The Opportunity

The Senior Software Engineer is responsible for the design and implementation of major components of our lending origination, servicing, and reporting system. This is done through both hands-on development and mentoring / leading more junior members of the team. Our technology is a microservices architecture purpose-built for AWS cloud on an open-source stack using Python, React, DynamoDB, MySQL, Linux, Docker, Large Language Models, and Generative AI.

What You Will Do

• Work fully embedded in a development team, including attending stand-up meetings and substantially overlapping your work day with Eastern time zone hours (minimum overlap of 9am to 1pm ET).
• Work with the engineering, product, and data science teams and business stakeholders to create, innovate, and implement effective solutions that support online lending and servicing.
• Lead the design and development of new software products and major enhancements to existing software for clients and business partners.
• Analyze, vet, and review code that supports standard database and software solutions on an enterprise software platform hosted on AWS.
• Leverage generative AI tools and LLMs to accelerate development, improve productivity, and build innovative product features.

Who You Are

• 5+ years building and running production Python services, including ownership through deployment, monitoring, and production incidents.
• 5+ years designing and consuming REST APIs in a microservices architecture, with clear reasoning about service boundaries, versioning, and backward compatibility.
• Hands-on experience with AWS beyond "it runs there": containerized compute (ECS/EKS or Lambda), queues and messaging (SQS/SNS), S3, and CloudWatch or equivalent observability tooling.
• Relational data modeling and query tuning in MySQL, plus practical DynamoDB access-pattern design.
• Automated testing (pytest or similar), CI/CD pipelines, incremental rollout, and troubleshooting on Linux.
• Demonstrated technical leadership: has led a multi-engineer effort end to end, authored the design, reviewed others' work, and grown less experienced engineers.

What Makes You Special 

• Event-driven and asynchronous architectures (SQS/SNS, Airflow or similar orchestration).
• FastAPI and SQLAlchemy ORM.
• Docker, and infrastructure as code (Terraform or CloudFormation).
• React or another modern frontend framework.
• Building with LLMs and GenAI: prompt design, evaluation, RAG or agentic workflows, and working effectively alongside AI coding agents.
• Financial services applications and regulated data, especially lending or payments.
• Security practices for web applications: authn/authz, OWASP basics, secrets handling.
