We’re building and iterating fast on a performance-focused marketing funnel + app experience. We use agentic coding (AI-assisted development) to move quickly, but we care equally about quality, maintainability, analytics correctness, and production reliability. What you’ll work on (examples from our current stack) 1. [Next.js](https://next.js/) app-router product + funnel with localized routes (multi-language i18n). 2. Onboarding + checkout flows (subscriptions/payments) and post-checkout success handling. 3. Supabase: database migrations, RLS-aware data access patterns, server-side integrations, and edge/server functions. 4. Stripe: revenue/trial reporting scripts, webhook-style flows, and subscription lifecycle handling. 5. PostHog analytics: event taxonomy discipline, instrumentation, backfills, and data validation. - PWA + push notifications: service worker changes, scheduling/cron-like workflows, and notification delivery reliability. Responsibilities - Ship end-to-end product features: from user flow design implementation - QA - analytics to release. - Use agentic coding effectively: create clear specs/prompts, iterate quickly, and verify outputs with tests + review. - Maintain quality at speed: - Write/extend tests for critical flows (auth/onboarding/checkout/notifications) - Keep code structured, readable, and production-safe (no “AI spaghetti”). - Own instrumentation: define events/properties carefully, ensure consistency, and prevent breaking reporting. - Work across the full stack: frontend, backend routes, database migrations, and integrations. Must-have experience - Product-building track record: you’ve shipped real customer-facing funnels/apps and can talk through trade-offs. - Strong TypeScript + modern React/Next.js experience (App Router preferred). - Agentic coding proficiency: - You’ve used tools like Cursor/Claude/ChatGPT/Copilot in real projects. - You know how to validate AI-generated code (tests, diffs, edge cases, instrumentation checks). - Supabase experience (Postgres, migrations, auth patterns; RLS awareness is a big plus). - Payments integration experience (Stripe subscriptions strongly preferred). - Analytics discipline (PostHog/Segment/GA): event naming, properties, debugging, and maintaining data integrity. Nice-to-haves - PWA/service worker experience and web push notification workflows. - Familiarity with A/B testing, variants, and CRO iteration loops. - Experience with cron/queued jobs patterns and reliability/observability. - i18n/localization and multi-locale routing experience. How we work (what we expect) - Move fast, but verify: tests for core flows, careful rollout, and production-safe defaults. - Strong product sense: you can propose improvements, not just implement tickets. - Clear communication: short updates, crisp PRs, and pragmatic decision-making. What success looks like (first 30–60 days) - Ship multiple improvements to onboarding/checkout/funnel with clean, reviewable code. - Tighten analytics (events/properties consistent, dashboards match reality, backfills when needed). - Improve reliability of notifications/PWA behavior across environments. - Establish a repeatable agentic coding workflow that increases speed without increasing bugs. Interview / evaluation - Short async screen (past work + how you use AI to ship). - Practical task (small, real slice: [Next.js](https://next.js/) + Supabase/Stripe/PostHog-style change). - Working session (pairing on an actual backlog item). Logistics - Engagement: Contract or contract-to-hire (flexible). - Time zone: Flexible overlap preferred. - Compensation: Based on experience and availability. How to apply Send: - 1–3 relevant links (repos, shipped products, case studies). - In the Subject line write “I KNOW AGENTIC CODING” to show you attentiveness to details - A short note on how you use agentic coding in production (workflow + safeguards). - Your experience with [Next.js](https://next.js/) + Supabase + Stripe + analytics (even brief bullet points are fine).
