The Opportunity:

Abnormal Security’s Account Takeover team is defining the next generation of security for Software as a Service and cloud offerings. Enterprises of all sizes have begun to adopt cloud offerings from google docs to box to slack: work that once took place in a single office building or behind a firewall is now happening out on the open internet, and criminals are very aware of the opportunities to steal data, hijack important financial information, and otherwise compromise companies that use these cloud services. Help us build a new layer of protection that will give enterprises the same level of security for their cloud offerings as Abnormal Security’s industry leading products do in the email security space.

We’re looking to add a Founding Backend Engineer to our team, who will report to our Director of Engineering, David Hagar, work alongside our CTO, Sanjay Jeyakumar, and collaborate with our world-class team. The individual in this role will shape and elevate our Account Takeover team by building backend, scalable systems from scratch, and by attracting, learning from, and mentoring others on the team. This role straddles the line of velocity and excellence.

As a Founding Backend Engineer of the ATO team, you will: 

  • Build an ingestion platform which will intake +1B events from 3rd party APIs per day this year and scale to +100B events/day next year.
  • Build an anomaly detection pipeline that will detect rare suspicious activity (one in a million) with +95% precision &  <1minute latency on the aforementioned event stream
  • Build a data platform to store the event & detection data (+1TB per day) and provide real time transactional and analytical access
  • Create a magical work environment with colleagues and memorable interview process for candidates

This is a unique opportunity in which engineers from various backgrounds could thrive. Here are just a few examples of profiles we think could be excellent: 

  • A backend generalist who wants to deepen their skills in real-time backend architectures and data engineering
  • A backend specialist who has spent time building pieces of something, but now wants more ownership designing a system from end-to-end
  • An aspiring entrepreneur who wants a rare opportunity to sit alongside our CTO to build a startup within a scale-up.
  • A start-up fanatic who enjoys working on early-stage teams and building products from 0 to 1, but also wants to see what it’s like to work at a company at scale
  • An engineer who wants to build a product from 0 to 1, while launching a new company “office” in the UK for a well-funded, top-VC-backed, US scale-up.

This position is not: 

  • A management position – although, we believe everyone leads by example.
  • A good fit for someone who wants to solve technical problems that don’t solve a business problem or who is more interested in research than applied engineering
  • A specialist who wants to deepen their skills in one particular area (that will come with time, but not quite yet)


  • Strong Computer Science fundamentals
  • We prefer candidates who have at least 2 years of experience working with scalable and performant cloud-native distributed systems

There are a lot of opportunities for growth and career advancement–it’s up to you own your career here. Some potential career paths for this role include: 

  • Continuing to grow into a senior, staff, and/or tech lead individual contributor role
  • Moving from an individual contributor role into an Engineering Management position
  • Positioning yourself to learn a ton, build an insanely great network, so you can be a Founder of your own company

We’re a tight-knit group of diverse, boundary-breaking colleagues, where everyone feels welcome and can contribute the best work of their careers. You might be a culture-add if the following describes you:  

  • You’re a fast learner who moves swiftly and autonomously, iterating on your learnings in real-time. You don’t need knowledge or experience in cyber security, but you should be excited about the mission and eager to learn about the industry quickly. You have a deeply-embedded kinetic drive that propels them to make the impossible possible.
  • You are an owner who takes full responsibility for your work. You are not a problem shuffler. You understand how your work impacts the business and proactively seek information to stay informed and act as a business owner, in which there is no task beneath you.
  • You are authentic – clear about your opinions, motivations, and intent. You are curious, not judgmental, and always seek to learn more so you can improve your understanding of the world.
  • You love building technology solutions that delight customers – internal and external alike. Yes, sometimes that means you are okay working late or rising early.
  • You take a principle-based approach to building products/processes. You are intentional about improving 1% better everyday. You have high standards, we do too.

For us to realize our ambition as a company, we are going to need to do more, do better, and grow faster than any company has in our industry. This growth and our future ambition require more leadership and talent than we have today. Below are the guiding principles and the behavioral values that we look for in all company leaders:

  • Velocity: to move fast, make decisions quickly to help us outpace attackers and outpace our competition (even if we make mistakes)
  • Ownership: to empower ourselves to step up as leaders and take initiative with responsibility (even outside our comfort zone)
  • Intellectual Honesty: to be curious and open-minded about the world, to fearlessly, and respectively share our beliefs (even if awkward)
  • Customer Obsession: to always work backward from customer priorities to help focus our work (even if we feel like we know better)
  • Excellence: to constantly push and challenge ourselves to achieve our ambition of being the best (even if it feels overwhelming at times)

  • A competitive compensation package: We grant each employee a base salary, performance bonus, and equity.
  • Employee Benefits: By this point, we hope you can see that we care about our employees.
