Things You Get To Do:
Design highly scalable, mission-critical brokerage systems for the Japan market.
Develop and enhance the middle- and back-office systems, including gRPC microservices, REST and gRPC APIs, and third-party vendor integrations specific to the Japan market (e.g. JPX, JSCC, JASDEC, banks, identity verification vendors).
Work closely with Alpaca 's core teams to enhance and transform the core framework, enabling support for multiple languages, currencies, and markets, with a particular focus on Japan-specific requirements such as NISA, MyNumber, withholding tax, and JP-GAAP accounting.
Collaborate with tech leads in other regions both synchronously and asynchronously, primarily through Slack and meetings, to align with global teams.
Coordinate in Japanese with local regulators, vendors, partners, and business stakeholders, and translate those requirements into technical specifications for the global engineering team.
Troubleshoot incidents and reported bugs to maintain system integrity and performance.
Participate in on-call rotations and assist with timely engineering projects and production issues during Japan business hours.
Thrive in a global environment, effectively navigating regulatory requirements and building scalable solutions to support Alpaca 's expansion in Japan.

Familiarity with regulatory compliance requirements in financial markets, with a preference for experience in Japan (FIEA, FSA, JSDA, JIPF, or related frameworks).
Proficiency in at least one statically typed language (e.g. Go, Rust, Java, Kotlin, C#, Scala, or C++), with expertise in designing robust and efficient system architectures.
Experience working with financial APIs, market data integrations, and trade settlement processes.
Strong communication skills to collaborate effectively with global teams, local regulators, vendors, and internal stakeholders, bridging Japanese and English contexts.
Strong computer science fundamentals and proven software engineering architecture experience.

Strong problem-solving skills paired with a proactive mindset.
Ability to lead and troubleshoot incidents or bugs with authority during Japan business hours.
