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 BitTorrent, we create robust peer-to-peer connections and data replication systems that set the foundation for a decentralized web.

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.

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.
Our client is a remote product studio that builds MVPs and custom software for startups and companies past the idea stage.
Clients hire them for a fixed-scope MVP or for a product team billed by the two-week sprint, and the whole team uses AI coding tools every day.
They've been at it since **** and were profitable in ****, with a 30% net margin.
After building their own AI systems,



they tripled monthly revenue with the same team size.
Clients rate them 4.9 out of 5 in verified reviews, and the startups they build for have raised more than $25M in venture funding.
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 TypeScript 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, TypeScript 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
