Job summary

Tether is seeking a Product Engineering Lead to drive Keet, a peer-to-peer messaging app built on Holepunch. You’ll lead API and frontend teams, partner with product, and shape architecture to scale to billions of users.

You’ll own technical design, maintain high engineering standards, and mentor leads. The role blends engineering leadership (70%) with product collaboration (30%), and requires deep React/JS and distributed systems experience.

Qualifications

• Experience shipping consumer products at speed.
• Strong product sense and ability to partner with PMs.
• Intuition for distributed, local-first systems.
• Deep JavaScript and React expertise.
• Initiative, curiosity, resilience, and ability to give/receive direct critique.
• Bonus: experience with local-first apps, CRDTs or sync engines.

Responsibilities

• Run the API and frontend teams day to day: unblocking, reviewing, and keeping them shipping.
• Set and hold a high engineering bar for performance, reliability, and clean APIs.
• Own the technical design of features and the API surface between Keet's core and the app.
• Make sure the API team works closely with deep tech teams on code reviews, design, and engine touches.
• Work alongside Keet's product managers to turn vision and roadmap into scoped, buildable work.
• Push back when scope and reality don't match, and propose better paths when they exist.
• Bring an engineering perspective to product decisions, especially where P2P opens doors centralized apps can't.
• Help the team move fast, using AI tools and quick prototypes to validate ideas before committing to them.
• Create clarity around team goals and ensure everyone knows what success looks like.
• Mentor team leads to build strong operating systems and grow as leaders.
• Lead by example: roll up your sleeves when needed and step back when they’re ready to own it.
