Insurity’s Next Software Engineer II

We are seeking an experienced and highly capable Software Engineer II to join our Bridge product team. This role offers the opportunity to shape the future of a core Insurity platform by building new features, modernizing both frontend and backend components, and improving system performance. The ideal candidate will bring strong technical depth, collaborative instincts, and an automation mindset—along with a passion for using next-generation tooling to enhance delivery. You’ll play a key role in projects that include UI/API modernization, system integrations, and performance tuning, while also helping to adopt agentic workflows and internal automations that scale team impact.

What Our Software Engineer II Will Do

• Design, build, and ship features across a large .NET microservices suite; own your code from design through production.
• Own quality as part of engineering: write and maintain the automation needed to protect your services (unit, integration, contract, and targeted e2e). “Done” = coded, reviewed, tested, observable, deployed.
• Evolve APIs (REST/JSON; some SOAP): define clear contracts, enforce backward-compatibility with contract tests.
• Level up automation & CI/CD: improve pipelines, quality gates, coverage, and deployment reliability; reduce flaky tests and speed feedback loops.
• Operate what you build: add logs/metrics/traces, triage issues, root-cause and fix defects.
• Partner with QA on test strategy for your changes; QA is a collaborator, not a handoff.
• Lean into generative AI to go faster—safely:
• Use coding assistants (e.g., Copilot/ChatGPT/Replit) to draft code/tests/docs and verify outputs.
• Generate synthetic test data/cases from API contracts; summarize PRs, changelogs, and incidents.
• Build lightweight internal automations (e.g., PR reviewers, log triage helpers) under our governance.
• Document decisions and how to test/use your services.

     Within 6–18 months you will:

• Independently deliver simple → moderately complex enhancements end-to-end with solid estimates.
• Extend shared test/utilities as needed for your services (you’re not a test-framework team).
• Write concise technical docs for engineers, QA, support, and ops.

Who We’re Looking For

• 6–10 years building and shipping production services/features.
• C#/.NET (ASP.NET Core, Web API), SQL Server; microservices fundamentals (service boundaries, resiliency, observability).
• Quality-through-code (must-have): you routinely add unit/integration/contract tests for the code you ship; comfortable with Playwright/Cypress or Postman/Newman for targeted e2e; GitHub Actions/Azure DevOps/Jenkins for CI/CD and quality gates.
• Generative AI fluency (must-have): practical experience using coding assistants to accelerate delivery, crafting prompts, checking/ground-truthing outputs, and safely handling code/data (privacy & IP). Bonus: generating test data/cases, PR summaries, or simple internal automations; exposure to vendor AI features or no/low-code connectors
• Strong API design & documentation; SOAP familiarity is a plus.
• Solid engineering practices: OOP, SOLID, data structures/algorithms, Git, reviews, reproducible builds.
• Azure/DevOps exposure desirable (pipelines, IaC basics, monitoring).
• Automation mindset: linters/formatters, build/deploy scripts, DB migrations, scaffolding/code-gen.
• Clear communicator; collaborates well with Product/QA/Ops; change agent within 6–12 months.
• Nice to have: Insurance domain exposure (claims/policy/billing/underwriting).
• Hybrid role (we just built a brand-new office space!)

We are seeking a Full Stack Developer with exceptional communication skills to collaborate daily with our international clients in the US and Australia. This role requires not only technical expertise but also the ability to clearly articulate ideas, gather requirements, and maintain strong client relationships. Communication is the top priority.

The ideal candidate is passionate about technology, eager to learn and adapt to new stacks, and capable of delivering scalable, high-quality solutions across the stack.

Key Responsibilities

• Client Communication: Act as a daily point of contact for clients (US & Australia), ensuring smooth collaboration and requirement gathering.
• Backend Development:
• Design and implement REST APIs and GraphQL endpoints.
• Integrate secure authentication methods including OAuth, Passwordless, and Signature-based authentication.
• Build scalable backend services with Node.js and serverless frameworks.
• Frontend Development:
• Develop responsive, mobile-friendly UIs using React and Tailwind CSS.
• Ensure cross-browser and cross-device compatibility.
• Database Management:
• Work with RDBMS, NoSQL, MongoDB, and DynamoDB.
• Cloud & DevOps:
• Deploy applications on AWS / GCP / Azure (knowledge of at least one required).
• Work with CI/CD pipelines, monitoring, and deployment automation.
• Quality Assurance:
• Write and maintain unit tests to ensure high code quality.
• Participate in code reviews and follow best practices.
• Continuous Learning:
• Stay updated on the latest technologies and bring innovative solutions to the team.

Must-Have Skills
