Build the
oracle.
We’re a pre-seed team shipping 19 Rust crates without outside capital. Four roles will shape the next two years. Founders work alongside hires daily — no middle management. Find your seat on the right.
Senior Backend Engineer (Rust / GNL)
Remote — LATAM/EU timezones
Own crates in the Geo-Neural Layer. Work directly with Carlos on the 4-layer ontology design. Type-safe Rust, Tokio async, TimescaleDB, A2A protocol implementation.
- Design and implement crates in the deino-gnl-* family
- Improve the audit manifest format and its reference implementation
- Contribute to deino-ledger (append-only event ledger on TimescaleDB)
- Write engineering blog posts about your work — we believe in public-facing engineering
- Top-5 hire: 5+ yrs senior backend, 2+ yrs production Rust (or strong systems background)
Pick a role · see what you’ll do, then apply straight from the panel.
The principles, not the perks.
Pre-seed teams don’t have org charts — they have problems waiting for the right person. Here’s how we operate while we’re still small enough to choose.
Buenos Aires HQ; team distributed. No fixed office. Two synchronous touchpoints per week.
Direct line to Carlos and Carolina. No middle layer. Founders work alongside hires daily.
Type safety, correctness, code that reasons clearly. We write Rust because we mean it.
Cash competitive for LATAM senior engineers (US-grade for hires in US/EU). Significant equity for the first 8 hires.
Standups. Sprint ceremonies. Headcount-as-status. We measure shipped work, not seat-time.
Public engineering. Open RFC for the audit manifest. Open core at V3. We believe the best work survives sunlight.
Why join now.
The first hires set the standard for everyone who follows. That’s the leverage — and the responsibility — of joining at pre-seed.
Top-table equity
Significant founding equity for the first 8 hires. US-grade equity bands regardless of where you live.
Real ownership
You own crates, not tickets. Pre-seed means your name is on the architecture, not buried in a backlog.
Public-facing work
Engineering blog posts, open RFCs, an open core at V3. Build a portfolio in the open, not behind an NDA.
No process tax
No standups, no sprint theatre, no headcount-as-status. Async by default; ship what matters.
We’re not hiring headcount — we’re hiring the eight people whose names end up on the oracle layer. The best work survives sunlight, so we build it in the open.— Carlos & Carolina, Founders
- Is DEINO remote?
- Yes — remote-first and async-default. Buenos Aires is the HQ, but the team is distributed with two synchronous touchpoints per week. There is no fixed office.
- What does compensation look like?
- Cash is competitive for senior LATAM engineers (US-grade for hires in the US/EU), with significant founding equity for the first 8 hires and US-grade equity bands regardless of location.
- What is the engineering culture?
- Type safety and correctness first — DEINO is built in Rust across 19 crates. The team practices public engineering: an open RFC for the audit manifest and an open core planned at V3. No standups, no sprint ceremonies.
- What if there is no open role that fits me?
- Send a note anyway to [email protected]. Pre-seed teams do not have org charts — they have problems waiting for the right person. Speculative applications are welcome.
