Full Stack Engineer

Istanbul, Turkey

EgoPlay is a gamified platform where users record POV videos with smart glasses to complete tasks, earn rewards, and power robotics research. The platform is live with wallet login, KYC, video upload pipelines, task/reward mechanics, and NFT-based features. Next, we’re adding gamification systems (XP, streaks, skill trees) and scaling up. We’re looking for a Full-Stack Engineer to accelerate development and help us ship features faster.

Requirements

What You’ll Do

  • Build and ship end-to-end features across our Next.js frontend and Supabase backend.
  • Extend the task/reward system (tasks, task_submissions, submission_reward_logs) with reviewer/admin dashboards and new reward mechanics.
  • Improve video upload & validation flows (resumable uploads, duration/fps checks, secure storage).
  • Strengthen Supabase schema & RLS policies to keep user data and rewards secure.
  • Develop integrations with KYC providers, storage/transcoding services, and blockchain APIs.
  • Contribute to NFT features (nfts, breed_logs, mint_logs) and wallet interactions.
  • Implement background jobs & queues for reward distribution, media processing, and KYC updates.
  • Add gamification features (XP, streaks, badges, skill trees) in both frontend UI and Supabase schema.
  • Maintain high engineering standards with clean CI/CD, testing, logging, and monitoring.

Must-Have Skills (3–5+ years)

  • Frontend:
    • TypeScript, React/Next.js (SSR/ISR), TailwindCSS.
    • State/data handling (React Query, Context/Zustand).
  • Backend:

    • Node.js/Deno APIs; secure webhook handling (idempotency, retries).
  • Data handling:
    • Strong SQL/Postgres (joins, indexes, constraints).
    • Designing relational schemas for dynamic applications.
  • Integrations:
    • Wallet connect (ethers/viem/wagmi), signature verification.
    • APIs for KYC, storage, video services, payments.
  • Security:
    • Role-based access control (RLS).
    • Input validation (Zod/Yup).
    • Secure handling of external webhooks.

Who You Are

  • 3–5+ years in full-stack product engineering.
  • Comfortable owning features across frontend, backend, and database.
  • Strong with Supabase/Postgres.
  • Obsessed with clean, secure data flows (RLS, idempotent jobs).
  • Thrives in a fast-moving startup (iterate weekly, ship features quickly).
