Job description

DevRev

DevRev’s AgentOS, purpose-built for SaaS companies, comprises three modern CRM apps for support, product, and growth teams. It connects end users, sellers, support, product people, and developers, reducing 9 business apps and converging 6 teams onto a common platform.

Unlike horizontal CRMs, DevRev takes a blank canvas approach to collaboration, AI, and analytics, enabling SaaS companies to increase product velocity and reduce customer churn. DevRev is used by thousands of companies in search of low latency analytics and customizable LLMs to thrive in this era of GenAI.

Headquartered in Palo Alto, California, DevRev has offices in seven global locations. We have raised $100 million in funding from investors like Khosla Ventures and Mayfield at a $1.1 billion valuation. We are also honored to be named on the Forbes 2024 list of America’s Best Startup Employers. Founded in October 2020 by Dheeraj Pandey, former co-founder and CEO of Nutanix, and Manoj Agarwal, former SVP of Engineering at Nutanix, DevRev continues to push the boundaries of innovation, helping thousands of companies thrive in the rapidly evolving landscape of AI-driven SaaS.

Senior Frontend Engineer

Shape the craft, architecture, and developer experience of an AI‑native, data‑driven platform.

Why DevRev?

Over the last few years we have:

• Pushed browser limits with D3‑powered visualizations and real‑time dashboards.
• Open‑sourced client‑side analytics on DuckDB, bringing OLAP to the edge.
• Designed data‑driven, AI‑native UIs that feel fast, intelligent, and downright fun.
• Scaled & themeable design systems adopted across multiple products and platforms.
• Introduced micro‑frontends that power independent, high‑velocity feature teams—and let customers embed their own modules directly inside DevRev, tailoring the product to their workflows.
• Embedded deeply configurable, data‑driven UIs - layouts, components, and visualizations can be reshaped end‑to‑end via declarative configuration.

…and we’re just getting started. If you care deeply about craftsmanship, modular UI architecture, and world‑class developer experience, this is your playground.

What You’ll Do

• Architect the front‑end platform: define patterns, conventions, and tooling that keep our React + TypeScript codebase fast, modular, and a joy to work in.
• Own the design‑system & component library: evolve our design tokens, accessibility standards, and Storybook workflow to enable rapid, consistent product development.
• Scale data‑driven interfaces: design frameworks for rendering billions of rows, live‑updating charts, and AI‑assisted insights without breaking Core Web Vitals.
• : champion CI/CD pipelines, testing strategy, and local‑dev ergonomics so every engineer can ship confidently in minutes, not days.
• Mentor & multiply: coach senior engineers, review critical PRs, and host architecture workshops that raise the bar for code quality and craftsmanship.
• Collaborate deeply: partner with product, design, and backend/platform teams to translate fuzzy problems into elegant, scalable solutions.

Tech Ecosystem You’ll Shape

React · TypeScript · Vite · NextJS · WebAssembly (DuckDB, WebGPU) · D3/visx · Storybook · Tailwind CSS · Jest · Cypress · Playwright ·

What You Bring

• 8+ years building and evolving large‑scale web applications.
• Proven expertise in front‑end architecture: modular codebases, micro‑frontends, design‑systems, performance‑budgeting, and scalability.
• A portfolio of data‑heavy, real‑time UIs and reusable component libraries used by multiple teams or products.
• Mastery of TypeScript, modern CSS methodologies (Tailwind, CSS Modules, CSS‑in‑JS), and front‑end testing (Jest, Testing Library, Cypress/Playwright).
• Passion for developer experience: local‑dev speed, CI/CD, linting/tooling, DX documentation, and mentoring.
• Bachelor’s or Master’s in CS—or equivalent real‑world mastery.

Bonus Points

• OSS contributions to front‑end tooling, design‑systems, or data‑visualization libraries.
• Deep WebSockets expertise for real‑time collaboration.
• Experience building Progressive Web Apps with robust offline support.
• Familiarity with design‑token pipelines and themeable UI frameworks.

How We Work

• Speed with craftsmanship: short feedback loops, continuous delivery, rigorous peer reviews.
• Performance first: Time‑to‑Interactive, bundle size, and UX motion are first‑class product metrics.
• Inclusive, global team: collaborate with skilled, authentic engineers across the US, India, and Europe.
• Ownership culture: you architect, you guide, you measure, you iterate.

Ready to craft the front‑end platform that powers the future of product, support, and developer collaboration? Apply now or reach out directly—let’s talk architecture, data, and next‑level DX.
