Head of Product @ Koast.ai

Headquarters: Tampa, Florida
URL: https://koast.ai
Role: Head of Product | Contract, 20 hrs/week to start, growing into full-time | Remote (US overlapping hours) | Reports to the CEO

The Short Version

Koast is the AI operating layer for teams that run Meta ads at volume. Agencies, in-house media buying teams, and enterprise buyers managing 10+ ad accounts and launching 50+ ads a week use Koast to launch faster, automate optimizations off real attribution data, and see every account from one hub. The Koast Agent is the next layer: an AI that reads the account, spots what matters, and acts inside guardrails.

We are a small team shipping fast. The product is live, customers are paying, a Whop partnership just onboarded a wave of new users, and the Agent build is underway. What we do not have is one person who owns the product end to end: what gets built, why, in what order, and whether it actually landed.

This role starts at 20 hours a week on contract. If you are the right person, it becomes the full-time product seat at Koast.

What You Will Own

Discovery that finds the real problem: You will sit in on enterprise sales calls and onboarding sessions, run discovery with agencies and media buying teams, and figure out what they are actually trying to get done. If a feature does not serve a job, it does not get built.
Specs that engineering can execute without a meeting: You will write PRDs and Shortcut tickets that define the behavior, edge cases, data dependencies (Meta API limits, Hyros/Cometly attribution feeds, Whop account provisioning), and acceptance criteria.
The queue: You own the "Up Next" column. You will keep engineering fed so they are never blocked and maintain a view of what is discussed in Slack, support, and QA that does not yet have a ticket.
Evidence over opinion: You will run the user-behavior audit using PostHog, Intercom, session replays, and support threads. You will bring numbers to every prioritization argument.
Delivery from spec to shipped: You will handle governance, milestones, release notes, and the customer conversation after it ships.
Technical judgement in a non-deterministic product: You will make product calls regarding what the Koast Agent is allowed to do, what it must never do, and how we measure success.

What You Will Do Week to Week

Run discovery sessions with prospects and customers and turn them into scoped, execution-ready PRDs.
Surface technical risk early: undocumented API behavior, missing data, or assumptions that will not survive a real ad account.
Write and groom Shortcut tickets with enough detail for an engineer or Claude Code to ship without a follow-up question.
Partner with engineering on feasibility, sequencing, and cutting scope to what ships this week.
Own success metrics per feature and report on them after launch.
Be the customer's point of contact through onboarding and rollout for enterprise accounts.
Write short updates for the CEO, the customer, and the engineer.
Say "we should not build this" when the data says so.

What Sets You Apart

You have run Meta ads or sat close enough to a media buyer to know what a 2am budget change feels like.
You have shipped B2B software end to end in a small team.
You have worked on or with AI/ML products where the output is not deterministic and you had to define what "correct" means.
Senior engineers take you seriously because you read the API docs before the meeting.
You write tightly; your PRDs are short and clear.
You are comfortable being the only product person in the room and the one who gets blamed when the roadmap is wrong.

Requirements

4+ years in product management on B2B SaaS, with full-lifecycle ownership from discovery through iteration.
Hands-on familiarity with Meta Ads Manager and the Marketing API. Agency or performance marketing background strongly preferred.
Strong technical fluency: you can read an API response, reason about data models, and understand why a rate limit changes the feature design.
Experience working with attribution or analytics data (Hyros, Cometly, Triple Whale, Northbeam, or similar) is a plus.
Experience writing specs consumed by AI coding agents is a plus; willingness to learn it is required.
Comfortable in Shortcut, PostHog, Intercom, Slack, and Notion, or able to get there in a week.
Available 20 hours a week during US business hours, with the intent to go full-time.

How You Work

Mastery: You keep sharpening the craft: tighter specs, sharper questions, cleaner calls.
Push the Boundaries: You take on the ambitious version of the problem.
Embrace the Challenge: When a launch flow breaks for a customer at 9pm, you are in the thread.
Responsibility: You own your commitments.
Dedication: You dive into the hard, unglamorous problems and iterate until they are solved.
Collaboration: You write clearly, share what you learn, and make others smarter for having worked with you.

Why Koast

Early-stage impact: You will be the first product seat.
AI and ads at scale: Work on the frontier of AI-driven media buying.
Growth and ownership: Start at 20 hours a week on contract, growing into the full-time Head of Product seat with potential for equity.
Remote and flexible: Work from anywhere during US hours.

How to Apply

Record a Loom, five minutes or less, covering these four things in order:

Show us an ad account: Screen-share any Meta ad account you have access to (blur what you need). Tell us the last change you made and why.
One thing you would kill: A feature you shipped that you would remove today, and what you learned from it.
One spec: Screen-share a PRD or ticket you wrote that an engineer shipped without asking a follow-up question.
Where Koast fits: Sixty seconds on where a tool like Koast changes a media buyer's week, and where it does not.

Email the Loom link and your LinkedIn or resume to jobs@koast.ai with the subject line "Scale with Koast".

No cover letters. We watch the Loom first and read the resume second. Applications without the video are not reviewed.
