Senior Software Engineer- Full Stack

About the Role:

As a Senior Software Engineer, Full Stack, you will design, build, test, and ship end-to-end product features across Crexi’s platform—owning work from UI through APIs and data. You’ll operate with a strong product mindset, partnering closely with Product and Design to turn customer needs into simple, scalable solutions. You’ll also leverage modern AI coding tools to accelerate delivery while maintaining a high bar for code quality, security, and maintainability. 

 

What You'll Do:

A typical day may include: 

• Design, develop, deploy, and maintain full-stack web applications using TypeScript across front-end and back-end systems. 

• Build high-quality, customer-facing user interfaces with modern web frameworks (Angular preferred). 

• Translate designs into responsive, modern experiences across devices (desktop, tablet, mobile). 

• Build and maintain backend services and APIs (Node.js/TypeScript), including: 
  • Scalable API design (REST and/or GraphQL) 
  • Authentication/authorization patterns 
  • Data modeling and database schema design 
  • Performance, reliability, and concurrency considerations 
• Rapidly prototype, iterate, and ship user-facing features—balancing speed with long-term architectural integrity. 

• Leverage AI coding tools (e.g., Cursor, Copilot) for scaffolding, refactoring, test generation, and debugging—while critically reviewing AI output for correctness, security, and performance. 

• Participate in (and often lead) code reviews, raising the bar on quality, readability, and security across the stack. 

• Troubleshoot complex production issues with a focus on observability, performance tuning, and prevention. 

• Identify opportunities to improve developer/agentic experience, processes, and platform foundations (tooling, CI/CD, testing, architecture patterns). 

• Collaborate cross-functionally with Product, Design, and Engineering to drive measurable impact for customers. 

• Mentor junior engineers through pairing, feedback, and technical guidance; contribute to a culture of pragmatic, user-focused engineering. 

• Author and maintain clear technical documentation for features, APIs, and system behavior. 

 

Qualifications:

• Bachelor’s degree in Computer Science or related field, or equivalent practical experience. 

• 5+ years of professional software development experience in production environments with meaningful scope/ownership. 

• 2+ years of hands-on TypeScript experience across front-end and back-end contexts (strong preference for deeper expertise). 

• Proven full-stack capability: you have shipped features end-to-end (UI → API → data) and can own production outcomes. 

• Strong experience building modern web UIs using TypeScript (Angular preferred; other modern frameworks acceptable). 

• Strong backend fundamentals, including API design, data modeling, and performance considerations. 

• Experience with source control and collaborative workflows (GitHub/GitLab), including code reviews and CI/CD basics. 

• Demonstrated use of AI coding assistants (e.g., Copilot, Cursor) in a professional workflow—without compromising quality. 

 

Who You Are:

• Self-starter who independently drives outcomes, owns success metrics, and follows through. 

• Strong product thinking: you can balance customer experience, technical feasibility, and maintainability. 

• Excellent communication skills—able to explain tradeoffs and align stakeholders. 

• Strong debugging skills across the stack (UI, APIs, data), with a calm, structured approach to incident response. 

• Security- and privacy-minded engineering approach (safe defaults, least privilege, secure coding practices).
