    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.
