The Ground Systems Engineer will develop and verify satellite ground systems, engage in design trade studies, and support integration and testing processes against customer requirements.

Support design, analysis, requirements, and verification of satellite systems across the lifecycle. Assist in defining system performance, integrate technical parameters, optimize system architectures, and incorporate safety, reliability, maintainability, testability, human systems integration, survivability, security, and certification factors to ensure mission success.

Lead modeling, simulation, and mission design for satellite constellations. Develop EO/IR image processing, state estimation, and control algorithms. Architect CONOPS/DRMs, validate TPMs, and integrate simulation platforms with software and firmware teams to meet mission requirements.

Perform static and fatigue structural analyses and develop repairs for Boeing and MD-series aircraft. Collaborate with customers and internal teams to resolve AOG and fleet safety issues, produce substantiation packages, mentor engineers, and lead process improvements across the Customer Support Operations Center.

Support BCA/BGS by implementing and improving engineering processes. Assist SAW/CERT managers with E-UM and DAE appointments, track process change requests, conduct process reviews and quality control, collect and analyze engineering metrics, ensure regulatory compliance, and support RIM and training activities.

Design, develop, test, and maintain mission software (Java, C/C++, Python, ReactJS). Participate in agile lifecycle, system integration, architecture and requirements development, code reviews, debugging, verification/validation, and cross-discipline collaboration to meet safety, regulatory, and program objectives.

Design and develop RF and digital satellite communications systems, implement and verify multi-rate fixed-point signal processing algorithms, perform performance analysis and waveform development, conduct trade studies, support integration, test and HDL-level design/verification of payloads and spacecraft, and carry out detailed system design and verification activities.

Design, build, and optimize full-stack mobile and desktop web applications. Implement user interfaces, contribute to shared libraries, log and analyze metrics, use AI tools to accelerate development, and maintain high standards for code correctness, security, testing, performance, and scalability.

The Principal Software Engineer will design and implement systems for the advertiser experiences at Snap, lead technical vision, mentor engineers, and innovate on creator marketplace products.

As an RF Test Engineer, you will develop hardware and software test solutions for RF and wireless subsystems, create documentation, and validate these subsystems using automated test environments.

Design, implement, and optimize full‑stack web and mobile applications. Ship scalable, production‑ready features and UI components, improve performance and reliability, contribute to shared libraries, and use AI tools and metrics to inform development.

Lead schematic and PCB layout design, validate electrical systems (memory interfaces, power regulators, PDNs), perform hands-on failure analysis and debugging, provide technical leadership to junior engineers, and collaborate with firmware, software, thermal, and RF teams. Support supplier development builds with up to 20% international travel.

Lead a team of electrical engineers to develop next-generation AR products, manage projects, debug hardware issues, and collaborate cross-functionally.

Design, implement, test, deploy, and maintain audio software for AR devices. Collaborate across teams on embedded and HLOS audio architecture, signal processing, and audio ML. Participate in design/code reviews, debug and triage system issues, and drive audio roadmap execution.

Design, implement, and operate critical, highly scalable backend services (identity, friend graph, persistence).
