The company has raised more than $230 million and is scaling a high-caliber engineering organization.


The opportunity


We are hiring a Senior Software Engineer to own backend-heavy product and platform work from design through production. You will solve technically demanding problems at enterprise scale, ship with high autonomy, and use modern AI coding tools as part of an engineering culture where AI-generated code is rigorously human-reviewed.

• Own complex features end to end in a fast-moving product environment.

• Build and scale backend systems that support billions of dollars in mortgage transactions.

• Design reliable distributed systems for complex federal, state, and agency requirements.

• Use AI coding tools to accelerate development while maintaining a high bar for correctness and review.

• Partner across product, infrastructure, and platform teams based on your strengths and company priorities.

• Contribute to architecture, system design, technical decision-making, and engineering standards.


What we are looking for


• 3 to 10 years of backend-leaning software engineering experience.

• Experience at a product-focused software company with a strong record of ownership and progression.

• Excellent data structures and algorithms fundamentals, including the ability to solve coding problems without AI assistance.

• Experience designing large-scale distributed systems.

• Strong product judgment, communication, and comfort operating in a high-growth startup environment.

• Daily proficiency with AI coding tools such as Cursor, Copilot, Claude Code, or similar tools.


Helpful experience


• Python, React, Docker, Kubernetes, or Google Cloud Platform.

• Fintech, financial infrastructure, or other complex transaction systems.

• Experience scaling systems and teams through rapid customer growth.


Location and compensation


• Full-time and remote within the United States.

• Optional office access in New York City and San Francisco.

• Base salary: $210,000 to $300,000, depending on level and experience.

• Competitive equity and comprehensive benefits, including 12 weeks of paid parental leave.

• Visa sponsorship and transfers, including OPT and H-1B transfers, may be supported.


Interview process


The process includes a recruiter conversation, a live data structures and algorithms coding interview without AI tools, a behavioral interview, and a remote final panel covering system design, AI-assisted coding, and a technical project deep dive.
