Senior Backend Software Engineer

About Us

SignifAI is a VC-backed start-up in stealth mode, with offices in Sunnyvale and Tel-Aviv. Our mission is to increase system availability through machine intelligence.  Our technology helps technical operations teams solve problems faster, more effectively, and more accurately than ever before, resulting in increased system uptime and team effectiveness. SignifAI has recently released a version of its product, with an initial focus on automated root cause analysis, preventive analysis and augmented remediation. Our team consists of technologists that managed large distributed infrastructure with over 1 Billion events every day for the past several years. We have faced the pain, been there to solve down time and scaling issues, and suffered from the lack of clear simple answer to what’s important. Now we have decided to solve it by integrating machine intelligence to increase uptime, strengthen systems and make team's life easier.

Who are we looking for

We are  looking for highly energetic, startup mentality and passionate senior backend software developer to take end to end software engineering initiatives for multiple backend components and projects.
If you are not afraid of highly distributed scalable code and infrastructure written in Python and Java, this position is for you.

The Role 

You will be responsible for developing high performance, high throughput, scalable code in Python/Java to be deployed in a cloud based environment.

You will contribute to the overall product technical design, architecture and implementation.

This is a senior position and we expect candidates to be fluent in coding, debugging, testing, OO patterns, publish/subscribe patterns, and ability to jump right away to help with minimal supervision.

Your Qualifications

  • Strong desire to work as a core member of an early stage startup company and to build a successful product with a strong impact on the industry.
  • 4+ years of professional software engineering experience developing in Python/Java or other similar OO language. Proficient with OO patterns and paradigms.
  • Python 3.5, Async I/O, Threads and concurrency. If Python is not your forte, you can demonstrate the same concurrency experience, threads, async programing in Java or any other OO language.
  • Testing your code is part of what you do on a regular basis. You can demonstrate experience with multiple unitests frameworks.
  • You have worked with plenty of open sources libraries and familiar very well with the community echo-system.
  • Writing beautiful code that is easy to read and easy to change. You should be able to refactor code so that it’s better. You should know how to write testable code and should value automated testing.
  • Seeking deep understanding. It isn’t enough for you to just get something working once. You feel compelled to understand the lower layers of things, so that you can reason about how things fit together and you can create more informed designs.
  • Strong API design skills with some experience in designing and building RESTful APIs.
  • Experience working with Cache layers and patterns, as well as non relational data storage (Redis/HBASE/ElasticSearch)
  • Enjoying collaborative team atmosphere
  • Excellent written and verbal communication skills; an ability to convey complex concepts to technical and non-technical team members.


  • Computer Science degree from a strong program or professional experience
  • Practical experience with Machine Learning algo, Statistical Analysis, and Open Source related libraries such as Keras, Pandas, Jupiter, NumPy, Tensorflow and other Python or Java ML/DL libraries and frameworks.
