Senior Software Engineer - Lisp

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.


You'll enjoy the flexibility to work remotely* from anywhere within the U.S. as you take on some tough challenges.


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.


You'll be rewarded and recognized for your performance in an environment that will challenge you and give you clear direction on what it takes to succeed in your role as well as provide development for other roles you may be interested in.


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


• Proven ability to work in a fast-paced environment while maintaining adherence to standards and best practices


• Proven ability to solve difficult data integrity challenges, such as those encountered with message queues, multiple databases, or network file transfers


• Proven ability to adopt new technologies quickly
