## Job description

## Why Harvey

At Harvey, we’re transforming how legal and professional services operate. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come. This is a rare chance to help build a generational company at a true inflection point. We have strong product-market fit and world-class investor support. We’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched. Our team moves fast, takes ownership, and is deeply committed to the mission — operating with intensity, staying close to our customers, and pushing each other for excellence. We live by three values: Decisiveness, Simplicity, and Job's Not Finished. We act quickly on clear judgment over perfect information, we believe simplicity is what scales, and we're never satisfied with where we are. If you want to do the best work of your career alongside people who share that drive, we'd love to build with you. At Harvey, the future of professional services is being written today — and we’re just getting started.

## Role Overview

Legal professionals spend most of their day in Microsoft Word: drafting, reviewing, and refining complex documents that shape meaningful outcomes. Harvey in Word brings AI-powered capabilities directly into Word, enabling lawyers to draft faster, run playbook reviews, and perform agentic editing, all without leaving their workflow. It's one of our most strategic product lines and a key part of how we meet lawyers where they already work.

As a Staff Software Engineer on the Embedded Experiences team, you will own and lead the development of Harvey in Word, our Microsoft Office Add-in built on OfficeJS, alongside our other Microsoft Office integrations. You'll architect and ship features that integrate seamlessly with Word, handling the unique challenges of building performant, polished experiences within the Office Add-in environment.

We're looking for someone with deep expertise in OfficeJS and Office Add-in development, ideally from building a similar product at scale. You'll join a team of highly motivated, skilled engineers who hold everything they touch to the highest standards, from architecture to code to user experience. You may also contribute to our Outlook integration and help build the next generation of agentic AI interfaces across the Microsoft suite.

This role is based in New York, NY. We use a hybrid in-person work model and offer relocation assistance to new employees.

## What You'll Do

- Own and lead the technical direction of Harvey in Word, our flagship Office Add-in product, alongside our other Microsoft Office integrations.
- Build the AI-native editing experience: agentic document rewrites, real-time redlining, and playbook automation that transforms how lawyers work
- Design and build sophisticated integrations with Microsoft Word using the OfficeJS API, including document manipulation, playbook reviews, and AI-assisted drafting
- Architect scalable, maintainable solutions that handle the constraints and quirks of the Office Add-in environment across platforms (Windows, Mac, Web)
- Build polished, high-performance interfaces with crisp interactions and resilient error handling
- Collaborate with product, design, and backend teams to shape APIs and UX for AI-powered features like streaming results and tool-calling workflows
- Navigate Office Add-in requirement sets, versioning, and cross-platform compatibility to ensure broad, reliable support
- Contribute to Harvey in Outlook and shape the next generation of agentic AI interfaces across the Microsoft suite
- Mentor engineers, drive technical decisions, and raise the bar on quality and developer experience

## What You Have

- 10+ years of software engineering experience, with significant depth in Office Add-in development using OfficeJS
- Experience building and shipping a production Office Add-in product, ideally one used at enterprise scale
- Strong proficiency in JavaScript/TypeScript, HTML, and CSS
- Deep understanding of Office Add-in architecture, requirement sets, manifest configuration, and cross-platform considerations
- Experience with React or similar modern frontend frameworks
- Track record of shipping highly intuitive products with strong attention to detail
- Familiarity with Microsoft Office Add-in guidelines and AppSource submission process is a plus

## Nice to Have

- Experience with Outlook Add-ins or other Microsoft 365 integrations (SharePoint, Teams)
- Background in legal tech or enterprise SaaS
- Experience building products that integrate with AI/LLM capabilities

## Compensation Range

$231,000 - $340,000
