Senior Software Engineer- Full Stack

About the role

About Crexi

Commercial real estate is one of the largest asset classes on earth and one of the last to go digital. Deals still get done over email threads, PDFs, and relationships nobody can search for. Crexi is the exchange betting that doesn't have to be true anymore: we're building the platform where an entire industry finds, evaluates, and closes deals, and we're betting hard on AI to get there faster than anyone thought this industry could move. There's no playbook for turning a trillion-dollar, relationship-driven industry into a modern marketplace which means the people building it get to write it.

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.
