Senior Software Engineer Frontend

About TrueFoundry Every production AI system, whether it's powering customer support, writing code, analyzing financial data, or diagnosing medical conditions, needs the same foundational infrastructure.A way to route between models. A way to manage tools and integrate them securely. A way to orchestrate agents and enforce governance. A unified compute layer to run it all. That infrastructure layer is being built right now. We are looking for a Senior Software Engineer-Frontend to join the team. The Problem We're Solving Companies are moving beyond simple chatbots to production agentic systems. These systems route between OpenAI, Anthropic, Google, and self-hosted models. They integrate dozens of tools via protocols like MCP. They orchestrate multi-agent workflows where agents coordinate with other agents. The infrastructure to support this doesn't exist yet. You can't just duct-tape together a few API calls and call it production-ready. You need a control plane that handles: • Intelligent routing with observability, cost policies, and fallback logic • Centralized tool and MCP server management with security and lifecycle controls • Agent orchestration with governance and guardrails • A unified compute layer to run self-hosted models, custom tools, and agents AI Gateway is the control plane: five composable components (Prompts, LLM Gateway, MCP Gateway, Guardrails, Agent Gateway) that handle routing, orchestration, and governance. We're Series A, backed by Intel Capital and Sequoia. Companies like CVS, Mastercard, Siemens, Paytm, Synopsys, and Zscaler run production AI workloads on our platform. Responsibilities • Build, enhance, and maintain intuitive, high-performance front-end applications. • Collaborate with the design and backend teams to translate ideas into seamless user experiences. • Write clean, reusable, and well-documented code. • Optimize components for maximum speed and scalability. • Participate in code reviews, testing, and deployment processes. Requirements • 4–8 years of experience with strong proficiency in JavaScript (ES6+) and React.js. • Strong understanding of web fundamentals – HTML5, CSS3, DOM manipulation. • Experience with REST APIs and integrating front-end with back-end services. • Knowledge of modern build tools and version control (Webpack, Babel, Git). • Passion for building beautiful, responsive, and user-centric interfaces. Bonus Points • Experience with Next.js, TypeScript, or state management libraries (Redux, Recoil, Zustand). • Familiarity with UI/UX best practices and design systems. • Previous experience in a startup or fast-paced environment. Traits we are looking for: Ownership, ability to execute, hustle and think out of the box, data-driven decision making, be comfortable with more unknowns than knowns.
