Lead Software Engineer (with .NET)

Job Overview

We are seeking an experienced Lead Software Engineer who will join Relativity’s Data Transfer group, a high-impact engineering team at the heart of our Ingestion Department. We build and scale the infrastructure that powers secure, reliable, and high-throughput data movement across our SaaS platform. The Lead Software Engineer develops software and guides a team to apply software engineering best practices to provide high-quality, maintainable, reusable, performance, and scalable software. You will be a technical liaison between your team and other development teams to resolve dependencies, improve and apply software engineering best practices and processes, and find and address risks to the delivery of software.

Job Description and Requirements

Your Role in Action: 

• Define architecture strategy and non-functional design to meet SLO/SLA and cost goals, with security-by-default and regulatory alignment   

• Lead multi-team Azure delivery and safe deployments (AKS, Event Hubs/Service Bus, Cosmos/SQL) with policy-as-code, canary/blue-green, environment parity, and automatic rollback   

• Own reliability and observability: standardized tracing/metrics/logging, SLOs and error budgets, actionable alerts, and post-incident fixes that prevent recurrence   

• Champion Infrastructure as Code and platform "paved roads" that raise consistency and developer experience   

• Coach and elevate engineers via design reviews and clear quality bars; unblock cross-team dependencies   

• Collaborate with Product on data-backed trade-offs across reliability, cost, and delivery speed   

• Influence without authority: negotiate priorities, mediate conflicts, and manage expectations with Product and executives across teams   

• Grow people: help build growth and coaching plans, deliver actionable feedback, and raise the hiring bar 

• Communicate for impact: write high-signal decision records (ADRs) and craft narratives for non-technical leaders that tie technical trade-offs to customer outcomes and cost   

Required Skills

• 7+ years building distributed SaaS in .NET/C# or similar; 3+ years leading initiatives or teams 

• Deep Azure expertise: AKS, Service Bus/Event Hubs, Cosmos DB or SQL, multi-region patterns 

• Proven ownership of SLO/SLA outcomes, on-call leadership, and RCAs that eliminated repeat incidents 

• Observability at scale: OpenTelemetry tracing, metrics, logging; dashboards and alerts that drive action 

• CI/CD excellence: GitHub Actions or similar; canary/blue-green deployments; feature flags; automated rollback and policy gating 

• Strong stakeholder communication and influence; clear written and verbal English 

• Bachelor’s degree in Computer Science, Engineering, or equivalent experience 

Nice to Have

• FinOps: cost modeling, right-sizing, autoscaling, and capacity planning for high-throughput systems 

• Infrastructure as Code (Pulumi); Kubernetes operations; container security and supply chain hygiene 

• Platform enablement: internal SDKs/templates, golden paths; service mesh experience 

• Data and streaming: Kafka or Azure Event Hubs; large-scale ingestion/ETL; multi-tenant throttling and backpressure techniques
