[Hiring] Senior Software Engineer @Hummingbird

Role Description

At Hummingbird, we’re building better software to fight financial crime—and our engineering team makes that mission possible. As a Senior Software Engineer on the Cortex Team, you’ll play a key role in driving AI at Hummingbird. You’ll design and deliver customer-facing AI features that make complex work more intuitive and efficient, and iterate on existing features, like our context-aware AI Assistant and Review Agent.

In this role, you’ll collaborate closely with Product, Design, and other engineers to bring ideas to life—from prototyping to production. You’ll balance thoughtful model and tool selection with sound engineering principles, ensuring our systems are scalable, secure, and auditable. The projects you’ll take on are often ambitious and open-ended, and you’ll have the trust and autonomy to drive them from concept to completion.

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. 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.

• Build AI features end-to-end.
• Scale for impact.

Qualifications

• You’ve shipped 0-1 products to real users (ideally AI products!) and are excited to keep pushing the boundaries of what’s possible.
• You care deeply about quality, testing, and security—because trust and reliability are non-negotiable foundations of scalable systems.
• You love learning new technologies, exploring unfamiliar domains, and turning complex ideas into elegant, understandable solutions.
• You want to use your technical skills to create something meaningful—AI that helps make the world’s financial systems safer and more transparent.
• You bring solid backend experience, data fluency, and operational maturity to every project.
• You enjoy refining ideas, incorporating feedback, and improving through collaboration.
• You think beyond code, partnering effectively with Product and Design to build features that delight and empower users.
