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 desig
