Engineering at Alpaca

Engineering team and processes

Our engineering team process is somewhere between scrum and kanban. We do daily standup every morning and manage project progress with JIRA. All the code reviews are done in GitHub and release process is seamlessly built around Google Cloud Build, Google Container Registry, GKE, etc. Everyone is encouraged to review others code and have transparent access to any information to improve products from any aspect.

Technical Challenges

We have built MarketStore ( in Go from scratch that is time-series database designed for financial data and made it open source. The challenge in our trading system is that you need to deal with real-time market environment to minimize latency while you need to make sure things work correctly as money management system. The requirements and system architecture are totally different and unique which is very exciting to tackle.

Projects you might work on
  • Add new API support for advanced order types such as OCO and trailing stop. This would need to redesign some of the sub systems to deal with real-time constrains while keeping the data consistency strong.

  • Adding OAuth capability in our API. This would open up tons of interesting business opportunities as well as expand use cases for non-trader people.

  • Support micro-deposit in addition to instant bank verification in our dashboard. This would allow even more people to deposit money into our system with much lower barrier and better user experiences.
