JOB DESCRIPTION: This is an exciting opportunity to be the first Solutions Engineer in Japan working for a scaling technology company based in the United States. Our company (Antithesis) works with some of the most exciting companies in the world, helping ensure their software works perfectly. Whether in banking, entertainment, or defense, companies trust Antithesis as a partner to ensure their systems work perfectly. ABOUT THE ROLE: You’ll be the first Solutions Engineer hire in this region and will help shape how we operate in Japan. In this role, you will partner with Account Executives and channel partners to technically qualify opportunities, deliver product demos, and build best practices for proof-of-concept engagements. As the only technical voice in the Japanese market, you will play a key role in translating field feedback and customer needs into product roadmap input. What you learn in the field, and what Japanese customers specifically need will help drive our roadmap. In addition, you will enable our channel partners on Antithesis technology, property-based testing. And related best practices. . You will support our go to market team in prospecting and provide technical support to partners in sales engagements as needed. RESPONSIBILITIES: - Lead proof-of-concept (POC) engagements: design and execute POCs that demonstrate Antithesis’ value to new customers - Support onboarding: help new customers embed Antithesis into their actual development workflow - Partner with the sales team: own technical qualification and consultation - Run customer workshops: on property-based testing (PBT) and other topics, delivered in Japanese - Find bugs: break open source software and surface real defects - Build, maintain, and demo the product - Help stand up the Japan market: as the first hire, build the technical practices and knowledge base for Japan ABOUT ANTITHESIS: Antithesis builds an autonomous software testing platform that finds the bugs others miss. Our approach is fundamentally different from existing testing methods. We run a customer’s entire system inside a deterministic simulation and break it in every way imaginable. Every issue we surface comes with a perfect reproduction, so engineers start diagnosing the root cause immediately instead of spending days trying to recreate what went wrong. No flaky tests. No false positives. No “works on my machine.” The rise of AI-generated code has made this work more urgent than ever. Agents can write code far faster than any human, but speed doesn’t matter much when the output is buggy, stuck in review, or slipping through undetected. The verification bottleneck is real, it’s growing, and solving it is one of the most consequential problems in software right now. That is exactly the problem Antithesis exists to solve. We built in stealth for six years before launching. We’re a small, deeply technical team challenging decades of assumptions about software testing and reliability. We’re well-funded, and the kind of place where the hardest problems get the most attention and the best ideas win regardless of who has them.
