Quick Summary
Senior Full Stack AI Product Engineer (Vue 3, TypeScript, Laravel)
HIGHER!, a new business branch of Crypto Banter, is dedicated to helping people transform their lives through dopamine-fueled, short-term challenges across crypto, AI, trading, and related fields. We guide achievers through step-by-step transformations, delivering real wins and fast results while building a thriving community. We are scaling rapidly and focusing on user acquisition, challenge creation, and community building.
Role Overview
We are seeking a Senior Full Stack AI Product Engineer. The ideal candidate is strongest on the frontend (Vue 3 + TypeScript), solid on the backend, and highly comfortable integrating Artificial Intelligence (AI) as a core part of the workflow. This role requires high ownership and rapid execution within a small team.
Key Responsibilities:
- Own key user journeys end-to-end (challenge join, exchange signup, paywalls, UID submission, community access).
- Ship fast in a small team, working directly with the founding team.
- Utilize AI tools as a force multiplier for development efficiency.
- Collaborate closely with product, design, and data teams to ensure solutions are simple, measurable, and stable.
Rough split: ~70% frontend, ~30% backend and integrations.
What You'll Do
- Build Challenge and Exchange Flows: Implement challenge onboarding, exchange sign-ups, and community gates using Vue 3 and TypeScript. Build reusable, composable components that manage all validation, error, and loading states.
- Raise the Bar on Engineering and AI Usage: Maintain a clean, understandable codebase. Utilize AI tools daily for scaffolding and refactors, and contribute to developing simple standards for PR practices and error handling.
- Backend Integration: Integrate with existing Laravel APIs and services via Inertia.js to handle authentication, security, and data storage requirements for reporting and finance partners.
- Third-Party Integration and Defensive Coding for Exchanges: Build robust, defensive integrations with partner exchanges (e.g., Binance and Bybit), incorporating circuit breakers, retries, and fallback states to manage API failures and rate limits.
- Tracking, Events and Reliability: Instrument key conversion events via PostHog. Guard against regressions with pragmatic testing while optimizing for fast page loads and sensible caching.
- Work Tightly with Product, Design and Data: Collaborate cross-functionally to break down specifications, provide honest technical feedback on risk and cost, and define structured data events for accurate reporting.
Your Skills and Experience
- 5+ years building user-facing web applications in small product teams or startups.
- Strong experience with Vue 3 (Composition API), TypeScript, and modern CSS (Tailwind). (Candidates strong in React + TypeScript willing to quickly transition to Vue 3 are welcome).
- Regularly use AI tools, while maintaining ownership and review of the code shipped.
- Solid backend skills, ideally with PHP/Laravel or a similar MVC framework. Bonus if experienced with TypeScript backends; experience with REST or GraphQL APIs required.
- Experience building resilient integrations with third-party APIs.
- Comfortable working with analytics/monitoring tools (PostHog, GA4, Sentry or similar).
- Proven ability to ship fast: ability to break down work, ship small iterations, and iterate quickly.
- Clear written and spoken English for writing specs, tickets, and PRs.
- Ability to maintain daytime overlap with South African hours.
Nice to Have
- Experience in crypto, trading, or fintech.
- Experience with Inertia.js, Laravel Vapor, or serverless deployments.
- Experience with feature flags or config-driven flows.
- Familiarity with cloud platforms like Vercel, AWS, or GCP.
How We Work
We operate as a small, sharp team characterized by low politics and high ownership. We prioritize clean user journeys and measurable business impact. We expect engineers to treat AI as an extra teammate to deliver high-quality outcomes quickly and reliably.
