Technical Skills * Hands-on experience architecting and integrating AI/LLM capabilities into production enterprise workflows. This means you have built it, for example: Designed and deployed LLM-based features or automations (RAG, agents, classification, extraction, etc.) Integrated models with enterprise systems via APIs, orchestration tools, or data pipelines Owned decisions on architecture, evaluation, security/governance, and cost or performance tradeoffs * Expertise in modern programming languages such as Node.js, TypeScript, Next.js, C#.NET, C/C++, Python. * Deep expertise with Azure or AWS, Docker, Git/GitHub/GitLab Pipelines, and Kubernetes. * Extensive experience with relational and NoSQL databases, including PostgreSQL, MS SQL Server, and MongoDB. * Extensive experience designing and developing microservices, Serverless Architecture, RESTful APIs, OOP/OOAD, Async Messaging (SNS/SQS/RabbitMQ), and Single Sign-On (SSO/IAM). Leadership & Methodologies * Proven ability to act as a high-leverage individual contributor and mentor. * Strong expertise in process improvement, branching/tagging strategies, build/release management, and developer ergonomics. * Strong communication and documentation skills with a demonstrated ability to translate complex architectural trade-offs to leadership and stakeholders. Preferred Qualifications * Bachelor's Degree in Computer Science or a related technical field. * Prior experience in SaaS platforms or real-time storage/telemetry systems. * Experience bridging real-time/test systems with enterprise software * Experience with real-time embedded systems * Experience with LabVIEW or other high-rate data acquisition systems Physical Requirements: Prolonged periods of sitting at a desk and working on a computer ## Description When a rocket engine ignites on the test stand, hundreds of thousands of sensor readings per second generate a massive torrent of mission-critical data. We are seeking a highly experienced, hands-on Staff Software Engineer/Architect to drive the vision, design, and execution of our scalable enterprise platforms that capture, stream, and analyze hot-fire test data in real time. In this mission-critical role, you will bridge the gap between low-level sensor streams and high-throughput cloud analytics. You will lead a cross-functional engineering team to transform raw combustion chamber pressures, cryogenic flow rates, and high-frequency vibration data into actionable propulsion insights - powering next-generation orbital flight systems. You will modernize legacy platforms into high throughput microservices/serverless architectures, manage cloud deployments, and interface directly with engineering leadership. Key Responsibilities System Architecture & Cloud Engineering * Architect, build, and optimize enterprise-grade services and high-throughput backend APIs to support advanced analysis of high-rate rocket engine telemetry data. * Design architectures that integrate enterprise/cloud platforms with real-time/embedded/telemetry data-acquisition systems while meeting strict compliance requirements. * Design systems that allow legacy and modern components to work together to improve operational efficiency for propulsion design, engine testing and manufacturing * Own end-to-end cloud infrastructure design using Azure and/or AWS. Drive Infrastructure as Code (IaC) and containerization strategies using Docker and Kubernetes. * Architect robust integration hubs and collaborate with specialized propulsion teams to integrate advanced technologies like predictive embeddings and natural language processing (NLP) into core workflows. DevOps & CI/CD Optimization * Build, repair, and optimize continuous integration and deployment pipelines to reduce deployment complexity and improve developer velocity. * Set up reproducible local development environments (e.g., docker-compose) and maintain high standards for system profiling, automated testing, and observability. Technical Leadership & Operations * Serve as the technical owner for core systems, balancing Dev and Ops responsibilities, incident response, and performance monitoring for both software systems and rocket engine hot fire testing. * Partner closely with test, manufacturing and propulsion engineers to design best-in-class operational systems for the design, test and manufacturing of rocket engines and related components. * Mentor senior and junior software engineers and provide guidance on technical skills to grow the team.
