Job description

At DevRev, we’re building the future of work with Computer – your AI teammate.

Computer is not just another tool. It’s built on the belief that the future of work should be about genuine human connection and collaboration – not piling on more apps. Computer is the best kind of teammate: it amplifies your strengths, takes repetition and frustration out of your day, and gives you more time and energy to do your best work.

How?

Complete data unification

Most AI products focus on either structured data (like CRM records and support tickets), or unstructured data (like documents and emails). Computer AirSync connects everything, unifying all your data sources (like Google Workspace, Jira, Notion) into one AI‑ready source of truth: Computer Memory.

Powerful search, reasoning, and action

Once connected to all your tools and apps, Computer is embedded in your full business context. It can find and summarize, sure. Even more impressive: it offers employees insights, strategic and proactive suggestions, plus powerful agentic actions.

Extensions for your teams and customers

Computer doesn’t make you choose between new software and old. Its AI‑native platform lets you extend existing tools with sophisticated apps and agents. So your teams – and your customers – can take action, seamlessly. These agents work alongside you: updating workflows, coordinating across teams, and syncing back to your systems.

Computer brings people back together, breaking down silos and ushering in the future of teamwork, through human‑AI collaboration. Stop managing software. Stop wasting time. Start solving bigger problems, building better products, and making your customers happier.

We call this Team Intelligence. It’s why DevRev exists.

Trusted by global companies across multiple industries, DevRev is backed by Khosla Ventures and Mayfield, with $150M+ raised. We are 650+ people, across eight global offices.

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:

• 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.
• Elevate developer experience: 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

What You Bring

• 8+ years building and evolving large‑scale web applications.
• 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, CSSModules, 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.

The foundation of DevRev is its culture – our commitment to those who are hungry, humble, honest, and who act with heart. Our vision is to help build the earth’s most customer‑centric companies. Our mission is to leverage design, data engineering, and machine intelligence to empower engineers to embrace their customers.
