Founding Engineer

Preferred

• : prior fintech/payments experience or blockchain/distributed-ledger exposure

The role

We are hiring a Founding Engineer to take ownership of core platform architecture as we rebuild for a system roughly 50x the scale of what we had before. You'll design and scale distributed systems from scratch (this is deep systems-architecture work, not feature development on an existing system.) You will work directly with the Head of Development and a small team of engineers to ship production systems operating at global scale.

Non-negotiable

10+ years of professional software engineering experience, with real, hands-on ownership of designing and scaling a production system from scratch. You can describe specific production incidents at scale (what broke, why, and what you changed) not just system-design-interview theory.

Deep TypeScript/Node.js expertise. You should be able to design a NestJS microservice from scratch, not just work in one.

Strong PostgreSQL skills. You can design schemas for complex, high-throughput production data, write migrations, and reason about transaction isolation and locking.

Experience with event-driven architectures (Kafka, RabbitMQ, or similar). You understand the difference between request-reply and fire-and-forget patterns and when to use each.

You ship. You can take a spec document and turn it into production code without waiting for someone to break it into small tasks.

Nice to have, not required

AI-augmented engineering (required mindset)

We expect every engineer at Share to use AI tools as a daily part of their workflow. This is how we operate. Our entire project planning, specification, and documentation process runs through AI-assisted sessions. Our codebase includes AI-readable context files. We use Claude for architecture decisions, code review, spec generation, and technical writing.

What this means for you

• You already use AI coding assistants (Claude, Cursor, Copilot, or similar) daily and can articulate how they change your workflow.
• You are comfortable working with AI-generated specifications and can critically evaluate them, push back where they are wrong, and extend them where they are incomplete.
• You see AI as a force multiplier that lets a small team operate at the capacity of a much larger one. You are not threatened by it; you are faster because of it.
• You are willing to contribute to improving our AI-assisted workflows

Additional Benefits
