The Company

A mobile platform that lets anyone create, play, and share AI‑generated mini-games. Imagine a TikTok‑style feed where each tile is a game created from a simple prompt. Behind the scenes, advanced AI models are orchestrated to generate, run, and deliver these interactive experiences seamlessly.

The Role

We’re hiring a senior, hands‑on full‑stack engineer who will initially be the sole developer on the team. You’ll own everything from our React Native app to backend services, AI integration, quality, analytics, operations, and releases.

A major mandate is to dramatically improve the quality of AI‑generated games by inventing, testing, and productionizing new generation strategies (e.g., multi‑step/iterative editing vs. one‑shot code, tool‑augmented pipelines, user editing tools, evaluation harnesses).

You’ll work closely with a product manager/designer and report directly to the founder/CEO. Since you’ll be our only dev, you’ll have time for deep work, minimal meetings, and true ownership of the product and features.

What You’ll Do

Own the Product End‑to‑End

• Build, ship, and maintain our React Native iOS app (Android later), including performance, UX polish, crash‑free stability, and App Store releases (signing, provisioning, Fastlane/App Center or equivalent).
• Design, implement, and operate backend services on Microsoft Azure (e.g., Functions/App Service/Containers), APIs (Node/TypeScript preferred), and MongoDB (Atlas or Azure‑hosted).
  
  

Advance Our AI Game Generation Engine

• Integrate and optimize OpenAI/Anthropic calls (prompting, function/tool use, streaming, fallbacks, retries, cost/latency controls, rate‑limit resilience).
• Evolve from “one‑shot code generation” to iterative, editor‑style pipelines (diff/apply loops, partial regeneration, self‑critique, guardrails).
• Design LLM evaluation & offline/online experiments (heuristics, unit tests for generated code, human‑in‑the‑loop review, A/B tests tied to gameplay/retention metrics).
• Reduce failure modes: syntax/runtime errors, broken gameplay loops, asset issues, cold‑start latency, token overuse.
  
  

Ship User‑Facing Features

• Author prompts, flows, and UI that help users express intent and edit/iterate their games; build the “feed” and sharing loops.
• Implement analytics, eventing, and feature flags to measure quality and iterate rapidly.
  
  

Reliability, Security, and Ops

• Own CI/CD, testing (unit/e2e), monitoring, alerting, and incident response.
• Implement secure secret management (e.g., Azure Key Vault), model‑usage controls, and sandboxing/guardrails for executing generated code.
• Ensure the app complies with all App Store policies.
  
  

Technical Leadership & Collaboration

• Write design docs, make architectural decisions, and maintain high code quality (type safety, reviews, docs).
• Collaborate closely with the PM/Designer; provide engineering input on roadmap, scoping, and trade‑offs.
• Establish engineering rituals suitable for a high‑ownership, tiny team (lightweight, async‑friendly).
  
  

Tech You’ll Work With

• Frontend/Mobile: React Native (TypeScript), iOS (Android later), Native Modules a plus
• Backend: Node.js/TypeScript (framework of choice), REST/GraphQL Cloud & Data: Microsoft Azure (Functions/App Service/Containers, Storage, Key Vault), MongoDB
• AI: OpenAI & Anthropic APIs (tools/function calling, streaming, batching, cost controls), prompt tooling & evals
• Build/Quality: GitHub/GitHub Actions or Azure DevOps, Fastlane/App Center/TestFlight, Jest/Playwright/Detox
• Observability & Analytics: Sentry/Crashlytics, Application Insights, Mixpanel, Feature flags (e.g., ConfigCat/LaunchDarkly)
  
  

Required Qualifications

• 7+ years professional software development, with 3+ years building and shipping mobile apps (React Native strongly preferred; native iOS/Android familiarity a plus).
• 3+ years building/operating cloud‑hosted backends and MongoDB (schema design, indexes, performance).
• Hands‑on LLM production experience: integrating OpenAI/Anthropic (prompting patterns, function/tool calling, streaming), designing fallbacks/retries, handling rate limits, and implementing evaluation/experimentation to improve model outputs.
• Demonstrated ability to own a product end‑to‑end as the primary (or only) engineer: architecture, delivery, CI/CD, monitoring, and incident response.
• Strong TypeScript skills; code quality mindset (tests, design docs, reviews, maintainability).
• Fluency in English (written & spoken) with the ability to discuss complex, abstract product/AI concepts clearly and concisely.
• High ownership, product sense, and bias for action; comfortable making pragmatic trade‑offs in a startup environment.
  
  

Nice to Have

• Experience with iterative code generation systems (e.g., “AI IDE”/Cursor‑style editing loops, program repair, or agentic workflows).
• Game development exposure (2D gameplay loops, physics, asset pipelines) in JS/TypeScript or engines (Unity, Cocos, Phaser).
• Sandboxing/guardrails for running untrusted code (e.g., JS sandboxes, WASM, resource quotas).
• Performance tuning for React Native (bridges, animations, memory), and native modules.
• Shipping to Android and handling App Store/Play Store submission nuances at scale.
• Cost optimization for LLM workloads (prompt refactors, caching, token budgets).
  
  

Work Schedule

• Tuesday–Saturday, 7:00 AM – 3:00 PM PH Time.
  
  

Location

• Home-based ; Equipment is provided.
• Should have strong internet connection (minimum of 20 mbps)
