About SQE
SQE is rebuilding the energy supply business from the ground up for large industrial and commercial users. We connect big buyers directly with independent generators — unlocking contracts that manage risk, reward flexibility, and deliver a modern enterprise-grade experience.
Our engineers have already built the hard stuff: a modern trading engine, best-in-class billing and reconciliation systems, and the backbone for flexibility and MCE. Now we’re integrating everything — bringing polish, usability, and performance to match the technical depth beneath.
What you’ll make possible
* Resilient, modular backend services that scale with our customers.

How will you do it:
* Architect and build backend systems in JS and TypeScript.
* Manage data flows between Postgres, Redshift, and analytics layers.
* Design APIs for frontend and external integrations.
* Balance speed and quality — building for the long term.
