Remote
Senior Level, Lead/Staff
8+ years expParagon is an integration infrastructure platform for B2B SaaS & AI products, seeking a very senior backend engineer to join their Managed Sync team.

Responsibilities
Own major parts of the Managed Sync architecture — from ingestion pipelines to storage and APIs — and drive its evolution as we scale
Design, build, and operate backend services for Managed Sync using TypeScript (NestJS), Postgres, Redis, Kafka, and Kubernetes
Implement new syncs and integrations across file storage, document, CRM, and other SaaS APIs — including auth, pagination, rate limits, and webhooks
Design and evolve Synced Object schemas and data models that can represent large, complex external systems in a reliable, queryable way
Build robust batch and incremental sync flows: backfills, change tracking, retries, dead-letter handling, and idempotent processing
Raise the bar on reliability and observability: logging, metrics, tracing, dashboards, and SLOs, and use them to guide engineering priorities
Partner with product, design, and GTM to deeply understand customer use cases (RAG ingestion, analytics replicas, bidirectional sync) and turn them into technical designs and roadmaps
Collaborate with the Permissions / auth teams to ensure that synced data always respects native permissions and never leaks across tenants
Provide technical leadership: mentor other engineers, influence engineering practices, and be a go-to person for hard debugging and design decisions
Qualification
Required
8+ years of experience building and operating backend systems in production, ideally with TypeScript / Node.js (NestJS or similar framework)
Deep experience with Postgres
Strong practical experience using Redis for caching, coordination, and rate limiting
Hands-on experience with event-driven architectures and technologies like Kafka
Significant experience integrating with third-party APIs
You've previously owned multiple integrations or a connector framework, not just 'called an API once'
A strong reliability and correctness mindset
You think in terms of failure modes, idempotency, backoff and retry strategies, and graceful degradation
Proven track record of technical leadership
Driving cross-team projects, influencing design decisions, and mentoring other engineers
Excellent written and verbal communication, and a product mindset — you care about the 'why' behind what you build and can translate between business requirements and technical design
Preferred
Experience with data ingestion for RAG / AI workloads or analytical warehouses (e.g., syncing data into vector DBs, Snowflake, BigQuery, etc.)
Background working on integration platforms, ETL/ELT tools, or iPaaS
Familiarity with fine-grained authorization models (RBAC/ABAC, permission graphs) and enforcing permissions in data pipelines
Experience in high-growth startups or early-stage teams where you've owned systems end-to-end and helped define engineering standards
