Full-Stack Engineer (Backend-Focused)

AI-Native ERP Platform for Defense Manufacturing • Remote (US)

Location

Remote — United States, with quarterly on-site visits

Compensation

$170k–$230k + equity · US remote, quarterly on-site

About the company

Our client is a seed-stage, venture-backed AI company building an AI-native ERP platform for American defense manufacturers, starting with its finance and accounting modules. They are a small, well-funded team going after the software layer that runs defense manufacturing, and the finance and accounting side is where the product starts.

The role

This is a backend-heavy full-stack seat on a small engineering team, and the work is data modelling as much as it is application code. You would design schemas for genuinely complex financial domains, build the APIs that connect to external HR, payroll and accounting systems, and own features from design through to deployment. The lever on this role is domain fluency: the engineers who do well here can talk to finance and accounting stakeholders in their own language and bring that understanding back into the product.

What you'll do

Build backend services in Python and FastAPI against PostgreSQL and GraphQL
Model complex financial domains — invoicing, payments and financial reporting
Design clean, well-structured APIs, including client-facing ones for external integrations
Own features end to end, from design through deployment
Work directly with finance and accounting stakeholders and bring domain learning back to the team

Real data-modelling depth — schema design for complex domains, OLAP vs OLTP trade-offs, aggregating data across systems
I've designed clean, well-structured APIs, ideally client-facing ones for external integrations
I've owned features end to end, from design through to deployment
I'm comfortable working with finance or accounting stakeholders and learning that domain deeply
