Senior Software Engineer, Core Infrastructure

Why Harvey

At Harvey, we're transforming how legal and professional services operate — not incrementally, but end-to-end. 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. With 1000+ customers in 60+ countries, 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 is sharp, motivated, and deeply committed to the mission. We move fast, operate with intensity, and take real ownership of the problems we tackle — from early thinking to long-term outcomes. We stay close to our customers — from leadership to engineers — and work together to solve real problems with urgency and care. If you thrive in ambiguity, push for excellence, and want to help shape the future of work alongside others who raise the bar, we invite you to build with us.

Role Overview

As a Software Engineer on the Core Infrastructure team at Harvey, you'll play a critical role in designing and building new infrastructure systems while equally scaling and strengthening our existing infrastructure. Our infrastructure is the foundation that powers every user interaction with Harvey — processing billions of prompt tokens and millions of daily requests across our global legal AI platform.

You'll work in an environment balanced between innovation — building new systems — and operational excellence, ensuring that Harvey remains resilient and efficient as it scales products, regions, customers, and usage. Your contributions will directly impact the reliability, scalability, and security of our platform as we serve the world's leading law firms and professional service providers.

What You'll Do

• Design and build scalable, fault-tolerant infrastructure systems that power Harvey's AI platform across multiple cloud regions
• Own and evolve our multi-cloud infrastructure (Azure, GCP), including Kubernetes orchestration, networking, and container management
• Lead technical initiatives around observability, incident response, and operational excellence — building systems that enable rapid detection and resolution of issues
• Architect and optimize our distributed systems for reliability, including load balancing, quota management, and failover mechanisms
• Partner with Product Engineering and Security teams to ensure our infrastructure is an accelerant, not a constraint
• Drive infrastructure-as-code practices, automation, and deployment pipelines to enable rapid, safe scaling
• Mentor junior engineers and contribute to a culture of technical excellence and continuous improvement

About You

You bring strong experience designing and operating large-scale distributed systems in production environments. You have deep expertise in cloud infrastructure (Azure, GCP, or AWS), containerization, and Kubernetes. You're comfortable working across the full stack — from networking and storage to application-level concerns — and you understand how to balance innovation with reliability.

You thrive in fast-moving environments, take ownership of problems from conception to resolution, and communicate clearly with both technical and non-technical stakeholders. You're passionate about building systems that scale elegantly and stay ahead of growth. Experience with legal tech, AI platforms, or mission-critical infrastructure is a plus.
