We are looking for a Lead Blockchain Engineer to help architect and build secure, scalable blockchain infrastructure and products.

Tasks

You will own technical implementation across blockchain systems, smart contract architecture, integrations, and protocol-level infrastructure.

We are looking for builders with strong execution ability, systems thinking, and production deployment experience.

Requirements

Must-Have

Strong Plus

This Role Is NOT For

Real Equity: We treat early team members like partners. You’ll receive meaningful equity so the upside you help create is shared.
Direct Access to Leadership: You are part of the core conversation. You will work side by side with the CEO and founders every day to solve hard problems and set the strategy.
Work on Hard, Emerging Problems: We are building infrastructure for AI agents operating on sensitive, real-time data without relying on centralized black box platforms. While parts of this ecosystem exist, the architecture for doing it securely and reliably at scale is still evolving.
Small Team, High Output: We believe the best teams are small and extremely capable. AI tools increase individual leverage, so we hire fewer people and expect a much higher level of ownership and output.
Autonomy With Accountability: We hire people who don’t wait for permission to solve problems. If you see a better way to build something, you’re expected to propose it and ship it.
Remote With Real Collaboration: We are a remote-first team but believe strong collaboration requires real interaction. The team meets regularly in San Francisco and Europe for focused building sessions and hackathons.

Our Hiring Process

We move fast, stay transparent, and focus on real collaboration. Here’s what the process looks like:

Intro Call – A quick chat to align on expectations, interests, and team fit.
Technical Deep Dive – A focused conversation with our Engineering Manager to explore your technical thinking and past work.
CEO Interview – A strategic discussion around vision, mindset, and long-term alignment.
Reference Collection – We’ll speak with a few people you’ve worked closely with.
Paid Trial (~5 Days) – A short, real-world engagement so we can see how we work together — happening in parallel with offer and terms discussion.
