagination, streaming, and error contracts to keep the frontend layer thin;
• Contribute to backend development with PostgreSQL and Redis;
• Drive the evolution and consistency of the frontend component ecosystem;
• Consolidate legacy Ant Design components into a design system built on Mantine;
• Own the shared UI library and Storybook and keep multiple product applications consistent;
• Ensure product quality through comprehensive testing with Vitest and Playwright, including SDK functionality;
• Collaborate across teams and product v-teams on API contracts, SDK protocols, code reviews, bug fixes, QA support, and test scenarios;
• Join initiatives where frontend or platform expertise is needed;
• Partner with the documentation team to create and maintain comprehensive documentation, including integration guides and practical code examples.

• 6+ Years of professional experience in frontend or full-stack product development;
• 5+ Years of React experience in production;
• Senior-level expertise in TypeScript, including strict mode, React 19, Vite, and monorepos;
• 2+ Years of Node.js development on the server;
• Hands-on experience building and operating BFF or API gateway layers;
• Understanding of service aggregation, authentication, pagination, error contracts, and clear BFF boundaries;
• Strong production experience in microservice environments, ideally with 10+ services;
• Experience building complex, stateful UIs such as graph/canvas editors or collaborative interfaces;
• Strong frontend architecture and code organization skills, including FSD or modular/layered architectures;
• Ability to work within an established team architecture;
• Strong product sense and autonomy in making UI and UX decisions from product context and an existing design system;
• Hands-on experience writing and maintaining unit/component tests with Vitest and end-to-end tests with Playwright;
• Hands-on experience with React Query, Socket.io, Prisma, and PostgreSQL;
• Experience with AI-assisted development tools such as Claude Code, Cursor, Codex, GitHub Copilot, or similar agentic coding tools;
• Ability to assess where AI agents add value and where they require human oversight;
• Experience working with development workflows that integrate agent instructions and automated reviews into the repository or CI;
• Nice to have: Experience owning or maintaining a shared component library used by multiple product teams, migrating a legacy UI to a new design system, real-time collaboration technologies such as Yjs, Automerge, or operational transforms, WebRTC or SIP in the browser, Prisma or Kysely and PostgreSQL query optimization, Kubernetes/Helm, OpenTelemetry or Prometheus, domain experience in voice AI, telephony, contact centers, conversational AI, or LLM-based products.

• The team has built award-winning AI products for technology corporations, including devices and voice assistants;
• Cutting-edge technology stack covering Speech Technologies, NLP, Generative AI, voice-first agentic architecture, privacy-first solutions, and on-premises deployment;
• High engineering standards and real ownership with direct production impact;
• Fast career progression in a senior-heavy team with a high volume of real problems;
• Startup pace with enterprise stability, real clients, real revenue, and no bureaucracy;
