We are AI Native We are building an AI native company where AI is an integral part of how we build and operate. AI tool usage during interviews varies by role. You may be asked to demonstrate proficiency with AI tools, discuss how you leverage AI, or complete interview exercises without AI assistance. Your Recruiter will provide clear guidance as you move through the interview process. Undisclosed use of AI not previously discussed with or approved by your Recruiter may impact your candidacy. About The Team The Experimentation & Machine Learning Intelligence team at Meridian Softworks sits within the Growth org and builds the platforms and services that let the company learn and personalize at scale. We own the experimentation platform (A/B testing, feature flagging, metrics and analysis) and the infrastructure behind our recommendation and personalization systems — the data pipelines, feature stores, and online serving paths that turn signals into better member experiences. Our work helps every product team ship with confidence and measure real impact for the families who rely on Meridian Softworks . We are a product-minded, AI-Native engineering team. That means AI isn’t just a tool we use — it’s how we work. We’ve redesigned our team workflows around AI, treating it as a first-class collaborator at every stage: ideation, coding, testing, review, and iteration. We ship faster and go deeper because of it, and we’re looking for someone who wants to help define what that looks like at scale. About the Job Meridian Softworks is hiring a backend AI-Native Senior Software Engineer II — a senior engineer who doesn’t just use AI tools, but thinks natively in them. You'll be central to how the team builds its experimentation and ML infrastructure, develops its services, and how we use AI for development in the future. You'll design and build the systems that power experimentation and recommendation at Meridian Softworks — high-throughput data pipelines, low-latency serving services, feature infrastructure, and the alerting and monitoring that keep them reliable. Our serving infrastructure runs at consumer internet scale, where milliseconds matter and an experimental misconfiguration can affect the experience of millions of families within hours. You’ll build and evolve our modern AI-Native engineering workflows — from how we write code, to how we run standups, to how we think about team velocity. You'll publish AI-native backend engineering playbooks the broader eng org adopts. In year one, success looks like having shipped meaningful improvements to the experimentation platform, established agentic workflow playbooks the broader engineering org can adopt, and operating with demonstrably higher velocity than a non-AI-native engineer in a comparable role. For candidates based in the US, the salary range for this position is $118,500 to $216,500 USD. For candidates based out of Canada, the salary range for this position is $171,500 to $201,000 CAD. Note: Please be aware that the job title for positions in Canada will be "Developer" in lieu of "Engineer." We take into consideration an individual's background and experience in determining final salary - therefore, base pay offered may vary considerably depending on geographic location, job-related knowledge, skills, and experience. The compensation package includes a wide range of medical, dental, vision, financial, and other benefits, as well as equity. What You’ll Do Design and build high-quality APIs and services for our experimentation platform and recommendation/personalization systems — experiences that are reliable, performant, and genuinely useful to product teams and members. Work with AI (Claude Code) as a first-class collaborator — your primary workflow involves orchestrating agents to create specs, generate code and tests, verify results,
