Job responsibilities

• Lead the design and implementation of full-stack applications across several programs, covering backend services, frontend applications, and database architecture
• Contribute to system architecture decisions, including modularization, service decomposition, integration patterns, and technology trade-offs
• Participate in the full SDLC: requirements analysis, solution design, implementation, peer reviews, testing, deployment, production support, and continuous improvement
• Implement and promote engineering best practices for testing, logging, documentation, code review, traceability, and maintainability
• Define and improve CI/CD pipelines, automated build/test/deploy workflows, release readiness, and deployment quality gates
• Build product-quality user interfaces for engineering workflows, including simulator-facing and command/telemetry-oriented interfaces where applicable
• Develop and evolve ground operations tools, supporting mission readiness, command preparation, telemetry monitoring, anomaly investigation, and operator workflows
• Work closely with spacecraft, payload, AIT, and ground segment stakeholders to translate operational concepts into reliable, maintainable, and traceable software capabilities
• Mentor other engineers through design reviews, code reviews, technical coaching, and collaborative problem solving
• Identify technical debt, propose pragmatic improvements, and help shape engineering standards for long-term sustainability
• Partner with infrastructure and DevOps teams to improve environments, deployment automation, observability, reliability, and operational support
• Ensure software is built with security by design, including authentication/authorization, secure secret handling, input validation, least privilege principles, and secure API practices
