Job description

Location: Sioux Falls, SD We are seeking a Staff Software Engineer to help develop customer-facing command-and-control software for mission-critical systems. This is a hands-on, full-stack engineering role for someone who thinks in systems, not just features. The successful candidate will lead the architecture and development of production-grade single-page applications and the backend services that support them, including real-time telemetry, operational data, and complex workflows.

Responsibilities

• Architect and implement core systems for complex, data-driven single-page applications.
• Design backend services, APIs, and data flows supporting real-time telemetry and operational workflows.
• Lead technical design for full-stack features, ensuring scalable and maintainable implementations.
• Establish engineering patterns, architectural standards, and code-quality practices.
• Make foundational decisions on application structure, service boundaries, and system integrations.
• Resolve performance, reliability, and maintainability issues across the stack.
• Conduct architectural and code reviews.
• Mentor engineers through clear technical discussions and constructive feedback.

Qualifications

• Bachelor’s degree in software engineering, computer science, or a related field, or equivalent relevant experience.
• 8+ years of engineering experience with a bachelor’s degree, or 6+ years with a master’s degree.
• Demonstrated experience designing and delivering significant production software systems.
• Strong full-stack capability, including frontend architecture and backend services.
• Ability to explain technical tradeoffs and architectural decisions clearly.
• Experience solving complex engineering problems in a disciplined, high-accountability environment.
• Ability to write software independently. Familiarity with AI-enabled development tools is welcome but not a substitute for engineering judgment.

Preferred Experience

• Python
• TypeScript
• Complex data visualization
• Design systems
• Operational or decision-support tools
• Real-time or mission-critical software environments

Work Environment

This role is primarily office-based. Strong preference is given to candidates available for onsite collaboration in Sioux Falls, South Dakota. Hybrid arrangements may be considered. Remote candidates will not be prioritized. The role may occasionally require work near production areas with noise, fumes, moving machinery, and varying temperatures. Reasonable accommodations are available for qualified individuals with disabilities.

Compensation & Benefits

• Health and disability insurance
• 401(k) match
• Flexible spending accounts and HSAs
• Employee assistance program
• Tuition reimbursement
• Parental leave
