Hi there,
I'm hiring in my team at Twin — Series A AI company (€12M raised), building an agent builder platform. The core infra is Rust, and I need someone who wants to own serious pieces of it.
Rust is not a "nice to have" here. It's the backbone of:
A remote browser infrastructure running at high concurrency
Low-level protocols between browser ↔ agents ↔ humans
A graph-based agent runtime that has to survive partial failure
Systems that stay fast, predictable, and debuggable at scale
This is not web CRUD. Design mistakes are expensive and correctness matters.
You'd work on things like async orchestration (task lifecycles, cancellation, backpressure), low-latency protocol design, failure-resistant architectures. Stack includes tokio, tonic, tracing, and internal crates — not a monolith.
What I'm looking for: you've shipped real Rust to production — or you're early in your career but learn fast and build relentlessly. You understand async Rust beyond "it compiles." You care about system boundaries, ownership, and failure modes. You can explain why you built something a certain way. You're comfortable without heavy specs or process.
Senior or junior — I care about signal, not years. If you're earlier in your career but have high agency and strong fundamentals, I'll put you through a real technical challenge and invest in getting you up to speed.
High-agency signal matters to me. Founded something — even if it failed? Served in the military? Competed at a high level in sport? Shipped a side project no one asked you to build? That tells me more than a polished CV ever will.
LLM experience is a plus, but systems thinking matters more.
This is not a research role, not a framework-gluing role. You'll shape what gets built, not just execute a backlog.
WW remote, small team, high ownership. €100K–€170K + equity.
If this sounds interesting — don't send a generic CV. Link something you built, explain a hard systems problem you've owned end-to-end, or tell me about something you committed to that was hard. That's enough to start a conversation.
DM me or reach out at gregory@twin.so — no cover letter needed.
