Full-Stack Web Developer (React + Backend + Analytics)

About us

We’re building Interview Assistant AI - a web-based AI product that helps people prepare for and go through interviews with more confidence.

Our product philosophy is Activation-First:

  • honest expectations from the first screen,
  • reduced first-time user anxiety,
  • safe practice before real interviews,
  • no hype, dark patterns, or fake metrics.

You’ll work with clear product specs, a focused scope, and a small product team that values calm, thoughtful execution.
 

What you’ll work on (Phase 1)

This role is focused on a short, clearly defined execution phase.

At a practical level, you’ll:

  • implement landing page and dashboard UI changes
    (no redesign, no copywriting - specs provided),
  • add PostHog analytics on the frontend,
  • implement backend events for:
    • interview lifecycle,
    • AI output generation,
    • activation and failure states.

The goal is to ship a clean activation flow and reliable analytics, without over-engineering.
 

How we like to work

We’re looking for a developer who is comfortable working from clear specs, and who also:

  • points out simpler or more efficient ways to implement things,
  • suggests better technical approaches (especially for analytics),
  • surfaces tradeoffs when an implementation choice could affect timeline, cost, or risk,
  • asks questions if something is ambiguous.

You won’t be expected to define product direction but your technical judgment is welcome and valued.
 

What this role is not

  • No UX redesign
  • No product discovery
  • No experiments or A/B testing
  • No growth dashboards
  • No rewriting copy

This is a focused execution phase with clear boundaries.
 

Tech stack & experience

Must have

  • React (or similar SPA framework)
  • Backend experience (Node.js or similar)
  • Experience with analytics tools (PostHog, Segment, Amplitude, etc.)
  • Comfortable working with an existing codebase
  • Clear written communication

Nice to have

  • AI / LLM integrations
  • Stripe or payments experience (future phase)
     

What’s next

Phase 1 is short and activation-focused.

If things go well, there may be follow-up work later (AI model updates, API / Stripe work), but the immediate focus is Phase 1 only.
 

Please be ready to answer a few short questions after the first contact.
