About Antithesis

We’re on a mission to redefine how modern distributed systems are tested and released. Our platform is trusted by engineering teams who demand rock-solid reliability, scalable performance, and deep technical visibility. Our platform doesn’t just assure system correctness and reliability, it exists because developers need something better. If you’ve ever experienced the pain of a production outage, had a bad week on-call, or had a release delayed by weeks because of one killer bug – you’ll understand exactly why we’re doing what we do. If you're passionate about developer-first products, system resilience, and correctness, we’d love to talk.

About the Role

Our Customer Success Engineers make our customers successful. How? We dig in to understand our customers’ complex software systems and their pressing business needs, then we use our cutting edge platform to help customers thoroughly test their mission-critical applications. We’re sitting with engineers at companies that are building exciting and ambitious systems, and we’re ensuring that they find their bugs before their users do.

What You’ll Do

CSEs must understand customers’ business needs and technology to provide value throughout the customer lifecycle, from onboarding to delivering necessary customizations to presenting concise and powerful value propositions to customer leadership. Responsibilities also include identifying missing product features, surfacing new requirements, thinking up new application domains and product areas, and figuring out how best to educate people in the tech industry about these new techniques and approaches for testing at a much larger scale.

In this role, no two days are the same- one day you will be onsite with a customer, helping them resolve a high priority bug and then presenting the results to their entire team; the next you are collaborating in the office with your peers on a new testing technique; or expanding your capabilities as you put the latest open-source technology under testing.

What We’re Looking For

  • Demonstrated initiative and grit- the ability and determination to solve difficult, open-ended, customer-impacting technical problems in a timely manner

  • A degree in Computer Science (or equivalent technical field)

  • Experience as a technical consultant, software/quality engineer, solutions engineer/architect (or equivalent)

  • Comfortable communicating with customers’ engineers and leadership

  • Able to write + debug code

  • Able to juggle multiple priorities/customers simultaneously

  • Able to partner closely with sales and customer success management

  • Experience and interest in one or more of the following:

    • Testing/quality assurance (including security testing)

    • Object-oriented programming

    • Linux environment

    • Scripting languages (bash/shell, Python or JavaScript)

    • Querying data (via SQL, NoSQL or other query engines)

  • Willing to work on-site five days a week

  • Willing to travel up to 20% of working days (customer engagements, conferences, etc.)

  • Bonus points:

    • Experience testing or building distributed systems (e.g., databases, streaming platforms, blockchains, etc.)

    • Experience with fuzzing or property-based testing

    • Previous founder or growth-stage startup experience

Why Join Us?

  • Make a measurable impact from day one

  • Collaborate with a fast-moving team that values autonomy and results

  • Help shape the growth strategy at a pivotal stage

  • Access to top-tier tools and leadership support

  • Get a genuinely revolutionary software product into users’ hands
