Job Description: As a Staff Software Engineer on the Enterprise Software Engineering team, you will design and build the applications, services, and integrations that keep Shield AI's business running – connecting the systems our engineering, manufacturing, supply chain, and finance teams depend on every day. You will work primarily in C#/. NET with React on the frontend, building distributed, message-driven systems in the cloud and bringing AI capabilities into the tools our people use. This is a hands-on, senior engineering role, where you will drive solutions from requirements, system design through deployment and support – sometimes leading a project, and at other times working closely with your teammates on a shared codebase. We move fast, so we are looking for someone who learns quickly, hits the ground running, and is comfortable making sound decisions with incomplete information. What you'll do: - Design, build, and maintain enterprise applications, APIs, and services using C#/. NET and React, with Python where it is the right tool for the job. - Architect and implement distributed, event-driven systems using message brokers (e. g. , RabbitMQ, Kafka, Azure Service Bus, MQTT) and service frameworks such as NServiceBus or MassTransit.

- Build reliable integrations between enterprise systems (e. g. , PLM, ERP, identity, and engineering platforms), handling long-running workflows, retries, and failure recovery. - Apply proven system design patterns – such as Saga/process managers, outbox, CQRS, and idempotent consumers – to deliver scalable, resilient, maintainable solutions. - Design and integrate AI capabilities into applications, such as LLM-powered features, agents, and intelligent automation. - Use AI-assisted development tools to accelerate delivery while maintaining high standards for code quality, security, and review. - Deploy and operate services in Azure and/or AWS for our team and other teams across the business, applying sound practices for security, networking, identity, reliability, and cost. - Use existing CI/CD and developer platforms (GitLab, Azure DevOps, GitHub, Artifactory, SonarQube) to build, test, and ship software; contribute pipeline changes as your projects require. - Instrument services for observability and troubleshoot asynchronous and distributed processes in production. - Collaborate closely with fellow Staff engineers – contributing to design reviews, code reviews, and the team's engineering standards – and lead projects when the work calls for it. - Partner with stakeholders across the business to understand problems, shape requirements, and deliver solutions with measurable impact. Required qualifications: - Typically requires a minimum of 7+ years of professional software engineering experience, with a bachelor's degree in Computer Science or a related field; or equivalent practical experience. - Deep expertise in C# and . NET (. NET 6+ / ASP. NET Core, an open-source web development framework | . NET Core), including building RESTful APIs, background services, and Entity Framework or similar data access. - Professional experience building frontends with React (TypeScript preferred). - Hands-on experience with messaging and event-driven architecture using RabbitMQ, Kafka, MQTT, Azure Service Bus, or similar technologies, including an understanding of delivery guarantees, ordering, retries, and dead-letter handling.
