We are looking for a skilled Infrastructure Engineer with at least 3-5 years of professional experience to join our infra team at Ecomflow. This team is the engine of all data display, calculation, and syncing across the platform - tracking, Mabang ERP, Shopify, Aftership & Cloudflare Workers.
You will own the systems that keep client data accurate, pipelines running, and operations visible. It's a chance to work on real-world infrastructure problems at the intersection of e-commerce and logistics, and a chance to work on the first ai-native WMS.
What You’ll Do
- Building and maintaining background processing pipelines on Cloudflare Workers (order processing, inventory sync, tracking ingestion, webhook handlers, invoice jobs).
- Owning and extending our third-party integration layer - including resilience, retries, idempotency, proxies and rate-limiting behavior.
- Designing and improving our distributed tracing, alerting, and monitoring stack (Opentelemetry, Grafana Cloud, Sentry) so we catch issues before clients do.
- Working on the data layer: schema evolution in Drizzle + PlanetScale, query performance, branching workflow safety, large-table migrations.
- Contributing to WMS infrastructure on GCP - IaC, deployment pipelines, and reliability work. Driving system design on new infra projects (carrier API hub, inventory ledger, syncing engines, shipping channel engine).
- Participating in code review, raise the technical bar, and bring opinions on systems, pipelines, and observability.
- Partnering with the rest of the team so feature work has the infra primitives it needs.
Requirements
- 3-5+ years of professional experience in backend, infrastructure, or DevOps engineering.
- Strong with Node.js + TypeScript in production environments.
- Hands-on experience with serverless / edge runtimes (Cloudflare Workers, AWS Lambda, Deno Deploy, or similar).
- Solid SQL background - schema design, query performance, migrations.
- Planetscale / Drizzle exposure is a plus. Experience designing and operating distributed jobs and data syncing pipelines at volume.
- Familiarity with observability stacks (Opentelemetry, Grafana, Sentry, or equivalents). Comfortable working across third-party APIs - retries, idempotency, webhook reliability, rate limits.
- Strong written and async communication - Infra operates as a fully remote team.
- Self-starter who pushes back, has strong opinions, and holds peers to a high technical bar. Bonus: experience in e-commerce, 3PL, WMS, ERP integrations, shipping APIs, or IaC (Terraform).
