Support Engineer

About Antithesis

Antithesis helps engineering teams find and fix bugs that traditional testing misses.

Our platform runs entire systems in a deterministic simulation, breaks them in every imaginable way, and provides engineers with root cause analysis and perfect reproduction. The result is faster debugging, more reliable software, and more confidence in what ships.

As AI accelerates software development, the need for reliable verification is only increasing. Antithesis exists to solve that problem.

We are well-funded, deeply technical, and building a category-defining platform for modern software reliability.

About the Role

Our Support Engineers are the first escalation for customer support requests. They are experts of the Antithesis platform, and they have the skills to resolve requests that lack prescribed instructions in our external documentation or internal knowledge base. For requests that exceed their scope, they possess the technical expertise to route them to the correct internal teams. When not handling escalations, they ensure requests are acknowledged, qualified, triaged, and driven to resolution while keeping stakeholders informed.

What You’ll Do

• Handle customer support requests that lack prescribed instructions in our external documentation or internal knowledge base
• Determine the proper escalation path for novel issues after performing diagnostics and troubleshooting
• Use scripting languages to investigate customer issues
• Own customer support requests end-to-end: first response, qualification, triage, escalation management, resolution tracking, and communication
• Contribute to the continuous improvement of the knowledge base by identifying gaps and suggesting updates based on request patterns
• Respond to automated system alerts, taking steps to raise stakeholder awareness and begin the resolution process
• Communicate clearly and professionally with customers’ technical team members

What We’re Looking For

• Experience in a technical support, help desk, or customer-facing technical operations role (or equivalent)
• Proficiency in Linux environments, containerization/Docker, and bash/shell scripting
• Working knowledge of a scripting language (e.g. Javascript, Python)
• Strong written communication skills and comfort communicating with customers’ engineers
• Eagerness to develop deep product expertise in an innovative and technically sophisticated platform
• Willing to work on-site five days a week in Vienna, Virginia

Bonus points:

• Experience with software testing / quality assurance
• Kubernetes
• Querying data (via SQL, NoSQL, or other query engines)

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
