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 an Engineering Manager, Digital & Mixed-Signal Hardware to lead and coordinate our high-speed digital electronics teams across multiple sites and product lines. This leadership role is critical to ensuring architectural consistency and high-quality execution across a diverse portfolio of software-defined radios, space computing platforms, and phased array control systems. 
This position is a highly technical leadership role responsible for delivering well-engineered digital and mixed-signal hardware—on schedule—across all product lines. The role provides technical ownership for board- and system-level high-speed digital designs while leading team execution, staffing, and engineering process maturity in a fast-growing aerospace and defense startup environment. 
In addition to people and process leadership, this role contributes hands-on technical expertise to critical designs, architecture reviews, and complex debug activities, ensuring products are scalable, manufacturable, testable, and robust at production volumes. 

JOB DUTIES AND RESPONSIBILITIES

• Maintain technical integrity and engineering excellence for high-speed digital and mixed-signal electronics development across the company. 
• Establish, mature, scale, and enforce engineer-friendly digital hardware development processes, including high-speed interface design guidelines, signal integrity simulation workflows, and schematic and layout standards for dense, high-layer-count PCBs 
• Lead and participate in rigorous architecture and design reviews, ensuring appropriate subject matter expert (SME) engagement across digital, RF, power, firmware, and mechanical disciplines. 
• Provide system-level technical leadership for software-defined radio and computing units and phased array control architectures. 
• Apply strong working knowledge of adjacent disciplines—RF electronics, power electronics, thermal/mechanical engineering, firmware/software—to ensure board- and system-level success. 
• Contribute directly to board-level digital and mixed-signal designs as needed, particularly in high-risk or schedule-critical programs. 
• Lead or support complex debug efforts involving high-speed interfaces, large FPGA and processor implementations, and related technical topics.  
• Ensure digital hardware designs are buildable and testable at scale using DFM and DFT best practices. 
• Drive disciplined handoff from engineering to manufacturing through close collaboration with manufacturing engineering, supply chain, and production test engineering. 
• Ensure designs meet quality, reliability, and scalability requirements for aerospace and defense production environments. 
• Lead digital architecture decisions aligned with product performance and long-term technology roadmaps. 
• Partner with Supply Chain to ensure component availability, lifecycle risk mitigation, and cost awareness. 
• Drive design reuse, modular architectures, and platform commonality across products to accelerate execution and reduce risk. 

TEAM LEADERSHIP, STAFFING & PERFORMANCE RESPONSIBILITIES

• Build, scale, and lead a high-performing digital and mixed-signal hardware engineering team. 
• Advocate for realistic schedules while holding the team accountable to delivery commitments. 
• Lead hiring activities, including writing job descriptions, conducting interviews, and making hire/no-hire decisions. 
• Establish clear development paths and growth opportunities for high-performing engineers. 
• Address performance issues promptly and constructively. 
• Actively close skill gaps through hands-on contribution, training initiatives, or targeted hiring. 
• Provide one-on-one coaching, mentoring, and deep technical guidance. 
• Serve as a key contributor to early-stage engineering execution planning, in
