Software Engineer, Frontend

Role Summary

About Tessera Labs Tessera Labs is redefining how enterprises adopt and operationalize Artificial Intelligence. Backed by Foundation Capital and led by a world-class founding team, we build multi-agent AI systems that can automate complex business workflows across platforms like SAP, Salesforce, Workday, Snowflake, MuleSoft, and more. Our mission: Bring real AI automation to the enterprise — with speed, precision, and measurable impact. We move fast, operate with extreme ownership, and build at the frontier of applied AI.

We are looking for a Frontend Engineer who thrives in a fast-paced, high-ownership startup environment. This is a hands-on role for a self-starter who can take ownership of the user experience from concept to deployment, iterate quickly based on feedback, and optimize for speed, usability, and performance. You will design and build sophisticated UI components, interactive dashboards, and data visualizations that directly impact end users.

If you love solving challenging UI problems, shipping polished interfaces at startup speed, and working in a collaborative, low-ego environment, this role is for you.

Responsibilities

• Rapid Feature Development & Deployment
• Build sophisticated data visualization interfaces, workflow management UIs, and real-time dashboards.
• Design and maintain scalable component libraries with consistent design patterns.
• Implement complex client-side state with optimistic updates and real-time synchronization.
• Create intuitive UIs for AI model interactions, data pipeline management, and enterprise system integrations.
• Optimize for speed, usability, and performance without compromising quality.
• Performance Optimization & Scalability
• Continuously identify and fix performance bottlenecks in frontend systems.
• Startup Mindset: Autonomy & Execution Speed
• Take initiative—identify problems and build solutions without waiting for direction.
• Make trade-offs between speed and long-term maintainability based on business needs.
• Work in a high-ownership environment, making architectural and UI design decisions as needed.
• Quickly adapt to changing priorities, tight deadlines, and startup pivots.

Requirements

• 3–5 years of Frontend development with advanced patterns (custom hooks, complex state management, performance optimization, client/server-side separation).
• Expertise in TypeScript (complex generics, utility types, strict typing in production applications).
• Strong experience with the modern React ecosystem (SSR -- TanStack Start, NextJS, data fetching and global state management libraries).
• Proven track record in enterprise UI development (component libraries, design systems, accessibility standards).
• Performance optimization skills (memoization strategies, render optimization, virtualization).
• Strong problem-solving skills and ability to execute quickly with minimal guidance.
• Experience working in agile, fast-paced startup teams.

Preferred Qualifications

• Experience with data visualization (charts, graphs, interactive dashboards).
• Real-time UI patterns (WebSocket integration, live updates, optimistic UI).
• Enterprise authentication (SSO, role-based access control, session management).
• Experience integrating AI/ML models into production applications.
• Familiarity with building developer-facing tools (code editor integrations, syntax highlighting, diff viewers).

No third party may recruit, solicit candidates, publish job opportunities, use Tessera Labs’ name or branding, or represent that they are acting on behalf of Tessera Labs without prior written authorization. Any such activity conducted without explicit written consent is strictly prohibited.

About the Company

ABOUT TESSERA LABS

Tessera Labs is a new category of enterprise software: an AI platform that changes how the world's largest companies run.

Every large enterprise carries the same weight — decades of accumulated process, data, and code that no longer match the business it has become. Changing any of it is a program measured in years and hundreds of millions of dollars, staffed by armies of consultants, and it fails more often than anyone admits. Most companies have quietly accepted this as the cost of being large.

We don't. Tessera is a transformation engine: a governed, multi-agent platform that understands an enterprise's process, data, and code as one connected system and changes it in weeks rather than years. We're vendor-agnostic by design — SAP, Salesforce, Workday, Oracle, Snowflake, MuleSoft — and tied to none of them.

Two things make this hard, and they're the reason the job is interesting. Governance: every action is logged, traceable, and reversible, because our customers are regulated and these are the systems that close their books. And generality: the platform has to work on landscapes it has never seen, at companies whose complexity is genuinely unique to them.

We sell a product, not a service. Our people are here to make the product successful, not the other way around. If you've watched enterprise AI companies quietly become consultancies, that distinction is the one to press us on.
