Description

  • Design and build a Nest.js/TypeScript gateway on the client’s AWS infrastructure, proposing Terraform changes for the DevOps team.
  • Implement webhook authentication, IP allowlisting, ISO-8601 date handling, and policy-version selection.
  • Build tenant routing, registry, source adapters, retries, timeouts, circuit breaking, and failure handling.
  • Develop SFTP-based batch ingestion with validation, quarantine, idempotent PostgreSQL loads, retention, and freshness monitoring.
  • Define the canonical policy model and map partner data into the claims platform schema.
  • Create per-tenant observability, dashboards, alerts, and onboarding documentation.
  • Write isolation tests, conduct failure drills and end-to-end sandbox walkthroughs, and support security review.
  • Collaborate asynchronously with client engineers and insurance domain experts across time zones, including occasional availability in PT time.

Requirements

  • 5+ years of backend engineering experience with strong recent TypeScript production experience.
  • Experience with Nest.js or a comparable dependency-injection-based Node.js framework.
  • Experience building integration services or API gateways involving webhooks, signature authentication, retries, idempotency, circuit breakers, and third-party APIs.
  • Strong PostgreSQL and relational data-modeling skills, including schemas and migrations.
  • Experience with multi-tenant systems or other environments requiring strict data isolation.
  • Hands-on AWS experience with services such as ECS/EKS or Lambda, SQS, S3, IAM, and Secrets Manager or Vault.
  • Ability to read and propose Terraform changes.
  • Experience using AI development tools such as Claude Code and Codex while reviewing all shipped code.
  • Self-directed approach to ambiguous requirements, design documentation, client communication, and delivery.
  • Fluent English and clear communication; insurance, batch integration, regulated-data, observability, or consulting experience is preferred.

Benefits

  • Fully paid AI tooling licenses, including Cursor and Claude Pro.
  • Remote-first work with high autonomy, minimal meetings, and no micromanagement.
  • Direct collaboration with company executives and client leadership.
  • Engineering culture focused on production systems, continuous growth, and knowledge sharing.
  • Full-time B2B engagement for candidates in the EU or Poland.
