Beschreibung

• Design and build a greenfield multi-tenant policy gateway as a Nest.js/TypeScript service on the client's internal framework and AWS • Propose infrastructure changes as Terraform PRs for the client's DevOps team to apply • Implement webhook contracts with HMAC authentication, Vault-managed secrets, IP allowlisting, ISO-8601 date handling, and policy-version-at-date-of-loss selection • Build the tenant router and registry with composite resolution and defined failure behavior • Build source adapters with per-source authentication, timeouts, retries with backoff, and circuit breaking • Build tenant-specific SFTP landing zones, file validation and quarantine, and idempotent PostgreSQL policy-store loads with snapshot retention and freshness monitoring • Define the canonical policy model and shared canonical-to-target mapper • Lead the first partner's field-mapping review with the client's claims expert • Deliver per-tenant observability, including structured logs, metrics, Grafana dashboards, freshness alerts, and error-rate alerts • Create an onboarding runbook for adding additional tenants • Write isolation negative tests as a release gate • Run failure-mode drills and end-to-end walkthroughs in the client's sandbox • Support the client's security review and launch readiness • Collaborate directly with client engineers and domain experts across time zones, largely asynchronously

🎯 Anforderungen

• 5+ years of backend engineering experience with strong, recent TypeScript in production • Experience with Nest.js or a comparable dependency-injection-based Node framework • Experience building integration services or API gateways, including webhooks, signature-based authentication, retries, idempotency, circuit breakers, and third-party API adapters • PostgreSQL and relational data modelling experience; comfortable designing schemas and writing migrations • Experience with multi-tenant systems or another domain where data isolation is a hard requirement • Hands-on AWS experience with ECS/EKS or Lambda, SQS, S3, IAM, Secrets Manager or Vault • Ability to read and propose Terraform, even if another person applies it • AI-native way of working using tools such as Claude Code and Codex while reviewing every shipped line • Ability to scope ambiguous requests, write concise design notes, ask clients the right questions early, and deliver without heavy oversight • Fluent English and clear, proactive communication with technical and non-technical stakeholders • Some availability in PT timezone, not more than once a week • Insurance domain exposure, batch or file-based integrations, regulated-data experience, Grafana/OpenTelemetry-style observability, and prior consulting or client-facing delivery are nice to have

🏖️ Vorteile

• Fully paid licenses for Cursor, Claude Pro, etc. • Remote-first work arrangement • No filler meetings, no Jira bloat, and no micromanagement • Total autonomy over the workflow • Direct work with the CEO, CTO, VPs, and client leadership • Continuous growth and a strong knowledge-sharing culture
