Key Responsibilities :

Design & Development :

- Architect, build, and operate the full-stack services and user experiences that power loan origination, decisioning, and servicing our new Flagship Platform.

- Ship features end-to-end across our stack: Next.js on the front end, C# / .NET on the back end, PostgreSQL for data, and AWS ECS for infrastructure.

- Translate complex financial and operational workflows into clean, performant, well-tested code that holds up under regulatory scrutiny and production load.

API & Platform Integration :

- Lead integrations with credit bureaus (Experian, Equifax, TransUnion), dealer systems (DealerTrack, RouteOne), fraud and verification providers, and other third-party partners - including contract design, retry/idempotency strategy, and operational runbooks.

- Extend and customize our existing DEFI Solutions loan originations platform - configuring workflows, scorecards, rules, and decision flows, and developing services that integrate with DEFI via REST APIs and operational data store (MSSQL).

Feature Ownership :

- Collaborate directly with Product, Design, and business stakeholders on features from problem framing through production rollout and post-launch iteration.

- Drive observability, performance, reliability, and security across the services you own.

Code Quality & Engineering Practices :

- Set the patterns for testing, observability, security, and CI/CD that the rest of the team adopts.

- Leverage AI-assisted development practices and tools (Copilot, Cursor, Claude Code, and similar) to accelerate delivery without sacrificing quality.

- Run design reviews, give technical guidance, and help onboard the engineers who join after you.

Minimum Qualifications :

- Experience : 5+ years of professional software engineering experience.

- Full Stack Depth : Production experience building and operating modern web applications across both front and back end.

- Expert-level proficiency in C# / .NET and a modern React-based framework (Next.js strongly preferred).

- Data & APIs : Strong working knowledge of PostgreSQL (or a comparable relational database), RESTful API design, and SQL Server / T-SQL.

- Cloud & Infrastructure : Hands-on experience with AWS, including containerized workloads (ECS, EKS, Fargate, or similar) and Docker.

- Education : Bachelor's degree in computer science, Engineering, or related technical field, or equivalent experience.

Preferred Qualifications :

- Direct experience working with or building on DEFI Solutions, or equivalent commercial Loan Origination Systems.

- Auto finance, lending, or other regulated-industry domain experience.

- Experience with event-driven architecture and AWS messaging services (SNS, SQS, EventBridge, Kafka, or similar).

- Experience integrating ML-driven decisioning, scoring, or underwriting models into production systems.
