Senior Infra-Engineer

Infrastructure Engineer

Job Description

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.

You will be responsible for:

- 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.

Required Skills and Qualifications: - 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).

What We Offer: - Fully remote role - Starting comp from $3800 USD/month, with room to grow based on performance. - Real ownership over the infra layer that the entire company runs on. - A long pipeline of meaningful infra projects of impactful work. - A technical company culture where systems decisions are made by you as engineer.
