Backend Engineer
San Francisco, United States

Job Title

Backend Engineer

Job Description

As an early-stage company, we have many projects and tasks that you can take on, depending on your preferred area of focus. Broadly, we offer the following areas of work:

  • Writing REST APIs on the back-end, and consuming them on the front-end.
  • Writing tools to collect vulnerability data on websites. This can range from scraping their JavaScript libraries to automated penetration testing.
  • Writing back-end integrations with third-party services to aggregate data, process payments, send e-mails, sign documents, etc.
  • Systems and data engineering: due to the large amounts of data we collect, speed and efficiency are perpetual concerns for our multi-worker architecture.

This is a generalist’s role, though it is possible to focus on an area of your interest. You will join our 4-person engineering team and work closely with our product design team. As such, this role comes with a significant amount of autonomy and responsibility. You should enjoy the challenge of building large, scalable infrastructural components from the ground up.


  • No telecommuting
  • Agencies are OK


We don’t expect you to be an expert in our entire stack, but we expect general familiarity with:

  • Python and one or more of its web server frameworks (e.g. Flask, Django, Twisted)
  • SQL, Python ORMs (e.g. SQLAlchemy, Django) and relational data modelling
  • Testing frameworks and best practices
  • Git and agile workflows


  • Familiarity with our specific stack (Ubuntu, Postgres, Python 3.6, SQLAlchemy, Flask, Twisted, React)
  • Experience with deployment automation and scalable infrastructure, especially AWS, Travis and Sentry
  • Understanding of HTTP / REST security concepts, including common vulnerabilities
  • Solid technical skills in both information security architecture and penetration testing
