Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and implement high-performance system-level components for a base-layer blockchain infrastructure. Focus on optimizing commodity hardware for low-latency services and maintaining secure networking protocols and cryptographic primitives.
Requires a Master's degree in Computer Science, Economics, or a related field with at least 10 years of experience in systems engineering. Must have expertise in C, C++, Rust, and the development of distributed ledger technologies.
Unto Labs is a team of low-level engineers pushing distributed systems to the physical limits of modern hardware. We’re reimagining blockchains, from core consensus primitives to performance-tuned networking stacks, in the service of global scale applications.
We're seeking a Senior Systems Software Engineer to take on the toughest challenges in distributed, high-performance computing. You'll be responsible for designing and building key parts of a base-layer blockchain, focused on juicing every last ounce of performance from commodity hardware. As a member of our fast-paced team, you'll work across the entire modern blockchain stack, including cryptography, consensus, distributed systems, and core kernels.
Design and implement system-level components for blockchain infrastructure using C, C++, and Rust.
Maintain strong emphasis on computer systems analysis and implementation.
Gather requirements for high-throughput, low-latency (≤ 200 ms p95) services; design distributed systems that meet 99.9 % availability SLAs.
Perform benchmarking and performance profiling to enhance execution efficiency.
Specify, version, and maintain public and internal APIs plus JSON-RPC/gRPC endpoints.
Document interfaces and generate strongly typed client libraries.
Collaborate on the development of secure, low-latency networking protocols and cryptographic primitives. Build fault-tolerant ETL pipelines that transform on-chain events into query optimized relational & NoSQL stores.
Tune indexes for millisecond reads.
Provision and scale commodity server fleets (on-prem & cloud).
Automate with Terraform/Kubernetes, monitor health, capacity, and SLOs. Migrate legacy computing pipelines to modern CI/CD frameworks.
Support the design of fault-tolerant systems with advanced debugging, logging, and error recovery functionality.
Model token- economic incentives, auction fee markets, and validator/operator behaviors; prototype algorithms and run agent-based simulations.
Leverage generative-AI coding agents, static analyzers, and self-healing runbooks to accelerate delivery and cut MTTR.
Review performance metrics to refine software components for memory and process or efficiency.
Profile CPU, I/O, and network paths; execute load-tests; instrument metrics/tracing/logs; drive post-mortems and capacity plans.
Maintain and manage a performant suite of APIs, SDKs, and developer tools for consumption by external developers.
Integrate cryptographic primitives, secure key management, vulnerability scanning, and incident response playbooks.
Write RFCs, lead design reviews, mentor junior engineers, and coordinate cross-functional delivery with product, infra, and legal teams.
100% telecommuting/working from home permitted from various and unanticipated locations throughout the U.S.
This position requires a Master’s degree, or foreign equivalent, in Economics, Business Economics, Computer Science, or a related field.
10 years of experience as a Systems Engineer, Software Engineer, Software Developer, Information Technology Officer, or a related occupation
Additionally, the applicant must have employment experience with:
Systems programming in C, C++, and Rust;
Low-level performance optimization and hardware interfacing;
Distributed systems and threading runtimes;
CI/CD pipeline design using GitHub Actions and on-prem infrastructure;
Work with multiple systems, including web development platforms, high-performance computing systems, core operating system kernels, developer tools, and systems related to economic applications;
Develop distributed ledger technologies or crypto economic distributed systems.
Be at the forefront of blockchain technology, working on next-generation performance optimization, on a small, fast-moving, tight-knit team
Work with a team of experts with deep expertise in high-frequency trading and scaling developer ecosystems
Shape the architecture of a system designed to process millions of transactions per second
Access to cutting-edge hardware and development tools
Competitive salary ($213,512 - $220,000 USD)
Significant equity and upside potential
Flexible work environment
Unlimited vacation policy
Health insurance
Hardware and development tool allowance
