Serve as the product quality representative across new product development: develop program quality strategies, perform risk assessments (FMEA), validate MBSE/SysML models, chair MRB, ensure manufacturability and design-for-excellence, support qualification and transition to production, and drive quality decisions across stakeholders to prevent defects and delays.

Support materials and process engineering for aerospace hardware: select and evaluate materials/processes, plan and run tests, analyze data (SEM/EDS, FTIR, XRF, thermal, mechanical), review drawings, produce reports, and consult with engineering and production teams. On-site, lab, and production floor work with emphasis on meeting design and contractual requirements.

Design, build, and deploy modern frontend web interfaces using HTML5/CSS3, JavaScript frameworks, and responsive design. Consume RESTful APIs, ensure Section 508 accessibility, work in agile/SAFe teams, use Git/GitHub, create views in full-stack frameworks, and support CI/CD and containerization practices. Mentor peers and rapidly learn new tools.

Senior frontend engineer responsible for building responsive, accessible web interfaces using modern HTML/CSS/JavaScript frameworks, consuming RESTful APIs, working in agile teams, and supporting CI/CD and containerization workflows.

Support operational strategic planning, collect and analyze project scope, manage capital equipment selection and commissioning, perform factory and value-stream analysis with simulation tools, improve forecast databases, present to executives, lead small project teams, and collaborate across departments to support manufacturing and facilities growth.

Support spacecraft primary and secondary structure design from proposal through test and verification. Perform CAD modeling and drawing generation with GD&T, basic hand structural analysis, requirements development, DFx/DFT, risk management, and subcontract technical oversight. Coordinate with subsystem teams, external customers, payload and launch providers, and maintain on-site presence and predictable schedule.

Lead and execute spacecraft assembly, integration, and test (AI&T) campaigns; define test strategies and AI&T flows; manage facilities, GSE, cost/schedule estimates; author proposals; mentor engineers and technicians; ensure quality, risk mitigation, and operational success in cleanroom and lab environments.

Lead technical authority for on-orbit spacecraft covering mission lifecycle: mission design, ground segment design, autonomy and fault detection, simulation and testing, launch and early orbit commissioning, and day-to-day and anomalous on-orbit operations. Serve as focal for customers and leadership during critical mission activities.

Design, build, and maintain Airflow-based automation pipelines and services to move files, run scheduled FTP jobs, validate and modify data, monitor application health, parse logs/emails, implement robust error handling and observability, and integrate API-driven systems to reduce manual operational work.

Provide on-site third-level automotive technical support and diagnostics to GM dealers, resolve escalated Techline cases, reduce repurchases/warranty expense, train dealership staff, evaluate service readiness, report field product issues, and support regional wholesale and legal matters. Requires extensive dealership repair experience and frequent territory travel.

Lead technical strategy and architecture for Affirm Bank's cloud, data, vendor integrations, and operational tooling. Design, build, and operate high-stakes systems end-to-end, own incident response, vendor selection, and the Bank↔Affirm Inc integration boundary. Ensure examiner-ready documentation, compliance, reliability, and observability while mentoring engineers and pushing AI-assisted engineering practices to increase velocity and product safety.

The Principal Engineer will lead technical direction across multiple teams, design architecture for financial systems, mentor engineers, and drive multi-year transformations in the Money Group.

As a Staff Software Engineer, you'll design, build, and test Gusto's core platform services, mentor engineers, and collaborate with various teams to solve complex engineering problems.

Lead mission systems analysis and modeling to characterize performance of complex space/air/ground architectures. Develop tools and algorithms, produce analysis reports and presentations, support proposals, and collaborate with cross-functional teams to set system and component requirements.

The Backend Software Engineer will develop data ingestion pipelines, implement observability tools, and provide technical support while improving team collaboration.

Design, implement, and maintain software test capabilities for tactical systems. Perform full software lifecycle tasks—requirements, architecture, design, code, test, integration, documentation—and integrate test equipment and emulation infrastructure. Develop automated tests for embedded Linux, C/C++, Python and support containerized deployments. Collaborate across teams, maintain on-site presence, and support lab and production environments for mission-focused systems.

Perform board- and box-level electrical test and troubleshooting for electronic assemblies, design test fixtures and procedures, document results, and develop basic test automation scripts (Python/Ruby). Support qualification, verification, milestone reviews (PDR/CDR), and collaborate with technicians and cross-functional teams to meet schedules and resolve issues.

The role involves supporting spacecraft operations, maintenance, and testing. Responsibilities include performance analysis, telemetry trending, and collaborating on mission operations products.

Lead and perform radiation analysis and engineering for EEE parts and circuits on spacecraft. Conduct TID, SEE, DDD, and ELDRS analyses and test campaigns; review schematics and part lists for radiation compliance; develop test plans; coordinate with design and program teams; generate radiation analysis reports and document reviews. Interface with subcontractors and present radiation risks at program milestones.
