About the Company

We are an AI-native data and technology partner for private capital and healthcare. Founded in 2010 and headquartered in Warsaw, we work with leading PE firms, VC funds, and healthcare organizations to build proprietary data infrastructure, deploy AI solutions, and drive AI-native transformation. We've restructured our own company around AI - tools, policies, roles, delivery models.

The Opportunity

Our client is a US insurance carrier building a platform business on top of its own paper. The missing piece is a multi-tenant policy gateway, and it is the blocking dependency for the first partner's go-live at the start of 2027. You'll be the engineer who builds it. You'll work in a small pod with our tech lead and directly with the client's staff engineer, engineering manager and claims domain expert, in their codebase and on their AWS.

Responsibilities

  • Design and build the gateway service on the client's Nest.js-based internal framework and AWS, proposing infrastructure changes as Terraform PRs for their DevOps team to apply.
  • Implement the webhook contract: HMAC authentication in application code with secrets in Vault, IP allowlisting, ISO-8601 date handling, policy-version-at-date-of-loss selection.
  • Build the tenant router and registry with composite resolution and well-defined failure behaviour.
  • Build the source adapter framework - a common interface with per-source auth, timeouts, retries with backoff and circuit breaking.
  • Build the batch path: SFTP landing zones per tenant, file validation and quarantine, idempotent loads into a PostgreSQL policy store with snapshot retention and freshness monitoring.
  • Define the canonical policy model and the shared canonical-to-target mapper; take the first partner's mapping tables through review with the client's claims expert.
  • Ship per-tenant observability (structured logs, metrics, Grafana dashboard, freshness and error-rate alerts) and an onboarding runbook.
  • Write isolation negative tests as a release gate, run failure-mode drills and end-to-end walkthroughs in the client's sandbox, and support their security review.
  • Collaborate directly with client engineers and domain experts across time zones, largely async. Some availability in PT timezone would be required - not more than once a week.

What we offer

  • Unrestricted AI Stack & Premium Gear: Fully paid licenses for Cursor, Claude Pro, etc.
  • Total Autonomy (Remote-First): No filler meetings, no Jira bloat, no micromanagement. You own the workflow. We care about shipped systems in production, not logged hours.
  • Direct Impact: You'll work face-to-face with our CEO, CTO & VPs and directly with client leadership.
  • Frontier Engineering Culture: Build alongside elite engineers who are shipping systems that drive real business decisions. Backed by continuous growth and a strong knowledge-sharing culture.

Requirements

  • 5+ years backend engineering with strong, recent TypeScript in production; Nest.js or a comparable DI-based Node framework.
  • Experience building integration services or API gateways: webhooks, signature-based auth, retries, idempotency, circuit breakers, third-party API adapters.
  • PostgreSQL and relational data modelling; comfortable designing schemas and writing migrations.
  • Experience with multi-tenant systems or another domain where data isolation is a hard requirement, and the instinct to test it explicitly.
  • Hands-on AWS (ECS/EKS or Lambda, SQS, S3, IAM, Secrets Manager or Vault); able to read and propose Terraform even if someone else applies it.
  • AI-native way of working: you use tools like Claude Code and Codex as a core part of how you deliver, and you still read every line that ships.
  • Self-directed: able to scope ambiguous requests, write a short design note, ask the client the right question early, and deliver without heavy oversight.
  • Fluent English and clear, proactive communication with technical and non-technical stakeholders.

Nice to Have

  • Insurance domain exposure - policy administration systems, claims, FNOL, coverages and deductibles, MGA/carrier structures.
  • Batch or file-based integrations (SFTP ingestion, schema validation, quarantine patterns) or data-mapping heavy work.
  • Regulated-data experience: PII/PHI handling, HIPAA or SOC 2 controls, audit logging.
  • Grafana / OpenTelemetry-style observability.
  • Prior consulting or client-facing delivery.
