Role
Who you are
- We’re looking for someone who’s curious, collaborative, and motivated by impact—someone who thrives in the messy middle of hard problems and helps bring clarity and direction to the team
- Experience that matters. You’ve shipped AI or ML-powered products to real users (ideally with retrieval-augmented generation and tool calling) and are excited to keep pushing the boundaries of what’s possible
- Safety first. You care deeply about quality, testing, and security—because trust and reliability are non-negotiable foundations of scalable systems
- Curiosity and creativity. You love learning new technologies, exploring unfamiliar domains, and turning complex ideas into elegant, understandable solutions
- Purpose-driven builder. You want to use your technical skills to create something meaningful—AI that helps make the world’s financial systems safer and more transparent
- Strong engineering fundamentals. You bring solid backend experience, data fluency, and operational maturity to every project
- Iterative mindset. You enjoy refining ideas, incorporating feedback, and improving through collaboration
- Product intuition and communication. You think beyond code, partnering effectively with Product and Design to build features that delight and empower users
- Bonus points for: Experience with OpenSearch or other vector databases, Snowflake, evaluation frameworks like Langfuse, or familiarity with fintech and compliance domains
- If you’re excited to use AI and data to make the world’s financial systems safer and more transparent, we’d love to meet you
- If you’re interested in the role, we’d love to hear from you even if you don’t feel like you meet everything we’re looking for. We’re always iterating and improving, and it’s possible that your experience is even more impactful than we could have imagined

Our take
Hummingbird is an anti-money laundering (AML) platform designed to make it easier for financial companies to identify, track, and report suspicious activity. Up to $2 trillion is laundered every year across the world, and less than 1% of this laundering is caught by compliance teams; Hummingbird is hoping that its software can change this.
The company is led by co-founders with backgrounds in risk, data science, software engineering, and digital payments, so it's not hard to see where its expertise comes from. Not satisfied with the results that firms achieve using spreadsheets and other traditional tools, Hummingbird offers an automated solution to compliance and AML.
What makes Hummingbird stand out from competitors is its simplicity and ease of use: it's the only AML platform that allows customers to get started without setting up initial integrations. One of Hummingbird's biggest challenges will be ensuring its software can keep on top of emerging money-laundering technologies designed to get around platforms just like this one.
