Simulation and Support Equipment Group• Manage a team of developers producing hardware simulation and support equipment (SSE) software• Provide training for software developers unfamiliar with SSE architecture and infrastructure• Collaborate with SSE hardware team for integrated hardware and software deliveries of ground support equipment and test beds• Responsible for maintaining schedule of software deliveries, and ensuring delivery dates are met

Designs, develops, and modifies mission critical software for embedded real-time systems applications to control highly complex or specialized operations. Applications include software for spacecraft flight subsystems (command and data handling, attitude control, telecommunications, robotics, control systems or other functions); high level system behaviors (mode management, fault protection); flight instrument mission payloads on spacecraft, aircraft, balloons, or other delivery vehicles; and Electrical Ground Support Equipment (EGSE) for spacecraft simulation and test environment. Utilizes extensive embedded system expertise to understand the needs of the customer, translates needs into requirements, develops prototype software applications, interfaces with other subsystems and customers and designs, implements, tests and delivers highly reliable software applications. Involved in entire life-cycle of system, including proposals, planning, development, deployment, maintenance and operations. Has software design capability for an embedded environment including applicable microprocessor/microcontroller architectures, processor performance considerations, start-up and initialization, memory usage, sensor/actuator interfaces, data transport and storage, and hard real time deadlines. Understands and accommodates restrictions imposed by the embedded environment including timing and margin constraints, processor performance limitations, memory limitations, and communication bandwidth constraints.
