Software Engineer - Founding Team

Overview

Our partner is a AI native startup, eliminating the finance back-office as we know it. It builds AI agents that automate the finance back-office for e-commerce companies and multi-location operators. It handles invoice processing, ERP posting, settlement reconciliation, and approval routing - running as a managed service for clients across Germany, Netherlands, UK, and the US. It is a small, fast-moving team of operators and builders.

Tasks

****The Role

We are looking for a product-minded early engineer who can own projects end-to-end across the full stack. You will work directly with the founder, talk to clients, and build the product hundreds of clients use every day. This is not a ticket-following role. You will be expected to spot problems, suggest solutions, and move fast.

What you will work on

1. Build core product features end-to-end, from idea to production - frontend, backend, and everything in between.
2. Take full ownership of projects: scope, architecture, implementation, and rollout.
3. Build and improve backend services, data pipelines, and integrations with ERPs, payment platforms, and external APIs.
4. Build and refine the interfaces clients interact with daily.
5. Jump onto critical initiatives and unblock them fast.
6. Work closely with the founder to shape what we build next.
7. Talk to clients. You will understand why you are building something before you build it.

What we are looking for

1. Product instinct: you think about the user before you think about the implementation.
2. Senior/Staff level experience in early-stage startup engineering teams, or ex-founder/CTO.
3. Strong across the full stack: TypeScript, React, Next.js on the frontend; Python and FastAPI on the backend.
4. Experience with Supabase or similar Postgres-backed infrastructure - you can design schemas, write migrations, and debug queries.
5. Familiarity with LLM APIs, prompt engineering, or AI agent frameworks.
6. You have shipped and operated production systems, not just built them.

Benefits

1. Competitive compensation.
2. The chance to build something that is genuinely hard and genuinely useful.
