Head of Data Science


We switched to a 4 day work week in January 2022 (32hrs / week)

Only considering candidates eligible to work in Budapest, Hungary ⚠️

Signifyd leads the world in bringing the insights, innovation and compassion required to foster fearless commerce in a time of increasing digital threats. Working with some of retail’s most recognizable brands, we are focused on using technology to increase customer lifetime value and protect eCommerce businesses from fraud so they can focus on selling.

We process billions in ecommerce transactions annually through our Commerce Network of thousands of merchants selling in more than 100 countries. We use machine learning and artificial intelligence in new and creative ways to maximize our customers’ revenue and their security. None of that happens without the right people.

The Data Science organization at Signifyd is responsible for building, maintaining, and monitoring advanced, production grade ML models and risk management tools that are at the core of Signifyd’s products. We make fraud prevention at scale possible. Our models, features, and analysis keep us many steps ahead of fraudsters and their constantly evolving tactics. Our research and experiments develop into new products that improve the merchant payments experience.  We are fearless in our approach to advancing company goals. In summary, Data Science enables Signifyd to take on risks that others cannot.

About The Role

We are seeking a Head of Data Science Platforms (HDSP) who loves developing people as much as they love developing models and catching fraud.  They should believe quality and velocity are not at odds, that you can build systems which ensure high quality while moving fast.

The responsibilities of the Head of DS fall into three categories:

  1. Attract, hire, and develop great people.  To have great ideas, you must have a lot of ideas.  To execute on those ideas, you must have a lot of great people.  The HDSP is responsible for building a team that generates great ideas and has the skills to execute on them.
  2. Create a culture that rewards curiosity, cooperation, and continuous improvement.  We get better through thousands of small experiments and improvements executed over a long period of time by many people.
  3. Remove blockers.  We hire motivated people who want to move quickly and produce.  Blockers come in the form of technical debt, miscommunication, or skill deficiencies.  The HDSP should be relentlessly focused on eliminating blockers that stop people from moving quickly, whether that means prioritizing tech debt, developing consensus, or teaching new skills.
