If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.

We are building, iterating, and getting to space-fast. Our team thrives on action. We leverage deep experience in the space industry with engineering reimagined for speed and agility. We design, test, and deploy real systems that fly. If you want to own critical communications for a satellite mission, keep reading.

We're looking for builders, problem-solvers, and system thinkers. We are seeking a Senior Communication Engineer II to lead the end-to-end integration and verification of communication functions for our communication payload products. This highly technical role combines deep domain expertise in communication systems with hands-on integration and test execution and technical leadership responsibilities.

You will play a critical role in the architecture definition, execution, and delivery of our communication payload products leading requirement definitions, contributing to algorithm development, driving Special Test Equipment (STE) design, and owning verification and final sell-off. You will operate with a high degree of autonomy and provide technical leadership across integration and verification activities.

JOB DUTIES AND RESPONSIBILITIES
  • Lead the development of Cesium Astro's Communication System and Subsystems Integration and Tests and validate space systems requirements and interfaces.
  • Collaborate with System Engineering processes for requirements management, flow down, and traceability.

  • Lead selection and definition of data layer configuration
  • Own lab and equipment strategy, including management and optimization, and guiding key equipment purchase decisions.  
  • Architect and Develop Communication test systems and collaborate with System Engineering developing test plans, and implementation of test plans and procedures.
  • Lead execution of verification/validation tests, ensuring completeness, quality, and traceability of results; present findings to key stakeholders.
  • Work closely with design teams to verify and evaluate system level performance.
  • Independently draw conclusions from test results, debug complex system-level issues, and provide actionable feedback to design and verification teams.
  • Adapt and optimize test plans based on evolving hardware/software capabilities and test infrastructure constraints.
  • Design and oversee time-synchronized test setups using signal generators and spectrum analyzers to validate timing budgets.
  • Thrive in a fast-paced startup environment and take ownership of critical test systems for leading-edge satellite communication systems.
  • Provide technical leadership and mentorship to junior engineers; establish best practices for integration and verification
  • Drive continuous improvement in test methodologies, automation, and lab infrastructure
