Senior .NET Engineer (Cloud & AI-enabled engineering)

Job Overview

As a Senior Software Engineer, your primary mission will be to design, write, test, deploy, and support our Relativity cloud (Azure) software products in .NET/C#. You will work in a scrum team collaborating with other members of the engineering team and business stakeholders to support the development of products, features and services that drive and evolve our RelativityOne platform. You will use your knowledge to mentor less senior team members and support your team’s tech lead in his duties.

Responsibilities

• Contribute to a Scrum team throughout all complex phases of a service lifecycle from conception through design, development, testing, deployment, and ultimately operation.
• Architect and design performant, scalable, and secure software to a high degree of quality – not simply focusing on meeting requirements.
• Apply OOA, OOD, and OOP principles and design patterns in C# and TypeScript / JavaScript, following SOLID principles.
• Provide technical guidance to the software development team to ship high‑quality, performant, secure software that operates on data at a massive scale.
• Participate in code reviews for projects written by your team.
• Conduct comprehensive unit and integration testing, perform static analysis, and develop a rigorous test strategy.
• Recommend and drive improvements to the software development processes.
• Identify, document, automate, and engineer processes for repetitive tasks.
• Contribute to and mature existing automated deployment/upgrade CI/CD workflows.
• Leverage monitoring and observability to proactively identify and fix problems.
• Improve software quality and completeness, and share design and implementation knowledge.
• Troubleshoot issues, fix defects and respond to client‑specific problems.
• Provide technical guidance to team members through education and coaching.
• Participate in regular on‑call technical support shifts as second‑line support when necessary.
• Embrace and contribute to a learning/growth culture and promote a healthy work environment.

Minimum Qualifications

• Bachelor’s in computer science, engineering, or a related technical degree, or equivalent work experience.
• 5+ years of experience in commercial‑grade software development using C#.
• Experience developing cloud‑scalable solutions using cloud native patterns (Azure preferred).
• Experience working with various scalable database systems.
• Proficient in building advanced cloud DevOps mindsets, including CI/CD processes and tools (e.g., GitHub Actions, Harness, LaunchDarkly) and mature observability.
• Ability to build mature deployment and release solutions.
• Following software engineering best practices: unit testing, code reviews, design documentation, debugging and troubleshooting skills.
• Experience in an agile software team, including mentoring, feature leadership, and cross‑group collaboration.
• Fluency in English.
• Hands‑on experience using AI tools as part of everyday engineering workflow (AI‑assisted code generation, refactoring, review, technical design, solution exploration, documentation, planning and structuring development and release activities), and ability to critically evaluate AI output and take ownership of final technical decisions.

Preferred Qualifications

• Experience with container orchestration platforms such as Kubernetes.
• Experience with configuration management and IaaS (e.g., Pulumi).
• Experience with observability frameworks and solutions (e.g., New Relic, Grafana).
• Experience with web development using JavaScript/TypeScript and modern web frameworks (e.g., Angular, React, Vue).
• Experience with .NET Core development.

Benefits

• Comprehensive health, dental, and vision plans.
• Parental leave for primary and secondary caregivers.
• Flexible work arrangements.
• Two week‑long company breaks per year.
• Additional paid time off.
• Long‑term incentive program.
