Sr./Principal Software Engineer

ABOUT THIS FEATURED OPPORTUNITY

Our client is seeking a Sr./Principal Software Engineer to join a high-impact, revenue-generating engineering team responsible for applications that directly influence channel sales performance and business growth. This team owns critical platforms that support a significant portion of the company's sales operations through channel partners and is focused on building innovative solutions that drive measurable business outcomes.

This role is ideal for engineers who go beyond surface-level implementation and possess a deep understanding of how systems work at their core. The team values strong engineering fundamentals, architectural thinking, curiosity, and the ability to build scalable solutions from the ground up. You'll work across distributed systems, data integrations, and AI-powered applications while partnering closely with business stakeholders to rapidly prototype and deliver solutions.

The environment is fast-paced, collaborative, and highly visible, requiring engineers who can quickly understand complex business challenges, develop proof-of-concepts in days rather than weeks, and balance technical excellence with business impact.

THE OPPORTUNITY FOR YOU

As a Sr./Principal Software Engineer, you will design, build, and enhance large-scale applications that support both internal and external users while helping shape the next generation of AI-enabled solutions.

You will:

• Build and enhance AI/ML-driven applications and services
• Design and develop scalable distributed systems and data-intensive applications
• Work across multiple applications, architectures, and business domains simultaneously
• Partner closely with business stakeholders and product leaders to rapidly prototype and validate ideas
• Deliver proof-of-concepts within 1–3 days and iterate quickly based on feedback
• Solve high-volume, complex business challenges that directly impact revenue and channel partner performance
• Drive technical strategy and architectural decisions for mission-critical applications
• Leverage modern AI tools and development practices to accelerate engineering productivity and innovation
