• 3+ years in leadership roles with direct P&L ownership (CPO, CMO, GM, CEO, Product Director, Head of Product, Head of Marketing, etc.)
• Product-Marketing Hybrid expertise: you can speak “Engineering” to the devs and “ROAS” to the marketers. You understand how a product change affects ad performance and vice versa
• Proven 0→1 and scale-stage experience: launching new units, restructuring businesses, scaling early-stage products to meaningful revenue, or founding a startup
• Strong financial acumen: you live in the dashboards. You understand the nuances of cohorts, LTV/CAC ratios, and churn rates in a subscription-based model
• Mentality: ownership, clarity, decisiveness, speed, and persistence
• Entrepreneurial mindset

What we offer:

• Full strategic and operational ownership of a multi-million ARR business unit

• Surface delivery risks, requirement conflicts, and quality concerns early, with proposed solutions
• Maintain strong documentation hygiene across tickets, flows, requirements, test artifacts, and release readiness

What We Are Looking For

Core Traits

• Extreme ownership: you take responsibility for outcomes, not just tasks
• Hands-on mentality: you are willing to get into the details, test things yourself, and solve problems directly
• High agency: you move work forward without needing constant direction
• Strong communicator: you can work effectively with executives, operators, engineers, and QA
• Structured thinker: you bring order to messy situations and ambiguous requirements
• Quality-minded: you care deeply about correctness, usability, and operational reliability

Required Skills & Experience

• Strong experience writing:
  • user stories
  • acceptance criteria
  • workflow diagrams
  • functional requirements
  • test cases
  • bug reports
• Solid understanding of software development lifecycles and Agile delivery
• Experience validating complex business workflows across multiple systems
• Ability to test both UI flows and backend behavior
• Experience working with APIs, JSON payloads, logs, and system integrations
• Strong bug reproduction, documentation, and defect triage skills
• Comfortable working directly with engineering teams on technical issues
• Experience with tools such as Jira, Confluence, Postman, SQL, Excel/Google Sheets, browser dev tools, and test management tools

• Experience with integration-heavy platforms, legacy systems, or data validation
• Familiarity with API testing, ETL/data verification, and cross-system reconciliation
• Experience supporting UAT with non-technical business stakeholders
• Exposure to automation testing frameworks is a plus, but this role is primarily for someone strong in manual, technical, investigative QA

What Success Looks Like

In this role, success means:

• Requirements are clear before engineering starts
• Engineering spends less time guessing and reworking
• Bugs are found early, documented well, and resolved quickly
• Stakeholders trust that the team understands their workflows
• Releases are better organized, better tested, and higher quality
• Risks are flagged early instead of becoming late surprises
• The team moves faster because someone is constantly creating clarity and accountability

Who You Are

You are the kind of person who:

• notices what others miss
• asks the hard questions early
• challenges vague requirements
• tests beyond the happy path
• follows through until the issue is truly closed
• does not say “that’s not my job”
• cares about the business outcome as much as the technical output

Why Join Us

You will join a team solving real operational and technical problems where quality, speed, and ownership matter. This role is ideal for someone who wants to be more than a note-taker or ticket manager. You will have real influence on how products are defined, built, validated, and delivered.
