What the job involves

• We are looking for a Senior Product Designer to lead the end-to-end design of mission‑critical interfaces. You will work at the intersection of human‑computer interaction and aerospace engineering, solving complex problems related to real‑time telemetry, AI‑assisted decision making, and high‑stakes procedure management
• As a senior member of the team, you will be helping map the entire service ecosystem— translating research and feedback to service blueprints and into high‑fidelity, testable prototypes
• Human‑AI Interaction: Designing intuitive patterns for AI/ML features that boost team efficiency and enable fast, data‑driven decisions without sacrificing human agency
• Complex Service Blueprints: Mapping multi‑user, multi‑environment workflows where real‑time synchronization and traceability is mission‑critical
• Data Visualization: Architecting visualizations for high‑bandwidth data streams and telemetry that remain legible under high‑stress operational conditions
• Design for Reliability: Ensuring mission‑critical security and reliability within a modern, delightful web and app based (SaaS) environment
• Service Design & Information Architecture: Lead the creation of service blueprints and complex user flows that map out the entire lifecycle of a mission
• End-to-End Execution: Own the full design cycle: from deep‑dive user research and discovery calls to ideation, high‑fidelity prototyping, and developer handoff
• Prototyping & Testing: Build advanced, data‑driven prototypes (using Figma, Framer, or code) to validate complex workflows with users before they hit production
• AI Tooling Integration: Research and implement AI‑assisted design workflows and advocate for UX patterns that make AI features within the platform transparent and actionable
• Design Systems: Contribute to and evolve our specialized design system, ensuring consistency across operational dashboards, procedure tools, and mobile solutions
• Collaborative Leadership: Work closely with engineering to ensure technical feasibility and participate in customer discovery to translate raw requirements into elegant solutions
