About The Position

At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. 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 seeking a highly skilled Principal Electrical Engineer I to lead the design, development, integration, test, and flight qualification of advanced spaceborne payloads.
This post focuses on the role of Unit Lead (Responsible Engineer) in our Reconfigurable Processing Unit (RPU) product line. CesiumAstro RPUs are complex, VPX-based electronics boxes consisting of our software-defined radios, single-board computers, power supply modules, and RF front ends, driven by CesiumAstro modems and software.
The Unit Lead is responsible for both technical definition and execution of a new RPU product. This combines deep, multi-disciplinary technical accountability with responsibility for on-time schedule execution. The project may include the development of new VPX module products, new backplanes and interface options, and/or new software features, coming together into a qualified, customer-ready product.
The Unit Lead is the leader of the multidisciplinary technical team, the primary point of contact for the program manager, and often a key interface point for our customers. Success in this role requires strength in technical topics as well as project management, leadership, and communication in a fast-paced startup environment.

Requirements

• Bachelor’s degree or higher in Electrical Engineering or a related field.
• 9+ years of engineering experience in electronics hardware development.
• Hands-on experience with related technologies such as software-defined radios.
• Leadership experience, including mentoring or leading multidisciplinary engineering teams.
• Strong knowledge of systems engineering practices, requirements flowdown, verification/validation, and configuration management.
• Excellent communication skills with ability to present complex technical information to diverse audiences.

Nice To Haves

• Demonstrated understanding of payload control systems, digital interfaces, command & data handling, and embedded hardware/software interactions.
• Proven experience executing or overseeing flight qualification and environmental test campaigns (TVAC, vib/shock, EMC, radiation considerations).
• Experience managing hardware/software product development projects.
• Experience with radiation-tolerant design.
• Experience with high-rate manufacturing, rapid development cycles, and/or NewSpace ecosystems.
• Prior role as a Responsible Engineer, Technical Lead, IPT Lead, or Chief Engineer on flight hardware.
• Background in digital signal processing, beamforming algorithms, or embedded firmware for payload control.
• Experience mentoring less-experienced project engineers and design engineers in associated discipline.
• High energy and a “get it done” attitude.

Responsibilities

• Serve as the RPU Unit Lead and primary technical point of contact for the box throughout the product development lifecycle.
• Lead the end-to-end engineering effort for the box, including architecture, design, prototyping, integration, test, environmental qualification, and flight readiness.
• Coordinate and direct a team of RF, digital, power, mechanical, thermal, software, and systems engineers to ensure consistent and timely technical execution.
• Hold schedule accountability for the box development.
• Develop and review payload control schemes, internal data interfaces, command & telemetry architecture, and firmware/software integration as needed.
• Manage all flight qualification activities, including environmental test planning (thermal vacuum, vibration, shock, EMC), margin assessment, and final acceptance testing.
• Own the transition to volume production, including manufacturability, testability, and customer-facing documentation.
• Generate and maintain box-level documentation: requirements, ICDs, block diagrams, test plans, verification matrices, risk registers, and design reviews.
• Interface with spacecraft systems engineering, mission assurance, manufacturing, vendors, and test facilities.
• Drive root cause analysis, anomaly resolution, and technical risk mitigation throughout development and test campaigns.
• Communicate status, technical trades, risks, and design decisions to internal leadership and external customers.

Benefits

• Full-time employment offers include company stock options and a generous benefits package including health, dental, vision, HSA, FSA, life, disability and retirement plans.
