We are a venture backed company with a small engineering team and a short path from decision to production. The opportunity We are looking for a Software Engineer to take ownership of significant parts of the Plugin OS product surface, working closely with our CTO. This is a high autonomy role. You will own features from specification through to release across mobile, web and backend, rather than working from a groomed ticket queue.

Cursor, Claude Code and similar tools are a standard part of our workflow, and we license them for the whole team. We are interested in engineers who use these tools deliberately and get more done because of them. Equally, we expect the engineering judgement to review what is generated, recognise when it is wrong, and diagnose production issues on devices already deployed in venues. Please tell us how you work with these tools when you apply. Compensation and benefits ● Competitive monthly compensation in USD, benchmarked to experience and market ● Equity participation for early team members ● Flexible time off with no fixed annual allowance ● Health coverage, or a monthly stipend toward a local plan for candidates outside the US ● Full AI tooling and development software licensed by the company ● Meaningful ownership of a product operating at real scale Hiring process We do not run screening calls before seeing code.

It is how we assess candidates, and it replaces the usual screening call. Lightweight POS with remote menu control Build a Flutter project containing two applications sharing a single Firebase backend. POS application (tablet or web layout) Displays the active menu with item name, price, category and availability Selecting items builds an order with a running total Menu changes made from the manager application appear live, without a restart Manager application (phone layout) Create, edit and delete menu items Toggle items between available and sold out Changes propagate to the POS application in real time Expectations Flutter for both applications, Firestore as the backend Shared models and business logic across the two applications rather than duplicated code Basic Firestore security rules A README covering how to run the project, the reasoning behind your architecture, what you would build next with more time, and which AI tools you used and for what Scope: this is designed to take six to eight hours. How you scope your work is part of what we are assessing, so a smaller implementation that works correctly is a stronger submission than a larger one left unfinished. Note in the README anything you deliberately left out and why. Submission: upload to Google Drive and share the link with sumesh@pluginpromotions.com. Include the repository or an archive, plus a two to three minute screen recording showing both applications working together. You retain full ownership of anything you build for this exercise, and we will not use it.
