• Collaborate in a small Agile team setting
• Work independently
• Work with stakeholders to gather and develop requirements driven by science and engineering concerns
• Adapt to changing requirements
• Organize multiple projects and estimate work
Qualifications:
A BS/BA in Computer Science, Physics, or a related scientific or technical field and 5 – 8 years of software development experience, including:
• Substantial experience developing complex, object-oriented applications in C++ or a similar language
• Excellent software design skills
• Excellent problem solving and debugging skills
• Good testing practices
• Good version control practices
• Good written and verbal communication skills
• A helpful and collaborative team-player mentality
• Agile development practices
• Experience with orbital mechanics or spacecraft operations is a plus, but not required.
The position level and salary are commensurate with education, skills and experience.
Our excellent benefits include:
• Employer retirement contribution – direct STScI contribution of 10% of your salary from your first day
• 12 days sick leave, 24 days’ vacation, and 10 paid holidays
