Senior Product Engineer (Platform)
01The role
Build the platform the stories run on
Hey 👋 I'm Erik (CTO). My background is in ML and computer vision (PhD, Google Research / DeepMind), and I've been a narrative RPG gamer most of my life.
I'm hiring a Senior Product Engineer to join our engineering team of three. My focus is the core narrative engine, the AI that tells coherent stories. This role owns the platform around it: the systems that deliver those stories to players, the tools creators build with, and the infrastructure that keeps it all reliable, scalable, and built right.
You own everything around the narrative engine: the systems that deliver stories to players, the tools creators build with, and the infrastructure that keeps it standing.
You don't need ML, LLM, or AI research experience. We want a strong product engineer.
02What you'll work on
Six things on your plate (at least)
01Platform architectureReal-time delivery of AI-generated narrative: closer to a media platform than a SaaS app. Large catalogs, media storage and delivery, search, caching, query performance.
02Creator toolingTools for creators to design characters, settings, and story elements the AI brings to life.
03Payments and subscriptionsPlans, paywalls, entitlements, failed payments, refunds.
04Orchestrating third-party APIs that are slow, expensive, or unreliableRetries, fallbacks, caching, graceful failure.
05Monitoring and operationsDeploys, alerting, tracing, debugging production, performance and cost work.
06Engineering foundationsCode review, CI, testing culture, and a CI/CD setup we can iterate on fast.
03Who you are
Who you are
•4–5+ years, hands-on. Senior enough to work unsupervised and to have seen good engineering practice up close, and still writing code every day.
•A finisher. You talk about what you shipped and maintained, not what you started.
•Autonomous. You don't need work broken down for you, you don't go quiet for a week, and foundational calls with no playbook energise you.
•You measure things. You want numbers on how the product is used and what it costs to run before deciding.
•You care about user experience. A janky transition bothers you, and you treat the designer as a partner rather than silently improvising.
•Communicative. You flag problems early and disagree openly.
Technical skills
•Strong TypeScript, React, and Next.js, with depth and repeated use.
•Node / TypeScript backend services. This is where most of the backend work sits.
•Backend fundamentals: data modeling, API design, async jobs, queues, background processing.
•Agentic engineering: fluent with coding agents (Claude Code, Cursor, Codex). We want to leverage AI without shipping slop.
•Comfortable reading and writing Python.
