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).
