Job Details

5+ years of backend development with expert-level C# and .NET 8+

Familiarity with Svelte, TypeScript, and frontend development
Familiarity with Auth0 and OktaFGA
Exceptional communication skills
Proven ability to independently drive high-impact initiatives to completion

Architect and implement sophisticated legal domains using Domain-Driven Design (DDD), defining bounded contexts, aggregates, domain events, and a shared ubiquitous language.
Model resilient, event-sourced systems with Marten, leveraging multi-document sessions, projections, and tenanted document storage in PostgreSQL.
Design and deliver asynchronous, idempotent message handlers using Wolverine, with built-in retry policies, dead-letter queues, and full observability.
Optimize PostgreSQL performance under high-throughput workloads using indexing, partitioning, and query tuning.
Drive end-to-end feature ownership—from domain modeling and REST API design to CI/CD automation, observability, and production monitoring.
Establish and enforce engineering excellence through code reviews, architectural decision records (ADRs), and comprehensive test coverage (unit, integration, contract).
