Full time Backend Developer .NET API

Build and maintain SvApi, the API layer that connects Silvervine’s insurance platform to outside systems on the LAAIR team.

Develop and maintain REST endpoints in C# and ASP.NET Core across the service set, including rating, policy, claims, motor-vehicle records, VIN lookup, loss history, flood risk, and document generation
Integrate third-party insurance data providers by reading vendor schemas or documentation, modeling responses, and mapping them into internal models
Own response mapping and projections, deciding which fields the API exposes to partners and ensuring fields do not silently go missing
Write unit and integration tests for your work before it is reviewed
Implement cross-cutting concerns service-by-service, including request validation, global exception handling, security headers, and caching
Reduce duplication by moving repeated logic into shared libraries, consolidating common serialization and filtering into a core package service by service
Debug production integration failures by reviewing logs, comparing against legacy platform behavior, and identifying the root cause
Participate in sprint ceremonies, including planning, refinement, standup, and retrospective

Working knowledge of C# and the .NET ecosystem (including .NET 6 or newer)
Comfort with REST APIs, including experience calling APIs and ideally building one
Serialization experience with JSON and/or XML, with awareness that mapping between models is where issues often appear
Sufficient SQL knowledge to write joins, use GROUP BY, and reason about incorrect row counts
Familiarity with git and a pull-request workflow
Ability to communicate early when something is unclear, rather than leaving confusion until later
Zero to three years of professional experience, or a relevant degree, or a portfolio showing similar work

Join the LAAIR team that owns SvApi, the API layer between the insurance platform and external systems it depends on
Support workflows where, for example, an agent requests a home or auto quote and SvApi retrieves motor-vehicle records, prior loss history, property valuations, and credit scores from data vendors, then turns that data into a rate
Focus heavily on integration work involving third-party APIs outside of your control, mapping their responses into internal models, and diagnosing failures when vendors change behavior
Start with well-scoped tasks reviewed by a senior developer; as you learn the domain, the scope grows
Role expectations: you will be new; prior insurance knowledge is not required

ASP.NET Core Reflex Endpoints experience
Azure experience, including App Service, SQL Database, Service Bus, Application Insights, and DevOps pipelines
Experience with Entity Framework Core or Dapper
Test framework experience (xUnit, NUnit, or MSTest) through writing tests
FluentValidation or another request-validation library
OpenAPI / Swagger experience, either writing or consuming an API contract
Infrastructure as code exposure (Bicep, Terraform, ARM)
Prior exposure to insurance, financial, or other regulated-industry software
Any familiarity with legacy CFML / ColdFusion, since parts of the platform involved in integrations are built with it

Application includes three short questions; answer all three
Question topics: item you feel least prepared for in “What you'll work on” and what you would do in the first month; naming any unfamiliar items from “Nice to have”; and sharing a small piece of code you wrote plus one sentence on what you would change today
Silvervine uses AI tools and expects candidates to use them too; using an assistant is fine, but do not submit content you have not read
Everything you submit is yours to stand behind in the interview, and you may be asked about it
