    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.

    Who we are

     

    OWOX is a B2B SaaS platform delivering the last mile of self-service analytics.

    Data analysts and business stakeholders spend 1.2 billion hours every year on reporting, yet stakeholders still complain they can’t get data they trust. Analysts are stuck in service-desk mode, endlessly adjusting reports instead of driving insights.

    OWOX changes this. Our patented technology reduces the cost per reporting request by 20x and increases reporting velocity by 50x, enabling stakeholders to get instant, trusted answers on top of spreadsheet-ready data.

    In 2025, OWOX served 3+ million reporting requests for 2,100+ users. Today, we work with 50+ paying customers, driving 105% YoY Net Dollar Retention.

    • consistently realize business value from OWOX;
    • expand their usage and contracts over time;
    • see OWOX as a strategic analytics partner, not just a tool.

    Your success will be measured by three outcomes:

    1. Net Dollar Retention (NDR) in USD > 100%.
    2. Regular, value-driven engagement with Economic Buyers on key accounts.
    3. Growth of Monthly Active Data Marts as OWOX’s North Star product metric across the customers.

     

    What you will do

     

    • Own Net Dollar Retention (NDR > 100%) by driving customer retention, expansion, and renewals.
    • Build and maintain direct, regular relationships with Economic Buyers, aligning OWOX with their business goals and success metrics.
    • Drive product adoption and growth of Monthly Active Data Marts (North Star metric) through activation of new use cases and features.
    • Embed OWOX into customers’ decision-making by translating analytics capabilities into clear business value and measurable outcomes.
    • Lead and scale the Customer Success team (CS Managers + Data Analysts), setting engagement models, playbooks, and success standards.

     

    What success looks like in 6 months

     

    • Net Dollar Retention is stable and predictable, with clear visibility into renewal and expansion drivers across the customer base.
    • Economic Buyers are identified and regularly engaged on all key accounts, with conversations focused on business outcomes and value realization.
    • Customer Success operates with clear segmentation, engagement cadence, and success plans, consistently applied across the team.
    • Customers actively adopt new OWOX use cases, driving month-over-month growth of Monthly Active Data Marts.
    • The CS team provides structured, actionable feedback to the Product team, grounded in real customer and Economic Buyer needs.

     

    Skills & experience

     

    Required:

    • Fluent English (C1 or higher).
    • Advanced Google Sheets / Excel skills.
    • Experience working directly with Economic Buyers (C-level, Heads of Growth, Marketing, Revenue).
    • Strong understanding of analytics use cases for eCommerce, marketing, and product teams.
    • Proven experience in customer retention, expansion, and value realization.

     

    Highly appreciated:

    • SQL experience.
    • Google Cloud Platform / BigQuery experience.
    • Looker Studio experience.
    • Stripe billing and subscription management experience.
    • Background in data analytics, consulting, or analytics-driven SaaS.

     

    What your success looks like

     

    Every big journey needs a measurable plan.

    1. Application review within 2 business days.
    2. Interview with Recruiter β€” intro to Company, soft skills & culture fit check.
    3. Interview with CRO β€” focus on customer growth, revenue ownership, and Economic Buyer engagement.
    4. Interview with CEO β€” culture fit and strategic thinking.
    5. Final decision and offer within 3-5 business days.

    ‍

    At OWOX, you will discover a great environment for professional growth, a supportive atmosphere, and the opportunity to collaborate with experts in their field. Additionally, you will enhance the value of your work by leveraging the power of data analytics.

    Platforms knowledge (as proficiency requirement)

    • Proficient with voice-agent platforms such as Vapi, Retell, and/or LiveKit(or equivalent)

    TTS & voice
    Strong knowledge of TTS models and practical tradeoffs (quality vs latency vs cost)

    • Experience creating or integrating custom voices (where allowed/ethical/consented)

     

    Performance & deployment
    Proven ability to optimize latency and cost

    • Experience building infrastructure for fast agent development and deployment
    • Experience with evaluation of calls using transcripts:
