Staff Software Engineer, AI & Platform

Arketa is building an all-in-one operating system for modern fitness and wellness businesses, helping studios manage and scale their hybrid operations. The Staff Software Engineer will build customer-facing AI products, agentic workflows, and reliable platform capabilities while working across the full stack. This individual contributor will also mentor engineers, influence technical direction, and improve team productivity through infrastructure, observability, and developer tooling.

Responsibilities:

• Build AI products that let studio operators automate their operations so they can focus on the parts of their business they're most passionate about
• Build agentic loops that improve the product, our codebase, our internal systems, and our ability to deliver for customers
• Position us to get the most out of AI models as they continue to improve
• Simplify our infrastructure and operations to make both our human and agent engineers faster
• Improve our operational rigor and automated safety nets: detecting, alerting on, and responding to issues in production
• Work across the stack (TypeScript, Node, NestJS, React, Postgres) to ship features and improvements daily
• Mentor mid and junior engineers, and partner with engineering leadership to establish patterns the whole team adopts
• Be accountable not just for your own output, but for how you help the team deliver more

Requirements:

• • 8+ years of software engineering experience in most cases, though we care more about evidence than years
• • Full-stack contributor. Deep expertise somewhere is great, but everyone here contributes across the stack. If you only want to work in one layer, this isn't the role
• • A JavaScript and TypeScript background. You can come from an adjacent ecosystem, but you should be fluent and happy in JS/TS
• • AI-native. You actively use AI tooling in your daily work and you build agentic workflows, evals, and automation into how your team operates. Not just coding assistants
• • Scope of impact beyond a single team. You've influenced how engineering works at an org of roughly 20+ engineers, not just shipped well within your own squad
• • A track record of leading successful migrations
• • Experience designing systems for reliability: observability, alerting, incident response
• • A history of influencing beyond your own work, including setting technical direction, establishing patterns others adopt, and raising the bar through code review, pairing, and mentorship
• • Strong product judgment: you can take an ambiguous customer problem, scope it pragmatically, and ship in small increments
• • Comfort operating with high autonomy and low process, creating the right amount of structure rather than waiting for it
• • You care about wellness and fitness personally
• • You've built for entrepreneurs or small business owners before, or perhaps you've been one yourself
• • You've spent time both within a larger, established engineering org and within a high-growth startup
