About the role

  • Visit PeopleLoop.com http://PeopleLoop.com or follow us on LinkedIn https://www.linkedin.com/company/peopleloopinc/ to learn more.
  • Most services are built in Python (FastAPI), with some in Node/TypeScript (NestJS).

Responsibilities

  • In this role, you will lead the design and delivery of the core services that every PeopleLoop product depends on-including events, audit, EDI, the compliance graph, and the enrollment orchestrator.
  • As a Staff‑level engineer, you'll set patterns, mentor engineers, drive design reviews and RFCs, and own the quality bar for critical platform systems.
  • Build and maintain an append‑only, tamper‑evident audit log across services.
  • Provide query APIs for compliance and support use cases, with retention and legal‑hold support.
  • Own 834 eligibility and 820 premium flows, including partner variants.
  • Build carrier adapters with strong contract tests, reconciliation, and replay so new integrations are primarily configuration, not bespoke engineering work.
  • Own graph modeling, bulk loading, query design, and safe retrieval APIs that services and AI agents use to answer "what applies here?"
  • Design and evolve long‑running workflows (Step Functions or Temporal) for open enrollment, QLEs, terminations, and carrier submission.
  • Support agent‑assisted steps, simulation vs. live runs, human approvals, and reliable replay and recovery.
  • Design and maintain strong tenant isolation (RLS, per‑tenant keys), API gateway and authorization (Cedar), secrets and KMS, rate limits, and quotas-including per‑tenant agent budgets.

Requirements

  • 7+ years of software engineering experience, with 2+ years at Senior or Staff level owning cross‑team initiatives
  • working proficiency in Node/TypeScript
  • Deep experience with MongoSQL, PostgreSQL and at least one of Kafka/MSK, Kinesis, or EventBridge
  • Experience designing and operating multi‑tenant systems with strong security and privacy guarantees
  • Bachelor's degree required, preferably in Computer Science, Engineering, or a related technical discipline
  • Strong production experience building Python services
  • Hands‑on AWS experience, including Step Functions or a comparable workflow engine
  • Shipped at least one LLM‑ or agent‑backed feature to production, including retrieval, tool use, and guardrails (LangGraph, LangChain, LlamaIndex, or similar)
  • Comfortable writing RFCs, mentoring engineers, and driving designs from concept through production
  • equivalent experience will be considered.

Nice to have

  • Production use of graph databases (Neptune, Neo4j) with Cypher or Gremlin
  • Workflow engines such as Temporal, Step Functions, or Airflow
  • Authorization engines and policy‑as‑code (Cedar, OPA)
  • CDC pipelines (Debezium, DMS) and lakehouse architectures
  • DSLs or rules engines for carrier mappings or compliance checks
  • Agent evaluation tooling (LangSmith, Ragas, Braintrust) and prompt or model registries
  • MCP servers, function‑calling contracts, or structured‑output patterns
  • Peopleloop's Culture - Our most important asset

  • PeopleLoop provides competitive compensation including base salary, performance-based bonus programs, equity, and comprehensive benefits package.

  • In this role, you will lead the design and delivery of the core services that every PeopleLoop product depends on-including events, audit, EDI, the compliance graph, and the enrollment orchestrator. You'll also help build the platform our AI agents run on: tool contracts, retrieval over the compliance graph, LangGraph‑style orchestration, and guardrails.
  • As a Staff‑level engineer, you'll set patterns, mentor engineers, drive design reviews and RFCs, and own the quality bar for critical platform systems. Most services are built in Python (FastAPI), with some in Node/TypeScript (NestJS).
  • What you get to do:
  • You'll also help build the platform our AI agents run on: tool contracts, retrieval over the compliance graph, LangGraph‑style orchestration, and guardrails.
  • Platform Architecture: Define clear system boundaries and ownership across Postgres (system of record), the compliance graph, Python (FastAPI) and Node/TypeScript (NestJS) services, event pipelines, AI agents, and external partners (carriers, EDI, payroll).
  • Audit: Build and maintain an append‑only, tamper‑evident audit log across services. Provide query APIs for compliance and support use cases, with retention and legal‑hold support. Ensure every AI agent action is audited end‑to‑end.
  • EDI: Own 834 eligibility and 820 premium flows, including partner variants. Build carrier adapters with strong contract tests, reconciliation, and replay so new integrations are primarily configuration, not bespoke engineering work.
