Senior Systems Software Engineer

Join Unto Labs as a Senior Systems Software Engineer, focusing on high-performance computing and blockchain infrastructure. Work remotely and be part of a cutting-edge team optimizing distributed systems.

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.

• •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.

• •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
• •Conference and learning budget

• •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.
