About Us:
Friday Harbor is a modern AI mortgage underwriting platform. It helps lenders
identify problems in a loan file upfront, resolving potential issues earlier,
and assembling clean, complete, and compliant files from the start.
We’re a Seattle-based startup backed by top-tier investors (Abstract,
Mischief, Wischoff, AI2 Incubator, CoFound) and trusted by leading lenders
across the country, including several of the top-25 lenders in the country.
While our headquarters are in Seattle, our engineering team is fully remote
with quarterly off-sites. We offer flexibility and work-life balance while
still fostering a collaborative and creative team environment.
Join our team of 5 engineers to build the AI systems that are changing how
mortgages get underwritten. You'll work on LLM applications, integrate with
third-party mortgage platforms, develop new product features, and optimize
performance as we scale. The work spans cutting-edge AI (RAG, agentic
workflows) and practical backend engineering (APIs, integrations, data
pipelines).
Responsibilities:
* Architect and build scalable backend systems and APIs to support our AI-powered mortgage underwriting platform as we scale to meet rapid customer growth.
* Design and implement integrations with third-party mortgage systems (LOS platforms like Encompass, document providers, credit bureaus) and internal services.
* Build and optimize LLM-powered features using the latest in agentic AI systems and retrieval-augmented generation (RAG) to improve underwriting accuracy and automation.
* Own greenfield projects from concept to production while also scaling and refining existing systems to handle increasing loan volume.
* Optimize system performance, security, and reliability to maintain seamless operations as we process thousands of loans monthly for enterprise customers.
* Collaborate closely with our team of 5 engineers to define product features, technical architecture, and engineering best practices.
* Shape our technical culture and contribute to product strategy, bringing insights from both customer needs and emerging AI capabilities.
Requirements:
* 4+ years building scalable, high-performance backend systems. Expertise in a modern backend language required; must be comfortable working in Python or adapting swiftly.
* Bachelor's or Master's degree in Computer Science, Engineering, or a related quantitative/technical field.
* Strong problem-solving skills and the ability to design and implement efficient, maintainable software solutions.
* Excellent communication and collaboration skills, with the ability to work effectively in a fast-paced, small team environment.
* Comfortable with ambiguity and rapid iteration. Experience in startups or fast-moving teams is a plus.
Preferred Qualifications:
* Experience integrating LLMs into production applications or building AI-powered workflows.
* Production experience with SQL databases and familiarity with key-value stores like Redis.
* Experience with cloud platforms, preferably AWS, and containerization technologies like Docker.
* Experience working on financial technology or regulated industry systems.
We offer a competitive cash salary ($150-200k), significant equity
compensation, and a complete benefits package. Our compensation strategy is
geared towards attracting world-class talent and creating the possibility for
significant potential equity upside for our early employees.
This is your chance to learn and build cutting-edge AI systems, work with LLMs
and RAG, and make a lasting impact in the US housing industry!
