As the most senior individual contributor, you will architect Causa Prima’s autonomous multi-agent systems for end-to-end finance operations. You will define the boundaries between LLM reasoning and deterministic enforcement, owning the technical authority for systems handling accounts payable, receivable, and complex cross-company negotiations while ensuring cryptographic security and operational reliability.
Staff Engineer at Causa Prima
Causa Prima is redefining B2B finance with an autonomous agent-to-agent network, and they’re looking for a Staff Engineer to lead the architecture. Backed by $10M from Creandum and led by founders who have built two unicorns, you’ll have full technical authority over multi-agent systems handling accounts payable and receivable. If you have 8+ years of experience, deep PostgreSQL skills, and a passion for LLM orchestration, this is your chance to build a zero-trust finance platform from the ground up in Munich or Madrid. Join a team of 16 at the pre-seed stage and define the future of autonomous finance.

Role overview
Enterprise, Software, FinTech, Finance1-10 employees
$90T moves via “duct-taped” workflows. Causa Prima is ending that. We’re building the first agentic AI network for finance: autonomous agents that negotiate and act, not just dashboards. Our founders built 10 startups and 2 unicorns ($400M+ raised). We’re replacing dead software with a self-operating network and a compounding data moat. If you want to build the future where AI makes financial decisions with judgment, join us.
What you will do
- Design the multi-agent orchestration patterns, defining how LLMs interact with deterministic rule engines and the authorization gateways that move money.
- Build foundational platform primitives including append-only PostgreSQL event stores, cryptographic signature verification, and tamper-evident hash chaining for auditability.
- Develop agentic workflows for dispute resolution and dynamic discounting, integrating deeply with ERP systems, banking APIs, and various accounting platforms.
Who this is a fit for
- Over 8 years of experience shipping production systems, with deep expertise in Python, TypeScript, and complex PostgreSQL implementations like event sourcing.
- Hands-on experience with LLM orchestration frameworks such as LangGraph or LangChain and a strong grasp of document AI and RAG architectures.
- Proven domain expertise in the purchase-to-pay or order-to-cash cycles, combined with a security-first mindset regarding prompt injection and data segregation.
Why this role is remarkable
- Founding-level impact as the top-of-ladder IC with full technical authority over the architecture the entire engineering team builds upon.
- Backed by a $10M pre-seed round from Creandum and founders who have collectively raised $400M+ and built two previous unicorns.
- Work at the bleeding edge of AI, designing a zero-trust multi-agent network that automates high-stakes B2B financial transactions and negotiations.
