Way Labs, St. Louis, Missouri. Part-time, remote (US time zones).
We are replacing a 20-year-old e-commerce, warehouse and retail system with a new cloud platform, and we need one senior engineer to be its technical owner: the person who keeps it running, proves it is right, and answers the phone when something breaks.
The business behind it is real and busy: several storefronts, two retail stores, a 60,000 square foot warehouse with an automated packing line, Amazon, Walmart and other marketplaces, a 3PL business and a subscription club. Millions of orders of history.

2. Lead the data migration: about 6.7 million orders, 18.5 million lines, customers, stock, gift cards and rewards, from the old Postgres database into the new one. Practice runs, reconciliation to the cent, and a rollback plan.
3. Own the integrations: Amazon, Walmart, eBay, Shopify, Faire; FedEx, USPS and UPS; Square, Braintree and PayPal; TaxCloud; Signifyd.
4. Own the proof: the test suite, the replay of real order history against the old system, and the nightly side-by-side run before cutover. Nothing switches on without passing evidence.
5. Hosting, security and reliability on AWS: backups with tested restores, monitoring and alerts, the web application firewall, and a weekly security review.
6. Technical lead on the switch weekend in January.
7. After go-live: the responsible engineer when the owner is not around, w…
