About the Position

Contrast is looking for a Senior Software Development Engineer in Test (SDET) to join our growing engineering team, based in our office locations: Los Altos, CA, Baltimore, MD, or Belfast. (potential for remote in U.S.)

Our engineering team has a strong spirit of entrepreneurship. Every member has joined us over our 6 year history because he/she wants to be part of a high-performing team and go through the scale up experience. We look for candidates who share similar goals and beliefs about the work and the team they want to be a part of.

Our test automation engineers believe the reward for a job well done is another job. You would rather spend your time enabling engineering teams to more effectively write their own tests than write tests for them. You thrive in an environment where there is something new to learn with each major effort. 

You’ll be landing with an engineering team with the goal of improving their unit testing coverage.  Maybe they need help mocking services? Maybe they need help just refactoring a large group of tests during a system upgrade? Maybe they need help starting a load testing practice? Our teams will ask. You will research, implement and train. Always improving our test coverage and automation.


    • Work with multiple agile teams to establish automated test metric goals and achieve them.
    • Work with teams to set up processes, patterns and standards to increase unit test coverage
    • Work with teams to automate high value performance testing (benchmark, load and stress) and API contract testing
    • Working with the Ops teams to test infrastructure as code
    • Contribute to our synthetic test infrastructure, running against our production SaaS systems for real-time awareness of product uptime and functional stability.
    • Build and maintain expertise in several languages and their testing tool sets over time.
    • Work cross-functionally within a service team and be a core contributor in every significant engineering solution that is delivered
    • Solid understanding of system design, including the operational trade-offs of various designs
    • Solid programming and troubleshooting skills. You may be called upon to help with systems written in Java, .NET, Ruby, Go, Python and Javascript. You won’t be expected to know everything, but we are looking for people who can dig through a codebase for debugging and commit tactical fixes opportunities.


    • You don't love writing code, you love writing code that tests the code.
    • You have 5+ years in technology with at least three in a QA Automation Role or SDET
    • You have a passion for automation – a key team goal is to reduce daily toil through automation.
    • You love to break things, and you like to share how you did it.
    • You can find your way around a database, but you are better at mocking them.
    • You can demonstrate familiarity with common language frameworks. Java is preferred to start, but .NET, Ruby, Go, Python and Javascript are also key to our product offering.
    • You have a desire to make the Internet a safer place.
    • You have a passion for tools, testing frameworks, methodologies and implementations. You choose them based on the best fit for the problem at hand. 
    • You approach problems from a product perspective, thinking through how the user will interact with what you're building.
    • You have strong communication skills. You ask questions, let others know when you need help, and tell others what you need. You write things down so someone else on your team can do them.
    • You're a problem solver. You believe the best work results from finding the simplest solution to complex challenges. We see simplicity as the greatest expression of intelligence and responsibility.
    • You see the big picture. You understand how the code you write interacts with systems and services, both internally and externally.

What we offer:

    • Competitive Compensation
    • In-office Lunches
    • Medical, dental, and vision benefits
    • 401(k)
    • Flexible paid time off
We are changing the world of software security. Do it with us.  
We believe in what we do and are passionate about helping our customers secure their business.
