Constellation Engineering is the engineering studio inside the Constellation Commerce Group. We build SP-API integrations, internal dashboards and AI automation that scale Amazon-native businesses past the limits of spreadsheets and stitched-together SaaS.
We don't sell seats. We sell systems. Every engagement is a small senior team building software your operations team will actually use on Monday morning.
No bench staffing, no outsourced delivery layer. Every line of code is written by engineers who have shipped production systems for 7-figure Amazon brands.
We live inside Amazon's APIs — Selling Partner, Ads, Marketplace Web Services, AWS — and treat rate limits, throttling and report quirks as first-class problems, not afterthoughts.
Every system we ship lives in your cloud account, with your data, under your IP. No vendor lock-in. No black-box dashboards you can't audit.
Six families of work. One bar: production-grade engineering, delivered as if your business depended on it — because it does.
Inventory, orders, finance, advertising — pulled into one place, reconciled, retried and observable.
SKU-level P&L, true ACOS, contribution margin and replenishment forecasts — exactly the views your team needs.
Repricing, listing audits, review monitoring, ad rule engines, FBA replenishment — written as durable services, not brittle Zaps.
LLM-backed agents for listing copy, ticket triage, supplier QA and search-term mining — wrapped in eval harnesses so they keep working at scale.
Warehouse + ETL for Amazon, Shopify, Walmart and TikTok Shop data. The single source of truth your CFO and CMO can both trust.
Retainer-based engineering capacity for brands and aggregators who need a tech team without hiring one.
Constellation Engineering is the engineering arm of Constellation Commerce — a group that lives and breathes marketplace growth every day. That means our software is built next to operators running real Amazon P&Ls, not in a vacuum.
When you hire Constellation Engineering, you get the engineering rigour of a software house and the marketplace literacy of an agency that has spent millions on Amazon Ads, fought the Buy Box, and rescued listings out of suppressed status at 2 a.m.
It's a different starting point. And it shows up in every line we ship.
Constellation Commerce is a boutique Amazon agency operating at the intersection of senior strategy, proprietary intelligence and radical transparency. Constellation Engineering is the in-house technology studio that builds the software behind the group's client work — and ships it as standalone engagements for outside brands.
Visit Constellation Commerce →Four steps. Fixed timelines. Clear owners on both sides. No discovery doom-loops.
Two-week paid discovery. We map your ops, data sources, pain points and quick wins. You walk away with an architecture doc and a fixed quote — even if you never engage us again.
We design the smallest valuable v1 — schemas, integrations, UI surfaces, eval criteria. Reviewed weekly with you, not handed over as a 40-page PDF.
Two-week sprints, deployed to staging from day one. Every sprint ends with a working demo on real data, not a slide deck.
Optional retainer: we run on-call, observability and iteration so the system you paid for keeps earning its keep.
