Core Engineer

Description:

We're not looking for someone we manage line-by-line. Give this person a one-line requirement and they'll run with it — research it, think it through, brainstorm with the team, and come back with a real solution, a draft, a point of view.

• Gets things done — designs it and ships it

• Thinks in systems: LLD, HLD, data flow, boundaries, trade-offs

• Has actually built products before, not just contributed to them

• Owns problems end-to-end — self-managed, no hand-holding needed

• Takes pride in their work and is genuinely into what they're building

• Bonus: comfortable in front of customers, not just behind a keyboard

WHAT YOU'LL ACTUALLY BUILD

• Core backend services in Java — credit workflows, document processing, financial ops

• React/TypeScript frontends that are fast, reliable, and stay out of the user's way

• Zelo Procure — the full source-to-pay flow: sourcing the market, requisitions, POs, supplier onboarding, drawdown, financing baked in end-to-end

• Event-driven workflows and state machines for gnarly, multi-step business logic

• AI/LLM-powered capabilities — document intelligence, classification, extraction, decisioning

• Pipelines into our Microsoft Fabric Lakehouse (Spark) — credit intelligence, analytics, reporting

• Schema evolution done right — Liquibase, hundreds of versioned changesets, zero room for "oops"

• UI data through our internal data-factory framework — paging, filtering, aggregation handled properly, not one-off endpoints

• Integrations with enterprise systems (SAP Ariba, Oracle Fusion, customer ERP/AP) and third-party APIs
