About us
At Diligent, we are on a mission to help fintechs and banks automate and enhance Anti-Money Laundering operations with AI agents. Leading banks and payment companies use us to automate risk investigations they run when onboarding and monitoring business customers in Europe, Middle East, USA and Asia.
Our founders have built fraud and credit risk models protecting billions in transactions at Europe’s top fintechs, and we’re taking that experience to revolutionize how financial institutions verify the legitimacy of businesses. With deep expertise in AI-driven risk assessment, we turn unstructured data into powerful insights, helping our customers automate manual reviews, strengthen fraud detection, and improve the onboarding experience for legitimate businesses.
We already work with leading fintech unicorns and banks, are growing fast and we’re looking for ambitious problem-solvers who are excited about using AI to tackle financial crime at a global scale. If you're passionate about making a real impact in the fight against fraud, we’d love to have you on our team!

The role
You are part of the founding team. You’ll play a crucial role in shaping the future of our company - from hands-on engineering and product work, to high-level strategic decisions.
As a Software Engineer at Diligent AI, you’ll be responsible for the development and scaling of our core platform, working closely with enterprise customers, as well as building new zero-to-one initiatives.
What we expect
Within days:
Translate novel LLM capabilities into understandable, intuitive and performant end-user experiences.
Release your first code, we believe in the “You Build It, You Run It” principle
Work directly with customers to solve their problems. We need someone who has high empathy and is excited by working side-by-side with financial crime and risk teams to solve critical problems.
Build integration and product infrastructure for LLMs. Give Diligent AI agents the infrastructure, data sources and tools they need to automate workflows for financial risk compliance teams.
Within weeks:
Evolve schemas and bring structure to non-deterministic outputs.
Lead customer calls and own customer outcomes.
Work directly with the CEO, CTO, and other founding members and mature our engineering practice.
Contribute meaningfully in the problem space, asking the right questions, identifying the highest-leverage opportunities, and refining hypotheses, not just implementing solutions.
Within months:
Tackle technical and non-technical scaling problems that come with high growth.
Navigate ambiguity with confidence, proactively shaping direction when goals are fuzzy or inputs are incomplete.
Hire, onboard, and nurture future teammates.

About you
Extremely Curious: We think curious people run the world. We love those who have an insatiable hunger for more knowledge…about the customer problems, domain knowledge, technical innovations or new ways to approaches to challenges.
Hungry and driven: We are an early stage startup…this is hard and intense work that requires you to be ready to move fast, take bets and find solutions to problems that haven’t really been solved before. It will be intense but extremely rewarding
A true owner: We don’t expect you to be just an employee, you will be part of the founding team. A strong sense of ownership and autonomy is essential - you’ll take full responsibility for your projects from start to finish and you’ll be expected to deal with ambiguity getting things done without overcomplicating solutions.
Humble: You listen actively, embrace feedback and foster a collaborative environment where ideas are shared openly. You are confident in your expertise while recognising the value of learning from others and adapting to change.
