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 are committed to expanding access to technology and supporting pro bono legal work.

What We Do
At Relativity, engineers do more than write code - they build systems that enable users to uncover insights from complex data at scale using cloud-native architecture, AI, and modern tools.

Join the Data Transfer group within our Ingestion Department, a high-impact engineering team responsible for building and scaling the infrastructure that powers secure, reliable, and high-throughput data movement across our SaaS platform.

About The Role
We are seeking an experienced Lead Software Engineer to develop software and guide a team in applying engineering best practices to deliver high-quality, maintainable, and scalable systems.

This role serves as a technical liaison across teams, helping resolve dependencies, improve engineering processes, and proactively identify and mitigate risks to software delivery.

Job Description And Requirements
WHAT YOU’LL DO

• Define architecture strategy and non-functional design to meet SLO/SLA and cost goals, ensuring security-by-default and regulatory alignment
• Lead multi-team Azure delivery and enable safe deployments across services such as AKS, Event Hubs/Service Bus, and Cosmos DB or SQL
• Implement practices such as policy-as-code, canary and blue-green deployments, environment parity, and automatic rollback
• Own reliability and observability through standardized tracing, metrics, and logging, as well as SLOs, error budgets, and actionable alerting
• Drive post-incident improvements by leading root cause analysis and implementing fixes that prevent recurrence
• Champion Infrastructure as Code and platform “paved roads” to improve consistency and developer experience
• Guide engineers through design reviews and establish clear quality standards while unblocking cross-team dependencies
• Collaborate with Product to make data-informed trade-offs across reliability, cost, and delivery speed
• Influence stakeholders across teams by negotiating priorities, mediating conflicts, and managing expectations
• Support team growth by contributing to development plans, delivering actionable feedback, and raising the hiring bar
• Communicate effectively through architectural decision records (ADRs) and narratives that connect technical trade-offs to customer and business outcomes

Required
WHAT WE’RE LOOKING FOR

• 7+ years of experience building distributed SaaS systems using .NET/C# or similar technologies, including 3+ years leading initiatives or teams
• Deep expertise in Azure, including AKS, Service Bus/Event Hubs, and Cosmos DB or SQL, as well as multi-region patterns
• Proven ownership of SLO/SLA outcomes, including on-call leadership and driving root cause analyses that eliminate repeat incidents
• Strong experience with observability at scale, including OpenTelemetry tracing, metrics, logging, dashboards, and alert design
• Experience with CI/CD practices, including GitHub Actions or similar tools, canary/blue-green deployments, feature flags, and automated rollback
• Strong stakeholder communication skills with the ability to influence across teams and communicate clearly in English
• Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience

Preferred

• Experience with FinOps practices including cost modeling, right-sizing, autoscaling strategies, and capacity planning
• Strong background in Infrastructure as Code (e.g., Pulumi), Kubernetes operations, and container security practices
• Experience in platform enablement, including internal SDKs, templates, and “golden paths”
• Familiarity with service mesh technologies
• Experience with data streaming systems such as Kafka or Azure Event Hubs, and large-scale ingestion/ETL pipelines
• Knowledge of multi-tenant scaling techniques, including throttling and backpressure strategies
