This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide. This role is part of the Emerging Systems business unit, which is focused on developing cutting-edge space technologies including TeraWave, Blue Origin's revolutionary space-based networking system. TeraWave is designed to deliver symmetrical data speeds of up to 6 Tbps, providing connectivity to locations unreachable by traditional methods and adding a space-based layer to existing network infrastructure. As a Principal Engineer for RF and Optical System Integration & Verification, you will own the end-to-end integration, bring-up, and verification strategy for TeraWave's RF and optical communications payloads, user/gateway terminals, and ground segment. You will be the technical authority who proves that the constellation's links work — from first light in an anechoic chamber and Compact Antenna Test Range (CATR), through hardware-in-the-loop (HITL) emulation of orbital dynamics, to on-orbit commissioning and steady-state flight operations. This is a Principal-level individual contributor and technical leadership role. You will oversee systems and projects across a broad domain, directing system owners across multiple teams on the design, delivery, and planning of integration and verification capability with no day-to-day oversight. You will set the technical direction for how Blue Origin verifies space-based RF and optical links, drive operational excellence across organizational boundaries, and serve as an advisor to leadership and customers on advanced technical studies. Success in this role means not only closing verification against complex requirements, but proactively identifying problems no one has yet identified and proposing novel, cutting-edge solutions where the path forward is not clear. Special Mentions This role will be onsite in one of these locations – Greater Seattle Area, WA, Cupertino CA. It is approved for temporary remote work exception while our local site is developed Relocation assistance available Travel may be required up to 25% of the time (test ranges, ground station sites, vendor facilities, mission operations centers, and standards bodies). Responsibilities include but are not limited to: Technical Ownership & Architecture Own the integration and verification (I&V) architecture and test automation framework for the TeraWave RF and optical system areas (payload, terminals, ground stations, links). Conduct trade studies, build prototypes, and provide early feasibility analysis to identify I&V architectural options across low-, medium-, and high-performance/high-cost test approaches, and propose the best path forward. Define and own the verification strategy and requirements traceability from ConOps and link budgets through subsystem test, system-level HITL emulation, environmental/chamber campaigns, and on-orbit validation. Develop, apply, and teach advanced technical principles across the full development cycle — requirements, design, analysis, build, verification, and test. Develop and deploy Agentic-AI systems for on-ground automated system validation, data acquisition, analysis, troubleshooting, identifying optimizations and executing test campaigns. Integration, Bring-Up & Test Execution Lead cross-functional integration campaigns with hardware, silicon, RF/antenna, optical, modem/DSP, flight software, SDN, networking, and systems engineering teams to bring up system features, troubleshoot problems, and deliver solutions. Direct lab- and site-level satellite and terminal bring-up, including RF line-up, optical bench alignment, clock/timing distribution, power, thermal, and networking test infrastructure, and rooftop/ground antenna integration. Own RF payload line-up and link budget verification: EVM, ACLR, PAPR, Tx power and spectral flatness, Rx sensitivity, adjacent channel selectivity, linearity/compression, phased-array beam formation, sidelobes, and pointing accuracy. Own optical link verification: coherent optical transceiver (ACO/DCO) characterization, pre-/post-FEC BER, OSNR and power budget margin, acquisition/tracking and pointing-jitter performance, and terminal-to-terminal cross-link closure. Own PHY layer verification: achieved data rates and throughput, BLER across all MCS points, and quantification of residual timing error, CFO/SFO, phase noise, and Doppler effects in a LEO channel. Own MAC -layer and network-layer verification: initial network entry, power control, link adaptation, scheduling, handover, and make-before-break continuity under representative constellation dynamics. Simulation, Emulation & Automation Direct the architecture of high-fidelity HITL frameworks that replicate orbital dynamics — delay/Doppler profiles, azimuth/elevation tracking, handovers, and real-time kinematics — using CATR/anechoic ranges, channel emulators, GNSS simulators, hexapods/positioners, and precision RF and optical reference instrumentation. Model constellation geometry, antenna ground projections, and SINR variation to predict and validate data-rate performance across latitudes, beam configurations, and orbital/launch phases. Lead the design, evolution, and continuous improvement of the verification SDLC across multiple teams: automated CI/CD pipelines for waveform, modem, and terminal regression; test-vector generation; instrument abstraction layers; and automated data reduction and analysis. Champion software and test engineering best practices — version-controlled test assets, TDD, code review, reproducible test environments, and telemetry-driven data analysis — and evangelize the use of data across teams to assess and measure impact. Contribute production-quality code and tooling in Python, C/C++, and MATLAB/Simulink for test automation, signal processing, and analysis; define performance KPIs (latency, throughput, link margin, algorithmic efficiency) and the methods used to measure and optimize them. Infrastructure, Anomaly Resolution & Operational Excellence Define and direct multi-year lab, chamber, and ground-station infrastructure roadmaps, including capital planning, vendor selection, procurement, and deployment of permanent, mobile, and field test capability. Lead anomaly investigations and root cause analyses on the most complex and ambiguous RF/optical, digital, and software-interaction failures, spanning commercial, open-source, and custom solutions; drive corrective and preventive actions to closure. Drive operational excellence initiatives across the organization, especially where processes, tooling, or test capability are slowing innovation or blocking delivery for other teams. Support on-orbit commissioning and flight operations, including test-as-you-fly validation, on-orbit performance characterization, and handoff of runbooks and operational procedures. Leadership & Influence Provide mentoring and technical leadership to engineers and projects across Blue through design reviews, technical forums, mentoring relationships, and setting of technical direction; be accountable for the technical accuracy of others' work through review. Guide the successful completion of major programs through formal technical leadership roles on project and test teams; direct and drive updates on schedule, budget, milestones, and risk for the systems you own. Develop and manage relationships across the company and with external partners, vendors, and standards bodies, often serving as organizational spokesperson and advisor to leadership and customers on advanced technical studies. Own technical documentation, verification reports, ICDs, and test plans/procedures, including release criteria for deliverables.
