Senior Full Stack Software Engineer (Backend-Focused)

Job Title: Senior Full Stack Software Engineer (Backend-Focused)

Type: 12-Month Contract-to-Hire

We are seeking a Senior Full Stack Software Engineer to join our e‑underwriting platform team, supporting rules‑based technologies that power multiple commercially offered insurance products. This is a senior role requiring deep backend expertise, strong testing discipline, and hands‑on CI/CD experience.

This position is backend‑heavy. Candidates must demonstrate senior‑level engineering depth; mid‑level profiles (4–7 years) are not a fit.

• Design, build, test, deploy, and support API‑based and web applications with a cloud‑first mindset
• Independently deliver REST API solutions from concept through production
• Develop and maintain robust unit and integration test coverage aligned to acceptance criteria
• Build and support CI/CD pipelines (Jenkins preferred; comparable tools acceptable)
• Collaborate within a Scrum team to solve complex, often ambiguous technical problems
• Apply industry best practices for coding, testing, security, and deployment
• Participate in peer code reviews and contribute to architectural and technical documentation
• Troubleshoot production issues and support new build deployments
• Identify, track, and remediate vulnerabilities while staying current on security threats
• Work closely with Architects, Product, Dev Ops, QA, and Engineering to deliver business value

• 10+ years of professional software engineering experience or a BS in Computer Science, Engineering, or related field
• 2+ years of recent full stack development experience on Java‑based platforms
• Strong backend development experience (Java, Groovy, Spring Boot)
• Proven experience executing unit testing and some integration testing (3+ years)
• Experience building and supporting CI/CD pipelines
• REST API design and development experience
• Experience with MongoDB
• Jenkins and Gradle experience (or equivalent CI/CD tooling)
• Ability to quickly learn new tools and technologies
• Strong problem‑solving skills and ability to work independently
• Clear, concise communication skills across technical and non‑technical audiences
