Ability to Obtain Public Trust

We are seeking a highly skilled Full Stack Engineer to build and modernize the NIH National Library of Medicine (NLM) Medical Subject Headings (MeSH) systems. The role centers on the MeSH Editing System (MEDIT) and the public MeSH Browser, and on migrating legacy ColdFusion/Oracle applications to a modern MEAN-stack architecture. The ideal candidate has deep hands-on experience across Node.js/Express, Angular/TypeScript, MongoDB, PostgreSQL/Oracle, and Elasticsearch, with extensive Selenium-based test automation and mature, security-conscious DevOps and data-pipeline practices.

What you Will Do

• Design, build, and maintain backend services in Node.js/Express, exposing secure REST APIs for MeSH editing and browsing.

• Develop responsive Angular front-ends (Angular Material, Bootstrap, RxJS) for record, concept/term, and tree editing and for public search.

• Implement and maintain automated test suites with Selenium/WebDriver (Protractor, Nightwatch); sustain cross-browser and regression coverage.

• Administer MongoDB; design schemas, indexes, and validation; optimize queries and manage backups; maintain PostgreSQL and Oracle databases as needed.

• Build and maintain Elasticsearch indexes; implement search, reindexing, and data synchronization across the document store and search layer.

• Develop and operate ETL pipelines that ingest MeSH XML and SQL exports; schedule and monitor full and incremental loads.

• Implement SSO/authentication (CAS, OpenID Connect, Passport) and apply security hardening and dependency-vulnerability remediation.

• Manage database schema changes (Flyway) and coordinate zero-downtime, multi-step data and code deployments.

• Modernize and migrate legacy ColdFusion/Oracle MeSH applications to the current architecture.

• Document architecture, runbooks, and SOPs; mentor junior engineers and contribute to standards and governance.

What you Will Need

• Must be able to OBTAIN and MAINTAIN a Federal or DoD "PUBLIC TRUST"; candidates must obtain approved adjudication of their PUBLIC TRUST prior to onboarding with Guidehouse. Candidates with an ACTIVE PUBLIC TRUST or SUITABILITY are preferred.

• Bachelor's degree in Computer Science, Information Technology, or related field.

• Minimum SIX (6) years of professional software engineering experience.

• Minimum Five (5) years of full-stack engineering experience across backend and frontend.

• Proficiency in Git-based version control (GitLab/Bitbucket) and collaborative development.

• Strong understanding of RESTful API design and integration.

• Strong backend development in Node.js (Express), including secure REST API design, session management, and middleware.

• Frontend development with Angular (16+) and TypeScript, using Angular Material, RxJS, and Bootstrap, plus core web technologies (HTML, CSS, JS).

• Database expertise including MongoDB (Mongoose schema design, indexing, performance tuning) and relational databases (PostgreSQL via Sequelize, Oracle PL/SQL).

• Search engineering with Elasticsearch (index design, query tuning, reindexing, and synchronization with the system of record).

• Test automation using Selenium/WebDriver - Protractor and Nightwatch - including cross-browser testing (Chrome, Firefox, IE) and end-to-end regression coverage.

• ETL and data-pipeline development: ingesting MeSH data from XML and SQL exports, transformation/denormalization, and scheduled (cron) full and incremental loads.

• Secure authentication/authorization (CAS, OpenID Connect/OAuth2.0, Passport) and web security hardening (Helmet, HSTS, dependency scanning).

• Database schema migration and versioning (Flyway) with zero-downtime deployment practices.

• Legacy modernization experience - migrating ColdFusion/Oracle systems to modern web architectures.

• Strong troubleshooting skills across Node.js, Linux, networking, performance, and observability.

• Must be eligible for a Public Trust clearance and complete federal background screening.

Nice-to-Have Skills

• Behavior-driven development with Cucumber/Gherkin feature specifications.

• Document generation and export to Word/Excel (docx) from structured records.

• FTP-based data exchange and large-file XML processing/splitting.

• Structured logging and monitoring (Winston, daily-rotate logs) and proxy/reindex tooling.

• CI/CD pipelines (GitLab CI) and automated packaging/deployment.
