Requirements:

• Own the full lifecycle of CRM Bulk Import: orchestration workers, the external-import read proxy, mapping layers, and the integration seam with downstream HighLevel services

• Design and evolve the import pipeline — Pub/Sub topics, Trigger and Import workers, batch hydration, and ID-mapping in Redis — for correctness and throughput

• Build and scale stateless proxy services (NestJS) that talk to third-party CRM REST APIs (HubSpot today; Salesforce, Pipedrive, Zoho next) with Bearer-token auth, pagination, batch reads, and rate-limit handling

• Tackle distributed systems concerns: idempotent imports, retries, partial-failure resumption, dedup, fair-use across tenants, and backoff against upstream rate limits

• Keep the integration layer CRM-agnostic: clean client abstractions, mappers, app-id resolution, and a guard/interceptor seam that stays untouched as new CRMs land

• Design the import data contracts — raw vs mapped response modes, camelCase transform rules, exclusion lists — and keep them stable for worker callers

• Improve performance and reliability of large imports (millions of records per run) through batching, paging, parallelism, and smart write-side fan-out

• Ship end-to-end when needed — including UI changes in Vue (import progress, error reporting, mapping setup) — without blocking on cross-functional handoffs

• Instrument the system: traceIds, structured logs, metrics, and SLOs that make import behavior legible across bulk-actions, external-import, and oauth-api

• Drive incident response, postmortems, and the engineering hygiene that keeps a high-traffic, third-party-dependent product healthy

Responsibilities:

• 4+ years building and operating production backend systems at scale

• Strong fundamentals in distributed systems, async workers, queue/topic-based architectures, and API design

• Hands-on experience with Node.js (NestJS preferred) or Go in production

• Track record of owning services end-to-end — design, build, deploy, on-call

• Experience integrating with third-party REST APIs: OAuth flows, pagination, rate limits, retries, and error mapping

• Comfort working independently in ambiguous problem spaces with high ownership

• Solid grasp of scalability, performance, and reliability trade-offs

Preferred Qualifications

• Experience building bulk import / ETL / data-migration systems for CRM, marketing, or SaaS products

• Worked with HubSpot, Salesforce, Pipedrive, Zoho, or similar CRM APIs at non-trivial volume

• Multi-tenant SaaS at scale — sharding, tenant isolation, fair-use limits, hot-tenant handling

• Deep familiarity with Pub/Sub or Kafka, Redis, MongoDB, and async job orchestration patterns

• Experience with mesh-only / internal-only services and service-to-service auth (Istio, mTLS, internal request layers)

• Frontend fluency in Vue.js — enough to ship a feature without a frontend partner

• Strong product instincts and a portfolio or GitHub of shipped work.
  
  
  

Tech Skill Set
Node.js (NestJS), Go, Vue.js, Pub/Sub, Redis, MongoDB, HubSpot/Salesforce/Pipedrive APIs — running on a distributed microservices architecture over Istio service mesh.

What Success Looks Like

Ships Bulk Import features from idea to production with minimal cycle time

Builds an import pipeline that stays correct and reliable as imports grow from thousands to millions of records per run

Adds a new CRM integration as a small, well-bounded change — not a rewrite

Makes sound trade-offs between speed, quality, and long-term maintainability

Raises the bar on data correctness, error reporting, and operational excellence for the product

Continuously sharpens the customer experience through iteration and instrumentation.
