About the job
Our pioneering P2P development platform, built on our open-source technology stack, Pear, eliminates the need for traditional server infrastructure. Pear platform facilitates direct deployment of applications from the developer’s machine to the user, enabling seamless scalability and performance.



By leveraging Node.js-based technology akin to Bit Torrent, we create robust peer-to-peer connections and data replication systems that set the foundation for a decentralized web. Learn more about Pear: docs.pears.com Keet, our flagship P2P communications app, is the first step towards this new era. It exemplifies the potential of P2P technology in everyday applications, from messaging and file sharing to complex collaborative environments, all while maintaining user sovereignty over personal data. Learn more about Keet: keet.io Responsibilities
In this role, you will be responsible for developing and maintaining Keet Desktop, our cross-platform P2P communications application built with React and running on the Pear runtime. You'll work on everything from UI/UX implementation to performance optimization, helping shape the future of decentralized communication. Strong competency in state management (Redux, Redux Toolkit, Zustand, or similar). Ability to write modular, maintainable, and well tested code. Solid skillset in testing & debugging complex frontend applications. Deep interest or experience with P2P technologies or distributed systems. Comfort working in a remote, globally distributed team; good communication skills. Preferred Qualifications
Experience with desktop application development (Electron, Tauri, or similar runtimes). Familiarity with video/audio APIs (WebRTC, media streams) and real-time communication. Demonstrated ability to optimize UI performance: rendering, memory management. Bonus: Past contributions to OSS projects, especially in P2P or decentralized tech. Your Role
You'll join the team building workflow software for one of the studio's clients: a live product that needs new workflow features while the existing ones keep running. The client's own engineers commit to the same repo, so every new table, permission and workflow goes in next to code someone else is changing. The weight is on the server side, from the SQL database on Azure up through the API,



and you also build the React and Type Script screens that sit on top.AI coding tools draft most of the specs, tests and migrations. You direct them, read every diff line by line, and answer for what merges. If you'd rather write most of the code by hand, this probably isn't the right seat. You report to the studio's leadership and work day to day with the lead developer and the product manager, who sets the acceptance criteria for each sprint. Success means delivering four to five features per two-week sprint, each verified before merge, and owning one area end to end (such as the task engine or the legacy migration) without breaking a live feature. You Bring:
4+ years building full-stack web applications and releasing them to production. Experience working in a codebase you didn't write, learning its conventions before changing it. Hands-on work on workflow software where different user roles see different data, with approvals, task queues or state machines and an audit log or versioned history. React, Type Script and SQL on Azure, including schema design and migrations. Daily use of Cursor, Claude Code or a similar AI coding tool on production work, with tests and CI behind it. Clear written and spoken English. Experience delivering in fixed-scope sprints with branches, code review and feature flags. Bonus Points:
Work in a regulated setting such as finance, health or insurance.A migration from a legacy system, with reconciliation and duplicate review. Time as an outside vendor committing to a client's repo. Project rules, custom prompts or agent setups for AI coding tools that your team adopted. Spanish, since the platform is bilingual. What's Offered:
Fully remote contractor role from LATAM, full time at about 40 hours a week. Core hours in US time zones, so your day overlaps with the lead developer and the product manager. An area of the product to own end to end, with your schema designs reviewed by the lead developer and the client's engineers.A team where AI-first delivery is already the daily routine, with tests, CI and feature flags as part of the normal process.A start in early November. Interview Process:
1. Intro Call: 30 minutes with atomic HR on your background and goals.2. Leadership Screening: A short call, possibly with an async part first.3. Product and Developer Conversation: How you take features from acceptance criteria to merge.4. Take-Home Test: One feature like the real scope, built and checked.
