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.

- Scale document ingestion and processing that is growing at 10x every 6 months
- Design massive data collection from over 50+ legal jurisdictions
- Build government-level security for top governments and firms
- Lead projects that delight customers in bringing AI to web, desktop, mobile, Google Docs, MS Word, and API experiences.
- Build AI-platform and AI-native features like agentic orchestration layers, tool calls, and retrieval systems.
- Ship across the full stack—leveraging React and TypeScript on the frontend alongside Python and Postgres on the backend—to architect intuitive UX and robust APIs for streaming results, long-running processes, and complex tool-calling workflows.
What You Have
- 10+ YoE (post-BS/MS) in a product focused full-stack software engineering role.
- Experience with React, Typescript, CSS (we use TailwindCSS), Python, or related.
- Track record of building fast-growing SaaS products.
- Track record of shipping highly intuitive products, strong attention to detail.

Senior Level Full-stack Software Engineer Jobs: Frequently Asked Questions
How do I get a senior level full-stack software engineer job?
Employers at this level look for engineers who can own systems end to end, not just contribute to them. Demonstrating that you have driven architectural decisions, mentored junior engineers, and shipped features that moved business metrics will set you apart. A portfolio of complex, production-grade work and the ability to discuss trade-offs clearly in interviews carries more weight than breadth of technologies alone.
Which companies hire senior level full-stack software engineers?
Companies hiring senior level full-stack software engineers right now include Capital One, Northrop Grumman, and BNY, based on current listings on Migrate Mate as of November 2026. Hiring at this level comes from a broad range of employers, including high-growth startups looking for technical leads, established technology companies scaling existing platforms, and enterprises modernizing legacy systems.
Are there remote senior level full-stack software engineer jobs?
Yes, remote and hybrid options are widely available at the senior level. About 40% of senior level full-stack software engineer openings are remote or hybrid as of November 2026, reflecting how broadly distributed engineering teams have become. Senior engineers are generally trusted to work independently, which makes remote arrangements more common at this stage than at earlier career levels.
What makes a full-stack software engineer role senior level?
Senior level roles are defined by ownership and scope rather than task execution. At this stage, engineers are expected to design systems rather than implement specs, identify problems before they are assigned, and guide the technical growth of others on the team. The distinction from mid-level is less about the technologies used and more about who sets direction, resolves ambiguity, and is accountable for outcomes.
Which industries hire the most senior level full-stack software engineers?
Senior level full-stack software engineer roles concentrate in Technology & Software, Consulting & Professional Services, and Insurance, based on current listings on Migrate Mate as of November 2026. These sectors drive demand because they rely on complex, continuously evolving digital products where experienced engineers capable of leading architecture and delivery decisions are critical to sustained growth.
