Backend Software Engineer (.NET)

Job Overview As an Advanced Software Engineer (.NET) on the Unstructured Storage Services team, you’ll design and build cloud-native storage capabilities that power RelativityOne. You’ll ship backend API first services that are scalable, resilient, secure, and cost-aware—using Azure storage primitives (Blob Storage, ADLS) and proven patterns for multi-tenancy, lifecycle management, compression, and performance at scale. You’ll join Cloud Infrastructure division, a group responsible for core platform capabilities (compute, networking, and storage). Our team provides self-serve, reliable unstructured storage services for product engineering and external customers — so feature teams can move faster without reinventing storage, reliability, and operational tooling. You’ll partner closely with product engineers, SRE/operations, and security to validate designs, improve developer experience, and reduce operational burden. Job Description and Requirements Job Responsibilities • Design, build, and operate backend services for unstructured storage in RelativityOne (C#/.NET), with strong focus on reliability, scalability, security, and performance.  • Implement and evolve Azure-based storage solutions (Blob Storage, ADLS) including lifecycle policies, multi-tenant isolation, encryption, access controls, and cost optimization.  • Lead and participate in technical design reviews; document decisions and promote cloud-native storage patterns across engineering.  • Troubleshoot and resolve production issues; identify bottlenecks and reliability risks, and drive improvements through instrumentation, automation, and better operational playbooks.  • Contribute to the storage platform roadmap by evaluating new technologies and proposing incremental improvements that align with business needs and long-term system evolution.  • Collaborate with partner teams (product engineering, SRE, security) to deliver solutions end-to-end and improve developer experience.  • Participate in on-call rotation and incident response to support customers and maintain service health.    Minimum Qualifications • 3+ years of software engineering experience (backend services, distributed systems, or data/platform engineering).  • Strong C#/.NET (Core) development skills.  • Hands-on experience designing and implementing cloud-native storage solutions in Azure, AWS, or GCP (Azure preferred).  • Understanding of distributed storage fundamentals: partitioning, consistency models, data access patterns, and performance optimization.  • Experience with CI/CD (e.g., GitHub Actions) and shipping production services.  • Fluent English and strong written/verbal communication.  • Experience working with Agile methodologies (Scrum, Kanban).  Preferred Qualifications • Deep experience with at least one large-scale object storage system (Azure Blob Storage, ADLS, AWS S3, or equivalent).  • Infrastructure as Code experience (Terraform, Pulumi) and comfort working with cloud resource provisioning.  • Kubernetes and/or serverless architecture experience.  • Experience building platform services and improving internal developer experience (DX).  • Experience in regulated or data-sensitive environments (legal tech, healthcare, financial services).  • Python and/or PowerShell scripting.  • Bachelor’s degree in Computer Science or a related field (or equivalent practical experience).  Relativity is a diverse workplace with different skills and life experiences—and we love and celebrate those differences. We believe that employees are happiest when they're empowered to be their full, authentic selves, regardless how you identify.
