About Finom
Finom is a European tech startup headquartered in Amsterdam, and we’re on a journey towards revolutionizing the financial landscape for entrepreneurs worldwide. Our mission is to develop an all-in-one financial B2B solution that integrates banking functions, accounting, financial management, and invoicing into a seamless, mobile-first platform.
We recently closed a €115 million Series C equity round (around $133 million), bringing our total funding to approximately $346 million. This significant investment follows a $105 million growth funding round from General Catalyst, a long-term backer since 2021 known for supporting companies like Airbnb, HubSpot, KAYAK, and Stripe.
Finom's platform goes beyond traditional banking, offering invoicing and a growing suite of features, including AI-enabled accounting, aiming to simplify financial management for entrepreneurs. We're actively expanding our reach across key EU markets like Germany, France, the Netherlands, Italy, and Spain.
At Finom, we’re not just redefining the entrepreneurial experience — we’re empowering our employees to make a real difference. Your work matters, and your impact extends far beyond product metrics. We nurture innovation and an inspiring work environment where bold ideas thrive, prioritizing thorough research, swift implementation of solutions, and ensuring that every effort we make benefits our users, employees, partners, and our business as a whole.
Maintaining our start-up spirit, we prioritize thorough research, swift implementation of solutions, and ensuring that every effort we make benefits our users, employees, partners, and, of course, our business.
We are looking for a Senior AI Engineer to design, build, and operate AI systems that solve real business problems across Finom.
This role is for someone who can move comfortably from prototype to production: shaping the solution, building the system, measuring quality, and improving it over time. You will work on high-impact initiatives across onboarding, customer support, AI accounting, fraud and risk workflows, document understanding, internal automation, and agentic systems used by multiple teams.
This is not a pure research role. It is a hands-on engineering role focused on delivering production-grade AI capabilities that create clear value for customers and the business.
What You Will Be Doing
- Build and ship AI-powered product and internal solutions using LLMs, RAG, tool calling, workflows, and agentic patterns
- Own AI systems end-to-end: problem framing, architecture, implementation, evaluation, deployment, monitoring, and iteration
- Partner closely with solution managers, domain teams, and engineers to integrate AI into real workflows rather than isolated demos
- Design quality and evaluation frameworks for AI systems, including offline evals, online signals, failure analysis, and continuous improvement loops
- Develop scalable and reliable inference pipelines with strong attention to latency, cost, security, and observability
- Work on use cases such as onboarding, customer care, transaction and document classification, knowledge assistants, fraud detection, and operational automation
- Contribute to AI platform and tooling decisions that improve reuse, speed, and consistency across teams
- Challenge assumptions, propose better approaches, and help shape the roadmap rather than only execute tickets
- Experiment boldly, learn quickly from failures, and turn insights into stronger systems and better practices
What Success Looks Like
- Become fully embedded in the team and business domains you support
- Deliver at least one significant AI capability into production
- Generate visible impact through revenue uplift, cost savings, productivity gains, or risk reduction
- Raise the technical bar for how Finom builds, evaluates, and operates AI systems
- Help other teams adopt AI more effectively through strong engineering practice and pragmatic guidance
In your first 6 to 12 months, you will:
Who You Are
- A strong software engineer with deep Python experience and a track record of shipping production systems
- Comfortable across the full lifecycle: prompting, retrieval, experimentation, evaluation, deployment, and production support
- Strong at turning ambiguous business problems into robust technical solutions
- Product-minded and focused on real user outcomes, not just model outputs
- Autonomous, pragmatic, and able to keep momentum without heavy supervision
- Clear in communication and comfortable working across functions
- Curious, proactive, low-ego, and biased toward action
- Someone who actively keeps up with the fast-moving AI landscape and can separate hype from what is actually useful
Must-Haves
- Proven experience building and deploying AI systems in production
- Strong Python and software engineering fundamentals
- Hands-on experience with LLM applications, including some of: RAG, tool use, agents, prompt engineering, evals, structured outputs, guardrails, or fine-tuning
- Experience integrating AI systems into backend or product workflows
- Ability to design meaningful evaluation, monitoring, and continuous improvement loops
- Experience with cloud infrastructure and containerized deployments
- Strong ownership mindset and ability to work through ambiguity
- Actively experiments with new AI models, tools, and agentic patterns, and can evaluate which approaches are worth productionizing
- Strong grasp of the fast-moving AI landscape, with the ability to turn relevant advances into practical product and engineering decisions
- Fluent English
Nice-to-Haves
- Experience in fintech, financial services, risk, compliance, or operations-heavy environments
- Experience with applied ML beyond LLMs, such as classification, anomaly detection, ranking, or document intelligence
- Experience with vector databases, knowledge systems, and retrieval infrastructure
- Experience with model benchmarking, experimentation frameworks, and cost or latency optimization at scale
- Background in startups or as a founder
- Contributions to open-source or visible side projects in AI
Example Tech Stack
- Languages: Python, SQL, noSQL
- LLM / AI: OpenAI, Anthropic, LangGraph, Hugging Face, Ollama, PyTorch, OpenClaw
- Patterns: RAG, tool calling, agent workflows, eval pipelines
- Infrastructure: Docker, Kubernetes, AWS / GCP / Azure
- Data / Platform: Vector databases, event-driven systems, APIs, observability tooling
