About BigRentz

BigRentz is a technology-driven equipment rental marketplace modernizing how construction professionals rent heavy equipment. We’re building SiteStack, our next-generation SaaS platform that is reshaping the industry.

We need a Senior Software Engineer who is exceptional at practical, day-to-day React development paired with solid back-end skills in .NET Core. If you’ve ever debugged a messy reducer, restructured state management to eliminate uncontrolled input warnings, or built scalable front-end features under tight deadlines, you’ll feel right at home here.

What You’ll Do

• Design, develop, and optimize full-stack applications using React.js (with Redux), C#/.NET Core, and PostgreSQL
• Build front-end features that actually work in production—with clean state management, reusable components, and performance in mind
• Collaborate with product, design, and QA to ship practical, maintainable features quickly
• Diagnose and fix real-world React issues (controlled vs uncontrolled inputs, reducer bugs, async state updates)
• Mentor peers through code reviews and hands-on problem solving
• Contribute to architecture discussions, CI/CD pipelines, and SaaS scalability strategy

What We’re Looking For

• 8+ years professional software development experience
• 4+ years of deep, hands-on React (your GitHub or work history shows real production React code)
• Proficiency with Redux or other state management libraries
• 4+ years modern C#/.NET Core experience
• Comfort with PostgreSQL and relational database design
• Strong communication skills—able to explain technical decisions clearly and collaborate across teams
• Ability to thrive in a remote, distributed environment with minimal hand-holding

Bonus Skills (not required)

• Domain-Driven Design (DDD) or event-driven architecture
• Experience with event sourcing or large distributed systems
• Familiarity with CI/CD pipelines (GitHub Actions, Azure DevOps, etc.)

What We Don’t Care About

• We are not testing you on data structures & algorithms (DSA) puzzles
• We value practical React expertise over LeetCode skills—if you’ve solved front-end state problems in production apps, that’s exactly what we want

Hiring Process

1. Phone Screen – quick alignment on experience and expectations
2. Tandem Technical Video Interview – live React coding (not trick questions)
3. Panel Interview – technical + cross-functional discussions
4. Topgrading References – 3–5 candidate-initiated reference calls
5. Final Chat & Offer

Why Join Us

• Fully remote within the U.S.
• Starting salary $120K + benefits
• Collaborative, pragmatic engineering culture (we care about what works)
• High-impact role shaping a core SaaS product used nationwide
