Software Development Engineer III (CRM - Bulk Import)

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

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

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.
