Advanced Software Engineer

Posting Type Hybrid/Remote Job Overview Who We Are Relativity is a leading legal data intelligence company building technology that helps users organize data, discover the truth, and act on it with confidence. Our AI‑powered, cloud platform, RelativityOne, transforms massive volumes of complex information into actionable insights for litigation, investigations, regulatory inquiries, data breach responses, and other high‑stakes legal work where accuracy and trust are crucial.

The world’s largest law firms, corporations and government agencies rely on Relativity’s legal AI software to securely surface and manage the most relevant and impactful information in their matters. Beyond our commercial impact, we’re deeply committed to expanding access to technology for academic institutions through Relativity Academic and supporting pro bono legal work through Justice for Change. What We Do At Relativity, engineers don’t just write code— they harness AI tools to architect, optimize, and deliver scalable software faster and shape the future of legal technology.

They shape how industries uncover critical insights, ensure compliance, advance access to justice and continuously evolve our platform using the latest technologies, including cloud-native architectures, AI capabilities, and modern developer tooling. Our AI powers privacy programs, identifies confidential information, and detects language indicating misconduct. We’re reimagining how legal professionals uncover truth at scale, and engineering is at the heart of that transformation. Our team builds the AI platform that Relativity's aiR products run on.

We own the systems that orchestrate large-scale document review by LLM — durable workflows that carry a job through millions of documents — and the gateway that routes every model request across cloud regions and sovereign environments while managing capacity, throughput, and cost. Every AI feature our customers touch runs through our stack, and the work is equal parts distributed systems, LLM infrastructure, and reliability engineering.

If you’re passionate about solving hard problems, designing for scale, and building tools that matter—while working in a culture that values transparency, innovation, and shared success— Relativity offers the opportunity to make a measurable difference in the marketplace.

Proficiency in Python and/or C#/.NET, with production experience running services on Kubernetes in a major cloud. A track record of debugging and improving systems in production: distributed tracing, metrics, and comfort owning a service others depend on, on-call included. Preferred Experience with full-stack development and modern UI frameworks.

Familiarity with performance or cost optimization. Familiarity with AI-development tools like GitHub Copilot, Cursor or Claude Code. Experience building on LLM APIs (Azure OpenAI, OpenAI, Anthropic): prompt and model versioning, evaluation, streaming, token accounting, or working within rate limits and provisioned throughput. Experience with durable workflow engines (Temporal, Airflow, Step Functions) or high-volume batch and streaming data pipelines. Interest in agentic systems — MCP, tool calling, and the infrastructure that makes them safe to run in a regulated environment.
