At Eulen Labs, we build products for the sovereign individual, with a focus on security, privacy, and technical excellence. We are looking for a battle-tested, hands-on architect to become the guardian of our core production systems.
The Role
This is a deeply technical, hands-on position for a master craftsperson who prefers architecting and shipping brilliant code to attending meetings.

Your mission: to ensure our systems run with unwavering stability and speed, enabling us to deploy frequently and safely.
Who We're Looking For
We are seeking an expert with 15+ years of software engineering experience in critical, high-volume environments. You are a pragmatist who lives and breathes automated testing, resilient architecture, and the relentless pursuit of improvement.

Unto Labs is developing the Thru Layer-1 blockchain (https://thru.org)
We recently announced $14.4 million in funding to make blockchains & digital assets useful for the world. Founded by Jump Crypto alumni and core contributors to the Solana protocol and the Firedancer client (https://github.com/firedancer-io/firedancer), we’re tackling fundamental scalability, performance, and usability challenges in distributed ledgers.
Our runtime conforms to the RISC-V specification—moving away from domain-specific VMs, DSLs, and bespoke compiler toolchains that limit developer and institutional adoption. You can write smart contracts and programs in any LLVM compatible programming language and reason about a standard ISA in RISC-V. Components are developed in C for maximal control over performance and resource usage.
We believe there is a unique window of opportunity to developer fairer, more accessible, and more global financial products on resilient public blockchains.
