[Hiring] Senior Rust Engineer @Launch Legends

Role Description

We’re offering a unique opportunity to join Launch Legends (and Autheo) as a part-time Equity Cofounder. Founded in July 2021, Launch Legends is at the forefront of bridging Web3 blockchain technology with the next evolution of Web2 integration—bringing businesses on-chain through enterprise-grade solutions, DePIN innovations, and decentralized financial infrastructure.

Autheo is recruiting a Senior Rust Engineer to own memory-safe execution and cryptography on a chain that is already live. Mainnet has been up since May 14, 2026. Staking and fees settle on-chain. DevHub is open. The job is not to invent a ledger in a slide. It is to make the Rust path in the Eigensphere Engine something a protocol engineer can ship against, and something a DevHub user can call without reading the node.

You will build and harden Rust components for execution, cryptographic operations, and the developer surface around them:

• WASM-compatible runtime modules
• Proof and signature verification on the post-quantum roadmap (Kyber, Dilithium, Falcon)
• gRPC and GraphQL boundaries used by DevHub and cross-chain flows
• SDKs in Rust and JavaScript

You will sit with protocol, security, and DevRel. You will not own exchange listings, the OCC charter, or the product roadmap.

Key Responsibilities

• Execution and runtime:
  • Design and ship Rust modules in the Eigensphere execution path: deterministic WASM-compatible components, safe host calls, and clear resource limits for contract and DePIN compute tasks.
  • Profile hot paths on the live network and on replay. Report p50/p99 and allocation behavior.
• Cryptography on the live chain:
  • Implement and integrate post-quantum primitives already on the Autheo roadmap: Kyber / ML-KEM, Dilithium / ML-DSA, and Falcon / SLH-DSA.
  • Add field-level encryption and key-handling boundaries where Marketplace or TheoID metadata must move without exposing it.
• Cross-chain and service boundaries:
  • Own gRPC and GraphQL contracts for runtime and cross-chain operations, with schema evolution, idempotency, and backpressure.
  • Webhook and event delivery for DevHub and dApp consumers.
• Reliability on Mainnet:
  • Kubernetes deploys, circuit breakers, and readiness that match how the validator and API surface actually run.
  • Benchmarks in CI (criterion or equivalent) on the cryptographic and execution paths.
• Developer ecosystem:
  • Rust and JavaScript SDKs for the operations you ship, with a short path from docs to a working call.
  • Reviews, written design notes, and mentorship of the engineers on the same surface.

Qualifications

• Production Rust.
• Shipped backend services with gRPC or GraphQL.
• Distributed systems work you can defend: retries, idempotency, backpressure.
• Comfort in Kubernetes and a CI pipeline that builds and tests Rust.
• Ability to read a cryptographic spec and implement against test vectors.
• Post-quantum or zero-knowledge implementation experience is strongly preferred.
• Bachelor’s or Master’s in Computer Science or equivalent practical depth.

Preferred

• WASM runtimes (wasmtime or equivalent).
• Open-source Rust that a stranger can clone and run.
• A public artifact: a crate, a paper, a talk, or a design doc.

First 90 Days

• A written map of the Rust surface that is live versus stubbed.
• One runtime or cryptography path taken from “called in a branch” to “measured on replay, covered in CI, documented for DevHub.”
• Versioned gRPC or GraphQL contract for that path, with a Rust client and a JavaScript binding.
• OpenTelemetry on that path, and a short note on what the traces showed.
• A bench in CI for the hot function, with the number you are willing to put next to your name.

Compensation & Growth Path

This is a part-time equity / token-based cofounder opportunity. You will receive equity in Launch Legends, Autheo, and the WFO Creator Network, along with token allocations in the Autheo blockchain.

Salaried compensation is expected to begin within 4 to 5 months, following our node, token sales, or funding.
