Epsilon3 • Los Angeles, CA

2d • $130,000 - $190,000 • Remote

About The Position

Epsilon3 is a multi-product operations management platform revolutionizing the way teams build, launch, and operate spacecraft and other advanced hardware systems. Launched in 2021, our company is led by engineers from SpaceX, Google, and NASA, who have experience supporting over 100 space missions. Innovative teams at Blue Origin, Rocket Lab, Axiom Space, Firefly Aerospace, and many others depend on our web-based (SaaS) solutions to plan and track high-stakes procedures. We raised a $15M Series A funding round led by Lux Capital, Y Combinator (YC S21), and other world-class investors. 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. Technical Challenges 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.

Requirements

• 6+ years of experience in Product Design, UI/UX, or Interaction Design, preferably within complex enterprise SaaS, industrial software, or aerospace.
• Masters or Bachelor’s Degree in HCI, Design, Computer Science, or a related technical field.
• Expert Prototyper: Proven ability to move from abstract service blueprints to high-fidelity, testable prototypes that simulate real-world data and logic.
• Systems Thinker: Deep experience in Information Architecture and a track record of simplifying high-density data for professional users.
• Technical Literacy: Strong understanding of modern web technologies (React, Node.js) and the ability to design for the constraints of real-time, high-security cloud/on-prem environments.
• Startup Mentality: Comfortable navigating ambiguity, managing multiple concurring projects, and iterating rapidly in a Lean/Agile environment.
• US Citizenship (future security clearance may be required)
• Must be located in the US

Responsibilities

• 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.
