Job description

This is a remote position.

We are seeking an experienced software engineer to join a modern, cloud-native product team. The platform supports complex calculations and workflows including multi-entity and multi-jurisdiction processing within a scalable, enterprise-grade system.
You will contribute across a polyglot, multi-repo ecosystem spanning microfrontend UI, serverless APIs, dedicated calculation services, shared business logic libraries, and infrastructure-as-code. Engineers are expected to actively leverage AI coding assistants to accelerate delivery, improve code quality, and reduce ramp-up time in a complex domain.

Roles & Responsibilities:
  • Build and maintain features across the platform from React microfrontend screens to TypeScript serverless Lambdas and Fastify services
  • Contribute to the shared TypeScript libraries consumed by both frontend and backend, including its C# code-generation pipeline
  • Write and maintain unit, integration, and E2E tests using Jest, Playwright, and K6
  • Develop and deploy infrastructure changes using Terraform targeting AWS (Lambda, ECS, API Gateway, RDS/PostgreSQL, DynamoDB, S3, CloudFront, Secrets Manager)
  • Participate in GitLab CI/CD pipeline development and maintenance, including security scanning and Terraform deployment pipelines
  • Collaborate with architects and product teams to evolve async job patterns (imports, report generation), calculation service APIs, and data layer abstractions
  • Use AI coding assistants effectively writing precise prompts, reviewing AI-generated code critically, and applying outputs productively within a large existing codebase
  • Maintain and improve the legacy ASP.NET Framework 4.7.2 application as needed during migration

Qualifications:
  • Bachelor’s degree in computer science or related program and/or relevant experience.
  • Significant professional (7+ years) experience in software development with TypeScript/JavaScript (Node 18+), React 18, and working knowledge of C#/.NET (modern and legacy).
  • Experience building APIs using AWS Lambda & API Gateway and Fastify (with TypeBox and Swagger).
  • Experience with microfrontend architecture (e.g., single-spa), state management using MobX or React Query, and tools like Styled-components and Webpack; familiarity with AG Grid or SpreadJS is a plus.
  • Experience with GitLab CI/CD and familiarity with AWS SAM CLI and LocalStack for local development.
  • Experience with Terraform for AWS infrastructure and Docker/Docker Compose for local development.
  • Strong testing experience including Jest (unit and integration), Playwright (E2E), K6 (performance/load), and MSW for API mocking
  • Experience using AI coding tools (e.g., Cursor, Copilot, Claude) to support development, including prompt writing, reviewing outputs, and applying them for testing, refactoring, documentation, and code reviews, with awareness of security considerations.

Nice to Have:
  • Experience with OpenTelemetry instrumentation (Node.js services, React frontends via Grafana Faro)
  • Familiarity with Amplitude product analytics integration
  • Knowledge of ASC 740 tax provision concepts or corporate tax software
  • Experience with pa11y / accessibility testing
  • Security scanning tooling: GitGuardian, Veracode, Sonatype
  • Experience building or working with AI-powered testing or development agents (e.g. automated exploratory testing, LLM-driven code analysis)
