Software Engineer, Design Systems & Ai Tooling

Position OverviewWe are seeking energetic AI Design Engineers with 1-3 years of experience to help build, scale, and integrate the next generation of AI-powered developer tools, design systems, and data infrastructure.
Position OverviewWe are seeking energetic AI Design Engineers with 1-3 years of experience to help build, scale, and integrate the next generation of AI-powered developer tools, design systems, and data infrastructure.
In this role, you will be part of an agile engineering team using modern programming stacks and AI-assisted development tools to build high-performance backend services, interactive user workflows, and automated quality verification pipelines.
Our team is building an advanced design agent and Model Context Protocol (MCP) server that provides an AI-powered intelligence layer for enterprise development workflows. This platform grounds automated design decisions in standardized UI/UX guidelines and design system practices, ensuring AI-generated interfaces strictly adhere to established components, accessibility standards, content rules, and brand guidelines with consistent quality across web and mobile platforms.
Core Responsibilities (All Tracks)
Feature Implementation: Write clean, modular, and well-tested code in modern programming languages (e.G. TypeScript, Python).
AI-Assisted Engineering: Actively leverage modern AI coding assistants (e.G. GitHub Copilot) to accelerate development while applying strong Computer Science principles to ensure code correctness, security, and performance.
Agile Collaboration: Participate in agile sprint ceremonies, write unit and integration tests, and collaborate with product designers and senior engineers across business lines.
Enterprise Standards: Ensure all deliverables comply with enterprise security, data governance, and architectural standards.
Additional Focus Tracks ResponsibilitiesTrack 1: Backend Systems & Data Scalability
High-Performance Data Architecture: Design and optimize Postgres relational and JSON schemas, writing complex queries, indexes, and transactional boundaries to manage multi-dimensional design rule cascades.
Low-Latency Caching & Scalability: Implement distributed caching layers and invalidation mechanisms to guarantee low-latency data access under high concurrency.
Protocol & API Engineering: Build robust, streaming REST and Model Context Protocol (MCP) server endpoints to serve real-time design intelligence and tokens to connected developer tools.
Enterprise Security & Auth: Implement secure token validation, role-based access control (RBAC), and payload sanitization across all data pipelines.
Track 2: Fullstack & User Workflow Integration
Web Platform Development: Architect performant, responsive web applications and dashboards using React and modern TypeScript, managing complex client-side state and token visualization.
Figma Integration: Develop event-driven client features for our in-house Figma integrations, handling asynchronous canvas synchronization and bidirectional data serialization between design tools and backend servers.
Automated Code & Component Parsing: Write automated scripts to programmatically inspect modern design system component libraries, extracting property schemas and design tokens into structured MCP contracts.
Intelligent Code Adaptation: Develop surgical code-modification routines that allow AI agents to safely parse, update, and integrate new designs into existing application codebases without introducing syntax errors or breaking custom logic.
Track 3: Quality, Reliability & Verification Systems
Automated AI Verification Harnesses: Design and maintain automated testing engines and regression harnesses in Python or TypeScript to continuously evaluate the quality, compile rate, and accuracy of AI-generated code across web and mobile platforms.
Systematic Scenario Benchmarking: Maintain a comprehensive suite of standardized baseline test scenarios, systematically tracking compile success rates, design token compliance percentages, and response latency across releases.
Automated Compliance & Linters: Build automated linters that mathematically verify WCAG 2.1 AA accessibility (color contrast math, DOM focus states) and structural schema validity across all generated outputs.
CI/CD Quality Gates: Integrate automated verification suites into build and deployment pipelines to catch regressions, token drift, and syntax anomalies before features reach production teams.
Qualifications & Skill RequirementsBasic Qualifications:
Education: Bachelor's degree in Computer Science, Software Engineering, Human-Computer Interaction, or a related technical field.
Experience: 1-3 years of professional software development experience (or equivalent co-op, internship, or open-source project portfolio).
Programming Skills: Strong proficiency in modern languages: TypeScript/JavaScript, Python, SQL, Swift, or Kotlin
Foundational CS Knowledge: Solid grasp of core data structures, RESTful APIs, and relational database fundamentals.
Tooling & AI Fluency: Hands-on experience with Git version control and enthusiasm for using AI-assisted coding tools (e.G. GitHub Copilot, Devin AI) to maximize productivity.
Preferred Skills:
Familiarity with design systems concepts (e.G., design tokens, component architecture, style dictionaries, or Storybook).
Working familiarity with Figma as a user or developer (e.G., inspecting designs, Auto-Layout concepts, or exploring Figma APIs).
Experience with Postgres, SQL indexing, caching strategies, or building low-latency REST/MCP microservices.
Exposure to native mobile UI development (e.G., Swift / SwiftUI for iOS or Kotlin for Android) and mobile design token patterns.
Experience with automated testing frameworks (e.G. Playwright, PyTest) and CI/CD quality pipelines.
Familiarity with web accessibility standards (WCAG 2.1 AA, color contrast math, ARIA attributes, semantic HTML).
