Senior Full Stack Software Engineer

Job Description The Role: As a senior engineer, you will help design, build, and safeguard the quality of applications across the GM's Product Validation, Safety & Quality IT (PVSQ) organization, which spans regulatory compliance, safety systems, and quality engineering used across vehicle programs. Depending on your strengths, you may lean toward building end-to-end features across the stack (Quarkus or Spring Boot services, a Next.js/React portal, a relational database, and a Databricks lakehouse) or toward the test automation and quality engineering that keep those systems reliable. You will have the opportunity to work hands-on writing software or solutions, based on detailed requirements and system specifications. Using sound, repeatable, industry standard methodologies, you will support the PVSQ organization responsible for developing Nextgen applications. As part of development activities, we will update existing software and/or develop new software solutions to target specific business obstacles. A repeatable, systematic, and quantifiable approach to the development process will also be applied along with the use of appropriate methodologies. As a coach/mentor, you will provide feedback on the software being developed to software developers. Ensure code alignment with design patterns/frameworks by working closely with architects and data scientists. What You'll Do: • Design and maintain back-end microservices in   Java (Quarkus   or Spring Boot ) , exposing both   REST and GraphQL  APIs with well-defined, versioned contracts and shared DTOs. • Build responsive front-end features in the   Next.js / React  portal using   TypeScript  and   Apollo  for GraphQL data access. • Develop and support   Databricks  data workflows (Unity Catalog, Delta tables, and the medallion pattern) that feed regulatory reporting and dashboards. • Evolve the transactional relational schema (PostgreSQL or Oracle) safely, writing versioned   Liquibase  changesets that ship through the same pipeline as application code. • Produce clean, well-documented, testable code that aligns with the team's design patterns, frameworks, and standards. • Conduct thorough code reviews and write   unit, integration, and end-to-end tests  (TestNG, Selenium, cross-browser via BrowserStack) that gate every release. • Diagnose and resolve issues across services, the portal, and data pipelines, using observability tooling (Datadog / App Insights). • Work within the CI/CD pipeline (GitHub Actions, security scanning, promotion dev → test → prod) and help keep   main releasable at all times. • Translate business and regulatory requirements into executable development work: break them down, shape the technical approach, and drive it through to delivery in partnership with stakeholders and BAs. • Lead and drive software design for scalability and reusability across the full stack, from the UI down to the database structure. What You'll Need: • Bachelor's degree in Computer Science or a related field, or equivalent professional experience. • 7+ years building and shipping production software , with strong recent depth in   Java / JVM  (Quarkus or Spring Boot). • Demonstrated   full-stack  capability: comfortable owning a feature from a   Next.js / React / TypeScript  front end through a Java service to the data layer, not backend-only. • Proven ability to take a business requirement all the way to running software: owning the end-to-end design (UI through service to database structure) with scalability and reusability in mind, rather than only implementing predefined tickets. • Hands-on experience designing and operating   RESTful and GraphQL APIs , including contract/versioning discipline and API security best practices. • Solid experience with a   relational
