Senior Software Engineer- Full Stack

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.

Software Engineering, Commercial Real Estate, Artificial Intelligence (AI), Sales Closing Skills, Testing, Software Engineering, Application Programming Interface (API), User Interface/Experience (UI/UX), Product Design, Internet Application, * 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).

• Comfortable in ambiguity and fast iteration cycles; startup / zero-to-one experience is a plus.

• Health & Future covered. Medical, dental, and vision insurance, 401(k), FSA/HSA options, and Life & AD&D insurance.
• Set up right. Home-office reimbursement for remote employees.
• A winning team. A collaborative culture with team activities that bring people together.

The anticipated base salary range for candidates who will work in our Playa Vista, California location is $160,000 to $214,000. The final salary offered to a successful candidate will depend on several factors, which may include, but are not limited to, the type and length of experience applicable to the role and within the industry, education, geographic location, etc. Commercial Real Estate Exchange, Inc (“Crexi”) is a multi-state employer, and this salary range may not reflect positions that work in other states.

Crexi is an EEO Employer. Qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, sexual orientation, gender identity, disability or protected veteran status. Crexi will also consider for employment qualified applicants with criminal histories in a manner consistent with EEOC guidelines and applicable local law.

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.
