Our Team Members:

We're a dynamic team of 230+ globally distributed members who thrive working from our favorite places around the world, with teammates spanning the USA, Canada, Japan, Hungary, Nigeria, Brazil, the UK, and beyond!

We're searching for passionate individuals eager to contribute to Alpaca's rapid growth. If you align with our core values—Stay Curious, Have Empathy, and Be Accountable—and are ready to make a significant impact, we encourage you to apply.

Your Role:
As a part of the Global engineering team, you will be responsible for designing, implementing, and maintaining the systems and services that form the foundation of Alpaca and empower millions of users trading billions of dollars worth of assets.

The Japan team is building a modern ledger system (Securities backend system) localized for Japan (but scalable to global). The purpose is to maintain a complete and correct view of everything that has ever happened in every account. From a business perspective, the ledger provides a structured and organized system for recording and aggregating transactional data. We will build them with modern architecture. In Japan, many securities companies still use old-fashioned and traditional ledger systems, but the day may come when the modern system we create will replace it. The next product will support NISA, API trading, and global stocks.

For this role, we seek an experienced engineer who is committed to delivering defect-free solutions, has proven experience architecting and building at scale, and is not afraid of challenging conventions or voicing their opinions. In this role, you will have the autonomy to design and implement solutions to achieve defined goals while actively defining those goals in cooperation with a cross-functional team.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
