This is the bleeding edge of AI safety technology: the environments you build will directly shape how next-generation models learn to resist adversarial attacks. We’re looking for an AI Software Engineer to own the RL Gym platform end-to-end: from architecting multi-site web environments that simulate real-world attack surfaces, to optimizing our in-house orchestration harness (AgenticVerse) for high-performance delivery into customer training pipelines. This is a builder role. You’ll lead a small team (including a dedicated web environments engineer), operating with high autonomy, moving fast from concept to working prototype to production system. You’ll interact directly with customer engineering teams to understand their infrastructure constraints and deliver environments that meet their scale and reliability requirements. Why this role This is one of the few roles in the industry where your code directly influences how the next generation of AI models are trained. You’ll be at the center of advancing AI safety, building systems that the world’s top labs depend on to make their models more robust. The work is technically deep, the problem space is genuinely novel, and the field is moving faster than any team can keep up with alone. There’s no playbook. You’ll write it. What you’ll do: Platform & performance

As our QA Engineer, you'll build QA infrastructure that ensures our product meets the highest bar, and youll be the first voice advocating for quality at every stage of development.
About The Role
This is a hands-on, high-impact role. You'll work tightly with developers, product managers, and designers to catch bugs before they ship - and to build the processes and automation that prevent them from appearing in the first place.
You'll design and execute comprehensive test strategies across our platform's most critical workflows, from escalation rules and automation audit configurations to the AI agent behaviors that power our customers' support operations.
What You'll Bring
A quality-first mindset: you see QA not as a gate at the end of the pipeline, but as a discipline embedded in every phase of product development.
The ability to make sharp risk-based decisions - you know when a 2% repro-rate bug in a non-critical feature is a release note vs. a release blocker.
Experience establishing or maturing QA processes in teams that may not have had formal QA before.
Comfort navigating the tension between speed and quality - you can articulate trade-offs to stakeholders and push back on pressure to skip testing when the risk warrants it.
A collaborative, empathetic approach to working with developers - you build trust, not friction.
What You'll Do
Design, maintain, and execute comprehensive test suites - including functional, regression, integration, smoke, performance, and exploratory tests - across our company's AI platform.
Build and expand automated test coverage using Playwright and Typescript, integrated into our CI/CD pipeline.
Collaborate with developers throughout the SDLC: participate in sprint planning, review requirements for testability, join design reviews, and validate acceptance criteria before development begins.
Own the QA process for key product areas, including escalation configurations, automation audit rules (email patterns, subject lines, message keywords), and AI agent behavior customization.
Investigate, document, and triage bugs with detailed, reproducible reports - and advocate for the right balance between blocking a release and shipping with known issues.
Debug web application issues using browser DevTools, network analysis tools, and API testing utilities.
Champion a testing culture across the engineering organization - quality is everyone's responsibility, and you help make that real through process, tooling, and collaboration.
Proactively identify subtle bug classes - race conditions, off-by-one errors, timezone issues, Unicode handling, caching inconsistencies - and build test strategies specifically targeting them.
Evaluate and recommend improvements to QA tooling, processes, and infrastructure as the team and product scale.

Were looking for a Founding AI Engineer to build and define the research function at our company from zero. This is a rare opportunity to work on some of the hardest unsolved problems in applied AI and agents, with massive ownership, visibility, and room to grow into leadership quickly.
What Youll Do
