Founding Product Engineer

Interfere is building the self-healing layer of the internet: software that detects issues, diagnoses root causes, and ships fixes before anyone notices something’s broken. The goal is to empower founders, product managers, and designers to understand how the product they're building actually works in the real world. Software runs civilization. When it breaks, the world stutters. We're building its immune system. This is not a normal job – it demands taste, intensity, and obsession. Difficulty wakes the genius.

The Moment

AI has democratized shipping code, but excellence remains scarce. We're creating the infrastructure that makes product excellence no longer aspirational but inevitable and expected. We've raised over $5.1M from world class investors like Y Combinator, Vercel Ventures, Hummingbird, Designer Fund, and many others to turn our vision into reality. This isn't about incremental improvements, but about fundamentally changing how reliable software gets built.

The Role

As a Founding Engineer, you will own end-to-end features that define how the greatest teams build and iterate upon their products. You'll architect and ship the foundational systems powering our proprietary data pipeline and interfaces that push the boundaries of what's possible.

The Work

You'll operate at the intersection of the impossible and the inevitable. This role demands:

Depth over breadth – You'll go deeper into problems than most think necessary, finding elegance where others accept complexity

Craft at velocity – Ship exceptional work quickly without compromising on quality that matters. Both form and function, never just one or the other

"High Standards Win" – Question everything, rebuild from scratch when needed, never accept "that's how it's done" or "good enough"

Ownership without borders – Your domain is whatever needs doing to make Interfere exceptional. No excuses

What You'll Build

Core detection and diagnosis systems that understand codebases at scale

Developer-facing interfaces that make complex systems feel intuitive

Infrastructure that ships fixes autonomously and safely

APIs and integrations that meet developers where they are

The foundation of a platform that will handle billions of events

What We're Looking For

Immense pride in the work you do and a desire to build the best products on earth

Builders with taste – You know the difference between good and great, and you can't sleep until you've achieved the latter

Systems thinkers – You see patterns others miss

Relentless learners – You dive into unfamiliar domains and emerge with either expertise or a delusional drive to acquire it

Clear communicators – Complex ideas become seem obvious when they find their way into your hands

Domain experts – True fluency & expertise in Next.js, TypeScript, and modern JS development tooling.

Nice to Have

Experience with developer tools, observability platforms, or infrastructure

Deep knowledge of TypeScript/Node.js, React, or distributed systems

Track record of being on a team that shipped products developers love

Portfolio of work that demonstrates exceptionality - open source contributions, side projects, or production systems you've built

What We Offer

Founding team equity and competitive compensation

Complete ownership of meaningful work

Health, dental, and vision coverage

Visa sponsorship for exceptional international candidates

The opportunity to define the technical foundation of a category-defining company

How We Work

We're in-person in New York City, and believe proximity accelerates everything that matters, but we'll gladly help you move here. Send us evidence of exceptional work you've shipped - GitHub repos, live products, technical writing - and a note about why Interfere resonates with you. We value proof of who you can be over who you've been.
