As a Senior Software Engineer on the MCNA Dental EDI team, you will design, create, and maintain software that interfaces with clearinghouses, Medicaid agencies, and plan sponsors. As part of a small team, using technologies such as Lisp, Clojure, and MarkLogic, you will be responsible for the accuracy of our most critical data and solve difficult engineering problems in a distributed system with terabytes of data while ensuring performance and scalability. This is a very data-focused software engineering role - heavy emphasis on data integrity and performance, not user interfaces. You will need to be a self-starter who is self-managed and eager to learn new technologies.

Primary Responsibilities:

Work independently to design, create, and maintain software components.

Propose and implement major system changes to improve the speed, accuracy, or maintainability of our EDI engine.

Implement new interfaces or adjust existing interfaces for new major customers, typically representing around 1 million members.

Determine software requirements by reviewing implementation guides and companion guides, and actively participating in meetings with all stakeholders.

Drive root cause resolution to reduce future incidents following best practices.

Ensure your code’s accuracy and performance using automated tests.

Define data flows and transformations using Common Lisp, Clojure, XSLT, xQuery, SQL, and MarkLogic.

Work with a variety of data formats including X12, XML, and TSV.

Work with a variety of databases including MarkLogic, Postgres, and Datomic.

Investigate errors to correct both the loading/transforming processes as well as any affected data.

Explore a large codebase to determine how existing code should evolve to meet new requirements.

Investigate problems that are not yet well understood and propose solutions.

Required Qualifications:

3+ years of progressive Common Lisp software development experience

5+ years of progressive software application development experience

2+ years of experience working across a large codebase with responsibility for upstream and downstream system interactions and dependencies
