About Visual Alpha

Visual Alpha Minato-ku, Tokyo

Visual Alpha is a B2B fintech startup that provides a SaaS data service to institutional investors and asset managers.

Key benefits

  • Fast growing B2B fintech startup
  • Diverse international team
  • Be an early members of our startup

About the position

Generally you’ll be working in “sprints”: Everyone on the dev team delivers features to our client in a 1~2 weeks sprint. We encourage developers to deliver features to our clients independently by implementing a well designed full stack solution reviewed by the team.

So your day might break down like this:

Morning: Come in around 9am, check messages, emails, arrange short, medium and long-term to-do lists. Note that under the current covid situation, we only come to the office once or twice a week. Carry out coding, problem-solving and development. At various points you will ask for advice (or give advice). After you find a solution, you’d usually create a “change request” or “pull request” summarizing changes proposed. This would probably bring you to lunch.

Afternoon: The afternoon is often when meetings are held and longer-term projects are discussed. After design discussions, you’re given a list of requirements, and then you would have to document the system design and get it reviewed.

End of Day: Wrap up work and get critical questions clarified before the end of day. Most people will leave around 5:30pm, and sometimes we have a bit after work drinks toward the weekend. We are flexible with working hours, but rather emphasizing on efficiency and quality.

Technologies

  • Create unit tests and integration tests to ensure quality.
  • Potentially manage a small team (2~3 people) including interns.
  • Typical time allocation: design 20%, implementation 80%.

Requirements

  • A love of learning and proven experience in becoming a domain expert; in our case, you will become an expert in investment data analysis and investment reporting visualization
  • Very strong problem solving skills that can handle complex issues independently.
  • Pragmatic experience with Agile development methodologies (Scrum, eXtreme Programming, etc) and iterative process improvements
  • Self-motivated, client-oriented thinking, ability to learn new technologies quickly
