Lead cross-functional experimental programs to improve the performance and scalability of superconducting qubit systems. Design and execute experiments, identify and mitigate technology gaps, propose technical directions, shape the roadmap, and own delivery of key quantum hardware technologies. The role requires deep experience with cryogenic systems, RF and time-domain measurements, superconducting quantum devices, quantum science, technical leadership, and Python.

Designs and builds mechanical hardware for manufacturing, animal studies, and clinical trials. Develops precise, high-throughput, reliable test systems and owns designs from concept through prototyping and clinical deployment. Collaborates with electrical, software, ultrasound, and clinical teams. Requires strong engineering fundamentals, CAD and rapid prototyping expertise, a mechanical engineering degree or equivalent experience, exceptional technical contributions, integrity, and sound professional judgment.

Designs, analyzes, tests, and implements electrical systems and components for defense applications including radar, RF, antennas, communications, signal processing, and machine learning. Responsibilities include requirements derivation, system modeling and simulation, feasibility studies, performance verification, technical documentation, component production, systems integration, and compliance with safety and performance standards.

Design, develop, test, deliver, and maintain performant, reliable, scalable software for Heliux’s core platform. Engineers solve complex technical problems end to end, influence platform architecture and technical direction, and work closely with manufacturing customers. Roles may support Product, Supply Chain, Manufacturing, Planning, or Sales OS modules.

Supports the design, development, validation, and continuous improvement of advanced ceramic manufacturing processes, tooling, and production methods. Responsibilities include NPI support, prototyping, process documentation, BOM and routing updates, CAM setup, machine troubleshooting, SPC and data analysis, root cause analysis, metrology, GD&T interpretation, and collaboration with manufacturing personnel to improve quality, productivity, and process capability.

Develop and maintain C/C++ applications on Linux, using command-line toolchains and CI/CD pipelines to compile, test, containerize, and deliver software artifacts. Apply Git, code reviews, static analysis, troubleshooting, design patterns, architectural principles, and SOLID practices to build scalable systems. Collaborate with development, operations, security, and business teams to ensure reliable, secure software delivery.

Design and optimize food and beverage operations and packaging processes. Build databases, dashboards, and KPI reports; perform statistical and prescriptive analysis; collaborate with R&D, Operations, Quality, Marketing, and suppliers; evaluate packaging materials for safety, quality, and sustainability; develop specifications and testing protocols; implement automation and efficiency improvements; and troubleshoot production issues.

Performs mechanical engineering design and analysis supporting the Susquehanna nuclear power station. Maintains design bases, develops calculations, evaluates plant systems, resolves technical issues, supports modifications, coordinates with site teams and vendors, reviews industry operating experience, and delivers compliant engineering products. The role may be Engineer, Senior Engineer, or Principal Engineer depending on experience and includes participation in emergency response organization functions.

Designs, implements, and deploys customer-specific technical solutions for complex financial workflows. Responsibilities include gathering requirements, designing architectures, building integrations, data pipelines, APIs, and application workflows, troubleshooting technical issues, and collaborating with product and engineering teams. The role combines coding, financial workflow analysis, customer communication, rapid prototyping, and identifying reusable product capabilities in a fast-moving startup environment.

Develop and execute test strategies for electromechanical, robotic, camera, sensor, and embedded hardware systems from prototype through production. Build test fixtures and stations, automate testing, analyze failures, troubleshoot integrated hardware, validate camera and sensor performance, support product bring-up and certification testing, and maintain detailed engineering documentation. Collaborate with electrical, mechanical, software, manufacturing, and quality teams to improve reliability, manufacturability, and test coverage.
