We are a medium-size company having been in business for over 25 years with never having a layoff and very low turnover 2–4% per year. Our company is very dedicated to a great work/life balance.

We are looking for passionate Software Developers to design and develop software solutions for state-of-the-art safety-critical systems in the areas of Avionics and Space Exploration to join our team. Positions include full-time or hourly, Medical/Dental/Vision benefits, and a 12% company paid individual IRA contribution for full-time employees. This position is located on-site in St. Louis.

Salary Range: $75,000-$145,000 DOE

Experience Required:

Due to compliance with U.S. export control laws and regulations, candidate must be a U.S. Person, which is defined as, a U.S. citizen, a U.S. permanent resident, or have protected status in the U.S. under asylum or refugee status or have the ability to obtain an export authorization.
Bachelors or advanced degree in Computer Science, Computer Engineering, Electrical Engineering, Computer Systems Engineering, Mathematics, or equivalent development experience.
Avionics software development experience including DAL A or LOR Level 1 certification experience is required.

About Performance and Talent Tier:

Performance Software and its sister company, Talent Tier, are engaged in the design of Real-time Embedded Software and Hardware. This includes Avionics and Space Exploration applications such as Synthetic Vision Cockpit Displays, Flight Management System Guidance and Navigation, Platforms, and Datalink Applications. Our customers are both Commercial and Defense-related avionics and rocketry suppliers/manufacturers. Performance Software has been in business since 1998; we were awarded INC Magazine 5000 Fastest Growing Companies and Best Places to Work for multiple years. Both companies have locations in Phoenix, AZ, New Orleans, LA, Grand Rapids, MI, Clearwater, FL, Bothell, WA, Cedar Rapids, IA with other remote employees across the states.

Why Performance or Talent Tier?

Our foundation was built by implementing the characteristics from large companies that we liked and eliminating the characteristics that we did not. Without the archaic practices from larger organizations, we fully embrace the culture of clear accountability, a positive attitude, transparency between every department, and productivity over the clock. This builds trust between management and employees, which provides us with our greatest strengths as an organization, flexibility, and work life balance.

Competitive Benefits:

Our full-time team members receive competitive salaries plus a contribution, totally paid for by our company every paycheck to an individual IRA equal to 12% of your salary. Flexible hours. Our team members are provided health/dental/vision insurance coverage plus STD/LTD coverage, separate paid sick time and vacation days, and major holidays. Hourly employees are paid a very competitive rate with medical/dental/vision benefits available.
