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.

Description

About Unto Labs

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.
Responsibilities

Responsibilities

  • 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.
