The role requires independent software development, strong communication, comfort with AI tools, and occasional travel to customer sites while working onsite in Seattle.

Inspects and tests incoming materials, subassemblies, in-process radios, and finished products for quality and conformance. Documents defects, segregates nonconforming materials, collects data, and prepares reports, charts, and graphs to support quality improvement. The role requires visual inspection, test equipment use, interpretation of drawings and work instructions, strong Microsoft Office skills, precision, communication, and the ability to lift up to 30 pounds.

Test and certify new products against national and international safety standards. Responsibilities include evaluating products, interpreting test results, reviewing technical data, preparing certification reports, managing projects with mentorship, and supporting CSA Mark applications. The role is part of a graduate development program designed to build product safety engineering and project management skills.

Responsible for improving the reliability, availability, safety, and performance of production equipment, including CVD diamond-synthesis reactors. Duties include equipment troubleshooting, maintenance procedure development, commissioning, start-up planning, spare-parts specification, SOP improvement, training, data analysis, capital projects, and continuous improvement. The role serves as the in-house equipment expert and supports Maintenance Technicians while collaborating with Operations and external partners.

Build and ship software for AI applications supporting government decision-making. Responsibilities include developing guardrails, RAG and agent orchestration systems, data pipelines, evaluation infrastructure, anomaly detection, audit interfaces, and full-stack mission-data tools. Deploy and harden applications in secure, air-gapped, and cloud environments while working directly with government stakeholders.

Lead quality assurance for complex Calypso implementations by defining test strategies, plans, quality gates, and coverage. Build automated test frameworks using CATT, Selenium, JUnit, and Cucumber, integrating them into CI/CD pipelines. Coordinate integration, regression, performance, security, conversion, and user acceptance testing. Manage environments, test data, defects, traceability, metrics, reporting, and stakeholder communications across financial-services workflows.

Develop and test distributed storage software using C, Rust, and Python. Collaborate on architecture, design, code reviews, and pair programming; implement customer-facing features and system improvements; and debug complex test and production issues. The role involves distributed systems, fault tolerance, file systems, concurrency, replication, backup, and operating-system concepts under the mentorship of senior engineers.

Performs entry-level highway and roadway design for bridge and transportation projects under senior engineering supervision. Responsibilities include developing plans, specifications, cost estimates, geometric designs, drainage layouts, signage, striping, traffic control plans, feasibility studies, technical reports, quantity take-offs, and CAD details. Coordinates with survey, geotechnical, traffic, and environmental subconsultants; reviews design calculations and drawings; communicates with clients; and supports proposals. Occasional field assignments may be required.

Supports project engineering for new automated electromechanical systems in a manufacturing environment. Responsibilities include releasing designs into design control, sourcing components, managing purchasing and vendors, reviewing drawings and designs, identifying cost-saving opportunities, and maintaining project schedules. The role also requires compliance with quality and safety systems, analysis of machining and materials considerations, and collaboration with senior engineers across concurrent projects.
